Crashes involving motorised rickshaws in urban India: characteristics and injury patterns

Introduction

Motorised three-wheeled vehicles (motorised rickshaw) are popular in Asian countries including India. This study aims to describe the crash characteristics and injury patterns for motorised rickshaw occupants and the road users hit-by-motorised rickshaw in urban India.

Methods

Consecutive cases of road traffic crashes involving motorised rickshaw, irrespective of injury severity, whether alive or dead, presenting to the emergency departments of two large government hospitals and three branches of a private hospital in Hyderabad city were recruited. Crash characteristics, details of injuries, injury severity parameters and outcome were documented in detailed interviews.

Results

A total of 139 (18%) of the 781 participants recruited were injured as a motorised rickshaw occupant (11%) or were hit by a motorised rickshaw (7%) in 114 crashes involving motorised rickshaw. Amongst motorised rickshaw occupants, single-vehicle collisions (54%) were more frequent than multi-vehicle collisions (46%), with overturning of motorised rickshaw in 73% of the single-vehicle collisions. Mortality (12%), the mean Injury Severity Score (5.8) and rate of multiple injured (60%) indicated a substantial trauma load. No significant differences in injury pattern were found between motorised rickshaw occupants and hit-by-motorised rickshaw subjects, with the pattern being similar to that of the pedestrians and two-wheeled vehicle users. With bivariate analysis for motorised rickshaw occupants, the risk of fatal outcome (odds ratio (OR) 2.60, 95% confidence interval (CI): 0.64-10.54), upper limb injury (OR 2.25, 95% CI: 0.94-5.37) and multiple injuries (OR 2.03, 95% CI 0.85-4.83) was high, although not statistically significant in multi-motorised-vehicle collisions as compared with the single-vehicle collisions or overturning. The risk of having multiple injuries (OR 4.55, 95% CI: 1.15-17.95) was significantly higher in motorised rickshaw occupants involved in front collisions. Being a front-seat motorised rickshaw passenger in a vehicle collision increased the risk of having a fatal outcome (OR 7.37, 95% CI: 0.83-65.66) and a Glasgow coma score ≤ 12 (OR 2.21, 95% CI: 0.49-9.89), although not significantly when compared to the back-seat passengers.

Conclusion

These findings can assist with planning to deal with the consequences and prevention of road traffic injuries due to crashes involving motorised rickshaw, given the high use of these and substantial morbidity of related injuries in India. The need for improved understanding of the risk characteristics of motorised rickshaw is highlighted.     

Factors affecting anatomical region of injury, severity, and mortality for road trauma in a high-income developing country: Lessons for prevention

Objectives

To study the factors affecting anatomical region of injury, severity, and mortality among road users in United Arab Emirates so as to improve preventive measures.

Methods

Data of the Trauma Registry of Al Ain city were collected prospectively over 3 years (2003-2006) at the main trauma hospital. For traffic injuries, the following were assessed: gender, nationality, road user type, anatomical region(s) of injury, systolic blood pressure on admission, Glasgow Coma Scale (GCS), Injury Severity Score (ISS), and mortality. Analysis included frequencies, cross-tabulations, and logistic regression.

Results

There were 1070 patients, 89% male, 25% UAE nationals, and with a mean age of 31 years. Expatriates, mainly from non-Arabic speaking, low-income countries, accounted for 88% of injured pedestrians, whilst nationals were overrepresented among vehicle occupants (29%), and motorcyclists 37%. Injuries of the extremities and head were frequent among pedestrians, motorcyclists, and bicyclists, whilst head and spine injuries were most common among front and rear vehicle occupants and drivers. The median ISS was five for pedestrians and four for all other road user types, including rear vehicle occupants. The mean hospitalisation was 9.7 days; 13% of patients were admitted to ICU with mean stay of 6.5 days. Overall mortality was 4%; pedestrians accounted for 61% of deaths. Predictors of mortality were GCS (p < 0.001), ISS (p < 0.01) and systolic blood pressure on admission (p < 0.03).

Conclusions

Head injury was a major factor affecting mortality, followed by injury severity and hypotension. To reduce injury incidence and severity, legislation and education are needed to ensure use of seat belts by all vehicle occupants including rear passengers, high-visibility devices by other road users, helmets by motorcyclists and bicyclists, protective clothing and boots for motorcyclists, and traffic engineering for pedestrians.     

Occupant and crash characteristics in thoracic and lumbar spine injuries resulting from motor vehicle collisions

Background context

Motor vehicle collisions (MVC) are a leading cause of thoracic and lumbar (T and L) spine injuries. Mechanisms of injury in vehicular crashes that result in thoracic and lumbar fractures and the spectrum of injury in these occupants have not been extensively studied in the literature.

Purpose

The objective was to investigate the patterns of T and L spine injuries after MVC; correlate these patterns with restraint use, crash characteristics, and demographic variables; and study the associations of these injuries with general injury morbidity and fatality.

Study design/setting

The study design is a retrospective study of a prospectively gathered database.

Patient sample

Six hundred thirty-one occupants with T and L (T1–L5) spine injuries from 4,572 occupants included in the Crash Injury Research and Engineering Network (CIREN) database between 1996 and 2011 were included in this study.

Outcome measures

No clinical outcome measures were evaluated in this study.

Methods

The CIREN database includes moderate to severely injured occupants from MVC involving vehicles manufactured recently. Demographic, injury, and crash data from each patient were analyzed for correlations between patterns of T and L spine injuries, associated extraspinal injuries and overall injury severity score (ISS), type and use of seat belts, and other crash characteristics. T and L spine injuries patterns were categorized using a modified Denis' classification to include extension injuries as a separate entity.

Results

T and L spine injuries were identified in 631 of 4,572 vehicle occupants, of whom 299 sustained major injuries (including 21 extension injuries) and 332 sustained minor injuries. Flexion-distraction injuries were more prevalent in children and young adults and extension injuries in older adults (mean age, 65.7 years). Occupants with extension injuries had a mean body mass index of 36.0 and a fatality rate of 23.8%, much higher than the fatality rate for the entire cohort (10.9%). The most frequent extraspinal injuries (Abbreviated Injury Scale Grade 2 or more) associated with T and L spine injuries involved the chest (seen in 65.6% of 631 occupants). In contrast to occupants with major T and L spine injuries, those with minor T and L spine injuries showed a strikingly greater association with pelvic and abdominal injuries. Occupants with minor T and L spine injuries had a higher mean ISS (27.1) than those with major T and L spine injuries (25.6). Among occupants wearing a three-point seat belt, 35.3% sustained T and L spine injuries, whereas only 11.6% of the unbelted occupants sustained T and L spine injuries. Three-point belted individuals were more likely to sustain burst fractures, whereas two-point belted occupants sustained flexion-distraction injuries most often and unbelted occupants had a predilection for fracture-dislocations of the T and L spines. Three-point seat belts were protective against neurologic injury, higher ISS, and fatality.

Conclusions

T and L spine fracture patterns are influenced by the age of occupant and type and use of seat belts. Despite a reduction in overall injury severity and mortality, seat belt use is associated with an increased incidence of T and L spine fractures. Minor T and L spine fractures were associated with an increased likelihood of pelvic and abdominal injuries and higher ISSs, demonstrating their importance in predicting overall injury severity. Extension injuries occurred in older obese individuals and were associated with a high fatality rate. Future advancements in automobile safety engineering should address the need to reduce T and L spine injuries in belted occupants.     

Fatal child cervical spine injuries in motor vehicle collisions: Analysis using unique linked national datasets

Aim

To improve insight into fatal child cervical spine injuries (CSI) caused by motor vehicle collisions.

Method

Two large national mortality datasets were linked at the level of the individual decedent to analyse and compare anatomical injuries and vehicle crash characteristics for fatally injured child occupants.

Results

Cervical spine injury was identified among 176 of 6065 child (age 0-15 years) motor vehicle occupant fatalities. Presence compared with absence of CSI had significant association with female gender, traumatic brain injury and seat restraint, but not with age, vehicle model, year or type, exposure to airbag, severe vehicle intrusion, collision speed or direction, drivability of the vehicle or seating position.

Conclusions

Cervical spine injury, which was uncommon in the studied subset of child decedents, was associated with female gender, the use of passenger restraints and the presence of traumatic brain injury.     

The cost of sustaining playground related extremity fractures in Singapore

Purpose

To study the cost of sustaining a fracture of the extremity caused by playground equipment. These costs include financial, psychological, clinical and others like loss of school days.

Method

This is a prospective study of 226 children seen at the Paediatric Orthopaedic Department for a 1-year period starting June 2005. Once confirmed to have a playground related fracture by the Orthopaedic specialist, three sets of data are collected. First is the clinical data. Second is the playground related data. This is done on site independently by another investigator. Third is the radiological data, which is assessed independently by an Orthopaedic surgeon to ensure consistency.

Results

Out of the 226 children seen, two-thirds were boys. The average age was 7.5 years. 35.8% were forearm fractures and 28.8% were supracondylar fractures with the rest being mostly fractures in the upper limb. 64.2% were treated with immobilisation only whilst 24.2% required closed manipulation and reduction. 1.2% required admission for treatment of their fractures. The average period of cast immobilisation was 34 days. The average number of consults, including that at the emergency department, was 4 with an average length of follow up of 67.2 days.Based on the above, in our institution, the average cost for outpatient treatment would be about S$680.00 (US$485.71) (US$1.00 = S$1.40; 1/1/2010) per injury. The inpatient cost for non-surgical treatment cost would be S$1000.00 and for surgical stabilisation the average cost would be S$3300.00 (US$2357.14).

Conclusion

Playgrounds are meant for children to play safely. Yet, there appears to be a significant number of injuries sustained. Whilst these fractures are relatively minor, requiring outpatient treatment, there are costs. Besides the financial costs, there are hidden psychological costs of loss of school days and inability to participate in sports. Finally, as with any injury, there can be long term complications which present further clinical costs.

Significance

Most studies on playground injuries tend to concentrate on the equipment and very superficially cover the clinical aspects, less so the costs. This paper looks at the clinical aspects in greater depth and emphasises that there are significant costs, beyond financial, when a child sustains a playground injury. The next thing to do is to examine what playgrounds factors significantly contribute to these injuries and remedy them when planning the construction of playgrounds.     

The epidemiology of BCVI at a single state trauma centre

Background

Blunt carotid and vertebral artery injury (BCVI) is a relatively uncommon but potentially devastating injury. The aim of our study was to highlight the incidence, patterns, presentation and associations of BCVI at our institution.

Methods

Retrospective data between 1st January 2003 and 31st December 2006 was obtained from The Alfred Hospital's health information system, patient medical records and the Department of Neurosurgery's database. Injuries were graded using the Denver grading scale.

Results

67 patients (0.64%) out of 10,417 minor and major trauma admissions, were diagnosed with BCVI. 33 (49%) sustained blunt carotid and 34 (51%) sustained blunt vertebral injuries. Motor vehicle accident (MVA) was the cause in 43 out of 67. 35% had associated head injury whilst 57% had concurrent cervical spine fractures. Odds ratio analysis showed that MVA victims with concomitant upper cervical spine injury were 22.9 times more likely to suffer BCVI than those without such risk factors. Approximately 50% of patients had a Glasgow coma score of 14 or less (GCS ≤ 14). Grade 4 BCVI was most common. Stroke occurred in 22 (32%) and mortality in 14 (20%).

Conclusion

BCVI although infrequent, is a serious injury. Our study suggests that MVA patients with cervical spine fractures especially of the upper C-spine are at much higher risk of BCVI than those without such injuries.     

Traumatic urethral injuries: Does the digital rectal examination really help us?

Introduction

The digital rectal examination (DRE) has been commonly employed as a trauma screening tool since the inception of the ATLS program. Because of weak evidence, its utility as a screening test has recently been questioned. The primary goal of this study was to identify the sensitivity of the DRE for detecting blunt urethral injuries in a level 1 trauma center. The secondary goal was to evaluate the interaction of DRE with additional clinical indices of urethral trauma.

Methods

A retrospective review of all blunt injured patients diagnosed with a urethral disruption at an urban level 1 trauma center from 1995 to 2008 was performed. Urethral injuries were diagnosed by retrograde urethrogram, urethroscopy and operative exploration. Demographics and injury data were collected. The value of the DRE in diagnosing urethral trauma was assessed (p = 0.05).

Results

Urethral injuries were diagnosed in 41 male patients (mean age = 39 years), 34 (83%) of whom were injured via a motor vehicle (median ISS = 21). Associated injuries were present in 40 (95%) patients, including 39 (95%) pelvic fractures. No clinical signs of urethral injury were evident on initial examination in 25 (61%) patients. All patients had hematuria after catheter insertion. An abnormal prostate on DRE, blood at the urethral meatus, and hematuria prior to catheter insertion was present in 1 (2%), 8 (20%) and 7 (17%) patients, respectively. Both meatal blood and hematuria were better screening tests than the DRE (p < 0.05).

Discussion

The sensitivity of the DRE for identifying urethral disruption is 2%. The majority of patients with urethral trauma undergo urinary catheterization prior to diagnosis of the injury. Additional signs of disruption including meatal blood and hematuria detected prior to catheter insertion are also infrequent. While the DRE remains clinically indicated in patients with penetrating trauma in the vicinity of the rectum, pelvic fractures, and spinal cord injuries, it appears to be insensitive for detecting blunt urethral injuries.     

Bicycle-related injuries in children: Disturbing profile of a growing problem

Context

We observed a changing pattern of bicycle-related injuries in children, with the focus changing from head trauma to thoracic and abdominal injuries, and a trend to increasingly severe injuries.

Objective

To assess the changing injury pattern, and investigate the development of preventive measures to improve safety.

Design, setting, and participants

Retrospective record review of 142 paediatric patients admitted to our Department of Paediatric Surgery between 1996 and 2005 following bicycle-related injuries. Clinical, laboratory, diagnostic, and therapeutic aspects were analysed. Additional information concerning children's bicycle-related injuries in Israel was obtained from the Gertner Institute (Israel National Center for Trauma and Emergency Medicine Research) and from Beterem (The National Center for Children's Safety & Health, the Safe Kids Israeli Chapter) National Report on Child Injuries in Israel 2006.

Main outcome measures

The nature and severity of injuries were reviewed, and two 5-year periods compared—from 1996 to 2000 (53 children—Group 1), and from 2001 to 2005 (89 children—Group 2).

Results

Head trauma was more common in the Group 1 patients (52.6% vs. 45.2%), but skull fractures and intracranial haemorrhage occurred more frequently in Group 2 (28.5% vs. 16.7%; 21.3% vs. 8.3%, respectively). Injury to the stomach or duodenum, kidneys and liver were all more common in Group 2. Splenic injury occurred with equal frequency in both groups, but more severe injuries were seen in Group 2. More children in Group 2 required intensive care (31% vs. 19.3%).

Conclusions

There is a changing pattern of bicycle-related injuries in children, with chest and abdominal injuries dominating, and an increasing incidence of more severe injury. These findings are important in decision-making regarding preventive measures.     

Determination of national pediatric injury prevention priorities using the Injury Prevention Priority Score

Purpose

Previous studies have found that the Injury Prevention Priority Score (IPPS) provides a reliable and valid method to gauge the relative importance of different injury causal mechanisms at individual trauma centers. This study examines its applicability to prioritizing injury mechanisms on a national level and within defined pediatric age groups.

Methods

A total of 47,158 patients (age <17) in the National Pediatric Trauma Registry were grouped into common injury mechanisms based on ICD-9 E-Codes. Patients also were stratified by age group. IPPS was calculated for each mechanism and within each age group.

Results

Falls of all types account for the greatest number of injuries (n = 15,042; 32%), whereas child abuse results in the most severe injuries (mean Injury Severity Score, 13.3) However, the most significant mechanisms of injury, according to IPPS, were motor vehicle crashes followed by pedestrian struck by motor vehicles. Certain age groups had specific injury problems including child abuse in infants and assault and gun injuries in adolescents.

Conclusions

IPPS provides an objective, quantitative method for determining injury prevention priorities based on both frequency and severity at the national level. It also is sensitive to age-related changes in different mechanisms of injury.     

Epidemiology of foot injury in a high-income developing country

Objectives

To study the epidemiology of foot injuries and factors predicting their severity in a high-income developing country so as to define prevention priorities.

Patients and Methods

All patients admitted to Al-Ain Hospital with foot injury between March 2003 and March 2006 were identified from a prospectively collected Trauma Registry. Injuries were scored using foot and ankle severity scale (FASS). Bilateral, multiple or segmental injuries, open fractures or those with FASS score higher than 3 were included in severe foot injury group and compared with simple foot injury group regarding patients’ demography, co-morbidities, trauma mechanism and energy, incident location, number of associated injuries, Injury Severity Score (ISS) and hospital stay using a univariate analysis. A logistic regression model was then used to study factors predicting severity of foot injury.

Results

171 patients (156 males) were studied. The average (range) age was 34 (2-75). 95 had right foot injury, 66 had left, and 10 had both. Fall from height was the most common mechanism. 105 (61%) had work-related injuries. 130 (76%) had isolated foot injury. 151 (88%) had 212 foot fractures. 20 (12%) had soft tissue injuries. 70 (41%) had severe injuries while 101 (59%) had simple ones. The multiple logistic model was highly significant (p = 0.002). Number of associated injuries (p = 0.025) and location of trauma (p = 0.044) were significant while the amount of energy (p = 0.054) showed a strong trend to predict severity.

Conclusions

Fall from height is the most common mechanism of foot injury in United Arab Emirates. The number of associated injuries, high-energy trauma, and being work related are predictors of foot injury severity. Prevention priorities include counteractions against falling from height and falling heavy objects as occupational hazards.     

Injury patterns among obese children involved in motor vehicle collisions

Purpose

The purpose of this study was to compare injury patterns among obese children to their nonobese counterparts involved in motor vehicle collisions.

Methods

A nationwide data collection program containing occupant, collision, and injury details from police-reported tow-away crashes between 1997 and 2006 were used. Risk ratios (RRs) and associated 95% confidence intervals (CIs) were adjusted for age, sex, restraint, seat track position, vehicle curb weight, and total velocity change.

Results

An estimated 9 million children aged 2 to 17 years (20.2% obese) were involved in motor vehicle collisions during the study period. Among 2-to-5-year-olds, obesity increased the risk of severe head (RR, 3.67; 95% CI, 1.03-13.08) and thoracic (2.27; 1.01-5.08) injuries. Among 6-to-9-year-olds, obesity increased risk of thoracic (2.31; 1.08-4.95) and lower extremity (LE) injuries (1.89; 1.03-3.47). Among 10-to-13-year-olds, obesity increased the risk of severe thoracic (1.98; 1.08-3.65) and LE (6.06; 2.23-16.44) injuries. Among 14-to-17-year-olds, obesity increased risk of severe LE injuries (1.44; 1.04-2.00) but decreased risk of abdominal (0.20; 0.07-0.60) and head (0.33; 0.18-0.60) injuries, very similar to the pattern reported in obese adults.

Conclusion

The pattern of obesity-associated injuries changes from a higher risk of head and thoracic injuries among young children to a pattern in late teenagers that is similar to obese adults.     

Epidemiology of acute head injuries in Canadian children and youth soccer players

Background

Limited studies have been done to assess head injury characteristics for children and youth soccer players in Canada.

Objectives

To describe acute head injury characteristics in children and youth soccer players and identify the characteristics of patients who required hospital admission.

Methods

Analysis was based on the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP). Soccer-related head injuries amongst 5-19 year old children presenting at 16 hospital emergency departments during 1994-2004 were selected in the study. All head injury-related variables (nature of injury, mechanism of injury, location of play, soccer type and season of play) were stratified by age and sex. A logistic regression model, consisting of the injury-related variables, sex and age as the independent variables, was performed to examine the characteristics of those head-injured patients who required hospital admission.

Results

Overall, there were 4720 head injury cases identified (15% of all soccer-related emergency department visits). The highest proportion of head injuries was amongst males (70%) and children aged 10-14 years (50%). Of head injury cases, 35% were superficial and/or open wounds, 28% minor head injuries, 11% concussions, 9% eye injuries and 5% fractures. The total number of cases that required hospital admission was 164 (3.5%). Based on logistic regression analysis, head-injured youth aged 15-19 years were almost two times more likely to be admitted to hospital than their younger counterparts (OR = 2.2, 95% CI: 1.3-3.6). Compared to ball contact injuries, contact with structures/surfaces, other players/persons and other unspecified objects increased the odds of hospital admission at least by two-folds. Moreover, those who played unorganised soccer were significantly more likely to be admitted to the hospital as compared to those who played organised soccer (OR = 1.7, 95% CI: 1.2-2.6). Finally, playing in the non-winter seasons had increased likelihood of hospital admissions.

Conclusions

Head injuries constituted a significant proportion of soccer-related injuries presenting to emergency departments. Future studies need to evaluate the nature and safety of the playing surfaces/turf and other structures on or around the field of play.     

The diagnosis of acute urethral trauma

Background

During trauma resuscitation, blind catheterization of an injured urethra may aggravate the injury by disrupting a partially torn urethra. In busy trauma centers, retrograde urethrograms (RUG) prior to catheterisation for all patients with unstable pelvic fractures presents a challenge during trauma resuscitation, and the procedure is not commonly practiced despite Advanced Trauma Life Support (ATLS) and World Health Organisation recommendations. The aim of this study was to determine the presenting clinical features of patients with urethral injuries and to predict major trauma patients needing further investigation to exclude this injury.

Methods

A retrospective review of adult major trauma patients diagnosed with urethral injuries during an 8-year period at a major trauma centre, was conducted.

Results

There were 998 major trauma patients with fractures of the pelvis over the study period, of whom 223 had pubic symphysis disruption. There were 29 patients with urethral injuries. The sensitivity of any one of the traditional signs of urethral trauma was 66.7% (95% CI: 46.0-82.8). After exclusion of patients with penetrating trauma and iatrogenic injuries, pubic symphysis disruption on initial pelvis AP X-ray and/or the clinical signs of urethral injury had a sensitivity of 100% (95% CI: 84.4-100.0) for urethral trauma.

Discussion

Reliance on clinical features alone to predict urethral injury results in a substantial proportion of missed injuries in major trauma patients. RUGs did not appear to be needed in patients with no disruption of the pubic symphysis on initial pelvis X-ray or where no signs of urethral injury are present. In the absence of clinical signs and pubic symphysis disruption, blind urethral catheterisation may be attempted.     

Staircase falls: High-risk groups and injury characteristics in 464 patients

Introduction

Few data are available about the epidemiology and injury characteristics in staircase falls. The available literature mainly concerns children and autopsy studies.

Objective

To describe the epidemiology and injury characteristics of staircase falls, and to identify high-risk groups for these falls.

Methods

All patients who reported to an academic Accident & Emergency (A&E) department in 2005 after a staircase fall were selected in the Dutch Injury Surveillance System These data were linked to the hospital Trauma Registry database.

Results

Four hundred and sixty-four patients (42% male, p = 0.001), with a median age of 35 years were included. Children under five suffered significantly more head injuries. Male patients showed significantly more thoracic injuries than female patients. Spinal column fractures were only seen in patients over 25 years of age. Older patients tended to accumulate more rib fractures and lower extremity fractures and were admitted more frequently than the younger patients. Sixty-one patients (13%) required admission. Two patients, both with severe traumatic brain injury (TBI), died. National data on staircase falls were comparable with our hospital data. However, in comparison to the national population data, senior citizens in this study had an incidence that was markedly higher than in the younger patients.

Conclusion

Injuries due to staircase falls occur in all age groups, however, children under five years are relatively over-represented with higher rates of head injury. Senior citizens showed a markedly higher incidence than younger patients. Most injuries occur to the distal extremities and are relatively mild.     

Risk factors for blunt thoracic aortic injury in children

Background/Purpose

Because blunt thoracic aortic injury is rare in children, a high index of suspicion is needed to identify this injury. The purpose of this study was to use a large national trauma database to define the risk factors for blunt thoracic aortic injury in children.

Methods

Using the National Trauma Database, the authors compared patient demographics, mechanism of injury, and associated injuries between children sustaining blunt trauma with and without a thoracic aortic injury. Factors independently associated with this injury were identified using multivariate methods.

Results

Among 26,940 children with a blunt mechanism of injury, 34 (0.1%) children sustained a thoracic aortic injury, 14 (41%) of whom died. Thoracic aortic injuries were independently associated with age, injury sustained as an occupant in a motor vehicle crash, and severe injuries (Abbreviated Injury Scale value of ≥3) involving the head, thorax (other than aorta), abdomen, and lower extremities.

Conclusions

Older children involved in a motor vehicle crash with severe head, torso, and lower extremity injuries are a group at high risk for injury to the thoracic aorta. These easily identifiable risk factors may facilitate more rapid identification of this rare and potentially fatal injury.     

Ocular injury requiring hospitalisation in the South East of Ireland: 2001-2007

Aim

To investigate whether recent socio-demographic changes and recent health and safety measures have impacted on the trends of ocular trauma in the South East of Ireland.

Methods

We retrospectively reviewed all cases of ocular trauma admitted to our department between October 2001 and September 2007, and the following data were retrieved: demographic details; mechanism of injury and nature of injury.

Results

During the study period, 517 patients were admitted with ocular trauma. Work-related and home-related activities were the commonest causes of admission, and accounted for 160 (31.8%) and 145 (28.4%) cases, respectively. In 2006/2007, and following the influx of migrant workers from the 10 new EU accession states (EUAS), the incidence of hospitalised ocular injuries per 100,000 was 89 in persons from the EUAS versus 18 in those of Irish origin, P ≤ 0.0001. After adding the offence of not wearing a seat belt to the traffic penalty point system in Ireland, the proportion of road traffic accident (RTA)-related ocular injuries dropped significantly from 6.7% to 2.4%, P = 0.03.

Conclusion

The inclusion of the offence of not wearing a seat belt in the traffic penalty point system may have contributed to the significantly lower proportion of hospitalised ocular injuries attributable to RTAs. Also, the demographic profile of patients admitted because of ocular trauma has changed over the last 6 years, reflected in an increasing proportion of these injuries in persons from the EUAS. These data will inform healthcare providers, and those involved in developing health and safety guidelines for the workplace.     

Incidence and significance of injuries to the foot and ankle in polytrauma patients—An analysis of the Trauma Registry of DGU

Background

Injuries to the foot and ankle are often missed or underestimated during the initial care for polytraumatized patients. Nonetheless, injuries to the lower extremity exert significant influence on long-term outcome after discharge from the acute care facility. Since the mortality of trauma decreased in the last decades, these injuries gain more effect on the overall outcome. We analysed foot and ankle injury patterns, associated procedures and special characteristics of this population during early care.

Methods

Multiply injured patients of the Trauma Registry of DGU (TR-DGU; Injury Severity Score, ISS ≥ 16) with injuries to the foot and ankle (group F&A) were compared to the remaining TR-DGU population (group Non-F&A) for differences in injury characteristics, surgical treatment and early outcome. A detailed comparative statistic is provided.

Results

Demographic data and injury severity were comparable between the groups. The group F&A showed significantly more falls from a height above 3 m and suicidal injuries. Their overall injury severity to the extremities, especially to the regions different from the foot and ankle, was significantly higher compared to group Non-F&A. Group F&A patients had more surgeries and less intensive care complications. Mortality was 11.6% (F&A) and 16.2% (Non-F&A). Concerning initial outcome when discharged from the acute care facility, group F&A patients more commonly were moderately or severely disabled in everyday life.

Conclusions

Our data enhance the need for a meticulous search for injuries to the foot and ankle in patients with falls, comparably light injuries to the trunk and head and especially in patients with multiple and severe injuries to the skeletal system. Since 88.4% of patients with foot and ankle injuries are discharged alive, early appropriate care should be given to these injuries that significantly affect long-term outcome.     

Severe tyre blast injuries during servicing

Background

The destructive potential of the tyre explosions has received little attention in the medical literature. Fatal and severely deforming injuries have been reported. These blasts mainly affect the personnel servicing big vehicle tyres such as trucks and buses. We aimed to review the relevant literature on tyre blast injuries so as to define the mechanism of injury, outcome, and its methods of prevention.

Methods

A search of the English literature on tyre blast injuries was performed through Medline. Different studies were retrieved, analysed and combined together.

Results

A total of 763 patients were studied in the literature. Most of the patients were young aged male mechanics and the explosions usually occur during tyre servicing especially during inflation. Injury is caused by the pressure impact of the explosion or by direct hit of the rim. The head and face are the most commonly affected regions (48%) followed by the upper limbs (20%). About 25% of patients had multi-trauma. The overall mortality is high (19%) and is mainly caused by head injuries.

Conclusion

Inflated large tyres contain a tremendous amount of potential energy. Tyre blast injuries during servicing have a high morbidity and mortality. Preventive occupational methods should be implemented.     

The outcome of displaced intra-articular calcaneal fractures that involve the calcaneocuboid joint

Introduction

The outcome of displaced intra-articular fractures of the calcaneus is affected by many factors such as fracture type and age. The restoration and maintenance of the posterior facet is a priority and has a strong correlation with improved outcome. The fracture occasionally extends anteriorly to the calcaneocuboid joint (CCJ). Currently there is little literature discussing pain, functional or radiographic information about calcaneal fractures, which involve the CCJ or those that do not. The aim of this study was to compare pain and functional outcome measurements in a cohort of calcaneal fractures treated operatively and non-operatively to determine whether CCJ involvement was important.

Patients and methods

A prospective database of calcaneal fractures managed by a single surgeon was reviewed. CT images allowed us to assess the degree of CCJ involvement before and after surgery. Final outcome was determined by pain (validated visual analogue score) and functional outcomes (SF-36) taken 2 years after injury with further CT imaging used to determine the presence of arthritic change at the CCJ. 59 patients with 64 intra-articular calcaneal fractures were identified who also had 35 fractures that extended to the CCJ. Pre-operative CT imaging identified 3 levels of CCJ involvement: Undisplaced fracture line (n = 27); fractures that involved <50% of the CCJ (n = 4) and fractures that involved >50% of the CCJ with joint subluxation (n = 4).

Results

Pain and functional scores were comparable between fractures that involved the CCJ and those that did not. All fractures that involved >50% of the CCJ demonstrated arthritic change 2-years after injury.

Discussion

Displaced intra-articular fractures of the calcaneus will often have a fracture line extending into the CCJ. This is commonly undisplaced and does not appear to predict continued pain, dysfunction on radiographic appearance using generalised outcome measurements.
