Introduction
Closed reduction and percutaneous pinning using Zifko nails offer the advantage of a minimal soft-tissue dissection but have been criticised for limited stability and secondary fracture dislocation. Angular stable plate osteosynthesis enables anatomic reduction, but carries the risk of soft-tissue traumatisation and consecutive humeral head necrosis. The present study compares the clinical and radiological outcome of patients with dislocated two-part fractures of the proximal humerus, who were treated with either Zifko nails or angular stable plate fixation.Material and methods
A matched-pair analysis was performed and patient groups were matched according to age (±3 years), sex and fracture type. As many as 11 pairs of patients with a minimum follow-up of 3 years were formed and investigated radiographically and clinically using the Constant score (CS) and the visual analogue scale (VAS) for the patients’ satisfaction.Results
At the time of follow-up, the absolute CS was 83 points in the PHP group and 78 points in the Zifko group (n.s.). Neither in the age and gender-corrected CS was found a significant difference between the study groups (PHP 104 ± 29, Zifko 95 ± 17, n.s.) nor in terms of subjective patient satisfaction (PHP 6.54; Zifko 7.8, n.s.). The complication rate was also comparable in both groups.Conclusion
In conclusion, Zifko nailing represents a cost-effective minimally invasive surgical method with a complication rate and clinical outcome comparable to that after angular stable osteosynthesis by angular stable plate fixation in the treatment of two-part fractures of the proximal humerus. 相似文献2.
Objective
This study aims to evaluate the costs and health outcome for surgical and conservative treatment of displaced proximal humeral fractures.Design
This study is a randomised controlled trial.Participants
This study included 50 patients aged 60 or older admitted to hospital with a severely displaced three- or four-part fracture.Interventions
The patients were treated surgically with an angular stable interlocking implant (25 patients) or conservative treatment (25 patients).Main outcome measure
The outcomes measured included quality-adjusted life years (QALYs) and societal costs.Results
At 12 months’ follow-up, the mean difference in the number of QALYs was 0.027 (95% confidence interval (CI) = −0.025, 0.078) while the mean difference in total health-care costs was €597 in favour of surgery (95% CI = −5291, 3777).Conclusion
There was no significant difference in QALYs or costs between surgical and conservative treatment of severe displaced proximal humeral fractures. 相似文献3.

Objective
The objective of this study was to compare treatment results and complication rates between lateral and posterior approaches in surgical treatment of extra-articular distal humeral shaft fractures.Material and methods
Between June 2008 and May 2012, a total of 68 patients with extra-articular distal humeral shaft fractures were treated by lateral and posterior approaches. Of the patients, 30 were operated by a lateral approach (group I) and 26 patients were operated by a posterior approach (group II). There was no statistical significance between the two groups in sex distribution, age, the mechanism of the injury, injured arms, AO/ASIF (Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation) classification, and the time from injury to surgery (P > 0.05). Operation time, intraoperative bleeding volume, hospitalisation, clinical outcomes, and complications were compared between the two groups. The elbow functional results were evaluated by the Mayo Elbow Performance Score (MEPS).Results
All patients were followed up. The average of follow-up in group I was 15.53 ± 2.636 months (range, 12–22 months), and was 16.12 ± 2.889 months (range, 12–22 months) in group II. There was no significant difference in the operation time, intraoperative bleeding time, and hospitalisation between the two groups (P > 0.05). In group I, the mean time of bone union was 12.87 ± 1.852 weeks (range, 10–16 weeks), the mean degrees of elbow flexion was 139.20° ± 3.274° (range, 134–146°), the mean degrees of elbow extension was 4.77° ± 1.906° (range, 0–8°), and the mean points of MEPS was 87.00 ± 7.724 (range, 70–100 points). In group II, the mean time of bone union was 12.96 ± 2.218 weeks (range, 10–16 weeks), the mean degrees of elbow flexion was 137.85° ± 4.076° (range, 130–145°), the mean degrees of elbow extension was 5.15° ± 2.327° (range, 0–9°), and the mean points of MEPS was 86.15 ± 7.656 (range, 70–100 points). There was no significant difference in the bone union, range of elbow flexion, range of elbow extension and MEPS between the two groups (P > 0.05). The overall complication rate in group I was lower than that in group II (P = 0.041).Conclusions
Both lateral and posterior surgical approaches acquired satisfied treatment results in the management of extra-articular distal humeral shaft fractures, and there was a lower complication rate using the lateral approach. 相似文献4.
Background and purpose
The purpose of this retrospective study was to examine the association between shortening of the clavicle after a united midshaft fracture and clinical outcome. Second, the purpose was to compare the results obtained by conservative treatment with either a figure-of-eight bandage or a simple sling.Materials and methods
This study included 136 patients with a united, conservatively treated, midshaft clavicle fracture. Mean age was 35 years (range 15-70 years); mean follow-up time was 55 months (range 24-83 months). The shortening of the clavicle was measured on a radiograph including one antero-posterior view of both clavicles on a single film and defined as the difference between the injured and the contralateral clavicle. The clinical outcome was measured using the Constant-Murley Score.Results
The mean difference in the Constant-Murley Score between the injured and the contralateral shoulder was 7.3, P < 0.001 (95% confidence interval (CI) 5.6; 9.1). Mean shortening of the injured shoulder was 11.6 mm, P < 0.001 (95% CI 10.2; 13.0). A shortening of more than 20 mm was not associated with a poorer clinical outcome. The results obtained by conservative treatment with either a figure-of-eight bandage or a simple sling showed no difference in shortening or in the Constant-Murley Score.Conclusions
We found that conservative treatment of midshaft clavicle fractures resulted in final shortening and mild reduction of shoulder function. A shortening of 20 mm or more was not associated with a poorer clinical outcome. The figure-of-eight bandage and a simple sling were equal treatments of midshaft clavicle fractures. 相似文献5.
Purpose
Early definitive stabilisation is usually the treatment of choice for major fractures in polytrauma patients. Modifications may be made when patients are in critical condition, or when associated injuries dictate the timing of surgery. The current study investigates whether the timing of fracture treatment is different in different trauma systems.Materials and methods
Consecutive patients treated a Level I trauma centre were documented (Group US) and a matched-pair group was gathered from the German Trauma Registry (Group GTR). Inclusion criteria: New Injury Severity Score (NISS) > 16, >2 major fractures and >1 organ/soft tissue injury. The timing and type of surgery for major fractures was recorded, as were major complications.Results
114 patients were included, n = 57 Group US (35.1% F, 64.9% M, mean age: 44.1 yrs ± 16.49, mean NISS: 27.4 ± 8.65, mean ICU stay: 10 ± 7.49) and n = 57 Group GTR (36.8% F, 63.1% M, mean age: 41.2 yrs ± 15.35, mean NISS: 29.4 ± 6.88, mean ICU stay: 15.6 ± 18.25). 44 (57.1%) out of 77 fractures in Group US received primary definitive fracture fixation compared to 61 (65.5%) out of 93 fractures in Group GTR (n.s.). The average duration until definitive treatment was comparable in all major extremity fractures (pelvis: 5 days ± 2.8 Group US, 7.1 days ± 9.6 Group GTR (n.s.), femur: 7.9 days ± 8.3 Group US, 5.5 days ± 7.9 (n.s.), tibia: 6.2 days ± 5.6 Group US, 6.2 days ± 9.1 Group GTR (n.s.), humerus: 5 days ± 3.7 Group US, 6.6 days ± 6.1 Group GTR (n.s.), radius: 6 days ± 4.7 Group US, 6.1 days ± 8.7 Group GTR (n.s.).Conclusion
The current matched-pair analysis demonstrates that the timing of initial definitive fixation of major fractures is comparable between the US and Europe. Certain fractures are stabilised internally in a staged fashion regardless the trauma system, thus discounting previous apparent contradictions. 相似文献6.
Aim
To assess whether disruption of the posterior cortex of intracapsular femoral fractures leads to an increased incidence of complications following closed reduction and internal fixation by multiple cannulated screws in young adults.Methods
A total of 146 consecutive adult patients with 146 femoral neck fractures were treated by closed reduction and internal fixation with parallel cannulated screw in inverted triangle or diamond configurations. All enrolled patients were divided into three groups: those with a non-displaced femoral neck fracture (Garden types I or II), those with a displaced femoral neck fracture (Garden types III or IV) but no posterior cortex disruption and those with a displaced femoral neck fracture (Garden types III or IV) and a disrupted posterior cortex.Results
Based on an average follow-up of 4.76 years (range, 2-6 years), displaced femoral neck fractures with a disrupted posterior cortex demonstrated an increased risk for avascular necrosis of the femoral head, shortening, redisplacement and conversion of prosthetic replacement as compared with those fractures without posterior cortex disruption (p = 0.002, 0.016, 0.001 and <0.0001, respectively).Conclusions
As compared with a femoral neck fracture with an intact posterior cortex, a displaced femoral neck fracture with a disrupted posterior cortex increases the risk for avascular necrosis, redisplacement and shortening and raises the likelihood that prosthetic replacement will be needed. Orthopaedic surgeons should be aware of this prognostic factor. 相似文献7.
Purpose
To review one surgeon's experience with a novel type of “hybrid” locking plate (which has both 3.5 mm and 4.5 mm locking holes) for difficult fractures of the meta-diaphyseal humeral shaft.Methods
Over a 2-year period, 24 patients who presented with a metaphyseal humeral fracture or nonunion (proximal or distal) were treated surgically by a single surgeon. A “hybrid” locking plate containing 3.5 mm locking holes on one end and 4.5 mm locking holes on the other end (Metaphyseal plate, Synthes, Paoli, Pa) was used in all patients. The selection of this implant was based on fracture location and bone quality. Fractures were operated on through an anterolateral or direct posterior approach. All fractures were secured with a minimum of three 4.5 mm screws on one side of the fracture and three 3.5 mm screws on the other side. All patients were treated with a similar post-operative protocol for early range of shoulder and elbow motion.Results
Three patients were lost to follow-up. The cohort consisted of 15 women and 6 men with a mean age of 49 years (range 18-78). There were 14 acute fractures and 7 nonunions. Twelve fractures involved the distal metaphyseal segment and 9 involved the proximal metaphyseal segment. Twenty-two patients completed a minimum 6-month clinical and radiographic follow-up and form the basis for this report. All 21 patients healed their fractures or nonunions at a mean of 4.5 months. There were no infections or hardware failures. In every case the “hybrid” nature of the plate design was felt to be advantageous.Conclusion
This “second generation” metaphyseal locking plate, which affords the surgeon the ability to place a greater number of smaller calibre screws within a short bone segment, while using traditional large fragment screw fixation in the longer segment, is clearly an improvement in plate design. Meta-diaphyseal upper extremity long bones may serve as the most ideal location for this implant. 相似文献8.

Introduction
The currently accepted treatment for displaced supracondylar humeral fractures in children is closed reduction and fixation with percutaneous Kirschner wires. The purpose of this study was to retrospectively review a novel cross-wiring technique where the cross-wire configuration is achieved solely from the lateral side, thereby reducing the risk of ulnar nerve injury.Methods
We retrospectively reviewed all children who had undergone this procedure at our centre over a 10-year period. The primary end points were a major loss of reduction as determined by radiological alignment and iatrogenic ulnar nerve injury. Secondary end points included clinical alignment, elbow range of motion and complications.Results
A total of 43 patients, who underwent lateral cross-wiring for displaced supracondylar fractures (Gartland type II and type III) of the humerus were reviewed with a mean follow-up time of 36 months. No major loss of reduction occurred. The mean change in Baumann's angle (4.2 ± 1.6°) between intra-operative and follow-up radiographs was not significant (p > 0.05). No iatrogenic case of ulnar nerve injury occurred. The ‘carrying angle’ and ‘return to function’ in all children had returned to normal relative to the other side. Postoperative complications consisted of three patients developing pin-site infections, which were successfully treated.Conclusion
Dorgan's lateral cross-wiring technique is an effective option in treating displaced supracondylar fractures of the humerus in children. It is as effective as the traditional cross-wire technique in terms of fracture healing with a reduced risk of ulnar nerve injury. 相似文献9.
Purpose
The aim of this study is to examine the demographic factors, functional outcome and radiological data to predict the outcome of humeral diaphyseal fractures.Methods
We performed a prospective study on a consecutive series of 110 patients of 16 years or over, who had sustained a humeral diaphyseal fracture. There were 42 males and 68 females, with an average age of 59 years (range 16-93 years). A total of 72% sustained low-energy injuries, and 89 patients (81%) were primarily treated non-operatively.Shoulder function was assessed using the Neer's and Constant's scores at 8 weeks, 3 months, 6 months and 1 year after injury. Muscle strength was determined isokinetically using a Biodex System 2 dynamometer. Non-union was defined as a failure to bridge at least three cortices and persistence of tenderness or mobility at the fracture site 16 weeks after fracture.Results
Sixteen patients (17%) had non-union at 16 weeks, while 80 had achieved union and a further 14 were lost to follow-up. After stepwise multiple linear regression was performed to isolate independent factors affecting outcome, only the presence of a proximal diaphyseal fracture was found to predict non-union along with a poor Neer's score at 8 and 12 weeks. Poor Neer's scores could be predicted at 26 weeks by age (P < 0.05), previous stroke (P < 0.001) and non-union (P < 0.001). At 52 weeks both age (P < 0.01) and previous stroke (P < 0.01) were independently predictive of poorer Neer's scores. Malunion of any degree had no detectable effect on function.Conclusions
Our results indicate that non-union of humeral diaphyseal fractures can be predicted in the presence of a proximal third fracture with a Neer's score of less than 45 by 12 weeks after fracture. Early surgery improves early function, but this is not a lasting effect. Poor shoulder function is predicted by increasing age, proximal third fractures and non-union. We recommend that surgery to promote union be considered at 12 weeks after fracture in fit patients with fractures of the proximal third of the humerus, poor Neer's scores and no radiographic progression to union. 相似文献10.
Purpose
Technique for the fixation of two, three, and four part proximal humerus fractures has rapidly shifted towards the use of specially contoured proximal humerus locking plates. The purpose of this study is to evaluate the short to medium term functional results and common complications associated with the fixation of proximal humerus fractures with locking plates.Methods
The PubMed and EMBASE databases were used to perform a systematic review of the English literature to assess the functional results and complications associated with proximal humerus locking plates. Our inclusion criteria were proximal humerus fracture due to trauma (excluding pathologic fractures), patients greater than 18 years of age, more than 15 patients in the study or subgroup of interest, at least 18 months follow-up, at least one relevant functional outcome score, and quality outcome score of at least 5/10. Studies that did not meet these criteria were excluded. All institutional, author, and journal information was concealed to minimize reviewer bias.Results
Twelve studies including 514 patients met the inclusion criteria. At most recent follow-up patients achieved a mean Constant score of 74 and a mean DASH score of 27. The overall rate of complications was 49% including varus malunion, 33% excluding varus malunion, and reoperation rate was 14%. The most common complications included varus malunion 16%, AVN 10%, screw perforation of the humeral head into the joint 8%, subacromial impingement 6%, and infection 4%.Discussion
Fixation of proximal humerus fractures with proximal humerus locking plates is associated with a high rate of complications and reoperation. Further study is needed to determine what technical errors and patient characteristics are risk factors for failure of this now common fixation technique. 相似文献11.
Aim
In order to assess the effect of osteoporosis on healing time, the files of 165 patients with femoral shaft fractures that were treated in our institution with locked-reamed intramedullary nailing were retrospectively reviewed.Patients and methods
Patients with open fractures, pathological fractures, revision surgery, severe brain injuries and prolonged ITU stay were excluded. In all patients the Singh-index score for osteoporosis and the canal bone ratio (CBR) were assigned. Sixty-six patients fulfilled the inclusion criteria. Patients were divided into two groups; group A (29 patients) consisted of patients over 65 years old with radiological evidence of osteoporosis and group B (37 patients) of patients between 18 and 40 years old with no signs of osteoporosis.Results
In all group A patients Singh score ≤4 and CBR > 0.50 were assigned, suggesting the presence of osteoporosis, whereas all group B patients were assigned with Singh score ≥5 and CBR < 0.48. Fractures of group A healed in 19.38 ± 5.9 weeks (12-30) and in group B 16.19 ± 5.07 weeks (10-28), P = 0.02.Conclusions
Fracture healing of nailed femoral diaphyseal fractures is significantly delayed in older osteoporotic patients. Further studies are required to clarify the exact impact of osteoporosis in the whole healing process. 相似文献12.

Aim
To establish whether posterior multifragmentation of intracapsular proximal femoral fractures leads to an increased incidence of non-union and avascular necrosis following internal fixation by contemporary methods.Methods
After preoperative radiography which was evaluated for posterior fragmentation, 1042 intracapsular hip fractures (471 undisplaced and 571 displaced) were treated with reduction and internal fixation. The rates of non-union and avascular necrosis in the presence or absence of fragmentation were compared in both undisplaced and displaced groups.Results
The undisplaced cases comprised 460 non-fragmented and 11 fragmented fractures. The complication rates were 14% and 18%, respectively. Displaced fractures consisted of 489 non-fragmented and 82 fragmented cases. In this group, complication rates were 43% and 40%, respectively. No difference was statistically significant.Conclusions
Using current methods of internal fixation of intracapsular hip fractures, there is no significant association between the posterior multifragmentation of the femoral neck observed on preoperative radiography and the later development of fracture healing complications. 相似文献13.

Objectives
We report early results using a second generation locking plate, non-contact bridging plate (NCB PH®, Zimmer Inc. Warsaw, IN, USA), for the treatment of proximal humeral fractures. The NCB PH® combines conventional plating technique with polyaxial screw placement and angular stability.Design
Prospective case series.Setting
A single level-1 trauma center.Patients
A total of 50 patients with proximal humeral fractures were treated from May 2004 to December 2005.Intervention
Surgery was performed in open technique in all cases.Main outcome measures
Implant-related complications, clinical parameters (duration of surgery, range of motion, Constant–Murley Score, subjective patient satisfaction, complications) and radiographic evaluation [union, implant loosening, implant-related complications and avascular necrosis (AVN) of the humeral head] at 6, 12 and 24 weeks.Results
All fractures available to follow-up (48 of 50) went to union within the follow-up period of 6 months. One patient was lost to follow-up, one patient died of a cause unrelated to the trauma, four patients developed AVN with cutout, one patient had implant loosening, three patients experienced cutout and one patient had an axillary nerve lesion (onset unknown). The average age- and gender-related Constant Score (n = 35) was 76.Conclusions
The NCB PH® combines conventional plating technique with polyaxial screw placement and angular stability. Although the complication rate was 19%, with a reoperation rate of 12%, the early results show that the NCB PH® is a safe implant for the treatment of proximal humeral fractures.15.
Objective
To evaluate and analyse the geometrical discrepancies between the proximal femur and two types of AO/Association for the Study of Internal Fixation (AO/ASIF) Proximal Femoral Nail Anterotation (PFNA/PFNA-II) using computed tomography (CT)-based analysis in Asian patients, and its implication in lateral cortical impingement during reduction intra-operatively in subtrochanteric fractures.Materials and methods
Coronal CT images of hips in 50 randomly selected healthy cases were analysed using a unique measurement method with respect to the height, diameter, bending angle and inclination angle of lateral cortex of proximal femur. The data were then compared with dimensions of PFNA and PFNA-II.Results
The average height of proximal femur was 61.1 ± 5.2 mm, diameter 18.1 ± 1.5 mm, bending angle 8.4 ± 2.2° and inclination angle of lateral cortex 11.9 ± 1.1°. The average impingement length of the lateral cortex was 54.2 ± 4.7 mm (range 41.4-64.2 mm), which was shorter than the height of the proximal femur. On comparison with dimensions of PFNA and PFNA-II, the lateral inclination angle and impingement length were found to be discrepant in PFNA; however, in the latter the flat lateral surface helps avoiding impingement with the lateral femoral cortex.Conclusion
Our study provides clear evidence that the flat lateral shape of PFNA-II is better suited for the femur of Asian patients by reducing the chances of impingement with the lateral proximal femoral cortex during intra-operative reduction in subtrochanteric fractures. 相似文献16.
Objective
Distal radial fractures are common. Modern trends favour operative treatment in many instances, providing stable fixation and early functional recovery. Recent biomechanical evidence suggests that volar locking plates (VLPs) enable adequate stability for dorsally displaced fractures, both in dorsally intact (DI) and in dorsally comminuted (DC) fractures. The aim of the study was to compare the clinical outcome of these two fracture groups treated with a VLP.Methods
Retrospective case-control analysis of 91 distal radial fractures treated surgically using VLP by a single surgeon between the years 2006 and 2008 was carried out. Fractures were classified according to the Arbeitsgemeinschaft für Osteosynthes/Orthopaedic Trauma Association (AO/OTA) classification. Based on initial pre-reduction X-rays and computed tomography (CT) scans, fractures were classified into two groups of DI and DC fractures. The patients were re-evaluated at 2 and 6 weeks, 3 and 6 months and 1 year.Results
Forty-one fractures (45%) were dorsally comminuted. Patients in the DC group were significantly older (mean 59 vs. 46 years, p < 0.01) and included more female patients, as well as significantly more C3 type fractures than the DI group (p < 0.04). The mean Disabilities of the Arm, Shoulder and Hand (DASH) score at 1 year postoperatively was 6.3 ± 2.3 for the DC group, as compared with 6.6 ± 2.02 for the DI group (p = 0.64). Average time to return to work was longer in the DC group (81.2 vs. 63.6 days, p = 0.05). Range of motion, volar tilt, and radial inclination were within clinically acceptable values and did not differ significantly among the two groups.Conclusions
VLP fixation of DC distal radial fractures results in the maintenance of reduction and comparable functional and radiographical outcome with respect to DI fractures. 相似文献17.

Background
Radial nerve palsy associated with humeral shaft fractures is the most common nerve lesion complicating fractures of long bones. The purpose of the study was to review the outcome of surgical management in patients with low energy and high energy radial nerve palsy after humeral shaft fractures.Methods
Eighteen patients were treated operatively for a humeral shaft fracture with radial nerve palsy. The mean age was 32.2 years and the mean follow up time was 66.1 months (range: 30-104). The surgical management included fracture fixation with early nerve exploration and repair if needed. The patients were divided in two groups based on the energy of trauma (low vs. high trauma energy). The prevalence of injured and unrecovered nerves and time to nerve recovery were analysed.Results
Five patients sustained low and 13 high energy trauma. All patients with low energy trauma had an intact (4) or entrapped (1) radial nerve and recovered completely. Full nerve recovery was also achieved in five of 13 patients with high energy trauma where the nerve was found intact or entrapped. Signs of initial recovery were present in a mean of 3.2 weeks (range: 1-8) for the low energy group and 12 weeks (range: 3-23) for the high energy group (p = 0.036). In these patients, the average time to full recovery was 14 and 26 weeks for the low and high energy trauma group respectively. Eight patients with high energy trauma had severely damaged nerves and failed to recover, although microsurgical nerve reconstruction was performed in 4 cases. Patients with high energy trauma had a prolonged fracture healing time (18.7 weeks on average) compared to those with low energy fractures (10.4 weeks), (p = 0.003).Conclusions
The outcome of the radial nerve palsy following humeral fractures is associated to the initial trauma. Palsies that are part of a low energy fracture uniformly recover and therefore primary surgical exploration seems unnecessary. In high energy fractures, neurotmesis or severe contusion must be expected. In this case nerve recovery is unfavourable and the patients should be informed of the poor prognosis and the need of tendon transfers. 相似文献18.
Objective
To determine the incidence of rotational malalignment in distal femoral and proximal tibial fractures using computed tomography (CT) scanograms following indirect reduction and internal fixation with the minimally invasive percutaneous osteosynthesis (MIPO) technique.Design
Prospective Cohort.Setting
Level I Trauma Centre.Patients/Participants
A total of 27 consecutive subjects, and 14 proximal tibia and distal femur fractures.Intervention
All patients underwent indirect reduction and internal fixation with a MIPO plating system. A CT scanogram to measure rotational malalignment between the injured and non-injured extremity was then undertaken.Main outcome measure(s)
Femoral anteversion angles and tibial rotation angles between the injured and non-injured extremities were compared. Malrotation was defined as a side-to-side difference of >10°.Results
A total of 14 postoperative tibias and 13 femurs underwent CT scanograms. Three females and 11 males with an average age of 38.1 years sustained proximal tibia fractures and six females and seven males with an average age of 55.8 years sustained distal femur fractures. The difference between tibial rotation in the injured and the non-injured limbs ranged from 2.7 to 40.0° with a mean difference of 16.2° (p = 0.656, paired T-test). Fifty percent of the tibias fixed with MIPO plates were malrotated >10° from the uninjured limbs. The difference between femoral anteversion in the injured and non-injured limbs ranged from 2.0 to 31.3° with a mean difference of 11.5° (p = 0.005, paired T-test). A total of 38.5% of the distal femurs fixed with MIPO plates were malrotated >10° from the uninjured limb.Conclusions
Following fixation of distal femoral and proximal tibial fractures, the incidence of malrotation was 38.5% and 50%, respectively. The difference of the mean measures was significant for femoral malrotation; however, statistical significance could not be demonstrated for tibial malrotation. The incidence of malrotation following MIPO plating in this study is much higher than that quoted in previous studies. 相似文献19.
Objectives
Research has shown that early surgical intervention for hip fractures serves to decrease mortality. In 2004 the Ministry of Health decided to condition the reimbursement regime at the time of operation. The objectives of this study were to examine whether the reform succeeded to decrease inpatient mortality of hip fracture casualties.Method
The study utilised data drawn from the Israeli Trauma Registry (ITR) for the years 1999-2006. The study population included patients aged 65 and older with an isolated diagnosis of hip fracture following trauma.Results
Two years after the reform, the inpatient mortality decreased by 34% amongst patients undergoing fixation surgery, and by 30% amongst all operated patients. Median LOS decreased by 2 days. The proportion of patients undergoing hip fracture fixation surgery within 48 h increased by 35%.Conclusions
The implementation of a payment limited by time for hip fracture fixation surgery increased the number of patients being operated within 48 h, shortened patient LOS, and decreased inpatient mortality. 相似文献20.
