Cast immobilization in bayonet position versus reduction and pin fixation of overriding distal metaphyseal radius fractures in children under ten years of age: a case control study

PurposeCompletely displaced distal radius fractures in children have been traditionally reduced and immobilized with a cast or pin fixed. Cast immobilization leaving the fracture displaced in the bayonet position has been recently suggested as a non-invasive and effective treatment alternative. This is a pilot comparative study between reduction and no reduction.MethodsWe assessed subjective, functional and radiographic outcome after a minimum 2.5-year follow-up in 12 children under ten years of age who had sustained a completely displaced metaphyseal radius fracture, which had been immobilized leaving the fracture in an overriding position (shortening 3 mm to 9 mm). A total of 12 age-matched patients, whose similar fractures were reduced and pin fixed, were chosen for controls. ResultsAt follow-up none of the 24 patients had visible forearm deformity and the maximal angulation in radiographs was 5° Forearm and wrist movement was restored (< 10° of discrepancy) in all 24 patients. Grip strength ratio was normal in all but three surgically treated patients. All patients had returned to their previous activities. One operatively treated boy who was re-operated on reported of pain (visual analogue scale 2).ConclusionThe results of this study do not demonstrate the superiority of reduction and pin fixation over cast immobilization in the bayonet position of closed overriding distal metaphyseal radius fractures in children under ten years with normal neurovascular findings.Level of evidenceIII     

The Effect of Providing Audiovisual Surgical Information on Decisional Conflict in Patients Undergoing Plate Fixation for Distal Radius Fractures

BackgroudPatients experiencing acute trauma have limited time for their involvement in shared decision making, which may lead to decisional conflict. The purpose of this study was to evaluate whether providing audiovisual surgical information can reduce decisional conflict when deciding between surgical and nonsurgical treatment in patients with distal radius fractures (DRFs) and to evaluate factors that may affect decisional conflict.MethodsWe prospectively enrolled 50 consecutive patients who presented with acute DRFs and chose to undergo surgery, for which volar plate fixation was recommended. We randomized these patients into 2 groups. The test group was given a video clip of audiovisual surgical information in addition to regular information while the control group was only given regular information. The video clip consisted of the purpose, procedure, and effect of the surgery, precautions and complications after the operation, and other treatment options that could be performed if operation was not performed. At 2 weeks after the surgery, we evaluated patients'' decisional conflict using a decisional conflict scale (DCS). In addition, we evaluated factors that might affect decisional conflict, such as age, dominant hand, comorbidities, history of previous operations, perceived disability, and provision of the video clip.ResultsThe test group showed significantly lower DCS scores than the control group (19.6 vs. 32.1, p = 0.001). In multivariate analysis, younger age and provision of the video clip were associated with lower DCS scores.ConclusionsThis study has demonstrated that providing information through audiovisual media such as video clips could reduce decisional conflict in patients who chose to undergo plate fixation for DRFs. This study also suggests that older patients may need more careful doctor-patient communication as they have more decisional conflict than younger patients.     

Complete urethral injury in the penile fracture: a case report and literature review

Penile fracture is described as a traumatic rupture of the tunica albuginea caused by blunt injury to the erect penis. It usually occurs as a single rupture of the tunica albuginea in one of two corpora cavernosa; a rupture with urethral injury is an extremely rare condition. Although its diagnosis is usually clinical, ultrasound plays an important role in confirming diagnosis and identifying the site of the injury. Here, we presented a case of penile fracture with complete urethral injury. A 43-year-old male was admitted to the hospital because of trauma to the genital and dysuria following sexual intercourse. After admission, the patient was diagnosed with double penile fracture and complete urethral injury after the physical and B-ultrasound examinations. Emergency surgery to remove the hematoma and repair the urethra was performed. The patient recovered smoothly and was discharged on the third day after operation. After two months’ follow-up, the patient urinated smoothly and achieved an adequate erection without other complications. In this case, consistent with previous studies, emergency surgery for penile fracture is necessary and can preserve the urethral function and sexual function. In addition, there are two lesions in tunica albuginea in this case, so careful search for the penile shaft during the surgery is important to avoid the missed injuries. This report provides evidence of an uncommon and underreported clinical case.     

Cranial floor fracture: A growing orbital roof fracture with encephalocele – Case Report

Orbital roof fractures are among the rarest of craniofacial fractures. The mechanism of injury is typically a high-impact blunt force vector directly to the orbit or forehead. Most patients are males between 20 and 40 years old, involved in motor vehicle accidents. Although most orbital roof fractures are managed conservatively, there is a significant risk of ophthalmologic and neurologic complications. Detailed craniofacial examination and high-resolution CT imaging is necessary for diagnosis. A multidisciplinary team approach is required for these challenging fractures.

The epidemiology of fragility fractures: Is there a role for bone quality?

Fragility fractures, particularly those of the hip, vertebrae, and distal forearm, constitute a major public health problem. The two ultimate determinants of fracture are bone strength and propensity to trauma. Bone strength depends not only upon bone mass but also upon a variety of qualitative aspects of bone structure. These include its architecture, the amount of fatigue damage it has sustained, and changes in its bulk material properties, indices that are collectively subsumed into the term bone quality Fragility fractures show differences in their patterns of incidence by age, sex, ethnic group, geographic area, and season. Many of these differences are currently unexplained, and disorders of bone quality might contribute to them. There are two fracture sites at which evidence implicates bone quality more directly—the spine and proximal femur. Many vertebral compression fractures follow minimal trauma, and controlled studies suggest that vertebral microarchitecture contributes to fracture risk independently of vertebral bone mass. At the hip, observational studies have pointed to a role for disordered trabecular architecture, accumulation of microfractures (fatigue damage), and the accumulation of osteoid. The extent to which these phenomena act independently of bone mass, however, remains uncertain.Presented at the NIA Workshop on Aging and Bone Quality, September 3–4, 1992, Bethesda, Maryland     

骨折与无骨折史患者的定量超声检查比较

目的：用定量超声方法对有骨折史的骨质疏松症患者进行骨量检查,方法用CUBA Clinical型定量骨密度超声仪对393例被疑为骨质疏松的患者进行检测,并根据病史按有无骨折中进行分组。分析二组患者宽频超声衰减（BUA）、超声速率（VOS）、强度指数（SI）与骨折次数的关系。结果：伴有骨折史的骨质疏松症虱的BUA、VOS、SI值都要比无骨折史的患者明显降低（P＝0．000）。结论定量超声值与骨折的发生次数呈负相关,其测定值越低,骨折的发生次数越多;骨的质量下降是造成骨质疏松骨折的主要原因。     

Cranial burst fracture in infants: acute recognition and management

In the past, the diagnosis of growing skull fracture or diastatic fracture has included a subset of injuries better referred to as cranial burst fracture. Cranial burst fracture, typically associated with severe injury in infants less than 1 year of age, is a closed, widely diastatic skull fracture accompanied by acute cerebral extrusion outside the calvarium. We treated 11 such infants at the LeBonheur Children's Medical Center and 2 at the Children's National Medical Center from January 1986 through December 1994. Infants ranged in age from 1 to 17 months, with an average age of 5.7 months. All presented with marked scalp swelling and a Glasgow Coma Scale score of 10 or less. Twelve had a history consistent with severe injury (motor vehicle accident, 7, abuse 5). The cause of injury in one patient remains unproven. Surgery (reduction of herniated cerebral tissue, repair of large dural laceration, and cranioplasty) was usually performed within 10 days of injury, a time period long enough to assure hemodynamic stability and resolution of acute cerebral swelling, yet sufficiently brief to avoid the chronic changes (scarring, parasitization of scalp vessels by damaged cortex) associated with a growing skull fracture. Prompt repair of cranial burst fracture may prevent ongoing brain injury such as has been neuropathologically demonstrated in patients with growing skull fracture. Magnetic resonance imaging establishes the diagnosis of cranial burst fracture in equivocal cases, rendering unnecessary a waiting period to see if scalp swelling resolves. Our experience, together with information in the neuropathological and neurosurgicla literature, suggests that cranial burst fracture is associated with severe trauma, requires expeditious treatment, and has been underdiagnosed in the past, leading to growing skull fracture, a condition requiring more extensive surgery.

Eleven university-orthopaedic centers in eastern France co-operated to review 250 femoral fractures in relation to hip prothesis. This is the largest published review. The aims of this retrospective study were:

An unusual cause of depressed skull fracture: case report

BACKGROUND: Camel collision accidents are a common occurrence in Saudi Arabia, with a high rate of mortality and morbidity. Isolated injuries are rare because of the nature of impact sustained by the person. CASE DESCRIPTION: A 4-year-old child with an isolated depressed skull fracture resulting from a camel collision is described. The other occupants of the car were crushed to death. The child sustained only an impact to his head, causing a compound depressed skull fracture with localized cortical damage. CONCLUSIONS: Camel collision accidents are a common cause of mortality and morbidity in Saudi Arabia. Isolated skull injuries are rare and result from a localized impact. This is the first report of a compound depressed skull fracture from such an incident. The extent of the problem and efforts toward prevention are described.
