Salvage of a failed valgus osteotomy for nonunion of an unstable pertrochanteric fracture is reported. A valgus intertrochanteric osteotomy is performed for a failed sliding hip screw fixation of an unstable pertrochanteric fracture at another institution. Four months following osteotomy, the fracture was still un-united with two distal screws of the hip plate broken and a coxa vara deformity. ...

PURPOSE The most common life-threatening complication of pelvic trauma is bleeding. Arterial bleedings frequently require active management, preferably with transcatheter arterial embolization (TAE). Hemodynamic instability and/or contrast extravasation at computer tomography (CT) examination are reliable indicators of arterial injury. Unstable pelvic fractures are much more hemorrhagic than st...

According to AO/ASIF classi!cation system the pelvic ring fractures are graded into three types, A, B, and C, in order of increasing severity (4). Type A injuries are stable including avulsion fractures, fractures of the iliac wing and transverse fractures of the sacrum. Type B injuries are rotationally unstable but vertically and posteriorly stable. "ey may be caused by external rotatory force...

OBJECTIVES Healing in cancellous metaphyseal bone might be different from midshaft fracture healing due to different access to mesenchymal stem cells, and because metaphyseal bone often heals without a cartilaginous phase. Inflammation plays an important role in the healing of a shaft fracture, but if metaphyseal injury is different, it is important to clarify if the role of inflammation is als...

BACKGROUND An unstable distal clavicle fracture (Neer type II) is an indication that surgical intervention is required. Numerous treatment options have been introduced, but there is no gold standard. METHODS We report on our experience of 29 consecutive cases, between 2002 and 2008, of acute unstable distal clavicle fracture (Neer type II) and operative treatment using transacromial pins with...

Introduction Chance fractures, the horizontal splitting vertebral fractures caused by flexion distraction mechanism, are inherently unstable fractures. These fractures can land up with significant visceral injuries. There are most commonly seen at thoracolumbar junction or in lumbar spine due to their high mobility. These fractures are extremely rare in the thoracic spine due to the rigidity of...

conclusions negative pressure inspiration is significantly impaired by an unstable chest wall. restoring mechanical stability of the fractured ribs improves respiratory outcomes similar to baseline values. results a wide variation in the mean inspiratory volumes and peak flows were measured between specimens; however, the effect of a flail chest wall and the subsequent internal fixation of the ...

BACKGROUND This study was performed to evaluate functional and radiological results of pelvic ring fractures treatment by open reduction and internal fixation. METHODS Thirty eight patients with unstable pelvic fractures, treated from 2002 to 2008 were retrospectively reviewed. The mean patients' age was 37 years (range 20 to 67). Twenty six patients were men (4 patients with type B and 22 pa...

BACKGROUND The purpose of this study was to evaluate the role of medial support and clinical factors responsible on outcomes and major complications associated with treatment of unstable proximal humerus fractures using a locking plate and suture augmentation. METHODS Sixty-three cases in 62 patients (42 female, 20 male) were evaluated between September 2004 and October 2008. Cases were divid...

OBJECTIVE This is a retrospective review of 13 unstable Hangman's fractures who underwent posterior C2-3 fixation to describe clinical outcomes with a literature review. METHODS Thirteen patients for unstable Hangman's fracture were enrolled between July 2007 and June 2010 were included in this study. The medical records of all patients were reviewed. Concurrently, clinical outcomes were eval...
