Purpose Bipolar hemiarthroplasty (HA) is an option for the treatment of unstable intertrochanteric fracture in elderly patients. There is a raising concern regarding cable-grip related complications for the fixation of trochanteric fragments. Therefore, the aim of this study was to evaluate outcome of cementless HA with fixation for the trochanteric fragments using monofilament wires in unstabl...

initial cracks occur in high strength concrete sleepers for various reasons, such as shrinkage and wrong curing and long lifetime of over 50 years of sleepers. these cracks may lead to complete failure of the structure. in order to more accurately design the sleepers, fracture mechanics (not strength of materials) should be incorporated. in order to achieve this purpose, it is important to fore...

This study aims to evaluate the biomechanical mechanism of pelvic ring injury for the stability of pelvis using the finite element (FE) method. Complex pelvic fracture (i.e., anterior column with posterior hemitransverse lesion) combined with pelvic ramus fracture was used to evaluate the biomechanics stability of the pelvis. Three FE fracture models (i.e., Dynamic Anterior Plate-Screw System f...

Introduction: Suicidal jumper’s fracture (unstable sacral fracture) is characterized not only by multiple fractures including thoracolumbar fractures, but also major chest and abdominal injuries. Early stabilization of these fractures and early ambulation are required for the treatment and management of chest and abdominal injuries. We present 3 cases of suicidal jumper’s fracture with thoracol...

An unstable pelvic fracture may be life threatening and can be seen as ‘the killing’ fracture. Even if this is the only injury, it may be a serious problem. In the initial management of this type of fracture, the principles of advanced trauma life support (...

INTRODUCTION Percutaneous screw fixation is considered the best option in unstable pelvic fracture with severe soft tissue injury. However, fixation technique at the level of S3 has not been well established. This paper showed the feasible surgical technique of S3 screw insertion in unstable pelvic fracture with severe soft tissue injury. METHODS We reported 2 cases of unstable pelvic injury ...

The supination-external rotation or Weber B type fracture exists as a stable and an unstable type. The unstable type has a medial malleolus fracture or deltoid ligament lesion in addition to a fibular fracture. The consensus is the unstable type and best treated by open reduction and internal fixation. The diagnostic process for a medial ligament lesion has been well investigated but there is n...

BACKGROUND The objective of this study was to investigate the biomechanical effects of medial fracture gap augmentation in locked plating of an unstable 2-part proximal humeral fracture with calcar screws and insertion of a corticocancellous bone block. Furthermore the mechanical behavior of dynamic locking screws in the non-parallel arrangement of a proximal humeral plate was of interest. ME...

INTRODUCTION Humeral biepicondylar fracture dislocation is a very rare injury reported only once in English literature by G R Taylor et al. We report a case of humeral biepicondylar fracture dislocation in a 13-year-old girl with a unique mechanism of injury. CASE PRESENTATION A 13-year-old girl presented with trauma elbow. Radiographs showed biepicondylar fracture of humerus with dislocation...

OBJECTIVE To evaluate the effect the type of hip fracture (femoral neck or trochanteric) has on the Health-Related Quality of Life of elderly subjects. METHODS Forty-five patients with hip fractures (mean 74.30 +/- 7.12 years), 24 with a femoral neck fracture and 21 with a trochanteric fracture, completed the 36-item Short Form Health Survey (SF-36) at baseline and four months after fracture....
