A precise radiologic technique for assessing the forces producing pelvic disruption has been helpful in arriving at a logical classification of injury. The examination should include anteroposterior, inlet and outlet views, as well tomograms occasionally computed-assisted tomographic evaluation (CT scanning). On basis this assessment with some biomechanical studies, three major injury is suggested. anteroposterior lateral compression types, while vastly different, may both have stable...

Objective We sought to evaluate the use of a bioabsorbable, tobramycin-impregnated bone graft substitute (calcium sulfate alpha-hemihydrate pellets) in treatment patients with infected bony defects and nonunions. Study Design/Methods Twenty-five (15 male 10 female, mean age 43 years (range 27–69 years) requiring surgical debridement culture-positive long infection (16 associated nonunion) were entered into an ongoing consecutive, prospective clinical trial. Involved bones included tibia...

1. Thirty-seven cases of fracture the dens have been studied. 2. The incidence non-union was high: 64 per cent after apparently adequate closed treatment. 3. Possible causes high studied : attention is drawn to effect displacement and that posterior in particular. 4. Non-union with potential instability at atlanto-axial joint not acceptable a patient who expects lead normal active life. 5. Atlanto-axial fusion method choice treatment ; once has secured, pseudarthrosis no longer significant.

Background: A variety of methods are available for the fixation femoral shaft fractures after total hip arthroplasty. However, few studies in literature have quantified performance such repair constructs. The aim this study was to evaluate biomechanically four different constructs periprosthetic following Methods: Twenty synthetic femora were tested axial compression, lateral bending, and torsion determine initial stiffness, as well stiffness a simulated midshaft fracture with without bone...

Thoracolumbar burst fractures are a major cause of disability; however, there few studies on the functional outcome patients with this injury. The purpose study is to evaluate thoracolumbar using generic and condition-specific health status survey. SF-36 survey (generic) Roland scale (condition-specific) were administered 24 who had minimum 2 years follow-up after fracture without neurologic deficit. average score was 65% (compared 45% for dialysis 66% diabetes) 58% low back pain).

Despite modern fracture management techniques allowing for near anatomic reduction of acetabular fractures, there continues to be a risk posttraumatic arthritis and need total hip arthroplasty (THA). Few well-controlled studies have compared THA after fractures with THAs performed other indications in terms survivorship or complications, none, our knowledge, present 10-year data this setting.(1) How does the survival compare between those patients who underwent an primary avascular necrosis...

Pelvic fractures with disruption of the important weight-bearing sacroiliac area can lead to impaired gait due malunion or pelvic obliquity, back buttock pain arising from joint, and permanent neurologic damage. In eight patients joint dislocation, an anterior retrofascial approach stapling was performed. Six these maintained anatomic reduction their results were rated as excellent. Two had a slight loss because intermittent mild having fair results. another patients, plate fixation done....

Twenty-two were treated traction 108 by surgical operation. Stable in skin did well extensively appeared be best 90-90 skeletal traction. In fractures, it was determined that these patterns stable strong nail-plate device will provide adequate fixation. The may converted or lag screw fixation then fixed...

Abstract Background A variety of techniques are available for fixation femoral shaft fractures following total hip arthroplasty. The optimal surgical repair method still remains a point controversy in the literature. However, few studies have quantified performance such constructs. This study biomechanically examined 3 different screw-plate and cable-plate systems periprosthetic near tip Methods Twelve pairs human cadaveric femurs were utilized. Each left femur was prepared cemented...

All of the current modalities have a place in treatment diaphyseal humeral fractures. Functional bracing renders high rate union and seems to be safe method for most closed Type II III open fractures seem respond best plate fixation or external fixation, particularly when there are associated neural vascular pathologic findings. Patients with polytrauma who unable walk also treated fixation. Plate is adequate alignment cannot obtained nonsurgical methods. Intramedullary nailing remains...

Forty-eight patients with supracondylar fractures of the humerus have been treated at St. Michael's Hospital in past 10 years. Forty-six 48 were surgically. A comparison was made between use standard AO (ASIF) plates a pre-contoured plate especially designed for distal humerus. The results this suggested that specifically provided superior fixation and better anatomic restoration Anatomic reduction, rigid fixation, early surgery provide best results.

Eleven adults who had a flail shoulder due to brachial plexus palsy arthrodesis of the using single ten-hole pelvic-reconstruction plate. Both glenohumeral and acromiohumeral joints were fused with in position 30 degrees abduction, flexion, internal rotation. No bone graft was used. The patients immobilized spica cast for six weeks postoperatively. At an average follow-up twenty-five months after operation, been maintained solid fusion occurred each shoulder. patient required removal plate...
