Objective sound wave amplitude measurement generated by a tuning fork. An analysis of its use as a diagnostic tool in suspected femoral neck fractures.

Introduction: Hip injuries are becoming a more common problem as the elderly population increases and their management represents a significant proportion of health care costs. Diagnosis of a fracture based on clinical assessment and plain films is not always conclusive and further investigations for such occult fractures, such as magnetic resonance imaging (MRI), are sometimes required which are expensive and may be difficult to access. Disruption to the conduction of a sound wave travelling through a fractured bone is a concept that has been used to diagnose fractures.

Failure of closed reduction after dislocation of Austin Moore hemiarthroplasty: an analysis of risk factors a 6-year follow-up study.

The aim of this study was to determine the factors associated with failure of closed reduction of dislocated Austin Moore hemiarthroplasty for subcapital neck of femur fracture. There were 44 (1.8%) cases of dislocation for a 6-year period.

Outcome of open rotator cuff repair. An analysis of risk factors.

The aim of this study was to evaluate the long-term functional outcome of full thickness rotator cuff tears treated by open repair and acromioplasty and to determine various factors affecting the outcome. This is a prospective clinical study on 42 patients who underwent full thickness rotator-cuff repair by a single surgeon between 2000 and 2003. The mean follow-up was 26 months.

Predictors of excessive blood loss during operative treatment of hip fractures.

Objectives: To determine the total blood loss and transfusion needs during operative treatments of hip fracture, and identify predictors of excessive blood loss.

Method: A prospective study of 242 consecutive patients operated for hip fractures over a 6 month period. The main outcome measure of blood loss was assessed by blood volume in the drainage system and swab weight.
