Clinical validation of the Oswestry-Bristol Classification as part of a decision algorithm for trochlear dysplasia surgery.

Aims: The Oswestry-Bristol Classification (OBC) is an MRI-specific assessment tool to grade trochlear dysplasia. The aim of this study is to validate clinically the OBC by demonstrating its use in selecting treatments that are safe and effective.

Methods: The OBC and the patellotrochlear index were used as part of the Oswestry Patellotrochlear Algorithm (OPTA) to guide the surgical treatment of patients with patellar instability.

Revision total hip and knee replacement.

The number of primary and revision total joint arthroplasty procedures is increasing exponentially with time. It is anticipated that there will be a huge expected demand for revision knee surgery over the next 2 decades. Knee revisions alone are projected to increase by 601% between 2005 and 2030 in the United States.

Complex regional pain syndrome (type 1): a comparison of 2 diagnostic criteria methods.

Background: Complex regional pain syndrome (CRPS) is a common problem presenting to orthopedic surgeons or pain therapists, most frequently encountered after trauma or surgery to a limb. Because of a lack of a simple objective diagnostic test, diagnosis is reliant on clinical assessment. Prospective studies have repeatedly demonstrated a higher incidence than retrospective studies, an observation that has been challenged owing to the lack of uniformity of diagnostic criteria across specialties and workers researching the condition.

Tip-Apex Distance as a Predictor of Failure Following Cephalo-Medullary Fixation for Unstable Fractures of the Proximal Femur.

Current research has been unable to confirm that intramedullary fixation provides greater stability for unstable fracture configurations of the proximal femur than extra-medullary devices. We present a retrospective analysis of the outcome of proximal femoral fractures treated with the Proximal Femoral Nail (PFN, Synthes) with particular reference to implant position and adequacy of reduction. Between May 2002 and October 2004, 61 patients with low-energy unstable proximal femoral fractures underwent surgery at a mean 2.
