BACKGROUND The dynamic compression screw is a plate and screws implant used to treat fractures of the distal femur. The Biomet Matthews Nail is a new retrograde intramedullary nail designed as an alternative surgical option to treat these fractures.

Varus osteotomy of the distal femur is recommended for osteoarthritis of the knee with significant valgus deformity, but the operation is difficult to plan and perform. A simple technique involving a jig referenced to the line of the tibia is described. This allows accurate overcorrection by a few degrees, with impaction and secure fixation at the osteotomy. It has been successful, with no comp...
A controlled study, comparing computer- and conventional jig-assisted total knee replacement in six cadavers is presented. In order to provide a quantitative assessment of the alignment of the replacements, a CT-based technique which measures seven parameters of alignment has been devised and used. In this a multi-slice CT machine scanned in 2.5 mm slices from the acetabular roof to the dome of...
