Failure strengths of concentric and eccentric implants for hamstring graft fixation.

The purpose of this study is to compare the initial failure strengths of various interference screw devices used for tibial fixation of hamstring grafts in anterior cruciate ligament reconstruction and the effect of concentric or eccentric screw position. Quadrupled tendon grafts were harvested from freshly killed sheep. The grafts were then prepared and fixed in the distal femur using various devices (Intrafix (DePuy Mitek Raynham, MA, USA), RCI screw (Smith and Nephew Acufex, Mansfield, MA, USA), Wedge screw (Stryker Endoscopy, San Jose, CA, USA) in concentric position and Wedge screw in eccentric position with an interlock pin).

Iliotibial band Z-lengthening for refractory trochanteric bursitis (greater trochanteric pain syndrome).

Background: Trochanteric bursitis or greater trochanter pain syndrome (GTPS) is a frequent cause of lateral hip pain. This article reports our experience with a new method of Z-lengthening of the iliotibial band for refractory GTPS.

Methods: Fifteen patients (17 hips) were diagnosed with GTPS unresponsive to conservative treatment including steroid injection.
