Summary

This study compares the posterior approach to the anterolateral approach using the ReCap® Total Hip Resurfacing System.

Detailed description

Theoretical considerations of RECAP procedures through anterolateral trochanteric osteotomy: * Less bone resection, less complicated revision surgery. * Reduced stress shielding of the femur. * Lower incidence of hip dislocations. * Walking function improved by change in mobilisation regime and operative technique. * Risk of femoral neck fracture is reduced by preoperative measurement of bone density. * Risk of avascular necrosis of the femoral head is reduced with the anterolateral approach preserving femoral head blood supply and preventing later failure of the implant.

Conditions

• Arthritis
• Avascular Necrosis

Interventions

Type	Name	Description
PROCEDURE	Anterolateral approach	The anterolateral approach is performed with the patient positioned on the side. The blood supply to the femoral neck from the medial circumflex artery is regarded preserved by this surgical method.
PROCEDURE	Posterior approach	The posterior approach is performed with the patient positioned on the side. The medial circumflex artery is cut at the lower border of the short external rotators risking a compromised blood supply to the femoral head.
DEVICE	ReCap Total Hip Resurfacing	This arm utilizes the anterolateral approach using the ReCap® Total Hip Resurfacing System.
