Abstract
We have resected 4 benign cystic femoral head tumours under intraosseous endoscopic control. The resections were completely extraarticular through a tunnel made in the femoral neck from the lateral cortex. The procedures were assessed endoscopically with the help of a standard arthroscope. With a minimum follow-up of 1 year (range 1-16 years), there were no recurrences. Mean age at time of surgery was 23 years (range 19-26 years). Only 1 (fibrous defect) needed prophylactic osteosynthesis with a dynamic hip screw. The lateral approach through a bone tunnel allows preservation of the joint. The creation of a wider tunnel (10-15 mm) avoids the need for an irrigation system, without debilitating the bone structure, and simplifies the surgical procedure.
