Chondroblastoma of the femoral head: management and outcome.
Chondroblastoma of the femoral head presents particular problems in treatment because the tumour is surrounded by articular cartilage on one side and epiphyseal plate on the other. Ten patients underwent treatment for a chondroblastoma involving the proximal femoral capital epiphysis. The patients were aged between eight and 19 years and in four the epiphysis was not yet fused. Five had curettage via a drill hole created up the femoral neck, of whom two developed local recurrence. Five had a direct approach to the chondroblastoma through the femoral neck, and there were no local recurrences in this group. Both patients with local recurrence were under 14 years of age-one was cured by a direct approach through the neck of the femur and the other by lifting a trap door of articular cartilage. Apart from one patient with a temporary leg length discrepancy, there were no other complications. We conclude that a direct approach is likely to lead to the best outcome for this rare condition.
