This report describes a safe reproducible approach to effectively manage these locally aggressive lesions with good short-term results. The Musculoskeletal Tumor Society score improved significantly from a pre-operative median of 23.5 (range: 16–28) to a post-operative median of 29 (range: 26–30) ( P = 0.005). However, all patients had their hips preserved with good function at the latest follow-up, and no serious complications recorded. We had a single case (10%) of recurrence at the trochanters for which re-curettage was done. The lesion extended into the neck in 60% of patients with the physis being either closed in seven or closing in three patients. These were six males and four females, with a mean age of 17 ± 2.7 years (range: 14–20) and a mean follow-up of 34 ± 12 months (range: 17–57). Ten patients were managed using surgical hip dislocation with direct access to femoral head lesions, extended curettage through a modified trapdoor approach, and cement reconstruction. We are presenting our results with surgical hip dislocation approach with the aim to evaluate its efficacy in preventing recurrence and its safety, preserving a functional hip joint and avoiding complications. Anatomical limitations may lead to increased risk of local recurrence, damage to the articular cartilage, growth disturbances, and/or avascular necrosis (AVN). Femoral head chondroblastoma poses a surgical challenge.
