Introduction:
Intra-articular osteoid osteoma (OO) of the hip often presents with atypical symptoms and may mimic femoroacetabular impingement, leading to delayed diagnosis.
Case Report:
A 15-year-old girl presented with 2 years of right groin pain and restricted hip motion. Imaging revealed an intra-articular OO at the femoral head-neck junction. Surgical hip dislocation allowed complete excision of the nidus and restoration of the femoral head-neck offset. At 2-year follow-up, the patient was pain free with a full range of motion and no signs of impingement.
Conclusion:
Surgical hip dislocation provides full access to the femoral head-neck junction and enables safe, complete resection of intra-articular OO in adolescents.
