一位十六歲病患因左髖部疼痛及跛行六個月被診斷為缺血性壞死。放射性檢查顯示左股骨頭缺血性壞死及囊泡形成，核磁共振掃描顯示左股骨頭塌陷，診斷為第三期股骨頭缺血性壞死。在放射線引導下，我們為此病患進行左股骨頭減壓及人工骨植入手術，術後限制病人負重活動及使用柺杖三個月。病人每個月回門診追蹤病人，於六個月後恢復日常活動。放射性檢查顯示左股骨頭缺血性壞死區域產生新骨，核磁共振掃描顯示左股骨頭壞死區域水腫減少及有血管增生，沒有發現進一步的股骨頭塌陷。

A 16-year-old female patient suffering from left hip pain and limping for 6 months was diagnosed with avascular necrosis of the left hip. An x-ray revealed left femoral head avascular necrosis (AVN) with cystic formation. A magnetic resonance image (MRI) showed femoral head collapse. Stage III AVN was the diagnosis. After admission, core decompression combined with a bone graft (Allomatrix) was performed under fluoroscopy. The postoperative care of this patient included restricted weight bearing and use of crutches for 3 months. She received monthly outpatient department follow-up. Her daily activities and ambulation were almost back to normal after 6 months. An x-ray revealed new bone formation over the superior region of the femoral head at 6 months of follow-up. An MRI showed less edema, increased vascularity throughout the previously necrotic region, and no further subchondral bone collapse.
