Three femoral head chondroblastomas (one associated with aneurysmal bone cyst) were excised, using a technique of percutaneous extraarticular curettage. Whereas a standard approach to the femoral head lesion requires hip arthrotomy plus a cortical window in the femoral head or neck, the extraarticular technique enters the tumor cavity via a tunnel drilled from the lateral femoral cortex through the medullary canal of the femoral neck. The videoarthroscope assists with visualization during curettage of the cartilage tumor. Bone graft material may be packed into the tumor cavity without fear of subsequent leakage into the joint space. At an average follow-up of 25 months, all three femoral head tumors have healed without recurrence and with no complications related to the approach. The extraarticular endoscopic approach could be used to treat selected benign femoral head or neck lesions other than chondroblastomas.
采用经皮关节外刮除技术切除了3例股骨头软骨母细胞瘤（其中1例合并骨囊肿）。标准的股骨头病变治疗方法需要进行髋关节切开术并在股骨头或颈部开一个皮质骨窗，而关节外技术是通过从股骨外侧皮质向股骨颈髓腔钻出的隧道进入肿瘤腔。在刮除软骨肿瘤时，关节镜辅助进行可视化操作。骨移植材料可填充到肿瘤腔内，而不用担心随后漏入关节腔。平均随访25个月，所有3例股骨头肿瘤均愈合，无复发，且无与手术方法相关的并发症。关节外内镜手术方法可用于治疗除软骨母细胞瘤以外的某些良性股骨头或颈部病变。
