滑膜切除带血管蒂髂骨移植治疗儿童股骨缺血头坏死

TREATMENT OF CHILDREN AVASCULAR NECROSIS OF FEMORAL HEAD BY SYNOVECTOMY AND VASCULARIZED ILIAC BONE GRAFT

报道8例儿童股骨头缺血坏死病人,采用滑膜切除,带旋股外侧血管束髂骨块移植于股骨头颈部,经6个月～12个月随访,症状明显改善,关节活动良好,头骺高度正常或接近正常。

From March. 1987 to March. 1989,we have treated 8cases of children with avascular necrosis of the femoral headby synovectomy of the hip and lateral circumflex femoralartery pedicled iliac bone graft to the femoral neck. Satisfac- tory therapeutic results were achived. The advantages of thisoperation are : 1. the microcirculation of the femoral headwas improved-by intraarticular decompression. 2. the venouspressure decreased by osteotomy at femoral head and neck.3. iliac bone graft can prevent femoral head collapse. 4. theblood supply of the femoral head was reestablished by vascu-larized iliac bone graft.
