儿童股骨干骨折常不采用髓内钉固定,原因为髓内钉固定可引起儿童骨生长停滞、股骨头缺血性坏死等并发症。目前对股骨头缺血性坏死尚无满意的治疗方法,故视其为严重并发症。髓内钉固定儿童股骨干骨折引起股骨头缺血性坏死,可能为髓内钉穿经梨状窝时损伤旋股内侧动脉所致。为减少这一并发症,采用经股骨大转子尖部髓内钉固定儿童股骨干骨折。患儿平仰卧位,患肢行胫骨结节牵引,取股外侧切口,从股骨大转子尖端
Fractures of children often not used intramedullary nail fixation, because intramedullary nail fixation can cause bone growth arrest in children, femoral head necrosis and other complications. At present, there is no satisfactory treatment for avascular necrosis of the femoral head, so it is regarded as a serious complication. Intramedullary nail fixation of femoral shaft fractures of the femoral head caused by avascular necrosis may be intramedullary nail through the pear-shaped litter injury caused by the spinous process inside the artery. In order to reduce this complication, the femoral shaft of the femoral shaft was fixed by intramedullary nails of the great trochanter. Children with supine position, tibial tubercle traction limbs, take shares lateral incision, from the greater trochanter tip
