Avascular necrosis (AVN) of the femoral head is a relatively uncommon complication following an extracapsular hip fracture. Although it can occur following fixation of unstable 3-part or 4-part intertrochanteric fractures with significant posteromedial and posterolateral comminution, it remains a rare complication. We present a case of AVN of the femoral head following fixation of a stable 2-part intertrochanteric fracture in spite of good healing at the hip fracture site. This is a rare but eminently treatable cause of persisting hip pain after hip fracture surgery, and primary or secondary care physicians should be aware of this possibility.
股骨头缺血性坏死（AVN）是囊外髋部骨折后一种相对不常见的并发症。尽管它可发生于不稳定的三部分或四部分股骨转子间骨折固定术后，伴有明显的后内侧和后外侧粉碎，但仍然是一种罕见的并发症。我们报告一例稳定的两部分股骨转子间骨折固定术后发生股骨头缺血性坏死的病例，尽管髋部骨折部位愈合良好。这是髋部骨折手术后持续髋部疼痛的一种罕见但完全可治疗的原因，基层或二级医疗保健医生应意识到这种可能性。
