摘要：青壮年股骨颈骨折是高能量损伤的结果，在骨折线斜形或短螺旋形的基础上，常伴有股骨颈后侧皮质的粉碎。后侧皮质粉碎使骨折复位固定后很不稳定；破裂骨块的复位缺失，容易造成骨折延迟愈合、不愈合甚至股骨头缺血坏死。伴有后侧皮质粉碎的青壮年股骨颈骨折仍是临床治疗的难题，近年来在骨折复位技术和内固定器械方面取得了不少进展。本文对此做一综述。

Femoral neck fracture in young adults are the result of high-energy injury, the oblique fracture line or the short spiral often accompanied by the comminution of the posterior cortex. Posterior comminution is an important cause of unstable fixation. The comminution defects are easy to cause fracture delayed union, nonunion and avascular necrosis of femoral head. The femoral neck fractures with posterior comminution in young adults is still a clinical problem. Fracture reduction techniques and internal fixation devices have made a lot of progress in recent years.
