OBJECTIVES
Examine the timing of proximal femoral shortening (PFS) after cephalomedullary nailing of hip fractures.
METHODS
A retrospective cohort study of 21 patients ≥50 years old with pertrochanteric hip fractures treated with a short cephalomedullary nail (CMN) was performed. Abductor lever arm shortening, femoral height shortening, and PFS were measured.
RESULTS
Mean PFS at 10-21 days postoperatively was 5.54 mm, compared to 11.31 mm at final follow-up. The percentage of total PFS that occurred within 10-21 days postoperatively was 53.9%.
CONCLUSION
Approximately half of total PFS occurs within 1.5-3 weeks and is notable on radiographs by the first postoperative visit.
目的
研究髋部骨折行髓内钉固定后股骨近端缩短（PFS）的时间。
方法
对21例年龄≥50岁的转子间髋部骨折患者进行回顾性队列研究，这些患者接受了短髓内钉（CMN）治疗。测量外展肌杠杆臂缩短、股骨高度缩短和PFS。
结果
术后10 - 21天的平均PFS为5.54mm，而末次随访时为11.31mm。术后10 - 21天内发生的PFS占总PFS的百分比为53.9%。
结论
约一半的总PFS发生在1.5 - 3周内，术后首次复查时在X线片上即可明显显示。
