Abstract
OBJECTIVE
Investigate the effect of distal nail diameter on proximal femoral shortening (PFS) after cephalomedullary nailing of hip fractures.
METHODS
A retrospective cohort study of 80 patients aged 50 years and older with pertrochanteric hip fractures treated with a 10 or 11 mm short cephalomedullary nail (CMN) was performed. We measured abductor lever arm shortening, femoral height shortening, and PFS.
RESULTS
There was no difference in abductor lever arm shortening (p = 0.09), femoral height shortening (p = 0.86), and PFS (p = 0.34) between the 10 and 11 mm groups.
CONCLUSIONS
Our results suggest that distal nail diameter does not affect PFS.
LEVEL OF EVIDENCE
III.
摘要
目的
研究髋部骨折行髓内钉固定术后，远端钉直径对股骨近端缩短（PFS）的影响。
方法
对80例年龄50岁及以上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10或11毫米短髓内钉（CMN）治疗。我们测量了外展肌杠杆臂缩短、股骨高度缩短和PFS。
结果
10毫米组和11毫米组在外展肌杠杆臂缩短（p = 0.09）、股骨高度缩短（p = 0.86）和PFS（p = 0.34）方面没有差异。
结论
我们的结果表明，远端钉直径不影响PFS。
证据级别
III级。
