摘要
目的:通过对比髓内钉和锁定钢板对股骨远端骨折治疗的临床效果,研究两种治疗方法促进骨膜骨痂形成的差异。方法:回顾性分析156例股骨远端骨折患者,分别筛取12例逆行髓内钉治疗患者与12例锁定钢板治疗患者做配对研究。使用特定软件测量对比两组患者伤后12周X线片股骨侧面和前后面骨痂形成量。结果:相应骨折愈合部位髓内钉组的平均骨痂形成面积为(233±280)mm2是锁定钢板组(95±109)mm2的2.4倍,两组比较,差异有统计学意义(P=0.028)。结论:股骨远端骨折后锁定钢板治疗组骨痂形成少于髓内钉治疗组。
Objective： Through comparison of clinical effect in distal femur fractures stabilized with locking plates and intramedullary nails to test the difference of callus formation between intramedullary nails and locking plates.Methods： 156 distal femur fractures were reviewed to extract cases treated individually with retrograde IM nails（n=12）,and treated with locking plates（n=12）.Periosteal callus was measured on lateral and antero-posterior radiographs taken at 12 weeks after injury using validated software to objectively extract the size of peripheral callus from digital radiographs.Results： The nail group had 2.4 times more callus area per location（233±280 mm2） than the plate group（95±109 mm2,P=0.028）.Conclusion： Significantly less periosteal callus formed in fractures stabilized with locking plates than with IM nails.
