摘要/Abstract

摘要： 目的:分析分体式髌骨爪联合空心螺钉内固定治疗髌骨粉碎性骨折的临床疗效。方法:l髌骨粉碎性骨折病人29例，均采用分体式髌骨爪联合空心螺钉内固定治疗，并分析骨折愈合、并发症、关节功能等指标。结果:29例病人均获得6～17个月的随访，平均10个月；按照改良Bostman髌骨骨折临床疗效标准评估疗效：优21例，良7例，差1例，优良率96.9%；所有病人均骨折骨性愈合，均未出现内固定物松脱、断裂、异物排斥反应等并发症。结论:分体式髌骨爪联合空心螺钉内固定治疗髌骨粉碎性骨折符合生物力学内固定原则，可将骨折解剖复位并恢复髌骨关节面的平整，手术操作简单、固定牢固、并发症少。

Abstract: Objective:To investigate the clinical effect of patella concentrator combined with hollow screw in the treatment of comminuted patellar fracture.Methods:29 cases with comminuted patellar fracture that treated with patella concentrator combined with hollow screw were retrospective analyzed.Fracture healing time，surgical complications and joint function recovery were observed.Results:A total of 29 patients had regular followup from 6 to 17 months（10 months on average），the cases showed excellent，good and poor were 21，7 and 1，respectively.The rate of fineness was 96.9% based on modified Bostman evaluation.The fractures were healed in all the cases without loosening，breakage and reject reaction of internal fixation.Conclusion:Treatment for comminuted patellar fracture using patella concentrator combined with hollow screw should be in accordance with the biomechanical principle，and achieved with anatomical reduction and recovery of joint surface，which is a good and simple method for the treatment of comminuted patellar fracture with stable fixation and fewer complications.

Key words: comminuted patellar fracture, patella concentrator, hollow screw, internal fixation
