目的回顾性分析空心双头加压螺钉在 Hoffa骨折中应用的临床效果。方法本院自2004至2013年间治疗的 Hoffa骨折患者共21例，其中男13例，女8例；车祸伤15例，高处坠落伤4例，砸伤2例；按Letenneur分型I型11例，Ⅱ型6例，Ⅲ型4例；闭合性骨折15例，开放性骨折6例；全部患者均采用空心双头加压螺钉进行骨折固定，术后及时进行康复功能锻炼。结论术后随访时间6个月至3年，平均21．5个月；随访结果为所有骨折均达到骨性愈合，术中术后无血管及神经损伤、术后没有出现伤口及关节腔感染、术后无螺钉松动及断裂等并发症发生；根据Letenneur评估系统进行术后功能评估，本组患者优良18例，可2例，差1例，优良率85．7％。结论空心双头加压螺钉固定治疗 Hoffa骨折具有手术创伤小、固定可靠、术后功能恢复好的优点，是一种疗效可靠的治疗方法。“,”[Objective] Hollow double compression screw fixation were retrospectively analyzed the clinical effect of treatment of Hoffa fractures .[Methods] From 2004 to 2013 ,a total of 21 Hoffa fracture patients were recruited .There were 13 males and 8 females .And the causes were traffic accident ( n=15) ,high fall‐ing ( n=4) and crush injury ( n=2) .According to the Letenneur scheme ,the types were Ⅰ( n=11) ,Ⅱ( n=6) and Ⅲ ( n =4) .And the fractures were closed ( n=15) and open ( n=6) .Double hollow compression screw was applied for fracture fixation .And postoperative rehabilitation exercise was implemented in a timely manner .[Results] The average follow‐up period was 21 .5 (6~36) months .During follow‐ups ,osseous heal‐ing was achieved without perioperative vascular or nerve injury ,wound infection ,screw loosening or rupture . Postoperative function assessments were based on Letenneur system .And the outcomes were excellent ( n =18) ,fair ( n =2) and poor ( n =1) .And the excellent rate was 85 .7% .[Conclusion]Hollow double com‐pression screw is efficacious for Hoffa fractures .And it offers the advantages of mini‐invasiveness ,reliable fix‐ation and quick recovery of postoperative functions .
