双反牵引器辅助复位治疗股骨远端Müller A型骨折

目的：探讨应用顺势双反牵引器辅助复位小切口内固定治疗股骨远端MüllerA型骨折的疗效。方法 ：自2018年1月至2019年12月应用顺势双反牵引器辅助复位，微创小切口锁定钢板内固定治疗的股骨远端MüllerA型骨折患者22例，男14例，女8例；年龄29～58(41.23±7.03)岁。受伤至手术时间1～7(3.41±1.71) d。按Müller分型：A1型4例，A2型10例，A3型8例。术后膝关节功能采用Schatzker-Lambert股骨远端骨折标准评价。结果：术后切口均Ⅰ期愈合，无感染、骨髓炎等并发症，骨折均愈合，无畸形愈合及骨不连发生。22例患者获随访，时间12～18(14.50±2.02)个月。术后愈合时间3～6(4.64±1.14)个月。根据Schatzker-Lambert股骨远端骨折标准评定：优12例，良6例，中4例。结论：应用顺势双反牵引器辅助复位微创小切口锁定钢板内固定是治疗股骨远端Müller A型骨折较理想方法。

Treatmen of distal femoral fracture of Müller type A with homeopathic bidirectional-traction reduction device unite with internal fixation

Objective To investigate the effect of treatment of M ü ller A fracture of distal femur with small incision internal fixation assisted by homeopathic bidirectional-traction reduction device. Methods From January 2018 to December 2019, 22 patients (14 males and 8 females) with Müller type A distal femoral fractures were treated with homeopathic bidirectional-traction assisted reduction and minimally invasive small incision locking plate internal fixation;The age ranged from 29 to 58 years old with an average of (41.23±7.03) years. The time from injury to operation was 1 to 7 days with an average of (3.41±1.71) days. According to Müller classification,there were 4 cases of type A1,10 cases of type A2,and 8 cases of type A3. The postoperative knee joint function was evaluated by Schatzker Lambert fracture criterion of distal femur. Results All the incisions healed in one stage without infection,osteomyelitis and other complications. All the fractures healed without malunion and nonunion. All of 22 patients were followed up for 12 to 18 months with an average of (14.50±2.02) months. The healing time was 3 to 6 months with an average of (4.64±1.14) months. According to Schatzker Lambert criteria for distal femoral fracture,12 cases were excellent,6 good,and 4 medium. Conclusion It is an ideal method to treat Müller type A fracture of distal femur with homeopathic bidirectional-traction assisted reduction device and minimally invasive small incision locking plate internal fixation.
