【摘要】 背景:以往治疗下胫腓联合分离伴腓骨骨折患者采用石膏或夹板等外固定及螺钉、骨栓及钢板螺钉等内固定术式,但存在固定不牢靠、对合不良等弊端。目的:通过采用自行研制的新型内固定器--下胫腓钩板固定器治疗下胫腓联合分离伴腓骨骨折患者的初步临床疗效,观察下胫腓钩板固定器的生物力学特征。设计:自身前后对照观察。对象:选者2001-10/2004-03扬州大学临床医学院附属医院骨科就诊的下胫腓联合分离伴腓骨骨折的患者23例,根据Lauge-Hansen分类,旋后外旋型11例,旋前外旋型7例,旋前外展型5例。其中双踝骨折14例,三踝骨折9例。方法:采用下胫腓钩板固定器治疗23例下胫腓联合分离伴腓骨骨折。术后常规摄X射线片。1周即可进行距小腿关节功能锻炼,2个月左右即可部分负重行走。功能测评根据改良Mazur标准进行评价(分为优,良,可,差)。主要观察指标:①胫腓联合分离伴腓骨骨折患者术后愈合时间及功能测评。②不良事件及副反应。结果:23例患者平均随访11个月,均进入结果分析。①患者胫腓联合分离伴腓骨骨折术后愈合时间及功能测评结果:骨折愈合的时间为12～18周;优16例,良5例,可2例。②不良事件及副反应:患者下胫腓间隙无分离,内、外踝与距骨之间的距离对称,术后内固定无松动、断裂现象。结论:应用下胫腓钩板固定器治疗胫腓联合分离伴腓骨骨折患者,术后无并发症,并能恢复距小腿关节(踝关节)功能,其内固定稳定,生物力学性能较好。更多还原

【Abstract】 BACKGROUND: Conventional means in treatment of distal tibiofibular syndesmosis disruption include plaster cast or splint immobilization as external fixation and internal fixation using screws, and bone bolts or plates however, some disadvantages such as unstable fixation and uncertain fixation exist. OBJECTIVE: To observe the primary clinical curative effect of newly self-developed fixation, Hook-plate fixation HPF, for distal tibiofibular syndesmosis disruption and its biochemical characteristics of HPF.DESIGN: Self-control observation.PARTICIPANTS: We recruited 23 patients with sustaining abruption of lower tibiofibular ligament union with fibular fracture who received treatment in the Department of Orthopedics, Affiliated Hospital of Yangzhou University Medical College, between October 2001 and March 2004. According to the Lauge-Hansen classification system, there were 11 cases of supination-lateral rotations, 7 cases of pronation-lateral rotations and 5 cases of pronation-abductions. Among them 14 had bimalleolar fractures and 9 had trimalleolar fractures.METHODS: HPF was used on the 23 patients with distal tibiofibular syndesmosis disruption. Radiographs were taken routinely. Talocrural joint function exercise was recommended at week 1 and partial weight bearing was allowed 2 months later. Functions were evaluated according to modified Mazur’s criteria excellent, good, fair and poor. MAIN OUTCOME MEASURES: ① Healing time and function evaluation after operation for distal tibiofibular syndesmosis disruption. ② Adverse events and side effectsRESULTS: Totally 23 patients entered the result analysis, with the mean of 11 months’ follow-up. ① Results of healing time and function evaluation in the patients after operation for distal tibiofibular syndesmosis disruption: The healing time of fracture ranged from 12 to 18 weeks: 16 cases were excellent, 5 good, and 2 fair. ② Adverse events and side effects: There was no separation of the tibiofibular space, the distance between medial malleolus or lateral malleolus and anklebone was symmetrical. There was no mobilization or rupture of the internal fixation after operation.CONCLUSION: HPF is applied in treating distal tibiofibular syndesmosis disruption. It causes no postoperative complications, and can recover the ankle joint function with stable internal fixation and good biomechanical features.更多还原
