采用Stryke锁骨钩钢板治疗锁骨远端骨折合并肩锁关节脱位25例分析

Analysis 25 cases of Stryke collar-bone hook nickelclad in treatment of acromioclavicular dislocation and distal collar bone fracture

目的观察应用stryke锁骨钩钢板对锁骨远端骨折合并肩锁关节脱位进行切开复位内固定手术的治疗效果。方法对25例急性锁骨远端骨折合并肩锁关节脱位的患者行手术治疗，术后随访6～27个月。结果采用Karlsson标准评定患者术后的功能：A级23例，B级2例。无锁骨下神经、血管损伤，术后无感染，内固定无松动及脱出，无骨折不愈合或畸形愈合等现象，X线片显示锁骨骨折全部愈合，肩锁关节无再脱位发生，2—3个月可行无痛自由活动。结论采用锁骨钩钢板术中不损伤肩锁关节面，能够避免继发性创伤骨关节炎，手术创伤小、固定牢固，能早期活动肩关节，是治疗锁骨远端骨折合并肩锁关节脱位行之有效的方法。

Objective To investigate the therapeutic efficacy of Stryke collar-bone hook niekelelad in management of aeromioelavieular dislocation and distal collar bone fracture. Methods 25 cases of collar-bone fracture with CRIF operation using collar-bone hook niekelclad were included. Patients were followed up for 6 - 27 months after operation. Results The patients＇ post-operative function were evaluated with Karlsson standard. 23 of 25 cases were categorized as grade A and the other 2 were grade B. There was no complication associated with injury of subclavian nerve or vessel, no infection, no loose and prolapse of internal fixation devices as well as fracture disunion or malunion. X-ray shows the lesions of collar-bone fracture recovered well without aeromioclavicular dislocation on X-ray image. All patients achieved painless free-running after 2 -3 months. Conclusion The application of collar-bone hook niekelclad could reduce the chance of prolapse in patients with aeromioclavicular dislocation and distal collar bone fracture. As the acromioclavieular facet was not involved or impaired, there is a great advantage in reduced complication such as traumatic arthritis compared to those who received Kirschner wire ect. This method is characterized by little wound, fixation firmly and early recovery of the joint, and is effective to cure distal collar bone fracture and ae- romioelavieular dislocation.
