胫骨髁间棘撕脱骨折患者关节镜下带线锚钉治疗的临床研究

目的：探讨关节镜下带线锚钉治疗胫骨髁间棘撕脱骨折的手术方法和疗效。方法：回顾性分析本院2004年8月～2008年6月收治的采用关节镜下骨折复位,带线锚钉固定治疗新鲜胫骨髁间棘撕脱骨折27例临床资料,按照Meyers-Mckeever胫骨髁间棘骨折分型：Ⅱ型16例,Ⅲ型11例。结果：27例获随访,随访时间5～27个月,平均16.7个月。所有患者骨折全部愈合,膝关节无不稳症状,术后参照Lysholm评分95～100分,平均97.3分。结论：关节镜下带线锚钉治疗胫骨髁间棘撕脱骨折,手术创伤小,手术方法简便易行,固定牢固,避免固定物的取出,可允许患者早期行走及进行积极的康复训练。

The clinical study of avulsion fracture of tibial eminence treated by suture anchors under arthroscopy

Objective： To explore the surgical skill and the effectiveness of avulsion fracture of tibial eminence treated by suture anchors under arthroscopy. Methods： The clinical data of 27 patients with fresh avulsion fracture of tibial eminence （type II in 16 cases and type III in 11 cases） which were treated with reduction and internal fixation by suture anchors under arthroscopy were collected from Aug. 2004 to Jun. 2008 with a retrospective analysis. Results： 27 cases had been followed up for 5-27 months （average of 16.7 months）. The fractures were all healed without symptom of displacement and nonunion. No knee joint relaxation or extension-restriction was found. The Lysholm score ranged from 95 to 100 with a mean of 97.3 postoperatively. Conclusion： The reduction and internal fixation of avulsion fracture of tibial eminence treated by suture anchors under arthroscopy is a technique of minimal trauma, easy-to-use, reliable fixation and avoiding the fixation out, allowing patients to have early walking and rehabilitation training.
