关节镜下Arthrex线十字交叉法治疗胫骨髁间棘撕脱骨折

Arthroscopic Fixation for Tibial Eminence Fracture in Non-absorbable Arthrex Sutures Passing Through

目的探讨关节镜下Arthrex线四股双线四骨道十字交叉法治疗胫骨髁间棘撕脱骨折的手术方法和疗效。方法对21例胫骨髁间棘骨折患者行关节镜下复位,利用前交叉韧带胫骨定位器在骨床或骨块上准确确定钻孔位置,Arthrex编织缝线四股双线十字交叉法横穿前交叉韧带基底并经骨床或骨块上的钻孔及骨隧道引出关节外打结、固定。结果 21例病例均得到随访,平均随访时间1年10个月,骨折愈合良好,未出现关节反复肿胀及交锁等机械症状,膝关节功能基本恢复至伤前运动水平,未出现其他并发症。结论关节镜下四股双线四骨道十字交叉法治疗胫骨髁间前棘骨折是一种安全、有效的术式。

Objective To evaluate the technique and clinical effects of the treatment of tibial intercondylar eminence fracture by the means of making two decussate lines and four strands of non-absorbable Arthrex sutures passing through four bone tunnels under arthroscopy. Methods Total 21 cases of tibial intercondylar eminence fractures were treated under arthroscopy.By the use of ACL-aimer,the bone tunnels of the tibial or bone block were produced accurately. With the arthroscopy,the avulsion fracture were fixed by making two lines and four strands of non-absorbable Arthrex sutures cross the basalpart of anterior cruciate ligament and pass through the bone tunnels of the tibial or bone block,pulling out the sutures through those tunnels and fix them outside the joint. Results All of the 21 patients were followed up（ mean 18 months）. Bone healing was satisfactory in all cases. There were no complications. Knee function was adequately restored to preinjury sportive level in all patients.Conclusion The means of making two decussate lines and four strands of non-absorbable Arthrex sutures passing through four bone tunnels under arthroscopy is safe and effective to treat the tibial intercondylar eminence fracture.
