应用微型骨锚重建指伸肌腱终腱止点--附6例报告

目的 探讨微型骨锚在指伸肌腱终腱止点撕脱伤修复中的临床疗效。方法 对6例指伸肌腱终腱止点撕脱患指，先用克氏针将远侧指间关节固定于过伸位，然后将Mitek mcro微型骨锚植人远节指骨基底背侧指伸肌腱附着处，再用锚尾部的4-0 Ethibond缝合线与撕脱的指伸肌腱缝合，重建止点。结果 6例全部获得随访，术后随访3～6个月，平均4．1个月。按Dargan功能评定方法评定：优4例，良2例。术后X线片未见骨锚松动、脱落。结论 微型骨锚用于修复与重建指伸肌腱终腱，操作简便，易掌握，疗效可靠。

Application of Mitek mini bone anchors in reconstruction of terminal extensor tendon insertions

Objective To evaluate the treatment outcome of reconstruction of terminal extensor tendon insertions by using Mitek mini anchors. Methods 6 cases of extensor terminal tendon avulsion were involved. The distal interphalangeal (DIP) joint was stabilized in slightly over-extension position with a Kirschner wire. The Mitek mini anchor was placed into the base of the distal phalanx and its two 4-0 Ethibond sutures were woven into the terminal extensor tendon to reconstruct the insertion. The K wire was removed in 4 weeks when movement of the DIP joint started. Results All cases were followed for 3 to 6 months with an average of 4.1 months. According to Dargan scales, the result was excellent in 4 cases and good in 2 cases. Follow-up x-ray films showed that all 6 of implants remained securely anchored in the bone. Conclusion Reconstruction of extensor terminal tendon insertion by Mitek mini anchor is technically easy. The result is reliable.
