新式缝合法重建指伸肌腱终腱止点的临床研究
Clinical studies of novel suture method for re-attaching terminal part of tendons of digital extensors
目的 介绍一种新式的指伸肌腱终腱止点重建方法。 方法 用直径1.0 mm克氏针固定远侧指骨间关节于平伸位,再用1.0 mm克氏针在末节指骨基底部偏背侧横行钻一骨隧道,利用3/0双股尼龙套线应用新式的缝合方法经末节指骨隧道重建指伸肌腱终腱止点。术后患指伸直位固定4周。 结果 术后随访时间为2个月至2年,无发生肌腱再次断裂。依据手指总主动活动度评定方法(TAM)进行评定:优20例,良6例,优良率达到100%。 结论 采用新式缝合法重建指伸肌腱终腱止点,是简便、有效、可靠的。
Objective To introduce a new method for reattachment of the terminal part of the tendons of digital extensors. Method The distal interphalangeal joint was fixed in the straight position by Kirschner wire with a diameter of 1.0 mm; a transverse bone tunnel in the base of the distal phalanx was drilled by Kirschner with 1.0 mm in diameter, through which 3/0 double-strand nylon lines were passed through; And the terminal part of the tendons of digital extensors were reattached to the distal phalanx by using the nylon lines. The fingers were maintained in a straight position for 4 to 6 weeks. Results Postoperative following-up 3 months to 2 years was carried out, no case of tendon rupture again was found. Finger total active movement (TAM) evaluation: Excellent in 20 cases, Good in 6 cases, Excellent rate was 100%. Conclusion The suture in reconstruction of terminal extensor tendon insertion is simple in operation, reliable at curative effect.
