指浅屈肌腱束修复指间关节侧副韧带断裂

REPAIR OF COLLATERAL LIGAMENT RUPTURE IN THE INTERPHALANGEAL JOINT USING SUPERFICIAL FLEXOR TENDON OF FINGER

目的 介绍应用指浅屈肌腱束加强修复近节指间关节侧副韧带断裂的方法及疗效。方法 自1987 年以来,对23 例23 指近节指间关节侧副韧带断裂,采用部分指浅屈肌腱显微技术加强修复。用细克氏针在侧副韧带起点处向健侧钻两个相距23 m m 骨孔穿过钢丝,切开屈肌腱鞘,从指浅屈肌腱一侧近端切取所需长度肌腱束,此肌腱束穿过钢丝孔,保持肌腱束的合适张力,用5/07/0 无创线缝合于浅腱止点,应用8/0 针线将肌腱束缝合于韧带上。术后伸直位夹板固定46 周。结果 经36 个月随访,优15 例,良6 例,可2 例,优良率91-34% 。结论 应用指浅屈肌腱束显微技术加强修复近节指间关节侧副韧带断裂,手术损伤小,就地取材,是一种较简便。

Objective To introduce the surgical procedure and clinical result of microsurgical repair on collateral ligament rupture in the interphalangeal joint using superficial flexor tendon of finger. Methods\ From 1987, 23 cases with collateral ligament rupture in the interphalangeal joint were repaired by part of superficial flexor tendon of finger. The initial point of collateral ligament was drilled two holes, 2 to 3 mm in distance, and crossed by steel wire. Then the superficial flexor tendon of finger was crossed under the steel wire and sutured to the terminal point of superficial flexor tendon of finger by 5/0 to 7/0 nontraumatic suture thread to maintain suitable tension, and sutured to collateral ligament by 8/0 nontraumatic suture thread. Extension splint fixation was performed 4 to 6 weeks postoperatively. Results\ Followed up 3 to 6 months, 15 cases were excellent, 6 cases were better, 2 cases were moderate, and the excellent rate was 91.34% according to Saetta standard. Conclusion Microsurgical repair on collateral ligament rupture in the interphalangeal joint using superficial flexor tendon of finger is a convenient and effective surgical method.
