腱性锤状指的治疗

Experiences in the treatment of tendinous mallet finger

目的探讨使用部分屈指深肌腱转位重建手指伸指功能的效果.方法2017年4月至2018年9月苏北人民医院手足外科收治腱性锤状指患者13例,男4例,女9例,年龄35~55岁.采用屈指深肌腱Ⅰ区及部分Ⅱ区腱芯(肌腱中心部分)中间近端1/5切断,向基底牵拉,于末节指骨基底以2.0钻头打孔,将肌腱瓣穿孔洞引向背侧拉紧后与自止点撕脱的伸肌腱近断端进行编织缝合治疗.结果远侧指间关节固定4周后末节可主动屈伸,无屈曲畸形,随访3~18个月,平均随访时间10.6个月,采用Dargan功能评定法进行评定,12例优,1例差.结论通过部分屈指深肌腱重建伸肌腱止点撕脱,是一种治疗腱性锤状指的有效方法.

Objective To explore the effect of reconstructing the finger extension function by using partial flexor digitorum profundus tendon transposition. Methods Twelve patients were treated by using the partial proximal end of the tendon core of flexor digitorum profundus tendon regionⅠand part of region Ⅱ to cut off to the base of the distal digital phalanx, and puncturing at the end of the phalanx with a 2.0 drill. The tendon strips were pierced to the back overlap sutured to the proximal end of the avulsion of the extensor tendon . Results In 3-18 month follow-up, the average follow-up duration was 10.6 months. According to Dargan function evaluation method, 12 cases were excellent and one case was poor. Conclusions The method of reconstructing the extensor tendon by partial flexor deep tendon is a reliable method for the treatment of Mallet finger.
