目的：观察可吸收Mitek微型骨锚在修复腱性锤状指损伤中的疗效，并对可能存在的并发症进行评估。方法回顾性分析2008年9月—2011年5月治疗的22例腱性锤状指损伤，均采用可吸收Mitek微型骨锚重建伸肌腱止点，根据Watson-Jones分型，Ⅱ型14例，Ⅲ型8例。随访期间记录远指间关节活动范围、X线平片检查结果、主观满意程度及手术并发症情况，并按照Crawford功能评分标准评估疗效。结果伤指功能优18例，良3例，可1例。X线平片检查未见锚钉滑脱、局部骨质吸收。无皮肤溃疡或坏死、组织排斥反应、畸形复发等并发症。结论可吸收Mitek微型骨锚是修复腱性锤状指损伤的可靠方法，手术简便，并发症较少，作用确切。%Objective To observe the treatment outcome of absorbable min-bone anchor for rehabilitating the tendinous Mallet finger injuries, and evaluate the possible complications. Methods Between June 2008 and May 2011, 22 cases of tendinous Mallet finger injuries treated by using absorbable Mitek mini-bone anchor were retrospectively reviewed. According to the Watson-Jones classification, 14 cases of type II, 8 cases of type III. During the follow up, distal interphalangeal joint range of motion, X-ray results, subjective satisfaction of patients and corresponding complications were recorded, and curative effects were evaluated by Crawford functional scoring standard. Results Functional scores were excellent in 18 cases, good in 3 cases, fair in 1 case. X-ray results showed no slippage or loose of anchor, and no local bone absorption. There were no skin ulcer, pain, deformity recurrence and other complications. Conclusion Absorbable mini-bone anchor is a simple and effective treatment modality to reconstruct the tendinous Mallet finger injuries ,with less complications and exact curative effects.
