三角钢丝固定法在近指间关节周围断指再植中的应用

目的 评价在近指间关节周围断指再植时采用三角钢丝内固定法的临床疗效.方法　13例(19指)近指间关节周围的断指,其中中节基底13指,近节远端6指,断指再植时采用三角钢丝内固定法重建骨支架.结果　术后平均7周达骨愈合,近指间关节活动范围5°～84°.参照中华医学会手外科学会上肢部分功能试用标准进行评定,本组中优15指,良3指,差1指,优良率为94.7％.结论　在近指间关节周围断指再植时,采用三角钢丝法进行内固定,操作简便,有效固定的同时可允许早期开展关节功能训练,恢复良好的关节功能,临床效果满意.     

Reoperation After Operative Fixation of Proximal Interphalangeal Joint Fractures

Background: The purpose of this study was to determine the reoperation rate and what factors are associated with reoperation of proximal interphalangeal (PIP) joint fractures. Methods: We identified 161 surgically treated PIP joint fractures between 2004 and 2015 at 2 academic medical systems. Demographic, injury, radiographic, and treatment data that might be associated with reoperation were collected. Bivariate analysis was performed. Factors identified during bivariate analysis with a P < .10 were entered into a multivariable logistic regression analysis. Results: Of the 161 fingers, 25 underwent revision surgery. Open fracture was independently associated with revision surgery. The most common indication for reoperation was joint stiffness (35%). In a subanalysis of 111 closed fractures, no factors were associated with revision surgery. Conclusions: Soft tissue injury is a major factor in reoperation after PIP joint fracture dislocation. Specific attention should be paid to persistent subluxation because this may predispose to early arthrosis.     

延期切开复位植骨钢板内固定治疗Pilon骨折

目的探讨延期切开复位结合植骨三叶草钢板内固定治疗Pilon骨折的疗效。方法 26例Pilon骨折患者,6例为开放性骨折,20例为闭合性骨折,对闭合性骨折先行跟骨牵引治疗,待肿胀消退后行切开复位结合植骨三叶草钢板内固定治疗。结果 26例均获术后随访,随访时间842个月。骨折临床愈合时间为1628周,患肢力线正常。术后有3例伤口感染,3例皮肤坏死,5例踝关节功能障碍;未见有骨折不愈合或畸形愈合,无窦道形成及骨髓炎。临床疗效按美国足与踝关节协会踝与后足功能评分：优6例（90100分）,良14例（7589分）,可3例（5074分）,差3例（小于50分）。结论正确评估局部软组织条件,根据Pilon骨折的类型和软组织损伤程度选择合适的手术方式和手术时机,三叶草钢板内固定维持骨折复位和下肢力线,干骺端缺损区充分植骨,修复关节面,早期功能锻炼,晚负重,可使P ilon骨折术后达到良好的临床疗效。
