目的 探讨屈肌腱松解术中利用生物膜重建A2滑车的手术方法及临床疗效.方法 自2015年7月至2016年12月收治10例手指部屈肌腱粘连患者,术中松解屈肌腱后,滑车系统无法原位修复时,利用生物膜制成含有底座(和肌腱周围组织牢固结合)和滑车主体的生物膜重建A2滑车,术后在支具保护下进行功能锻炼.结果 术后10例10指切口均Ⅰ期愈合,切口无异物反应,无异常渗液,术区无红、肿、热、痛,未出现切口不愈合或延迟愈合.术后48 h内采用Strickland和Glogovac评价标准评定:优4指,良6指.经术后6～18个月(平均11个月)的随访,按Strickland和Glogovac评价标准评定:优4指,良6指.无一例发生肌腱再次断裂.随访手指总的屈曲活动度均有所改善,为135°～ 260°,平均200°.术后患指均未出现弓弦指畸形.结论 肌腱松解术中采用生物膜重建A2滑车,提供了一种新的滑车重建材料,是一种简便易行、效果可靠的方法.“,”Objective To explore the surgical technique and clinical efficacy of biological membrane for reconstruction of A2 pulleys in flexor tenolysis.Methods From July 2015 to December 2016,10 cases of digital flexor tendon adhesion were treated.When the pulley system could not be repaired in situ after flexor tenolysis,pulley base (firmly combined with the tissue around the tendon) and body were made from biological membrane to be used for reconstruction of A2 pulleys.After the operation,functional exercises were performed under the protection of braces.Results All the wounds achieved primary healing after the operation.No foreign body reaction,abnormal exudation,redness,swelling,heat,pain,non-union or delayed union occurred.According to the evaluation criteria of Strickland and Glogovac,the results were graded as excellent in 4 fingers and good in 6 fingers within 48 hours after operation.The patients were follow-up form 6 to 18 months with the average of 11 months.According to the evaluation criteria of Strickland and Glogovac,the results were graded as excellent in 4 fingers and good in 6 fingers.No tendon rupture occurred again.The total flexion activity of fingers was improved,ranging from 135° to 260° with an average of 200°.No bowstring deformity occurred in the affected fingers after operation.Conclusion Biological membrane could be used for reconstruction of A2 pulley,which provides a new material for pulley reconstruction in tenolysis.It is a simple and effective method.
