Repair of chronic flexortendon rupture in zone II with seprafilm and tendongraft

Abstract

：Objective To report theclinical results of repairing flexor tendon rupture in zone Ⅱ with seprafilm and tendon graft. Methods Twerty-seven patients with chronicflexor tendon rupture in 36 fingers were treated with tendon graft and seprafilm, themedical absorbable biomembrane. Postoperatively systematic rehabilitation exercises werecarried out. Clinical results were observed. Results Primary healing was achieved in allof the 36 fingers of the 27 patients. Postoperative follow-up ranged from 4 to 36 months,with an average of 13 months. Evaluation using Strickland and Glogovac criteria revealedexcellent results in 10 fingers,good in 17 fingers, and fair and poor in 9 fingers. Thesatisfactory rate was 75 %. Recurrence of tendon rupture was absent. Tenolysis was carriedout in the 9 fingers with poor results 3 months later. Another 3-month follow-up studythat reevaluated the functions of the fingers showed excellent results in 2 fingers, goodin4 fingers, and fair and poor in 3 fingers. The satisfactory rate was 92%. ConclusionTreatment of chronic flexor tendon rupture in zone Ⅱ with seprafilm and tendon graft led to satisfying results.Secure suturing of the tendon, application of absorbable biomembranes and systematicpostoperative rehabilitation exercises are the key to good clinical effect.
