Two-Stage Reconstruction of Flexor Tendon in Hand

Abstract

• Background: Flexor tendon injures, especially in zone II, need primary repair. It is obvious that in case of not repairing it primarily or repair failure, one or two-stage flexor tendon reconstruction become necessary. The aim of this study was to determine the results of two-stage reconstruction of hand flexor tendons in zone II. • Methods: In a cross-sectional study, all patients underwent two-stage reconstruction surgery of finger flexor tendon in Alzahra and Kashani hospitals in Isfahan from 2001 to 2007 were selected in a simple-sampling method. Age, sex, mechanism of injury, initial performed treatment, along with lesions (digital nerves or arteries), presence or absence of local and phalanges fractures, motion weakness sensory status of finger at the admitting time, indication for reconstruction, rate of improvement and ultimate satisfaction was recorded. • Finding: Thirty one patients with average age of 26.09 ± 9.62 years that 71% of them were men were included in the study. Before operation, 87.1% of patients had weak finger range of motion; 3 months after operation, 67.7% of them had relatively weak range of motion at the end of study only; 25.8% of patients had very weak range of motion 6 moths after surgery (P < 0.001). 45.2% of patients were satisfied and none of them were unsatisfied or completely unsatisfied. • Conclusion: Two-stage flexor tendon reconstruction in hand in zone two is the method of choice for secondary repair or managing tendon repair complications.
