title: Rupture rate following primary flexor tendon repair of the hand with potential contributing risk factors.
abstract: This study aimed to investigate rupture rates following primary flexor tendon repair and to identify potential risk factors of rupture. Fifty-one patients with 100 flexor tendon injuries who underwent primary repair over a one-year period were reviewed. We collected demographic and surgical data. Causes of rupture were examined. Ruptured primary tendon repairs were compared with those that did not rupture. Univariate and multivariate analysis were undertaken to identify significant risk factors. Eleven percent of repaired tendons ruptured with a higher rupture rate noted in the non-dominant hand (p value = 0.009), in Zone II (0.001), and when more than 72 hours surgical delay occurred (0.01). Multivariate regression analysis identified repair in Zone II injuries to be the most significant predictor. Our rate of rupture of 11% was associated with delay in surgery, repair on non-dominant hand, and Zone II repairs. Careful consideration of these factors is crucial to reduce this rate.
