Meta-analysis of Flexor Tendon Transfer for the Correction of Lesser Toe Deformities

Background: Transfer of the flexor digitorum longus tendon is one of the surgical techniques described to treat lesser toe deformities. A global analysis of the benefits of this procedure has not been presented in the literature to date. The aim of this meta-analysis was to evaluate the clinical benefit of transfer of the flexor digitorum longus tendon regarding patient satisfaction. Methods: A reviewer formally trained in meta-analysis abstraction techniques searched several databases to identify relevant published studies. Initially, 203 citations were identified and evaluated for relevance. Abstract screening produced 112 articles to be read in their entirety, of which 17 articles studying 515 procedures with a mean ± SD follow-up of 54.21 ± 20.64 months met all of the inclusion criteria necessary for analysis. Results: Overall crude patient satisfaction after flexor digitorum longus tendon transfer was 86.7% (95% confidence interval, 81.7%–90.5%). A low grade of heterogeneity across studies (Q = 24.45...
