Abstract

Purpose: The objective of this study was to evaluate the clinical outcome of extensor tendon transfer that involves
increased tensioning for delayed repair of ruptured finger extensor tendons.
Materials and Methods: Eighteen patients (11 women and 7 men) with old ruptures of one or more finger extensors underwent tendon transfers was evaluated. Instead of the standard tensioning, the tensioning was performed with the thumb or finger in full extension and the wrist in the neutral position during the tendon transfers.
Results: The mean overall range of motion of the fingers improved from 115° preoperatively to 160° postoperatively.
The mean extension lag improved from 47° preoperatively to 11° postoperatively. The mean fingertip to palm distance was 0.2 cm preoperatively to 0.6 cm postoperatively. The mean finger grip strength was 35 g preoperatively to 27 g postoperatively.
Conclusion: Extensor tendon transfer with increased tensioning is a reliable alternative for the reconstruction of
chronic ruptures of finger extensor mechanism.
