The correlation between controlled range of motion with dynamic traction and results after flexor tendon repair in zone II.

Abstract

This prospective study investigated the extent to which the range of interphalangeal joint motion during early mobilization with dynamic traction influences the results after flexor tendon repair in zone II. The controlled interphalangeal joint range of motion within the splint was measured 3 weeks postoperatively in 51 digits (48 patients). The active range of motion was measured 4 weeks, 6 weeks, and 1 year postoperatively. Linear regression analysis showed that controlled interphalangeal range of motion had a significant effect on both early and late results. The results provide, for the first time, firm clinical evidence to support the rationale for early mobilization programs designed to maximize controlled interphalangeal joint range of motion.
