From suture to function: Evaluating an early functional rehabilitation approach for flexor tendon repairs in the context of current concepts.

Evaluating an early functional rehabilitation approach for flexor tendon repairs in the context of current concepts ABSTRACT

Background

In recent years, an increase in scientific research on the post-treatment of flexor tendon repairs has been observed. To evaluate the effectiveness and safety of the "Early-Active-Motion" concept that has been used in our clinic for over 10 years, a prospective study was developed that detailed both functional outcomes and complication rates over a period of 3 months.90 flexor tendon repairs in Zones 1-3, with and without accompanying injuries, were examined after three, six, nine and 12 weeks. Compliance was not a reason for exclusion. The collected parameters included the DASH, finger mobility according to the Strickland-Score, and other assessments.Out of a total of 90 flexor tendons, follow-up was achieved on 67 over a period of three months. Overall, 43 of the tendons achieved an excellent or good outcome. 20 had a fair outcome, and 4 of the digits had a poor Strickland Score. A total of three ruptures were documented.The "Early-Active-Motion" concept achieves a functionally good outcome with a Strickland-Score of 76 points. It is applicable from Zone 1 to Zone 3, even in complex flexor tendon injuries. Early phase deterioration appears to be an indicator of lower final outcomes.
