Abstract
The effects of a shortened post-operative mobilization programme following flexor tendon repair in zone 2 in the hand were examined in a prospective, randomized study. 91 digits in 82 patients were included in the study. All injured tendons were repaired within 24 hours and all patients were subjected to the same mobilization programme during the first 6 weeks using a passive flexionactive extension régime. After 6 weeks the patients were randomized into two groups; in group A full activity was allowed after 8 weeks while in group B unrestricted use of the injured hand was not allowed until 10 weeks after the tendon repair. Functional results were compared using the Louisville, Tsuge and Buck-Gramcko assessment systems. Grip-strength was measured 16 weeks after repair, subjective assessment of hand function was recorded on a visual analogue scale, and absence from work was registered. No significant differences were observed between the groups regarding functional results, rupture rates, grip strength or subjective assessment, but absence from work was reduced by 2.1 weeks with the shorter mobilization programme.
Using the described régime, full activity can be encouraged 8 weeks after flexor tendon repair in zone 2 of the hand without adverse effects on functional results or increased risk of rupture of the repair.
