title: Early controlled active mobilization with dynamic splintage for treatment of extensor tendon injuries.
abstract: Early controlled active mobilization with a dynamic splint for treatment of repaired extensor tendon injuries was studied prospectively. Postoperative dynamic splintage started on the third postoperative day and involved elastic band extension and active flexion of the digits. Mobilization of the digits within the splint was done immediately under supervision. Range of motion was stepped up progressively and splintage was stopped after 5 to 6 weeks. Thirty-eight patients with 48 digits were reviewed. The average follow-up was 6.7 months (range, 4 to 10 months). Injuries involving the fingers showed an average final total active motion of 229 degrees (range, 95 to 270 degrees), whereas injuries involving the thumb was 118 degrees (range, 78 to 150 degrees). Lesions distal to the knuckles (zones II, III, IV) showed the worst results with an average total active motion of only 188 degrees (range, 95 to 270 degrees). The duration out of work was 8.5 weeks (range, 4 to 25 weeks). There was no infection or acute tendon rupture. One patient required reconstruction of a persistent button-hole deformity; two required tenolysis and capsulotomy. Of the six unsatisfactory results with poor total active motion, four had injuries distal to the metacarpophalangeal joint, three of which were crushing injuries.
