Physiotherapy after thumb extensor tendon repair in Verdan zone III. Case study.

BACKGROUND Finger tendon injuries represent very common consequences of hand injuries and, if not properly treated, can lead to substantial hand function impairment and interfere with activities of daily living. This article presents the results of rehabilitation of a female patient after thumb extensor tendon injury in Verdan's zone III. MATERIAL AND METHODS Based on standard diagnostic work-up (assessment of the active range of motion), we calculated the degree of functional hand function impairment according to Swanson's method. The diagnostic procedures also comprised measurements of dynamometric grip strength and precise grasp. The examinations were performed on four occasions, the first one during the first visit, and the last one a month after completion of the rehabilitation treatment in our Centre. RESULTS Test results were used to design the treatment programme, which included among others the author's modification of Kleinert's dynamic reverse thumb splinting, peg-board exercises, physical therapy, individual therapy and home-based exercises. CONCLUSIONS 1. The modified dynamic splint of our design fulfilled its task as both a preventive and therapeutic measure. 2. The dynamic splinting programme administered enabled early initiation of post-operative rehabilitation, which led to a very high degree of recovery of thumb and hand function. 3. The functional recovery outcomes achieved by our patient indicate the advisability of routine incorporation of full dynamic splinting in post-operative rehabilitation programmes of patients with thumb extensor tendon injuries.
