Abstract
Purpose. This study aims to compare the effect of early ultrasound (US) therapy to early active mobilization (EAM) on the outcomes “Range of motion (ROM) and rate of tendon ruptures” of zone II flexor tendon repair. Subjects and Methods. 20 male patients (31 operated digits), who underwent zone II flexor tendon 4-strand repair, were divided randomly into 2 groups: Group (A); 10 patients (15 operated digits) who received early US therapy, and Group (B); 10 patients (16 operated digits) who received EAM. Patients received the treatment (3 sessions/week) from the 3rd day till the end of the 6th week postoperative. Active interphalangeal (IP) joints’ ROM of each operated digit was measured using finger goniometer and Strickland’s Original Scoring System was used to evaluate the ROM outcome at end of the 3rd and 6th postoperative weeks. Tendon ruptures were counted in each group if it occurred. Results. There was a significant improvement in the ROM outcome at end of the3rd and 6th week postoperative in group B compared to group A while no tendon ruptures occurred in either of the groups. Conclusion. The EAM seems to be superior over early US therapy in the improvement of the ROM outcome of zone II flexor tendon repair while both show no tendon ruptures.

Key words:
early ultrasound therapy, early active mobilization, flexor tendon repair
