Abstract

Objective. To evaluate the effect of an early intervention of Low Level Laser Therapy (LLLT) on incisional wound scar formation and range of motion (ROM) of interphalangeal (IP) joints post surgical repair of hand flexor tendon laceration.
Material and methods. Thirty male patients between the ages of 20 and 40 who underwent unilateral zone II flexor tendon repair of the hand were assigned randomly into two equal groups in number of 15 patients each group. Group (A) (Laser therapy group) received early LLLT in addition to post surgical medical care while the group (B) (Control group) received only post surgical medical care. The primary outcomes were color, pigmentation, pliability and height of wound scars which was measured by Vancouver Scar Scale (VSS). In addition to Total Active Motion (TAM) of hand’s digits which measured by hand goniometer. The assessment was taken after 4 weeks and 12 weeks postoperative.
Results. After 12 weeks compared to after 4 weeks in both groups, there was a significant decrease in the VSS and a significant increase in Total Active Motion (TAM) according to within group comparisons (p < 0.001). When compared to the control group at 4 and 12 weeks, the laser group had a significantly lower VSS and a significantly higher TAM (p < 0.01).
Conclusion. Early applications of LLLT post surgical repair of flexor tendon improve TAM and minimize scar formation.

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
