This study retrospectively analyzes primary extensor tendon repairs in children younger than 15 years.
Exclusion criteria were skin loss, devascularization, fractures, or flexor tendon injuries. Fifty patients who had sustained extensor tendon laceration with 53 digits injured were available for review. Treatment consisted of primary repair of the extensor tendon injury within the first 24 hours. The results were assessed by means of total active motion system and by Miller's rating system. The mean follow-up was 2 years.
Although 98% of the digits were rated as good or excellent according to the total active motion system and 95% according to Miller's classification, 22% of the fingers showed extension lag or loss of flexion at the last follow-up.
Pejorative influencing factors were injuries in zones I, II, and III; children younger than 5 years (P < 0.05), and complete tendon laceration. Articular involvement had no significant influence on final outcome.
