  • Title: Tendon function after replantation: prognostic factors and strategies to enhance total active motion.
    Author: Ross DC, Manktelow RT, Wells MT, Boyd JB.
    Journal: Ann Plast Surg; 2003 Aug; 51(2):141-6. PubMed ID: 12897516.
    Abstract:
    The purpose of this study was to determine the important prognostic factors for recovery of tendon function as measured by total active movement (TAM) in patients undergoing digital replantation. More important, the authors wanted to establish which factors may be manipulated to maximize motion. A retrospective review of 48 patients (103 digital rays) who underwent replantation was performed. Average TAM for all digits was 129 deg. Zone 1 and zone 5 injuries had better TAM than injuries in zones 2, 3, and 4, which had TAM values not significantly different from one another. Avulsion injuries fared significantly worse than other mechanisms of injury. TAM values were not affected by age, type of bone fixation, number of arteries repaired, or number of digits injured. Digits with both the profundus and the superficialis tendons repaired had significantly better TAM values relative to one-tendon fingers. Similarly, fingers treated with an "early" mobilization regime also exhibited better movement. Small numbers of injured digits in some groups may have limited our ability to detect significant differences.
