Abstract
ABSTRACT:
BACKGROUND: The primary purpose of the relative motion orthosis is to provide protection for an acute, healing or fragile injury or repair. RME orthosis programs position the affected MCPs in exaggerated extension when compared to non-affected MCPs and also allow free motion of the IP joint. Flexor and extensor tendon lacerations are relatively rare affecting about 5 per 100,000 persons for flexor tendons and 14 per 100,000 persons for extensor injuries. While these injuries may be less common than other hand injuries, they present unique challenges When not treated appropriately extensor tendon lacerations can lead to permanent impairment and lack of hand function. Extensor tendon lacerations commonly affect working aged men in their 30’s who are working in manual labor and production-based careers. Extensor tendon injuries are most commonly occurring on the dominant hand in the middle finger. Complete tendon lacerations require surgical intervention while partial lacerations may heal over the course of 3-4 weeks with splinting intervention. When patients do not receive optimal pre and post-operative care they are more likely to develop sub-optimal tendon gliding, which leads to tendon ruptures and loss of function. Early return to work is the goal of treatment, patients receiving orthosis intervention before 5 days post operation display 97.8% of prior level of function range of motion.
