Early controlled passive motion regime for zone II extensor tendon injury--a case report.

Zone II extensor tendon injuries are often associated with sharp laceration and saw injuries. These injuries are usually been immobilized for 4 to 6 weeks with static splint followed with gradual increment in ROM at distal interphalangeal (DIP) joint. Zone II injuries are usually associated with stiff DIP joint. Any effects taken to improve the DIP joint flexion aggravates the extensor lag at DIP joint. We report a dynamic passive mobilization regime for treating zone II extensor tendon injuries. We found dynamic passive mobilization program was effective in managing these injuries in preventing the DIP joint stiffness.
