Abstract

Background: Open extensor tendon disruptions occur frequently and may lead to significant disability.
Aim of this work: This research aimed to assess the impact of usage of early active mobilization at the rehabilitation following extensor tendon injuries, as regard to: Joint stiffness and restoring normal hand function.
Patient and Methods: This was a prospective case series research, on 20 cases in Al-Azhar University hospitals, Plastic Surgery Department.
Results: There was highly significant improvement in hand function in for MCP, PIP, and DIP, 15 patient restored their normal hand function at the 6th week, four patient with extension lag than 20 degree at the 6th  week 2 of them improved at the 12th week, one patient with flexion deficit less than 10 degree at the 6th  week improved at the 12th  week, two patient of 20 with permanent deficit, The results demonstrate that improvement flexion deficit in MCP, PIP, and DIP joints over time, our study findings emphasize the effectiveness of the treatment in reducing flexion deficit and enhancing finger joint flexibility.
Conclusion: We concluded that the relative motion splinting technique is effective in rehabilitating extensor tendon injuries by reducing rehabilitation time, restoring hand function, and reducing physiotherapy. The patient showed lower flexion deficits in MCP, PIP, and DIP joints, with gradual reduction over time and improved flexion capabilities.
