New perspectives on extensor tendon repair and implications for rehabilitation.
This article reviews the available biomechanical and clinical studies on extensor tendon repair and postoperative management. Immobilization has been a foundation for the postoperative treatment of these injuries, with good or excellent results ranging between 54% and 95%. However, clinical outcomes have consistently improved when utilizing rehabilitation involving either dynamically assisted or active motion, with good or excellent results achieved in at least 90% of cases. In addition, available biomechanical studies concerning finger extension strength, tendon repair strength, tendon shortening, resultant loss of motion, and gliding capability have validated controlled motion as biomechanically sound utilizing contemporary repair techniques.
