Triceps-to-Biceps Tendon Transfer Technique for Restoration of Elbow Flexion in Adult Brachial Plexus Injury

Restoration of elbow flexion is a priority in treating adult traumatic brachial plexus injuries. A tendon transfer is an ideal option for patients not candidates for reconstructive nerve surgery or free-functioning muscle transfer. For patients with a partial brachial plexus injury or a pan plexus injury with adequate recovered triceps function and loss of elbow flexion, a triceps-to-biceps tendon transfer is a nonmicrosurgical option to restore elbow flexion. The technique of triceps-to-biceps transfer in which the complete triceps tendon is transferred laterally, secured lateral to the radial tuberosity, and reinforced with suture to the biceps tendon is described.
