Tendons attach muscles to bones and allow movement of the hand. Frequently injured in home or work accidents, tendon injuries require special operative repair techniques and knowledgeable postoperative management to obtain the best functional results. Extensive tendon injuries can often times be repaired in an office or emergency room setting. Flexor tendon lacerations frequently require a more complex surgical challenge and usually require a more formal operating room repair in an outpatient setting. Postoperatively, patients usually require several weeks of protective splinting and graduated activity managed by an occupational therapist.
