After the hand fracture is repositioned, it is usually fixed for about 3 weeks, and those with unstable repositioning are fixed with kerf pins for early activity. Simple exercises can usually be done after removal of fixation or to restore function in activities of daily living. Intensive rehabilitation is required only when there are other soft tissue injuries and extensive scar adhesions. The rehabilitation treatment after fracture is carried out in stages: the fixation period of the fracture corresponds to the middle postoperative period, and the rehabilitation treatment is carried out according to the principles of rehabilitation treatment in the early and middle postoperative periods, respectively. In the later stage, when the hand function stops progressing, the decision to stop treatment or consider further surgery is based on whether the hand function meets the basic requirements of the patient’s life and work. (1) Metacarpal fracture (a) Metacarpal base fracture: generally not strictly fixed, early activity when the swelling and pain are reduced, usually does not cause significant functional impairment (b) Metacarpal stem fracture: fixed for 3 weeks after repositioning, encourage the movement of uninvolved fingers and full upper limb activity during the fixation period, start to move the affected hand after removing external fixation, encourage the affected hand to engage in activities of daily living. After internal fixation of the plate with obvious displacement, early resumption of activities is also possible. (c) Metacarpal neck fracture: good repositioning is required to avoid damage to the fist arch and stiffening of the metacarpophalangeal joint. Active activities can be performed after 3 weeks of fixation. Fracture of the phalanges: Fixation for 2 weeks after repositioning to wait for the swelling and pain to subside, and appropriate activities after removal of fixation. In case of unstable repositioning, fixation with kyphoscopic pins should be used to allow early activity as possible. If the joint stiffness is caused by the delay of early activity, physical therapy and joint mobility exercises should be done within 2-3 months. Bennet fracture generally does not require special rehabilitation after perfect clinical treatment. In case of secondary osteoarthritis, hormone therapy, local braking with appropriate brace for several weeks and physiotherapy can be considered. Navicular fracture requires long-term fixation (>6 weeks), and after removal of external fixation, special rehabilitation treatment is generally not required. After surgical treatment of navicular osteonecrosis, rehabilitation can be done as appropriate. V. Joint fracture Simple metacarpophalangeal or interphalangeal joint fracture can be considered for local injection of corticosteroid when the swelling and pain are reduced and the pressure pain in the lateral collateral ligament area persists. If there is obvious joint instability, apply local brake for 3 weeks. Physiotherapy when there is continuous swelling and pain, and joint mobility exercises when joint movement is limited. Joint dislocation After dislocation, fix the hand in a functional position for 3-4 weeks, and then start local rehabilitation therapy. If the joint dislocation is accompanied by extensive soft tissue injury, the functional recovery will be slow. After removal of fixation, systematic joint mobility exercises and muscle strength exercises are recommended, combined with physical therapy.
