The loss of the functional position of the hand will seriously affect the function of the hand. The contracture of the dorsal hand scar leads to the metacarpophalangeal joint in the hyperextended position, the interphalangeal joint in flexion, the thumb inward, the little finger deviating to the ulnar side, and the disappearance of the longitudinal and transverse arches of the hand, forming the typical claw hand deformity. The treatment of clawed hands is a very complex and systematic project, and all deformities should be treated separately, while preserving the function of the hand as much as possible. The shoulder joint is one of the most mobile joints in the body and scar contracture will severely affect the voluntary movement of the shoulder joint. If the scar in the axilla extends to the trunk, the patient’s dressing, eating and posture will be affected; if the scar extends to the arm, the movement of the elbow joint will also be affected. The unique morphologic structure of the axilla causes this area to be susceptible to scar contracture after a burn injury. Treatment of axillary scar contracture: 1.Conservative treatment: Insist on exercising and wearing molds in the early post-burn period in order to preserve the abduction, supination and shoulder joint range of motion of the upper limb as much as possible. 2.Surgical treatment: (1) scar release and local reshaping: applicable to webbed axillary scar contracture. (2) Scar excision, relaxation and skin free transplantation surgery, which may cause contracture again. (3) Scar excision, release, local flap transfer repair surgery.
