Reconstruction of the collateral ligament of the metacarpophalangeal (MCP) joint is a surgical procedure aimed at addressing injuries to the ligament that may occur due to trauma, such as lacerations or ruptures. The collateral ligaments are critical for the stability of the MCP joint, which is located at the base of the fingers. When these ligaments are compromised, it can lead to instability and impaired function of the hand. The procedure involves either the use of local tissue, such as in the case of adductor advancement, or the application of a graft from another tendon or fascia. The choice of technique depends on the nature and extent of the injury. In cases where an open wound is present, the surgical approach includes exploration of the wound, debridement of any devitalized tissue, and removal of foreign materials. For closed injuries, a volar incision is made to access the MCP joint, allowing for careful dissection to protect neurovascular structures while evaluating the extent of the ligament injury. The reconstruction aims to restore the integrity and function of the MCP joint, facilitating a return to normal hand activities.
