CPT® Code 26852

Arthrodesis of the metacarpophalangeal (MCP) joint is a surgical procedure aimed at fusing the bones of the MCP joint, which connects the metacarpal bone of the hand to the proximal phalanx of the finger. This procedure is typically indicated for patients suffering from conditions such as arthritis or instability of the MCP joint, which can lead to pain and functional impairment. The surgery involves making an incision over the MCP joint to access the joint capsule, allowing for a thorough inspection of the joint surfaces. During the procedure, the articular cartilage from both the metacarpal head and the phalanx is excised to prepare the surfaces for fusion. The metacarpal is then smoothed and reshaped to ensure a proper fit with the phalanx. In some cases, internal fixation devices, such as pins or wires, may be utilized to maintain the desired position of the joint during the healing process. Additionally, in the case of CPT® Code 26852, a bone autograft is harvested from the iliac crest, which involves making a separate incision to obtain the necessary bone material. This graft is then shaped to fit the defect created by the excision of cartilage and is secured in place to facilitate the fusion of the joint. The procedure concludes with the repair of soft tissues in layers and the application of a short arm cast to support the hand during recovery.
