Surgical arthroscopy of the metacarpophalangeal joint is a minimally invasive procedure that involves the use of an arthroscope to visualize and treat conditions affecting the joint. The metacarpophalangeal joint, commonly referred to as the MCP joint, is located at the base of the fingers where the metacarpal bones meet the proximal phalanges. This procedure is primarily performed to address issues such as arthritis, which can lead to pain, swelling, and reduced mobility in the fingers. During the arthroscopy, small incisions, known as portals, are made on the dorsal (back) side of the hand, specifically at the ulnar and radial aspects of the joint. These incisions allow for the insertion of the arthroscope, a specialized instrument equipped with a camera and light source, enabling the surgeon to inspect the interior of the joint for any signs of injury, disease, or infection. The procedure also includes debridement, which involves the removal of damaged or diseased tissue, including redundant cartilage, inflamed tissue, and bone spurs (osteophytes), to promote healing and restore joint function. The ultimate goal of this surgical intervention is to alleviate symptoms, improve joint function, and enhance the overall quality of life for patients suffering from MCP joint disorders.
