Basalglengelelleinsätze

Basalglengeleinsätze, also known as basal joint implants or trapeziometacarpal (TMC) joint replacements, are surgical procedures designed to address severe osteoarthritis or degenerative arthritis of the trapeziometacarpal joint, commonly referred to as the "base of the thumb." This joint is critical for grip strength, pinch force, and overall hand function, making its dysfunction particularly debilitating.

The procedure involves the removal of the damaged cartilage and bone surfaces within the TMC joint, followed by the insertion of an artificial implant. These implants are typically made from materials such as silicone, pyrolytic carbon, or metal alloys, depending on the specific design and manufacturer. The goal is to restore joint stability, reduce pain, and improve hand function, particularly in activities requiring thumb opposition and grip.

Indications for basalglengeleinsätze include chronic pain, stiffness, and functional impairment due to advanced TMC joint arthritis that has not responded to conservative treatments such as anti-inflammatory medications, splinting, or corticosteroid injections. Candidates for the surgery are usually patients with significant joint degeneration, limited range of motion, and those who rely heavily on their hands for daily activities or work.

The surgery is performed under regional or general anesthesia, with the procedure lasting approximately one to two hours. Recovery typically involves a period of immobilization followed by gradual rehabilitation to restore strength and mobility. Complications, while rare, may include implant loosening, infection, or persistent pain, and long-term outcomes can vary depending on the patient’s overall health and adherence to postoperative care.

Basalglengeleinsätze are considered a last-resort treatment option due to the risks associated with joint replacement and the potential for implant-related complications. However, for carefully selected patients, the procedure can significantly improve quality of life by alleviating pain and restoring hand function.
