Treatment for Arthritis
Diagnosis of arthritis at the base of the thumb is based upon a carefully performed physical examination and review of medical history with confirmation by X-rays. This allows us to stage the arthritis as early, mild, moderate or severe.
In early stages, splinting and medications may be beneficial while more severe cases may require surgery. The goal of surgery is to eliminate the pain at the base of the thumb by creating a new joint. The procedure can improve the position of the thumb, its range of motion and the hand’s strength for pinching and grasping.
Two types of surgery are currently available to us to maintain motion. The traditional surgery, useful for patients with advanced disease, involves removing the entire trapezium bone and then using a tendon from the forearm to suspend the thumb and to act as an interposition material. This is referred to a “Ligament Reconstruction Tendon Interposition” Arthroplasty (LRTI).
In some cases it is possible to undergo arthroscopic surgery to remove bone spurs and place interpositional material to decrease pain and improve function.
