Ruch, LRTI has a 96 percent success rate. Pros: Removing the entire trapezium eliminates the possibility of arthritis returning and, according to Dr. Who can benefit: Adults with moderate to severe arthritis who have pain and difficulty pinching or gripping. Surgeons can also use artificial “anchovies” that eliminate the need to move a tendon. The remaining tendon is rolled like an anchovy and placed into the space where the bone was removed. To accomplish this, surgeons remove all or part of the trapezium bone in the wrist at the base of the thumb. A nearby tendon is detached at one end and passed through a hole drilled in the thumb’s metacarpal bone. The damaged joint surfaces are removed and replaced with a cushion of tissue that keeps the bones separated. In use for more than 40 years, LRTI is the most commonly performed surgery for thumb arthritis. Ligament Reconstruction and Tendon Interposition (LRTI) Studies suggest ligament reconstruction also prevents disease progression in a majority of patients.Ĭons: The procedure stabilizes the joint but does not repair damaged cartilage or bone. Pros: Most people with very early arthritis experience good to excellent pain relief. Who can benefit: Adults with no cartilage loss whose symptoms result from looseness in the joint. “The transposed tendon reconnects and restores mechanical function of the thumb with the rest of the hand,” says Stephen Trigg, MD, an orthopedic hand surgeon at Mayo Clinic in Jacksonville, Florida. This procedure stabilizes the CMC joint by removing a portion of the damaged ligament and replacing it with a piece of the patient’s wrist flexor tendon. The best surgical approach depends on the stage of the disease and severity of symptoms. “ make people feel better, but they don’t stop disease progression, and eventually surgery may be necessary,” he says.
Ruch, these may be the only treatments needed. Ruch, MD, chief of the hand surgery at Duke Health in Durham, North Carolina, says women, especially those older than 50, are 10 to 20 times more likely than men to develop thumb arthritis, though no one is quite sure why. Both women and men respond well, at least initially, to conservative measures such as anti-inflammatory medications, splints, activity modification and limited steroid injections. Over time, the articular cartilage that cushions the ends of the bones wears away, causing pain and limiting movement. Rheumatoid arthritis (RA) and other forms of inflammatory arthritis can also damage the CMC joint in the thumb, also known as the trapeziometacarpal joint (TMC).ĭavid S. Metacarpal bones: bones of the hand between the carpals and theĬarpometacarpal joint (CM): joint of the carpus and metacarpus.Problems often start when the thick ligaments that hold the joint together loosen, allowing it to slip out of place. Proximal phalanx: small bone of a finger, closest to the palm Middle phalanx: small, middle bone of a finger. Third finger: second finger from the outside of the hand.įourth finger: small finger closest to the outside of the hand.ĭistal phalanx: bone at the end of a finger. Second finger: middle finger of the hand. Index: second finger of the hand, next to the thumb.
