What is trapeziometacarpal arthritis?
What is trapeziometacarpal arthritis?
Trapeziometacarpal (TM) joint arthritis is a common cause of radial-sided wrist pain that preferentially affects women. It is diagnosed by a thorough history, physical examination, and radiographic evaluation. While radiographs are used to determine the stage of disease, treatment is dependent on symptom severity.
What does trapeziometacarpal mean?
Trapeziometacarpal osteoarthritis, also known as osteoarthritis at the base of the thumb or as rhizarthrosis, is a reparitive joint disease affecting the first carpometacarpal joint (CMC1). This joint is formed by the trapezium bone of the wrist and the first metacarpal bone of the thumb.
What type of joint is the trapeziometacarpal joint?
incongruous saddle joint
The trapeziometacarpal joint is commonly referred to as an incongruous saddle joint. It makes possible the wide circumduction of the thumb, enabling activities such as grasping and pinching [2], that involves three arcs of motion: flexion–extension, abduction–adduc- tion, and pronation–supination.
Why is the carpometacarpal joint important?
The carpometacarpal (CMC) of the thumb is a saddle joint that permits a wide range of motion and is largely responsible for the characteristic dexterity of human prehension. This joint, located at the very base of the thumb, is subject to large physical stresses throughout life.
What is the TMC joint?
The TMC joint or CMC joint is formed by the first metacarpal bone of the thumb and the trapezium (carpal) bone of the wrist. The joint is located at the base of the thumb and attaches the base of the thumb to the wrist and the base of the fingers to the hand.
Which joint in the body is known as the saddle joint?
sellar joint
Ligaments of wrist. Posterior view. A saddle joint (sellar joint, articulation by reciprocal reception) is a type of synovial joint in which the opposing surfaces are reciprocally concave and convex. It is found in the thumb, the thorax, the middle ear, and the heel.
What is the first carpometacarpal joint?
The 1st CMC (carpometacarpal) joint is a specialized saddle-shaped joint at the base of the thumb. The trapezium carpal bone of the wrist and the first metacarpal bone of the hand form the 1st CMC or thumb basal joint.
What helps with basal joint pain?
Treatment of basal joint arthritis
- Self-help. Try to avoid clenching your hands when you carry things, as this can aggravate symptoms.
- Medications. Try an over-the-counter pain reliever or anti-inflammatory medication.
- Splints.
- Surgery.
How is surgery used to treat trapeziometacarpal arthritis?
Surgical treatment of trapeziometacarpal joint arthritis: a historical perspective Many procedures have been described to treat TMC joint arthritis, from simple trapezial resection to complex soft tissue arthroplasty to prosthetic arthroplasty.
How is surgery used to treat TMC arthritis?
The evolution of surgery for TMC joint arthritis both parallels and diverges from that in other joints. For example, for most degenerated joints (even many in the hand), treatment evolved from resection arthroplasty to implant arthroplasty.
When did they remove the trapezium from the thumb?
In the 1940s, for the painful, arthritic TMC joint, the most direct approach was resection of the trapezium. Sixty years ago, Gervis [ 13] published his clinical results after excising the trapezium in 15 patients with painful thumb CMC joint arthritis.
When did Murley publish his experience with trapeziectomies?
In 1960, Murley [ 26] published his experience with 39 trapeziectomies performed between 1946 and 1956. His operative procedure differed little from that described by Gervis but did include plaster immobilization for 3 weeks.
