The thumb joint at the base of the thumb is the most mobile in the hand. The thumb can move up and down, in and out, and rotate slightly to touch the fingers. We move our thumbs hundreds of times each day.
Infrapatellar strap reduces pain Osteoarthritis of the Base of the Thumb. The are many types of arthritis.
Language: English French. Based on the staging of the CMC OA, different forms of treatment can be used, including both conservative and surgical measures. Surgical options include osteotomy, trapezial excision, ligament reconstruction with or without tendon interposition, and various prosthetic interpositional implants with or without trapezial excision.
Thumb arthritis is common with aging and occurs when cartilage wears away from the ends of the bones that form the joint at the base of your thumb — also known as the carpometacarpal CMC joint. Thumb arthritis can cause severe pain, swelling, and decreased strength and range of motion, making it difficult to do simple tasks, such as turning doorknobs and opening jars. Treatment generally involves a combination of medication and splints. Severe thumb arthritis might require surgery.
Most activities that involve grasping or pinching are possible because of the thumb's remarkable range of motion. But dexterity comes at a price — an increased risk of osteoarthritis in the first carpometacarpal CMC joint, where the thumb meets the trapezium bone in the wrist. Sometimes the joint becomes so damaged that surgery is necessary.
The carpometacarpal CMC joints are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the five metacarpal bones. The carpometacarpal joint of the thumb pollexalso known as the first carpometacarpal joint, or the trapeziometacarpal joint TMC because it connects the trapezium to the first metacarpal bone, plays an irreplaceable role in the normal functioning of the thumb. The most important joint connecting the wrist to the metacarpus, osteoarthritis of the TMC is a severely disabling condition; up to twenty times more common among elderly women than in average.
A joint is formed when two bones meet and articulate, which allows movement. Joints are lined with smooth cartilage that allows for the easy movement of one bone relative to another. Osteoarthritisor degenerative arthritis, is a process that occurs with aging and describes the deterioration of the joint cartilage.
Collapse deformities of the thumb are all too common in the presence of CMC joint arthritis. This becomes a highly dysfunctional posture over time due to the loss of MCP flexion, web space shortening and thenar muscle atrophy - making moving the thumb away from the palm all but impossible. A targeted stretching and strengthening program and the use of a thumb orthosis designed to support and stabilize the CMC are key to maintaining function and to hopefully preventing, a permanent swan neck posture.
