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.
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.
Arthritis is a condition that irritates or destroys a joint. Although there are several types of arthritis, the one that most often affects the joint at the base of the thumb the basal joint is osteoarthritis degenerative or "wear-and-tear" arthritis. Smooth cartilage covers the ends of the bones. It enables the bones to glide easily in the joint.
LRTI stands for ligament reconstruction and tendon interposition. Joints are formed where two bones meet. Your joints are lined with smooth tissue known as cartilage.
The goal of successful treatment of thumb basal joint arthritis is relief of pain with retention of motion and stability. Fusion by various techniques 12 achieves relief of pain but at the cost of lost motion. Arthroplasty for the base of the thumb has gone through many refinements over the years.
Pain in the basal joint caused by arthritis makes it difficult for patients to grip and hold or twist objects between the thumb and fingers. This surgical procedure removes and rebuilds the basal joint. Arthritis of the thumb, also known as basal joint arthritis, occurs when the cartilage of the thumb joint carpometacarpal joint wears away from the bone.
Arthritis at the base of the thumb is one of the most common locations and can be very disabling. Because the strength and motion of the thumb is required for nearly every activity - whether writing, opening a jar, or buttoning a shirt - pain from this condition may impede the most basic everyday tasks. Like other forms of osteoarthritisbasal thumb arthritis develops when cartilage on the surfaces of the bones that meet at the joint wears away and the metacarpal bone begins to slip out of the joint. This loss of alignment often creates the appearance of a bump near the wrist.
During a physical exam, your doctor will ask about your symptoms and look for noticeable swelling or lumps on your joints. Your doctor might hold your joint while moving your thumb, with pressure, against your wrist bone. If this movement produces a grinding sound, or causes pain or a gritty feeling, the cartilage has likely worn down, and the bones are rubbing against each other.
Review the clinical presentation of basal joint arthritis, conservative management strategies, when surgery is indicated, and what patients can expect after surgery. The basal carpometacarpal joint is the second most common location for osteoarthritis in the wrist and hand, and is the most common arthritic condition of the upper extremity to be treated with surgery. Basal joint arthritis is usually seen in patients aged 50 to 70, and occurs more frequently in women than men.
