Unilateral Primary Osteoarthritis of the First CMC Joint: Symptoms, Diagnosis, and Treatment
Unilateral primary osteoarthritis of the first carpometacarpal (CMC) joint is a degenerative condition that affects the joint at the base of the thumb. It is characterized by the gradual breakdown of the cartilage, causing pain, stiffness, and limited mobility in the thumb. This condition commonly occurs in individuals over the age of 50, although it can also develop earlier in those with a history of joint trauma or repetitive stress on the thumb.
Symptoms of unilateral primary osteoarthritis of the first CMC joint may include swelling, tenderness, and the formation of bony growths called osteophytes. These symptoms can significantly impact daily activities that involve gripping, pinching, or grasping objects. The condition is typically diagnosed through a physical examination, medical history review, and imaging tests such as X-rays.
Treatment options for this condition aim to alleviate pain and improve thumb function. Non-surgical approaches may involve lifestyle modifications, splinting, medication, and physical therapy. In severe cases, surgical interventions like joint fusion or joint replacement may be considered.
Early diagnosis and timely management are crucial in minimizing the impact of this condition on an individual’s quality of life. Consulting with a healthcare professional is recommended for an accurate diagnosis and personalized treatment plan.
