Diagnoses

Trigger finger

Trigger finger, or stenosing tenosynovitis, is a condition where a finger gets stuck in a bent position and may snap straight with a popping sound. It occurs when the tendon in the affected finger becomes inflamed or swollen, causing it to catch in the tendon sheath, a tunnel that allows smooth finger movement. Repeated strain or underlying conditions like diabetes, rheumatoid arthritis, or occupations involving frequent gripping can increase the risk. Common symptoms include stiffness, tenderness at the base of the finger, and a clicking or locking sensation when bending or straightening the finger. The ring finger and thumb are most often affected. In mild cases, rest, splinting, and anti-inflammatory medications may relieve symptoms. For persistent or severe cases, corticosteroid injections or minor surgery may be necessary to release the tightened sheath. Early diagnosis and treatment improve outcomes and help prevent long-term stiffness or permanent locking of the finger.

Carpal tunnel syndrome (CTS)

Carpal tunnel syndrome (CTS) is a condition caused by compression of the median nerve as it passes through the carpal tunnel in the wrist. This narrow passageway is surrounded by bones and ligaments, and swelling in the area can pinch the nerve. CTS commonly results from repetitive hand movements, wrist anatomy, pregnancy, or conditions like diabetes and rheumatoid arthritis. Symptoms include numbness, tingling, and pain in the thumb, index, middle, and part of the ring fingers, often worsening at night. Some people may experience hand weakness or difficulty gripping objects. Early-stage CTS can often be managed with wrist splints, activity modification, and anti-inflammatory medications. In more advanced cases, corticosteroid injections or surgery to release pressure on the median nerve may be necessary. Prompt diagnosis and treatment are important to prevent permanent nerve damage and loss of hand function. Ergonomic changes and proper wrist positioning can help reduce risk and recurrence.
