• A. Fingers held in mild extension / Extension deformity at the involved fingers.
• B. Tenosynovitis of little finger will spread to thumb rather than ring finger.
• C. With involvement of little finger the infection can spread to the index finger.
• D. Treatment is conservative.

Answer 1

The Correct Option is B

Tenosynovitis of the finger is an inflammation of the tendon sheath. Understanding how this condition can spread is crucial for effective management. The correct option here is that tenosynovitis of the little finger will spread to the thumb rather than the ring finger. This occurs due to the anatomical connection between the tendon sheaths of the little finger and the thumb, known as the ulnar and radial bursae connection, which is more medial and proximal than the connections to the ring finger. Treatment of tenosynovitis is not strictly conservative, as it often requires more invasive interventions if conservative management fails. Therefore, recognizing the anatomical pathways is vital in predicting infection spread and planning treatment.
