What is a primary cause of tenosynovitis?

• A. Repeatedly extending the hand
• B. Forceful gripping of the hand
• C. Holding the arm away from the body
• D. Bending the fingers independently

Answer: (B)

Tenosynovitis is primarily caused by repetitive motion or overuse of the tendons, which can lead to inflammation of the tendon sheath. Forceful gripping of the hand is a common activity that puts significant strain on the flexor tendons in the hand and wrist. When these tendons are subjected to repetitive or forceful stress, it can result in irritation and inflammation, which is characteristic of tenosynovitis. This inflammatory response can cause pain, stiffness, and limited mobility in the affected area. Other options may involve movements that could lead to discomfort or strain, but they do not specifically correlate with the primary mechanism of injury seen in tenosynovitis. Repeatedly extending the hand and bending the fingers independently might lead to issues primarily related to strain or fatigue but are not as directly linked to tenosynovitis as forceful gripping is. Holding the arm away from the body can contribute to musculoskeletal issues, but it does not specifically cause the inflammation associated with tenosynovitis in the same way that vigorous gripping does.
