What is the inflammation of the synovial sheath surrounding a tendon called?

• A. Fasciitis
• B. Tendinitis
• C. Tenosynovitis
• D. Ectopic Calcification

Answer: (C)

The inflammation of the synovial sheath surrounding a tendon is referred to as tenosynovitis. This condition occurs when the synovial lining, which produces fluid to lubricate the tendon and facilitate smooth movement, becomes inflamed. This inflammation can lead to pain, swelling, and difficulty moving the affected tendon.

Tenosynovitis is specifically characterized by the involvement of the synovial sheath, distinguishing it from other conditions such as tendinitis, which generally refers to the inflammation of the tendon itself rather than the sheath. Fasciitis involves inflammation of the fascia, a connective tissue structure, while ectopic calcification refers to the abnormal deposition of calcium salts in tissues and is unrelated to tendon sheath inflammation. Understanding these distinctions is crucial in the field of athletic training, as accurately identifying conditions allows for appropriate treatment and management strategies.
