How Is Tenosynovitis Formed?

　　The tendon sheath is a double-layered, tubular, closed synovial membrane structure enveloping tendons, serving as a protective synovial sheath for the tendons. In the human body, there are two primary locations where tendon sheaths occur: the common tendon sheath for the abductor pollicis longus and extensor pollicis brevis muscles at the distal end of the radius (wrist), and the tendon sheath for the flexor pollicis longus muscle at the base of the first metacarpal bone. So, how does tenosynovitis develop?

　　How Tenosynovitis Develops

　　Tenosynovitis may arise from trauma, local irritation, or other causes, leading to localized edema and ecchymosis, which in turn cause joint injury. Prolonged immobility can result in adhesions and fibroblastic proliferation, triggering inflammatory changes and ultimately tenosynovitis. Generally, if hand or wrist joint problems arise, prompt medical evaluation is essential to prevent subsequent complications. Cold weather slows circulation; thus, when performing tasks requiring wrist movement under such conditions, it is crucial to maintain warmth and apply local heat therapy to promote blood flow.

　　Tenosynovitis can be treated through conservative (non-surgical) management, surgical intervention, or other modalities. For patients with mild symptoms, conservative treatment often yields excellent results. For instance, after washing hands with warm water, patients may perform gentle self-massage. Additionally, daily rotational movements of the hand and wrist can effectively enhance local muscular circulation, thereby alleviating symptoms.

　　In daily diet, avoid spicy and irritating foods, and instead consume protein- and calcium-rich foods. We hope this information proves helpful to you.
