![]() ![]() Psoriatic is also a commonly associated autoimmune condition įrequent repetitive movements can cause inflammation of the synovial sheath this is often referred to as repetitive strain injury or overuse syndrome. ![]() This has been shown in an experimental mouse model but has yet to be proven in humans. As the tendon sheath has a sizeable synovial component, there may be an essential role of the tendon sheath in the disease process and the patient's symptoms. Rheumatoid arthritis has a predilection for synovial linings. There is a strong link between rheumatoid arthritis and tenosynovitis, and up to 87% of rheumatoid arthritis patients have radiological features of tenosynovitis on MRI. Non-infective causes include autoimmune, overuse, and idiopathic. Tenosynovitis can be divided into infective and non-infective causes. The tendon sheath has the following functions: Together, the fibrous tunnel and synovial covering form the tendon sheath. Within each tunnel, the tendons are surrounded by a synovial sheath or bursa. Shortly after exiting the carpal tunnel at the wrist, the tendons of flexor digitorium superficialis and profundus muscles cross the palm and enter tunnels formed by the fibrous sheaths on the palmar aspect of each digit. The tendons' intricate arrangement in the hand permits the gripping, grasping, and precise motor function of the hand. The tendon anatomy and relationship to the tendon sheath are well illustrated in the hand. A basic understanding of the tendon anatomy allows the clinician to appreciate the pathophysiology, treatment, and complications. ![]() The condition can affect any tendon in the body surrounded by a sheath but has a predilection for the hand, wrist, and foot. It commonly manifests as pain, swelling, and contractures, depending on the etiology. Tenosynovitis is a broad term describing the inflammation of the fluid-filled synovium within the tendon sheath. ![]()
