inflammation of a tendon sheath caused by calcium deposits, repeated strain or trauma, high levels of blood cholesterol, rheumatoid arthritis, gout, or gonorrhea. In some instances, movement causes a crackling noise over the tendon. Most cases not associated with systemic disease respond to rest. Local injections of corticosteroids may provide relief; surgery is indicated if the condition persists. Also called tendosynovitis .
A digit with a focal fusiform swelling—due to oedema and/or inflammation—of the flexor tendon or tendon sheath which causes a painful lock-snap sensation, leaving the digit in flexion or extension. Trigger finger is most common in women in their sixth decade, and is associated with de Quervain’s disease, carpal tunnel syndrome, tenosynovitis, rheumatoid arthritis, and connective tissue disease
inflammation of the thin synovial lining of a tendon sheath, as distinct from its outer fibrous sheath. It may be caused by mechanical irritation or by bacterial infection.
tenosynovitisinflammation of tendon and synovial sheath
acute simple synovitis traumatic synovitis; due to over-/unaccustomed use causing tendon and synovial sheath inflammation; characterized by pain/crepitus on movement, local swelling and tendon warmth; treated by rest, appropriate padding and strapping, orthoses, shoe advice (especially for tenosynovitis of extensor hallucis longus)
chronic simple synovitis; repetitive strain injury; RSI chronic inflammation of tendon/sheath (due to repetitive overuse), together with subserved muscle weakness/wasting; treated as chronic inflammation; note: cause must be established and resolved to achieve permanent resolution
