Acute calcific tendinitis of Flexor Carpi Ulnaris
Acute calcific tendinitis of Flexor Carpi Ulnaris is an unusual, painful, monoarticular, periarticular inflammatory process associated with juxtaarticular deposits of amorphous calcium hydroxyapatite.
CHARACTERISTIC CLINICAL FEATURES AND RADIOLOGIC FINDINGS
ACT of FCU has a high rate of misdiagnosis because of its rare occurrence and its clinical resemblance to other entities with wrist tenderness and swelling. One third of patients with ACT provide an history of trauma.
In most cases, treatment is conservative; it consists of immobilization plus nonsteroidal antiinflammatory drugs or local steroid injections. Results are uniformly good.
Failure to recognize this entity may cause unnecessary investigation and therapy.
Clinical presentation may simulate infection, and the associated periarticular calcifications may be mistaken for gout, pseudogout, or other entities.
