ABSTRACT
Trigger finger, also called stenosing tenosynovitis, can affect any of the digits but most commonly affects the thumb, ring and middle fingers.1 The incidence is greatest in women, with the average age being between 52 and 62 years.2 The great majority of cases involve obstruction of the flexor tendon at the A1 pulley. Trigger finger has been associated with a number of systemic conditions, including amyloidosis, mucopolysaccharidosis and rheumatoid arthritis.3
