Unusual Locked Trigger Finger Due to #Tophaceous Infiltration of Wrist Flexor Tendon by William Hau Wuei Huang in BJSTR
Abstract
Tophi can present as a first sign of hyperuricemia but reports on the
involvement of the flexor tendons of the hand is rare. Although
tuberculous tenosynovitis is a more common etiology for swelling over
the wrist, gout must be among the differentials irrespective of
hyperuricemic status. Because of its low frequency, gouty involvement of
the flexor tendons is not often considered in the differential
diagnosis
of tenosynovitis. We report a rare case in which intratendinous tophaceous gout was found within the flexor digitorumsuperficialis
tendon at
the wrist causing patient to have trigger finger like symptoms.
