Trigger Wrist

Abstract

Trigger wrist is a relatively rare phenomenon. The pathological entities to which the term trigger wrist is applied are not well defined in the literature. We present three cases of trigger wrist as a result of flexor tendon pathology, review the literature and discuss the use of the term "trigger wrist".

Trigger finger at wrist caused by degenerative changes of the flexor tendon sheath and carpal tunnel syndrome: a case report

“…It is a triggering phenomenon of the fingers with the triggering point of the flexor tendons at the transverse carpal ligament. In literature, it is also known as ‘trigger wrist’ [2–8]. However, this may be confused with clicking, snapping or crepitus of the wrist during wrist motion.…”

“…Carpal tunnel syndrome is almost inevitably associated with this condition in most of the reported cases [2–8,11,13]. During physical examination, flexor tendon triggering at the carpal tunnel should be looked for.…”

“…Carpal tunnel release was done in all reported cases for associated carpal tunnel syndrome [2–8,11,13]. Excision of the tumour or the anomalous muscle belly is required if present.…”

Acute true trigger wrist following partial extensor carpi radialis brevis tendon rupture

“…The previous reported true trigger wrists were produced by the abnormality in either tendon [2][3][4][5], ligament [7][8][9] or carpal bone [10][11][12]. True trigger wrist originated from the injury of extensor tendon is rare with only two prior case reports [2,3].…”

A Child with Trigger Wrist Caused by Finger Flexion and Extension: A Case Report

“…In this patient, the ganglion could have been caused by excessive Japanese drum training. With regard to age, there have been many reports of trigger wrist in middleaged and elderly patients [2,5]. However, only two cases of trigger wrist in patients younger than 10 years of age (Table 1), including this patient [4], have been described.…”
