Triggering of the finger at the wrist due to a leiomyoma arising from the lumbrical muscle of the middle finger

Abstract

suggesting that paediatric trigger thumb is an acquired phenomenon (Shah and Bae, 2012).Although the aetiology of paediatric trigger thumb has not been clearly established, it is likely that there is a multifactorial aetiology with a congenital component, which this case series supports.

Sonographic Evaluation of Trigger Finger at the Wrist and Carpal Tunnel Syndrome Resulting From a Deep Soft Tissue Leiomyoma

“…There have been 2 prior case reports that presented leiomyomas at the wrist, one resulting in triggering of the middle finger at the wrist 4 and the other resulting in carpal tunnel syndrome 5 . Our case is unique in that this individual had both triggering of the finger at the wrist and carpal tunnel syndrome.…”

Leiomyoma in the thumb causing trigger finger

“…It involves the first annular pulley and consists in a blockage or triggering of the finger when moving it from flexion to extension 19 20. Even small tumours, when close to MCP joint areas, can cause trigger finger.…”
