Abstract Abstract
Carpal Tunnel Syndrome (CTS) is the most common idiopathic neuropathic compression syndrome in the upper extremity, with a reported prevalence of 2.7% in the general population. Trigger Finger (TF) is a common upper limb disorder characterized by the painful locking of one or more fingers. A review of the literature, and personal experiences of the authors indicates that the occurrence of Trigger Finger after Carpal Tunnel Syndrome surgery is significantly higher in patients with CTS compared to those without CTS, though this increase in incidence has not definitively been linked to the surgery. In most studies, thumb has been the most commonly involved finger in association with CTS; however, in some cases, the third finger was more common. In contrast, when TF occurs alone, the fourth finger is typically the most frequently affected finger with triggering in the fourth one.
