Trigger Finger Location and Association of Comorbidities.

Trigger finger is a common cause of hand pain in the adult population. Studies in the past have suggested that ring finger and thumb are the most prevalent trigger fingers. Risk factors, such as diabetes and hypothyroidism, have been reportedly linked to trigger fingers. This observational prospective study was carried out to identify the most commonly affected trigger finger and observe associated comorbidities. At a single clinical site, a total of 46 patients with 54 trigger fingers on 49 hands were identified over a 7-week period. Ring finger, thumb, and long finger were observed to be the most frequent trigger fingers. No strong association between trigger finger and comorbidities, such as diabetes or hypothyroidism was observed.
