Misconceptions about trigger finger: a scoping review. Definition, pathophysiology, site of lesion, etiology. Trigger finger solving a maze

Abstract

Trigger finger (TF) is a disorder characterized by snapping or locking a finger. It has a prevalence of greater than 3% in the general population; however, this estimate could be increased to 5% up to 20% in diabetic patients. Some unreal ambiguity about definition, pathophysiology, site of lesion, and etiology are found among researchers and clinicians, leading to a lack of understanding of all aspects of the disease and improper management as many clinicians proceed to anti-inflammatory medications or steroids injection without in-depth patient evaluation. Original articles cited up to 2022, found through a Google search using the specified keywords, have been used in this review. Close-access articles were accessed through our researcher account with the Egyptian Knowledge Bank. In this review, we will focus on pathophysiology to present all possible findings and etiology to represent all risk factors and associated diseases to assess and confirm a diagnosis and the exact location of pathology hence better treatment modalities and reducing the recurrence of the pathology.
