Editing Trigger finger (section)

==Causes==
It is important to distinguish association and causation. The vast majority of trigger digits are [[Idiopathic disease|idiopathic]], meaning there is no known cause. However, recent publications indicate that diabetes and high blood sugar levels increases the risk of developing trigger finger.<ref>{{cite journal | vauthors = Rydberg M, Zimmerman M, Gottsäter A, Eeg-Olofsson K, Dahlin LB | title = High HbA1c Levels Are Associated With Development of Trigger Finger in Type 1 and Type 2 Diabetes: An Observational Register-Based Study From Sweden | journal = Diabetes Care | volume = 45 | issue = 11 | pages = 2669–2674 | date = November 2022 | pmid = 36006612 | doi = 10.2337/dc22-0829 | s2cid = 251809634 }}</ref>

Some speculate that repetitive forceful use of a digit leads to narrowing of the fibrous digital sheath in which it runs,<ref name= "Gor1998">{{cite journal | vauthors = Gorsche R, Wiley JP, Renger R, Brant R, Gemer TY, Sasyniuk TM | title = Prevalence and incidence of stenosing flexor tenosynovitis (trigger finger) in a meat-packing plant | journal = Journal of Occupational and Environmental Medicine | volume = 40 | issue = 6 | pages = 556–560 | date = June 1998 | pmid = 9636936 | doi = 10.1097/00043764-199806000-00008 }}</ref> but there is little scientific data to support this theory.
