Background: Both stenosing tenosynovitis and Dupuytren's contracture are common conditions encountered in hand surgery. Connections between 2 diseases have been suggested in literature. The purpose of this study was to examine whether there's an association between the 2 processes.
Methods: A retrospective chart review was performed to include all patients seen by a single surgeon between 2014 and 2017 with the diagnosis of either trigger finger or Dupuytren's contracture in the same hand. Patients' demographics, medical history, social and surgical histories are recorded. Univariate and multivariate analysis were conducted.
Results: A cohort of 238 patients was identified. One hundred ninety-two patients were diagnosed with trigger finger. Eighty-nine patients were diagnosed with Dupuytren's contracture. Forty-three patients carried both diagnoses. Median age was 61.6 (56-72). Half were male (50.4%) and 66.8% reported current alcohol intake. Other factors include history of former or current tobacco use (52.9%), diabetes (23.9%), and manual labor (31.1%). In the univariate model, trigger finger, sex, and age were significantly associated with the diagnosis of Dupuytren's contracture, and Dupuytren's contracture and sex were significantly associated with the trigger finger diagnosis. Diabetes, manual labor, use of alcohol and tobacco were not significant. In the multivariate model, age and trigger finger were significantly associated with Dupuytren's contracture.
Conclusions: Significant association between stenosing tenosynovitis and Dupuytren's contracture was identified in our patient cohort. Patients with stenosing tenosynovitis may be at an increased risk of developing Dupuytren's contracture or vice versa.
