Factors influencing surgical treatment of De Quervain's tendinopathy: A retrospective cross-sectional observational study.

Background: The literature surrounding how different patient, sociodemographic, and anatomical factors influence surgical treatment of De Quervain's tendinopathy (DQT) is limited. Purpose: We hypothesised that different patient, anatomical, or sociodemographic factors influence the management of DQT with regard to non-operative vs. surgical management. Methods: This retrospective cross-sectional study reviewed 155 cases of patients with DQT seen over a 10 year period. Patient-specific factors included age, gender, hand affected, dominant hand, steroid injection given and mean number of injections. Sociodemographic factors included ethnicity, employment, and deprivation, were measured using deprivation quintiles through The Index of Multiple Deprivation. Anatomical factors included the presence of subcompartmentalization, number of APL and EPB tendon slips, tendon thickening, exudative tenosynovitis, hypervascularization, and the presence of a sheath ganglion Patients were categorized into either non-operative or surgical cohort. Bivariate analysis was used to compare factors between the cohorts, and significant factors (p < 0.05) were included in the logistic regression model, used to predict factors influencing surgical management. Results: Bivariate analysis detected a significant difference in the mean number of steroids given between the non-operative and surgical cohort (p = 0.001) patient factors. For sociodemographic factors, a significant difference was found between deprivation quintiles (p = 0.02). From the anatomical factors, the surgical cohort had more patients with multiple APL tendon slips (p = 0.02) and the presence of a tendon ganglion sheath ganglion (p = 0.02). For patient and sociodemographic factors, logistic regression identified that the number of steroids (per patient) and being in deprivation quintile 4 were associated with surgical treatment. For anatomical factors, multiple APL tendon slips and the presence of a tendon sheath ganglion were associated with the surgical treatment. Conclusion: This study suggests that several factors are associated with the need for surgical treatment of DQT, including the number of steroid injections received, social deprivation, and anatomical factors, such as the presence of multiple tendon slips and a tendon sheath ganglion. Our findings add to the growing body of literature exploring factors that may influence treatment pathways for patients with DQT.
