Clinical and Imaging Correlates of Radial Styloid Changes in De Quervain's Tenosynovitis: A Cross-Sectional Observational Study.

Introduction: De Quervain's Tenosynovitis is a common musculoskeletal condition affecting the wrist, often associated with pain and functional limitations. While clinical features are well documented, the role of osseous changes in the radial styloid and their impact on symptom severity remain unclear. Aim: The aim of the paper is to evaluate the association between radial styloid changes, pain severity, symptom duration, and clinical outcomes in patients with De Quervain's Tenosynovitis. Materials and Methods: The study involved 32 participants with De Quervain's Tenosynovitis, collecting data on age, symptom duration, and pain severity. Clinical assessments included pain presence, tenderness, swelling, and range of motion restriction. Imaging findings, such as radial styloid abnormalities and tendon sheath inflammation, were analyzed. Predictors of pain severity and symptom duration were assessed using descriptive statistics and multiple regression models. Results: The mean age of participants was 45.84 years (standard deviation (SD) = 11.50), with a mean symptom duration of 26.97 weeks (SD = 15.18). The mean Visual Analog Scale (VAS) score was 4.87 (SD = 2.83). Pain presence was reported in 93.75% of participants. Regression analysis indicated that tendon sheath inflammation and age exhibited trends toward significance in predicting VAS scores (P = 0.095, P = 0.072, respectively). Magnetic resonance imaging signal changes showed near-significance in predicting symptom duration (P = 0.055). No significant correlation was found between symptom duration and pain severity (r = 0.00, P = 0.982). Conclusion: De Quervain's Tenosynovitis is characterized by pain-related symptoms, with structural abnormalities and imaging findings showing variable associations with symptom severity and duration.
