Abstract :Objective: To investigate ultrasonographic (US), color Doppler ultrasonographic (CDUS), and strain elastography (SEL) characteristics of Dupuytren\\\'s disease (DD) and assess their relationship with clinical findings and lesion morphology. Methods: A total of 226 patients (153 males, 73 females; mean age: 61.5 ± 9.9 years) and 226 lesions were retrospectively analyzed. Lesions were evaluated using B-mode US, CDUS, and SEL for echogenicity, morphology, dimensions, vascularity, stiffness, and anatomical relationships. Flexion deformity and extension of flexor tendons and/or muscular structures were recorded. Statistical comparisons were performed using chi-square, Mann-Whitney U, and Spearman correlation tests. Results: Lesions were most frequently located in the 4th (74.3%) and 5th (23.9%) finger. Cord-like morphology was observed in 62.8%, and 83.6% were hypoechoic. Flexion deformity was detected in 42.9% of cases and was significantly more frequent in lesions with tendon and/or muscular extension (81.3% vs. 0%; p < 0.001). The deformity was also more common in cord-like than nodular lesions (66.2% vs. 3.6%, p < 0.001). Iso-hyperechoic lesions were more likely to be associated with deformity compared to hypoechoic ones (59.5% vs. 39.7%, p = 0.026). In SEL, 52.7% of lesions were stiff, 41.2% moderate, and 6.2% soft. Lesions with deformity had significantly greater anterior-posterior (AP) diameter (p = 0.001). A moderate correlation existed between transverse and AP size (ρ = 0.631, p < 0.001). Conclusion: Flexion deformity in DD is strongly associated with tendon/muscular extension and lesion morphology. US and SEL parameters offer significant value in clinical evaluation, enabling early identification of severe disease and aiding therapeutic planning.
