Abstract
Objectives:
De Quervain’s tenosynovitis is a common wrist pathology affecting the first extensor compartment. A known etiological factor is a history of distal radius fractures, which alter wrist anatomy. This study hypothesizes that morphological variations in the distal radius, even in the absence of fracture history, may contribute to the development of De Quervain’s tenosynovitis.

Methods:
The study included 30 patients treated surgically for De Quervain’s tenosynovitis (study group) and 30 healthy individuals (control group). The exclusion criteria were a history of wrist fractures, anatomical variations, wrist tumors, or deformities. Radiographic measurements of radial inclination, radial shortening, and volar tilt were performed for both groups and statistically compared to evaluate differences in distal radius morphology.

Results:
The study group (24 females, 80%; 6 males, 20%) had a mean age of 51.2 years (30–70), with mean values of 24.1° for radial inclination, 12.2 mm for radial shortening, and 15.4° for volar tilt. The control group (20 females, 67%; 10 males, 33%) had a mean age of 53.1 years (30–70), with respective values of 24.4°, 11.9 mm, and 15.7°. Statistical analysis revealed no significant differences between the groups for radial inclination (p = 0.857), radial shortening (p = 0.351), or volar tilt (p = 0.837).

Conclusions:
While distal radius fractures are associated with De Quervain’s tenosynovitis, this study found no significant correlation between distal radius morphology and the condition in patients without fracture history.
