Ultrasonographic Evaluation of the Prevalence of an Intracompartmental Septum in Patients With de Quervain's Disease.


It has been reported that more patients with de Quervain's disease who had undergone surgical treatment had a septated dorsal compartment than did normal cadavers. The purpose of this study was to sonographically evaluate the prevalence of an intracompartmental septum in patients with de Quervain's disease and to compare the prevalence between groups categorized by sex, age, and peripartum status. The authors performed an ultrasonographic examination of 112 wrists from 103 patients with de Quervain's disease. The prevalence of a septum-like structure in the first compartment was compared between men and women, between older (≥40 years) and younger (≤39 years) patients, and between pregnant or lactating women and other patients. The prevalence of intracompartmental septum in patients with de Quervain's disease was 61.6% (69 of 112). Of the 69 wrists with an intracompartmental septum-like structure, 53 showed this structure completely through the level of the radial styloid, and 16 showed it partially on the level of the distal radial styloid. There was no significant difference between any 2 groups categorized by the patients' demographics. The prevalence of intracompartmental septation in the patients with de Quervain's disease was higher than the previously reported prevalence in cadavers and lower than that of patients who underwent surgery. This result was consistent with a previous report that patients with a septated dorsal compartment may be more at risk of contracting de Quervain's disease and more prone to failure of nonoperative treatment.
