Presence of an intracompartmental septum detected by ultrasound is associated with the failure of ultrasound-guided steroid injection in de Quervain's syndrome.
The purpose of this study was to find clinical or ultrasound characteristics that might predict the failure of conservative treatment in de Quervain's syndrome. A total of 42 ultrasound-guided injections have been performed in 41 patients after clinical and ultrasound examination. Patients were immobilized for 3 weeks with a spica splint cast, and clinically evaluated at 3 and 6 weeks and by phone call at the end of the study. Ultrasound showed a septum between the tendons of the first comportment in 34% of the wrists. At last follow-up (mean 15.6 months after the injection) ten patients (24%) had undergone surgery. When comparing ultrasound and clinical characteristics of the operated and non-operated wrists, we found that patients with a high baseline visual analogue scale, with all positive clinical tests and with a persistent intracompartmental septum, had a significantly higher risk of failure following conservative treatment.
