Effects of Sono-feedback during aspiration of Baker's cysts: A controlled clinical trial.

Objective: To determine whether (diagnostic and interventional) ultrasound imaging can be used to provide visual feedback affecting treatment outcome (pain and disability).

Design: Controlled clinical trial.

Subjects: A total of 52 patients with (ultrasonographically confirmed) symptomatic Baker's cysts were enrolled.

Forearm bone mineral density measurements in thoracic outlet syndrome.

Denervation of sensory and sympathetic nerve fibers and reduced blood flow result in decreased bone mineral density (BMD). In this study, we aim to detect the effect of compression of brachial plexus and subclavian vessels on the forearm BMD in patients with thoraric outlet syndrome (TOS). Twenty-three patients with TOS (17 females and 6 males) were enrolled in the study.
