Teaching Patients How to Reduce a Shoulder Dislocation: A Randomized Clinical Trial Comparing the Boss-Holzach-Matter Self-Assisted Technique and the Spaso Method

This report has been verified by one or more authors of the original publication.

60 patients with an acute anterior shoulder dislocation were randomized to either physician-guided self-reduction using the Boss-Holzach-Matter technique, or to physician-administered reduction using the Spaso technique. Patients were assessed for pain severity experienced during reduction and for the rate of successful reduction. Results demonstrated significantly lower patient-rated pain during reduction using the self-administered Boss-Holzach-Matter technique in comparison to the physician-administered Spaso technique. The rate of successful reduction did not significantly differ between groups.
