Abstract

Objective: The aim of this study was to assess the effectiveness and reproducibility of self-assisted Boss-Holzach-Matter (BHM) technique compared with the Spaso (Sp) method for shoulder dislocation. Methods: We conducted a follow-up at 1 year from the randomization of 60 patients with shoulder dislocation enrolled in the study "Teaching patients to reduce a shoulder dislocation." Half of these patients had been taught the self-assisted technique, whereas the other half had been treated by a physician's manipulative maneuver for reduction. We surveyed all the enrolled patients to describe recurrence rates and reproducibility for both the techniques without supervision as well as the number of emergency visits. Results: In total, 52 patients (age range: 18-44 years) answered the survey from the 60 patients enrolled in the study. The total rate of recurrence was 38.5% (20 patients). For the Sp group, 4 of the 30 patients were lost. There were 9 recurrent patients (30%), and 7 were treated in the emergency department (ED). For the BHM group, 4 of the 30 patients were lost. There were 11 recurrent patients (37%), and 2 were treated in the ED. The difference in self-reduction rates and ED visits for both the groups was statistically significant (p=0.025). Conclusion: Teaching the BHM technique to the patients is effective and reproducible without direct supervision. It can decrease the number of visits to the ED and is a valid option to teach the patients at risk of recurrence when not being able to get immediate help.
