Reducing a Shoulder Dislocation Without Sweating. The Davos Technique and its Results. Evaluation of a Nontraumatic, Safe, and Simple Technique for Reducing Anterior Shoulder Dislocations

Abstract

Background: Anterior shoulder dislocation is a well-known injury for people working in emergency departments (EDs). Throughout the years, the focus has been shifted onto more gentle reduction techniques with less risk of iatrogenic injury, fracture displacement, and less pain for the patient. We present the results of one such technique, the Davos reduction maneuver, also known as the Boss-Holzach-Matter technique, as well as its advantages, disadvantages, and a few practical tips.

Discussion: We evaluated, retrospectively, 100 patients presenting with an anteroinferior shoulder dislocation, who were treated in the ED of the university hospital of Geneva, Switzerland, in a time period of 18 months. In every case, the Davos technique was used for shoulder reduction. The detailed technique is described. Successful reduction was achieved in 86 patients. There were no neurological complications. Greater tuberosity fracture malreduction was noted in one case. Eighteen patients received no analgesia. Our results were comparable or superior to other reduction techniques.

Conclusion: We concluded that the Davos technique is an easy, nontraumatic, very well-tolerated, and most of all, safe way to reduce a shoulder. It is complication free and easy to apply, giving reproducible and comparable or superior results to other reduction techniques. At the same time, it is well tolerated by a compliant patient, which makes it an ideal first-time reduction technique for anterior shoulder dislocations.
