007 REDUCTION OF ACUTE ANTERIOR DISLOCATION: A PROSPECTIVE RANDOMIZED COMPARATIVE STUDY COMPARING A NEW TECHNIQUE WITH HIPPOCRATES AND KOCHER METHODS

Abstract

Aim of this prospective, randomized study is to introduce and compare a new technique of reduction of the anterior dislocation of the shoulder with the “Hippocrates” and “Kocher” methods, as far as its efficacy, safety and intensity of the pain felt by the patient during the reduction, are concerned. This is the first reported prospective, randomized comparative study of three reduction techniques of anterior dislocations of the shoulder.

154 patients suffering from acute anterior shoulder dislocation participated in the study. Patients were randomly assigned to one of the three study groups (New, “Hippocrates” and “Kocher”) and underwent reduction of their dislocation performed by residents orthopaedic surgeons.

The groups were statistically comparable (age, male/ female ratio, mechanism of dislocation, mean time interval between injury and first attempt of reduction).

Reduction was achieved with the “Fares” method in 88.6%, with the “Hippocrates” in 72.5% and with the “Kocher” in 68% of the patients. This difference was statistically significant, favoring the new method (p=0.033). The mean duration of the reduction (p=0.000) and the mean reported by the patients VAS with the new method (p=0.000) were also statistically significantly lower than those of the other methods. No complications were noted in any group.

The new method seems to be more effective, faster and less painful method of reduction of the anterior shoulder dislocation, when compared with the “Hippocrates” and the “Kocher” methods. It is easily performed by only one physician and it is not more morbid that the other two methods.
