Glenoumeral dislocation: a prospective randomized study comparing spazo and kocher maneuvers.

OBJECTIVE

To evaluate and to compare the Spaso and Kocher reduction maneuvers in terms of efficiency, time of reduction, facileness, pain, discomfort to the patient, complications and risks, besides promoting the comparison between the two maneuvers, aiming to ground the emergency conduct.

METHODS

A prospective study with 105 patients with acute shoulder dislocations were enrolled in the study between February 2011 and September 2012. The patients were randomized into two groups and they were submitted to the reduction of dislocation using the Spaso maneuver (group A) or the Kocher technique (group B) by first, second or third-year orthopedic surgery residents from our service. The results were evaluated and compared.

RESULTS

There was no statistically significant difference between the two groups in terms of age, gender, timing of reduction, number of precedent episodes and complications after reduction. However, reduction was achieved in more cases using the Spaso method than it was among the Kocher group, as well as the mean duration of the reduction maneuver and discomfort were shorter in the group A patients.

CONCLUSIONS

Both methods presented good results in terms of dislocation reduction and low complications rates. Nevertheless, the Spaso maneuver was more efficient, fast and easily applicable in comparison with Kocher's method. Level of Evidence I, Therapeutic.
