Comparison of radiological results of surgical repair of Rockwood V acromioclavicular dislocation with the modified Endobutton vs. Phemister technique

Abstract

Acromio-clavicular dislocation is one of the most common traumatic injuries of the shoulder and represents 9% of all shoulder girdle injuries. Management is carried out according to Rockwood's classification, with grade IV, V and VI dislocations generally being repaired by surgery. There are several surgical techniques for the repair of grade V dislocation, being the modified Phemister technique the most used, however, new techniques have been proposed such as the use of Endobutton, which has shown excellent clinical and functional results in this type. of injuries. The objective of this article is to compare the radiological results of the treatment of Rockwood V acromioclavicular dislocation by Endobutton versus the modified Phemister technique. The applied methodology was carried out based on a comparative study between the surgical repair of grade V acromio-clavicular dislocation by Endobutton versus the modified Phemister technique, through post-surgical radiological analysis of the coraco-clavicular distance, in patients undergoing these interventions in the Hospital San Francisco de Quito. The modified Phemister technique reflects better post-surgical results than the Endobutton technique; Furthermore, the excessive cost of the latter does not justify its use, since the same or even better results are obtained with the modified Phemister technique. Finally, it is concluded that the Orthopedic surgeon performs the technique that is most familiar, since both are a good option for the repair of Grade V Acromioclavicular Dislocation.
