Article PDF File: Page From: 124 To: 128
Article abstract: Introduction & Objective: Shoulder dislocation is one of the most common dislocations of large joints and anterior type is the most common type of it. Inferior shoulder dislocation is a rare type. There are few reported cases about this kind of dislocation so complications and results of it are not fully understood.
Materials & Methods: A 40 year old man who injured in a car accident, has been referred to emergency room. His arm was held in the position of abduction and external rotation. He had refractory hypotension which needed emergent spelenectomy. In the same anesthesia we reduced his shoulder dislocation but the fractured greater tuberosity did not reduced completely to its anatomic position was not normal and also it seemed to be intraarticular and caused joint incongruity; so after several days and after the patient became stable, open reduction and internal fixation of greater tuberosity of humerus were done.
Conclusions: Because of rarity of inferior dislocation of shoulder, we cannot compare inferior shoulder dislocation with anterior shoulder dislocation (which is more common) in their complications and results, but it seems that higher energy trauma is needed to cause inferior dislocation of shoulder and also direction of dislocation of head causes more injury to adjacent soft tissues, so after reduction of shoulder, the chance of anatomic reduction of greater tuberosity of humerus is low in this type and the need for surgery is higher.
