Patient Data

Age: 30
Gender: Female

Humeral head is inferiorly dislocated. No fracture identified. Note humeral alignment parallel to the chest wall. 

Post reduction


Normal glenohumeral joint alignment on post reduction x-rays. Small Hill-Sachs lesion anteriorly. 

Case Discussion

Inferior shoulder dislocations are rare when compared to anterior, and even posterior shoulder dislocations. 

This case is a little unusual in that it lacks the classic overhead fixed abduction deformity, although this appearance has been reported in the literature 1
