As shoulder joint stability is mainly provided by muscles and connective tissue, it has a wide range of movement and is the joint where dislocation is most often seen due to frequent exposure to trauma. Anterior shoulder dislocation is seen most often at the rate of 95% and posterior dislocation at rates of 4–5%. Inferior shoulder dislocation is seen rarely and has been determined in literature as 0.5% of all shoulder dislocations. Following the excessive abduction of the arm, the neck of the humerus striking the acromion as a lever results in the dislocation of the head of the arm to the inferior glenoid fossa. In literature, 80% of inferior shoulder dislocations are determined as accompanied by tuberculum majus fracture or rotator cuff rupture, 60% by neurological injury and 3.3% by a vascular pathology. In this study, two cases of inferior shoulder dislocation are discussed in the light of the information in the literature.
