Introduction: Inferior dislocation of the shoulder is a rare injury. Some specific complications may occur immediately or during follow-up. We present a rare case of erecta dislocation with a neurological injury. Case presentation: We report a 23-year-old female admitted for erecta dislocation on her right shoulder after sport accident complicated with a fracture of the greater tuberosity and axillary nerve palsy. A closed reduction had been indicated with a reduction of both fracture and dislocation. Functional treatment had been adopted. The neurapraxia had resolved spontaneously. At last outcome, the patient is satisfactory with a full range of motion on her right shoulder. Discussion: Inferior shoulder dislocation leads, usually to tears on soft tissue of the shoulder especially capsular, labral and inferior glenohumeral ligament. Immediate complications are serious such as neurological palsy and vascular problems. Indications depend on reducibility and associated injuries. Conclusion: Neurological complication especially neurapraxia is a serious injury but did not require open reduction and surgical exploration explained by the traction at the point where the axillary nerve passes through the quadrangular space.
