Outcomes of Inferior Shoulder Dislocation at Prof. Dr. IGNG Ngoerah General Hospital: A Case Series

Introduction: Inferior shoulder dislocations also known as "luxatio erecta of the humerus" are uncommon injuries that only account for 0.5-1% of all shoulder dislocations. This case series aimed to present the outcomes of inferior shoulder dislocation in two cases. Case Presentation: We presented two patients with inferior shoulder dislocation. One case was an elderly male who fell from the stairs and another case was a young female who fell from a motorcycle. Both patient's arms were in elevation, full abduction, and external rotation position which is typical for inferior shoulder dislocation. A shoulder x-ray examination was performed to confirm the diagnosis and finding associated injuries. Both patients were managed with closed reduction under general anesthesia and immobilization with collar and cuff. Discussion: The incidence of inferior shoulder dislocation is more common among the elderly. The clinical signs and symptoms were clear, diagnosis can typically be determined from the exam room doorway. The etiology was usually traumatic, such as falling from motorcycles with shoulders touching the ground, which made the acromion pressed up against the humerus neck. It is crucial to do imaging examinations since inferior shoulder dislocation is commonly accompanied by fractures, soft tissue, or neurovascular injuries. The preferred therapy is closed reduction following immobilization with collar cuff as the prognosis is generally favorable. Conclusion: Early close reduction is necessary in inferior shoulder dislocation to avoid further complications and reduce pain. The prognosis is generally favorable. However, the healing process can be significantly influenced by age. Both patients in this case series have good clinical and radiological outcomes after closed reduction under general anesthesia and immobilization with collar and cuff.
