Fractures of the anatomical neck of the humerus are an extremely rare pathological entity in the field of orthopedic surgery. One of the most feared complications associated with anatomical neck fracture of the humerus is avascular necrosis (AVN). The literature does not contain clear, evidence-based guidelines for the surgical management. This case report highlights the case of a 33-year-old male patient who presented with anatomical neck humerus fracture dislocation after a snowboarding accident. Computed tomography showed a comminuted displaced fracture involving the right humeral neck associated with anterior dislocation of the right shoulder. A small bony fragment adjacent to the glenoid posteriorly was also revealed. The patient was treated with open reduction and internal fixation (ORIF). After 3 years of follow-up, the patient is fully recovered with a normal range of motion of his right shoulder joint. The patient did not show any signs of AVN of the humeral head throughout the course of the 3-year follow-up. Anatomical neck fractures of the humerus are uncommon injuries in the literature. Due to the poor vascularization and the absence of attachment to soft tissue, there is a significantly high risk of AVN associated with fractures of the anatomical neck of the humerus. The patient presented in our report was treated with ORIF since it allows preservation of the humeral head.
