We reported on 2 operative cases of chronic posterior dislocation of the shoulder.Case 1: A 37-year-old man received a hard blow to his right shoulder in a motor-vehicle accident. The initial physician diagnosed this case as a humeral fracture, and he was treated conservatively for 7 months. After we diagnosed it as a posterior dislocation, a modified McLaughlin procedure was performed. The ROM and JOA scores had improved. Case 2: A 55-year-old man fell down and took a hard blow to his right shoulder. An initial physician diagnosed this case as a humeral fracture, and he was treated conservatively. After we diagnosed him as a posterior dislocation, prosthetic replacement was performed. The ROM had subsequently improved. According to Hawkins, it is necessary for a chronic posterior dislocation to be treated in consideration of the period from injury and cartilage deficit. If the period from initial trauma is short, there are fewer damages to the joint and we can perform a joint preservative and minimally invasive surgery. We chose this operation method in consideration of age and in addition to Hawkins.
