The purpose of this study was to evaluate the effect of McLaughlin's method on Patients older than 75 years old and clarify the clinical findings of older patients and young patients less than 55 years old. Older patients were evaluated according to the JOA score, range of motion and muscle strength. Furthermore, the JOA score, range of motion and muscle strength were compared between the two groups. The JOA score of the older patients had improved significantly three months after surgery. The characteristic factor of older patients was weakness of shoulder muscle strength in the early stages after surgery. But muscle strength was recovered completely 12 months after surgery. We considered that McLaughlin's method was effective for older patients.
