Summary

We report a case of a 64-year-old woman who developed a 4-parts shoulder fracture-dislocation with peripheral nerve injury by the displaced fragment, during abaloparatide treatment. Following shoulder hemiarthroplasty, bone union at the greater tuberosity was achieved on postoperative day 16, with remodelling completed at 6 months postoperatively. This course was exceptionally favourable. Factors potentially contributing to the early bone union progression may include the coincidental administration of abaloparatide prior to trauma and the presence of peripheral nerve injury.
