# Atypical Fracture of the Scapular Spine: A Case Report

## TL;DR

This case report describes a rare atypical fracture in the scapular spine of an elderly woman on long-term osteoporosis treatment.

## Contribution

The report highlights an extremely rare case of atypical fracture in a non-weight-bearing bone due to long-term bone-modifying agents.

## Key findings

- An atypical scapular spine fracture occurred in a 92-year-old woman on minodronate for 7 years.
- The fracture site remained dislocated after conservative treatment but did not hinder daily activities.
- Atypical fractures in non-weight-bearing bones are exceptionally rare and require further study.

## Abstract

Atypical fractures are gaining attention as a severe potential side effect of long-term treatment with bone-modifying agents (e.g., bisphosphonate and denosumab) for osteoporosis. Most atypical fractures occur in weight-bearing bones; the femur is the most frequent site. Atypical fractures occurring in non-weight-bearing bones are extremely rare. We describe an atypical fracture of the scapular spine in a 92-year-old Japanese woman with osteoporosis who had been treated with minodronate for ~7 years. Although the dislocation of the fracture site remained after conservative treatment, there was no obstacle to her daily life.
