# A Rare Case of Intramediastinal Humeral Head Fracture Dislocation Through the Thoracic Inlet

## TL;DR

A rare case of a humeral head fracture dislocation into the mediastinum is reported in a 71-year-old woman following a fall.

## Contribution

This is the second reported case of intramediastinal humeral head fracture dislocation, offering insights into treatment challenges.

## Key findings

- The patient suffered a high-energy trauma leading to intramediastinal dislocation without chest wall injury.
- Thoracic duct rupture occurred, necessitating three surgical interventions for treatment.
- The case highlights the rarity and complexity of managing such injuries.

## Abstract

Intramediastinal fracture dislocation of the humeral head due to a blunt trauma is very rare. It may be accompanied by local and systemic injuries associated with high‐energy trauma. Only one case has been reported in the literature; therefore, an appropriate treatment modality remains unclear. We present a case of a 71‐year‐old woman involved in an accidental fall who sustained an intramediastinal humeral head fracture dislocation through the thoracic inlet, without damaging the chest wall, causing the thoracic duct rupture and requiring three consecutive surgical procedures as treatment.
