# Intra-pulmonary migration of a clavicle osteosynthesis pin: a case report

## TL;DR

A 61-year-old man had a Kirschner pin from a clavicle fracture migrate into his lung 25 years after treatment, highlighting the long-term risks of such implants.

## Contribution

This case report highlights the rare but serious complication of intra-pulmonary migration of a clavicle osteosynthesis pin.

## Key findings

- A Kirschner pin used for clavicle fracture fixation migrated into the lung 25 years post-surgery.
- Long-term follow-up is essential for patients with osteosynthesis pins to prevent life-threatening complications.

## Abstract

Fractures of the clavicle are common injuries, which often require reduction and internal fixation. Although Kirschner pins have been commonly used to treat these fractures with good results, migration of these devices may result in severe internal lesions.

We report herein the case of 61-year-old man, who presented for intrapulmonary migration of a Kirschner pin, 25 years after closed reduction and fixation of a clavicle fracture.

Migration of an osteosynthesis pin can be lethal. Patients with osteosynthesis pins, should have a regular follow, until the removal of the wires.
