# Traumatic ulna fracture with plastic deformation of the radius in a skeletally mature pregnant female: a case report

## TL;DR

A 20-year-old pregnant woman suffered a rare forearm fracture requiring surgery, with full recovery 16 months later.

## Contribution

Reports a rare case of plastic deformation in a skeletally mature adult with pregnancy-related factors.

## Key findings

- Plastic deformation of the radius complicated an ulna fracture in a pregnant woman.
- Corrective osteotomy of the radius was needed for proper alignment.
- The patient achieved full painless motion and radiographic union after surgery.

## Abstract

A 20-year-old pregnant female presented with an ulna fracture after a crush and bending type injury. Anatomic reduction of her ulna was not possible due to plastic deformation of the radius, requiring a corrective osteotomy of the radius. She is now 16 months out from surgery with full painless range of motion and radiographic union.

Plastic deformation of forearm fractures in adults is a rare phenomenon. It is possible that the patient’s pregnancy contributed to her injury. Patients with uncommon fracture morphology can make operative intervention more complicated and necessitate additional procedures to achieve optimal motion and alignment.
