A long-standing radial head dislocation, present for 8 years, was successfully treated. The treatment involved open reduction and 3D ulnar osteotomy guided by computer simulation.

Area of Science:

Orthopedic Surgery
Medical Imaging
Biomechanical Engineering

Background:

Radial head dislocation is a common elbow injury.
Delayed treatment of radial head dislocation can lead to chronic pain and dysfunction.
Surgical intervention is often required for chronic or neglected cases.

Observation:

A patient presented with a radial head dislocation that had been present for 8 years.
The chronic nature of the dislocation presented significant surgical challenges.

Findings:

Successful treatment was achieved through open reduction of the radial head.
A 3-dimensional ulnar osteotomy was performed.
Computer-generated templates, based on 3D preoperative simulation, guided the surgical procedure.
