Distal radius fracture – Supination underestimates dorsal tilt in distal radius fracture radiographs: a case report

TL;DR

This case report shows that incorrect forearm positioning in X-rays can lead to inaccurate measurements of wrist fractures.

Contribution

It highlights how supination affects dorsal tilt measurements in distal radius fracture radiographs.

Findings

Supination underestimates dorsal tilt in distal radius fracture radiographs.

Correct forearm positioning is crucial for accurate radiographic assessment of wrist fractures.

Abstract

Distal radius fractures are one of the most prevalent fracture types. Dorsal tilt of the articular surface of the distal radius as assessed on the lateral radiograph is often used in determining the correct treatment method. This report seeks to highlight the importance of correct forearm positioning when obtaining distal radius radiographs, and the effects of pronation and supination on dorsal tilt measurements of the radius. It presents a case of a 35-year-old male with a malaligned left-sided distal radius fracture sustained during a sports-related fall.
