Dorsal Perilunate Dislocation Coupled With a Distal Radius Fracture: A Report of a Rare Case

TL;DR

This paper reports a rare case of a wrist injury involving both a dorsal perilunate dislocation and a distal radius fracture.

Contribution

The novelty lies in documenting and analyzing the combined occurrence of two rare wrist injuries in a single case.

Findings

Dorsal perilunate dislocation combined with a distal radius fracture is a rare injury pattern.

Objective post-operative outcomes are crucial for assessing recovery in such complex injuries.

The report provides insights into diagnosis and treatment approaches for this uncommon condition.

Abstract

High-energy traumatic injuries to the wrist have been reported in the literature, which may result in isolated perilunate dislocations or distal radius fractures (DRFs). Dorsal perilunate dislocations are reported to be more common compared to volar dislocations. The concurrent presentation of a dorsal perilunate dislocation with a DRF has been rarely reported. Objective post-operative outcomes of this injury pattern, such as active motion, sensation, and function, are important with follow-up because of the complexity of this condition.

The purpose of this report is to present the clinical presentation, the radiographic evaluation, and the approach used in the diagnosis and treatment of this uncommon, combined injury.
