# Open Dislocation of the Scaphoid With an Associated Hamate Fracture and Fourth Metacarpal Fracture

## TL;DR

This paper presents a rare case of open scaphoid dislocation with additional fractures in the wrist and hand.

## Contribution

The novelty lies in the detailed treatment approach for a complex combination of wrist injuries.

## Key findings

- Scaphoid dislocation is rare and often caused by high-energy trauma.
- Concomitant injuries like hamate and metacarpal fractures require combined surgical interventions.
- Repair of the scapholunate ligament is crucial to prevent long-term complications.

## Abstract

Scaphoid dislocation represents a rare injury with only a few case reports and limited case series reported in the literature. The majority of scaphoid dislocations result from a high-energy trauma causing hyperextension and ulnar deviation of the wrist. The severity of a scaphoid dislocation depends on the degree of periscaphoid ligamentous injury as well as the presence of concomitant injuries, such as axial carpal dissociation. The most common complication after a scaphoid dislocation is scapholunate dissociation, which emphasizes the importance of scapholunate ligament repair/reconstruction in these cases. We report a case of an open scaphoid dislocation with the associated injuries of a hamate fracture and fourth metacarpal fracture treated with an open reduction of the scaphoid, open ligamentous repair and augmentation of the involved carpal ligaments, and open reduction internal fixation of both the hamate and the fourth metacarpal fractures.
