Lateral condyle nondisplaced fractures

Introduction

Nondisplaced fractures can be complete or incomplete. Both conditions present with lameness and joint effusion. The nature of the fracture is confirmed with radiographs.
Lateral nondisplaced fractures most commonly occur in the forelimb but can also occur in the hind limb.
Bilateral fractures have been diagnosed in Standardbred horses.

Complete and incomplete lateral condylar fracture

Imaging

A complete set of radiographs of the metacarpophalangeal joint is made, including

  • Lateral-medial view
  • Dorsopalmar view
  • Both oblique views
  • 125° dorsopalmar skyline view (as illustrated).

This x-ray shows a complete fracture.

Complete lateral condylar fracture

This x-ray shows an incomplete fracture.

Mechanism of the injury

These injuries occur as a result of cyclic trauma associated with racing.
Warmblood sportshorses are also prone to these type of fractures. Again a repetitive cycling trauma is the thought to be responsible for these fractures.
