Radius: fracture repair

Contributor(s): Graham Munroe, David G Wilson

Introduction

  • Successful management of radial fractures can be achieved through a number of different modalities depending upon the owner's wishes and financial status, fracture configuration, size of animal and extent of soft tissue injuries.
  • The most common surgical technique is plating via internal fixation.

Uses

  • Repair of simple mid-diaphyseal or metaphyseal radial fractures, usually in foals, yearlings or small adults   Radius: fracture    Radius: fracture 01 - diaphysis - radiograph    Radius: fracture repair 01 - LM radiograph  .

Advantages

  • Treatment of choice for mid-diaphyseal simple fractures in foals or small adults (up to 300 kg bodyweight) with relatively good prognosis for future soundness.
  • An intact caudal cortex improves prognosis.

Disadvantages

  • Expensive.
  • Technically challenging.
  • Significantly poorer results in distal metaphyseal/epiphyseal or comminuted fractures and especially where articular surfaces involved.
  • Poor results in adults (>400 kg).

Prognosis

  • <300 kg:
    • Short oblique/transverse mid-diaphyseal fractures: good for soundness.
    • Fractures of metaphysis: guarded to fair.
    • Fractures of physis/joint surface: guarded to poor.
  • >400 kg: guarded to poor for soundness.
