Hock fracture (tarsal slab fracture)

Overview

## Overview Tarsal slab fractures are articular fractures of the hock, most often involving the central or third tarsal bones. They occur in racehorses and other performance horses from hyperextension or fatigue. Signs include acute hock lameness and effusion. Surgical lag-screw repair is the treatment of choice for displaced articular slabs. ## Causes Acute overload or stress fracture propagation. ## Diagnosis Radiographs, often requiring multiple oblique views. Computed tomography provides detail. ## Treatment Lag-screw fixation for articular slabs. Conservative management for some non-displaced fractures. Prognosis is better with accurate reduction. ## Recovery and Prognosis Fair to good for properly repaired slabs. Osteoarthritis can develop. ## Prevention Training management to reduce fatigue injury.

Signs & Symptoms

acute hock lameness; hock effusion; pain on flexion; radiographic slab fracture
