Common Injuries and Recovery for the Ex-Racehorse

Transitioning a racehorse into a new career can be a rewarding experience, but it often comes with physical challenges. Racehorses are trained for high intensity, repetitive movements that can lead to specific musculoskeletal issues. Understanding the most common injuries these horses face – and how to help them recover is essential for providing a healthy, comfortable, and purposeful second life.

Tendon and Ligament Injuries

Common Issues:

One of the most frequent injuries in racehorses is damage to the superficial digital flexor tendon or suspensory ligament. These injuries may present as swelling, heat, lameness, or in more serious cases as a “bowed” appearance in the leg.

Rehabilitation Plan:

  • Initial box rest and anti-inflammatory treatment
  • Gradual, controlled hand-walking
  • Ultrasound monitoring
  • Shockwave therapy or regenerative treatments like stem cells or PRP
  • Proper support bandaging and therapeutic boots during reconditioning

Sacroiliac issues

Common Issues:

Sacroiliac (SI) joint issues are most common in ex-racehorses due to repetitive strain, leading to symptoms like a “hunter’s bump” (prominent tuber sacrales), hindquarter lameness, poor performance, gait changes e.g. hind limb stiffness, muscle atrophy and behavioral issues like kicking or bucking. 

Rehabilitation Plan:

  • Stall rest is often a first step for severe injury. 
  • Free movement is essential for recovery – increased paddock time and walk in/out stables or a controlled full turn out situation are preferable. Large herd environments are not encouraged until the horse is strong enough to handle herd dynamics.
  • A phased program of controlled exercise to build strength and mobility. 
  • Specific exercises and physiotherapy can support and can help strengthen the SI ligaments. As well as working over poles or cavaletti and slowly building balance and co ordination through proprioception,
  • Medications may be injected directly into the SI joint or surrounding ligaments to reduce inflammation and pain. 

Kissing Spine

Common Issues:

This condition, where the vertebrae are too close together and may touch or “kiss,” is more commonly diagnosed now thanks to improved imaging. It can lead to back pain, behavioral issues, and poor performance.

Rehabilitation Plan:

  • Veterinary diagnosis through X-rays
    Chiropractic adjustments and physiotherapy
    Core strengthening exercises (e.g. carrot stretches, belly lifts)
    Proper saddle fitting to reduce back pressure
  • Surgery (interspinous ligament desmotomy) in severe cases

Hoof Problems

Common Issues:

Racehorses are often kept with low heels and long toes for speed, but this can lead to issues like under-run heels, thin soles, and chronic bruising once they retire.

Rehabilitation Plan:

  • Corrective trimming and shoeing
  • Use of hoof boots during turnout or riding
  • Biotin-rich hoof supplements
  • Regular farrier visits every 4–6 weeks
  • Avoiding excessive hard ground work until hooves strengthen

Gastric Ulcers

Common Issues:

The stress of racing, combined with limited forage and high-concentrate diets, makes ulcers extremely common in ex-racehorses. Symptoms include poor appetite, irritability, weight loss, and girthiness.

Rehabilitation Plan:

  • Transition to a high-forage, low-starch diet
  • Offer frequent small meals with ad lib roughage
  • Use ulcer-preventing supplements (e.g. aloe vera, lecithin)
  • Veterinary scope diagnosis
  • Treatment with ulcer medication

Mental and Emotional Trauma

Common Issues:

Beyond physical issues, some ex-racehorses struggle with anxiety, confusion, or fear in new environments. They may not understand turnout, grooming routines or how to be easily handled. The transition period required from full stable care to larger paddocks needs to be considered as the spatial perception of the horse will need to adjust over time as the horse lets down and starts to adapt to a new routine and environment.

Rehabilitation Plan:

  • Establishing a consistent routine
  • Groundwork to build trust and understanding
  • Exposure to calm herd mates
  • Patience, time, and positive reinforcement
  • Working with experienced retrainers or behaviorists
