Ringbone is a common and often debilitating condition affecting horses, characterized by inflammation and degenerative changes in the coffin joint. This condition can significantly impact a horse’s mobility and performance, making it crucial for owners and equine professionals to understand its causes, symptoms, and treatment options.
Understanding Ringbone
Ringbone, also known as “high ringbone” or “low ringbone,” is a degenerative joint disease that primarily affects the coffin joint, located at the bottom of the horse’s pastern. This joint connects the pedal bone (third phalanx) to the pastern bone.
Types of Ringbone
There are two main types of ringbone:
High ringbone affects the proximal interphalangeal joint (PIP), situated above the coffin joint.
Low ringbone, the more common type, directly impacts the coffin joint.
The severity of ringbone can vary greatly, ranging from mild lameness to severe pain and restricted movement. Early diagnosis and intervention are essential to managing the condition and preserving the horse’s long-term soundness.
How To Treat Ringbone In Horses
Ringbone, a debilitating condition affecting horses, is characterized by degenerative joint disease in the coffin joint (pastern joint) and the navicular bone.

Understanding Ringbone
Ringbone, also known as “navicular disease,” is a complex condition that can significantly impact a horse’s mobility and athletic performance. It primarily affects the navicular bone, a small, triangular bone located on the inside of the hoof, and the surrounding structures, including the coffin joint.
Causes of Ringbone
The exact causes of ringbone are multifaceted and often involve a combination of factors. Some contributing factors include:
- Genetics: Certain breeds, such as Thoroughbreds, Quarter Horses, and Arabians, may have a predisposition to ringbone.
- Conformation: Horses with certain conformational traits, such as upright pasterns or long, sloping pasterns, are more susceptible.
- Overuse and Trauma: Excessive stress on the navicular bone, often associated with intense training or strenuous activities, can contribute to its degeneration.
- Poor Farriery: Improper shoeing practices can exacerbate the condition by placing undue pressure on the navicular bone.
- Other Factors: Nutritional deficiencies, poor hoof care, and underlying metabolic disorders may also play a role.
Symptoms of Ringbone
Recognizing the early signs of ringbone is crucial for timely intervention. Common symptoms include:
- Lameness: Initially, lameness may be intermittent and mild, but it can progress to a more consistent and severe gait abnormality.
- Heat and Swelling: The affected area, particularly the pastern joint and navicular bone, may exhibit increased heat and swelling.
- Digital Pulses: A decrease in the strength of the digital pulses, which are felt on the horse’s leg below the fetlock joint, can indicate a problem with blood flow to the hoof.
- Sensitivity to Touch: The horse may be sensitive to touch or pressure on the pastern joint and navicular bone.
- Difficulty with Movement: The horse may experience difficulty with turning, rising, or performing other maneuvers that require flexion of the pastern joint.
Diagnosis and Treatment
Diagnosing ringbone involves a thorough examination by a veterinarian, including a physical assessment, lameness evaluation, and diagnostic imaging techniques.
Diagnostic Techniques
- Physical Examination: A veterinarian will carefully examine the horse’s legs, focusing on the pastern joint and navicular bone for any signs of swelling, heat, or tenderness.
- Lameness Evaluation: The veterinarian will observe the horse’s gait and movement patterns to assess the severity and location of lameness.
- Radiographs (X-rays): X-rays are essential for visualizing the navicular bone, coffin joint, and surrounding structures. They can reveal degenerative changes, bone spurs, and other abnormalities.
- Ultrasound: Ultrasound imaging can provide a more detailed view of soft tissues, such as ligaments and tendons, which may be affected by ringbone.
- Nuclear Scintigraphy: This imaging technique uses a radioactive tracer to highlight areas of increased bone activity, which can indicate inflammation or degeneration.
Treatment Options
Treatment for ringbone aims to alleviate pain, reduce inflammation, and improve joint function. The specific approach will depend on the severity of the condition and the individual horse’s needs. (See Also: How Did Horses Survive Without Hoof Trimming)
Conservative Management
- Rest: Allowing the horse adequate rest is crucial for healing and reducing stress on the affected joint.
- Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) can effectively manage pain and inflammation.
- Controlled Exercise: Gradual and controlled exercise, such as walking or lunging, can help maintain joint mobility and muscle strength.
- Farriery Modifications: A qualified farrier can adjust shoeing practices to minimize pressure on the navicular bone and support the hoof structure.
- Supportive Therapies: Therapies such as therapeutic ultrasound, laser therapy, or acupuncture may provide additional pain relief and promote healing.
Surgical Interventions
In more severe cases, surgical interventions may be necessary to address the underlying joint pathology. Some common surgical procedures include:
- Navicular Neurectomy: This procedure involves severing the nerve that supplies sensation to the navicular bone, reducing pain signals.
- Deep Digital Flexor Tendon Lengthening: This surgery involves lengthening the deep digital flexor tendon, which can alleviate pressure on the navicular bone.
- Coffin Joint Fusion: In advanced cases, fusion of the coffin joint may be considered to stabilize the joint and prevent further degeneration.
Living with Ringbone
Managing ringbone effectively requires a long-term commitment to providing appropriate care and support for the horse.
Long-Term Management
- Continued Rest and Exercise: Maintaining a balanced program of rest and controlled exercise is essential for preventing further joint damage and maintaining mobility.
- Pain Management: Ongoing pain management strategies, such as NSAIDs or alternative therapies, may be necessary to ensure the horse’s comfort.
- Regular Farriery: Regular farrier appointments are crucial for monitoring hoof health, making adjustments to shoeing practices, and providing appropriate support for the navicular bone.
- Nutritional Support: Providing a balanced diet that meets the horse’s nutritional needs can support joint health and overall well-being.
- Monitoring and Adjustment: Regular veterinary checkups are essential for monitoring the horse’s condition, adjusting treatment plans as needed, and addressing any new or worsening symptoms.
Key Points and Recap
Ringbone is a complex and challenging condition that can significantly impact a horse’s life. Early detection, prompt diagnosis, and a comprehensive treatment plan are crucial for managing the condition effectively. While there is no cure for ringbone, a combination of conservative management strategies, such as rest, pain relief, and farriery modifications, can help alleviate symptoms, improve joint function, and enhance the horse’s quality of life. In more severe cases, surgical interventions may be necessary to address underlying joint pathology. Long-term management involves a commitment to ongoing care, including pain management, regular veterinary checkups, and a balanced program of rest and exercise.
Frequently Asked Questions About Ringbone in Horses
What is ringbone in horses?
Ringbone is a degenerative joint disease that affects the coffin joint (the joint at the back of the horse’s pastern) and the navicular bone. It causes inflammation, pain, and lameness. There are two types of ringbone: high ringbone, which affects the coffin joint, and low ringbone, which affects the navicular bone.
What are the symptoms of ringbone in horses?
Common symptoms include lameness, particularly after exercise, heat and swelling in the affected area, a shortened stride, and difficulty moving uphill. In advanced cases, the horse may become reluctant to move or stand for long periods.
How is ringbone diagnosed in horses?
A veterinarian will diagnose ringbone by performing a physical examination, palpating the joint, and observing the horse’s gait. X-rays are often used to confirm the diagnosis and assess the severity of the condition. (See Also: Do Wolves Eat Horses)
What are the treatment options for ringbone in horses?
Treatment for ringbone depends on the severity of the disease and the horse’s individual needs. Options may include rest, anti-inflammatory medications, joint injections, supportive bandages, and corrective shoeing. In some cases, surgery may be necessary to alleviate pain and improve mobility.
