【Medical Guide】Treating Dog Joint Dislocation

Joint dislocation in dogs is a condition where the articular surfaces of a joint are no longer in their normal alignment, typically caused by external force or pathological factors. This can range from a partial dislocation (subluxation) to a complete dislocation (luxation). Commonly affected joints include the hip, patella (kneecap), elbow, and shoulder. This guide provides comprehensive information on recognizing, treating, and managing this condition in your canine companion.

I. Affected Dogs: Any dog breed and age can experience joint dislocation, although certain breeds are predisposed due to genetic factors or anatomical structures. Smaller breeds, for example, are more prone to patellar luxation.

II. Causes of Dog Joint Dislocation:

Trauma: The most frequent cause is a direct, forceful impact, such as a fall, collision with an object, or a forceful twisting motion. This is especially prevalent in active dogs or those involved in high-impact activities.

Congenital Defects: Some dogs are born with joint instability, making them more susceptible to dislocation. This is often genetic and prevalent in specific breeds. Patellar luxation is a prime example of a congenital defect.

Developmental Abnormalities: Improper growth and development can lead to weaker joints, increasing the risk of dislocation. Nutritional deficiencies or growth disorders can contribute to this.

Underlying Diseases: Certain medical conditions, such as hip dysplasia or ligament laxity, can weaken joints and make them more prone to dislocation.

III. Symptoms of Dog Joint Dislocation:

Recognizing the signs of joint dislocation is crucial for prompt treatment. Symptoms can vary depending on the severity and location of the dislocation:

Joint Deformity: Visible changes in the shape of the affected joint, such as a noticeable bulge or depression where it shouldn’t be.

Abnormal Fixation: The joint may be locked in an unnatural position due to the misalignment and the tension of surrounding muscles and ligaments.

Swelling and Inflammation: Significant trauma often results in swelling, bruising, and inflammation around the joint, indicating soft tissue damage.

Altered Limb Posture: The leg might be held inward (adducted), outward (abducted), bent abnormally, or extended unnaturally.

Limp or Lameness: Pain and discomfort will cause your dog to limp, possibly refusing to bear weight on the affected leg. The severity of lameness varies with the severity of the dislocation. Subluxations might cause only intermittent lameness.

Pain and Sensitivity: The dog may exhibit signs of pain upon palpation (touching) of the affected joint. They may whine, cry out, or bite if the area is touched.

Muscle Atrophy: Over time, disuse of the affected limb due to pain and limited mobility can lead to muscle wasting.

IV. Treatment of Dog Joint Dislocation:

Treatment options depend on the severity of the dislocation, the affected joint, and the presence of any associated injuries (e.g., ligament tears). The primary treatment goals are to:

1. Reduction (Repositioning): This involves carefully realigning the dislocated bones back into their normal anatomical position. This is often done under general anesthesia to minimize pain and ensure the dog remains still.

2. Immobilization: After reduction, the joint needs to be stabilized to prevent redislocation. This is typically achieved through:

Splints and Bandages: Provides external support to keep the joint immobile.

Casts: Offers more rigid immobilization.

External Fixators: Used for more complex fractures or dislocations requiring more robust stabilization.

3. Post-Reduction Care and Rehabilitation: This critical phase aims to promote healing and regain full joint function. It typically includes:

Pain Management: Analgesics (pain relievers) and anti-inflammatory medications are crucial to manage discomfort and reduce inflammation.

Rest and Restricted Activity: Strict confinement and limited activity are vital to allow the joint to heal properly. This might involve crate rest for several weeks.

Physical Therapy: Once the initial healing phase is complete, physical therapy might be recommended to improve range of motion, muscle strength, and overall joint function. This could involve exercises and hydrotherapy.

A. Conservative Treatment (Non-Surgical):

This approach is suitable for mild subluxations or minor luxations, especially when there is no associated ligament damage. It involves manual manipulation under anesthesia to reduce the dislocation, followed by immobilization with splints, bandages, or casts for a period determined by the veterinarian.

B. Surgical Treatment:

Surgical intervention becomes necessary in cases of severe dislocations, recurrent dislocations, associated ligament tears, or complex fractures. Surgical techniques may include:

Open Reduction: A surgical incision allows direct visualization of the joint to facilitate accurate repositioning and repair of damaged structures like ligaments or tendons.

Internal Fixation: Metal pins, screws, or plates may be used to stabilize the joint and prevent redislocation.

Ligament Repair: If ligaments are torn, they may be surgically repaired to enhance joint stability.

Arthroplasty (Joint Replacement): In severe cases of irreparable joint damage, joint replacement surgery might be considered as a last resort.

Osteotomy: This surgical procedure involves cutting and reshaping the bone to improve joint alignment and stability. This is often used in cases of patellar luxation.

V. Post-Operative Care and Long-Term Management:

Regardless of the treatment method, post-operative care is crucial for successful recovery. This involves:

Pain Management: Continue pain medications as prescribed by the veterinarian.

Strict Rest: Adhere strictly to the veterinarian’s recommendations regarding rest and activity restrictions.

Regular Veterinary Check-ups: Attend all scheduled follow-up appointments for monitoring progress and adjustment of treatment if necessary.

Physical Therapy: Engage in recommended physical therapy exercises as directed by your veterinarian or a qualified physical therapist.

Nutritional Support: Ensure your dog receives a balanced diet to support healing and muscle growth. Supplements, such as glucosamine and chondroitin, may be beneficial.

VI. Prevention:

While not all dislocations are preventable, some measures can reduce the risk:

Maintain a Healthy Weight: Obesity puts extra stress on joints, increasing the risk of injury.

Provide Regular Exercise: Moderate exercise strengthens muscles and supports joint stability, but avoid high-impact activities if your dog is predisposed to joint problems.

Avoid Sudden Impacts: Take precautions to minimize risks of falls or impacts.

Genetic Screening: If you’re breeding dogs, consider genetic testing to identify predispositions to joint issues.

If your dog exhibits signs of joint dislocation, seek immediate veterinary attention. Early diagnosis and appropriate treatment are crucial for optimizing your dog’s recovery and long-term well-being.
