Vet’s 2025 Guide to Canine Spinal & Vertebral Malformations Diagnosis, Treatment & Home Monitoring🩺

By Dr. Duncan Houston BVSc

💡 What Are Vertebral Malformations?

Congenital vertebral malformations are abnormalities of the spine caused by improper development in utero. These include:

• 🟠 Hemivertebrae: half‑formed vertebrae leading to sharp curves—kyphosis, scoliosis, lordosis.
• 🟡 Butterfly vertebrae: sagittal cleft giving a butterfly appearance; usually incidental.
• 🟢 Transitional vertebrae: vertebrae with mixed features—often at cervicothoracic, thoracolumbar, or lumbosacral junctions.
• 🔵 Block vertebrae: fused vertebrae reducing flexibility and stressing adjacent discs.
• 🟣 Dens hypoplasia / atlantoaxial instability: underdeveloped C2 dens leading to cervical instability.

🚩 Who Is Affected?

• 🧬 Genetic predisposition: screw‑tailed breeds (French/English Bulldogs, Pugs, Boston Terriers), German Shepherds, Dobermans.
• 📏 Non‑brachycephalic breeds can also present atypical anomalies like block vertebrae.
• 🍼 Detected at birth or becomes apparent during growth spurts (4–10 months).

👀 Signs & Clinical Presentation

• 🦴 Visible spine distortions—curved back, hunched, or sway (lordosis, kyphosis, scoliosis).
• 🦵 Neurologic issues—hind limb weakness, paralysis, ataxia, crossing over limb placement.
• ⚠️ Incontinence when malformation impinges on nerves.
• 😖 Pain, reluctance to move, difficulty rising or climbing ｏｆｔｅｎ in severe compression.
• 🐾 Some unaffected—many mild anomalies only discovered on X‑ray.

🧪 Diagnosis & Imaging

1. Physical & neurological exam: assess gait, reflexes, pain.
2. Plain radiographs (x‑rays): key for identifying hemivertebrae, block, transitional vertebrae, dens hypoplasia.
3. CT scan: detailed bone evaluation for surgical planning.
4. MRI: essential for meningocele/spinal cord involvement and soft tissue compression.
5. Advanced tests: genetic screening not routine—investigation mainly via imaging and clinical signs.

🛠 Treatment Options

1. Conservative & Supportive Care 🏡

• 🧘♂️ Physical therapy: hydrotherapy, exercises, supports spinal strength and mobility.
• 🟰 Pain & anti‑inflammatory meds: NSAIDs, gabapentin, methocarbamol for pain and muscle spasms.
• 🦽 Mobility aids: harnesses, rugs, wheelchair for incontinent or weak dogs.
• 🏋️♀️ Weight management: essential to reduce spinal stress.

2. Surgical Intervention 🔧

• 🛠 Spinal decompression & stabilization: for severe compression from hemivertebrae/block vertebrae—improves neurologic signs.
• 🏥 Atlantoaxial stabilization: for dens hypoplasia—fixation of C1–C2 prevents spinal cord injury.
• 💉 Emerging techniques: stem‑cell therapy shows potential in select severe cases.

3. Prognosis & Long‑Term Outlook

• 🟢 Mild anomalies: Many dogs live symptom-free with conservative management.
• 🟡 Severe compression: early surgical decompression can stabilize and improve; prognosis varies.
• 🔴 Atlantoaxial instability: surgery significantly improves survival—without it, severe neurological deterioration is likely.
• ⚠️ Avoid breeding affected dogs due to hereditary causes.
