Surgical repair of a spinal fracture costs roughly $4,000 to $9,000, including imaging, surgery and intensive nursing afterwards.
If this has just happened, read the next section before anything else.
Getting them to the vet
Do not cradle an animal with a suspected spinal injury in your arms. A carried animal's spine flexes with every step, and an unstable fracture can shift against the spinal cord during the journey.
Instead:
- Slide them onto something rigid and flat — a board, a baking tray, a shelf from the oven, stiff cardboard
- Support head and body as one unit while you move them
- Secure them loosely so they cannot roll or struggle off
- Drive calmly. Speed helps far less than stillness.
Muzzle a dog in pain if you can do so safely — pain makes even gentle dogs bite — but never at the cost of extra handling.
Not the same as a slipped disc
This page is about a spine broken by trauma: hit by a car, a fall from a height, a dog fight, a kick, a cat that landed badly.
That is different from intervertebral disc disease, where a disc herniates and compresses the cord without the bone breaking. If your dog went down suddenly with no injury, see our guides to hemilaminectomy and ventral slot surgery instead.
What happens at the hospital
Stabilisation comes first. Many of these patients have other injuries — a bruised lung, internal bleeding, a fractured pelvis — and those are addressed before anyone thinks about the spine.
Neurological examination establishes where the injury is and how severe it is.
CT is now the standard imaging for spinal trauma: fast, and excellent at showing bone. MRI is added where the cord itself needs assessing.
Surgeons assess stability using a three-compartment model of the vertebral column. A fracture involving only one compartment may be stable enough for strict confinement and external support; one involving two or three usually needs surgical fixation.
"Deep pain sensation"
You will hear this phrase a great deal, and it deserves explaining.
It is the deepest and most resilient of the spinal cord's functions — the last one lost when the cord is severely injured. A neurologist pinches a toe firmly and watches not for a leg reflex but for a conscious response: turning the head, crying out, trying to bite.
Its presence after trauma is the strongest positive prognostic sign available. Its absence for more than 24 to 48 hours is the strongest negative one.
When you understand what is being tested, the conversation about your animal's chances becomes far less opaque.
The surgery
Implants — pins, screws and bone cement, or plates — hold the vertebrae rigid while the bone heals, sometimes combined with removing bone or disc material pressing on the cord.
It is difficult work in patients who are frequently multiply injured, and centre experience matters. Ask.
Recovery is measured in months
This is the part owners underestimate, and it deserves to be stated flatly before the decision is made.
- Several days to weeks in hospital
- Bladder management — many of these animals cannot urinate on their own initially and need manual expression or catheterisation, several times a day, at home
- Physiotherapy and rehabilitation, often for months
- Strict confinement for six to eight weeks
- Repeat imaging to confirm healing
Bladder care is what most owners find hardest and what they are least prepared for. Ask about it before you consent, not at discharge.
Prognosis, honestly
Many dogs and cats do walk again, particularly those with deep pain sensation intact. Some recover to a functional life with permanent deficits — a wobbly gait, some incontinence — and live perfectly happily that way. Some do not recover.
A frank prognosis before surgery is kinder than optimism, and any neurologist worth seeing will give you one.
Cats and pelvic injuries
Sacroiliac luxation — where the pelvis separates from the spine, common in cats hit by cars — is a more contained version of this problem. It often does well with a single screw, and sometimes with cage rest alone. If that is the diagnosis, the outlook is generally much better than this page's worst cases suggest.
Who isn't a candidate
- Other: Absent deep pain sensation below the injury for more than 24 to 48 hours, which carries a poor prognosis and makes the decision a genuinely open one rather than an automatic yes.
- Concurrent condition: An unstable polytrauma patient with chest or abdominal injuries — those are stabilised first, and spinal surgery waits until the patient can survive it.
- Other: A stable fracture with intact neurological function, where strict confinement and external support may be a reasonable alternative to implants.
Common questions
How much does spinal fracture surgery cost for a dog?
Roughly $4,000 to $9,000, covering emergency stabilisation, CT and often MRI, surgery with implants, and several days to weeks of intensive hospitalisation. Patients with other trauma injuries cost more, and the physiotherapy and nursing care that follow add to the total over the months of recovery.
Can a dog recover from a broken back?
Many do, particularly where deep pain sensation is still present at presentation. Recovery takes months and involves bladder management, physiotherapy and strict confinement. Some animals recover fully, some reach a functional life with permanent deficits and live happily, and some do not recover.
How do you transport a dog with a suspected spinal injury?
Slide them onto something rigid and flat — a board, baking tray or stiff cardboard — supporting head and body as one unit, and secure them so they cannot roll off. Do not carry them in your arms, because the spine flexes with each step and an unstable fracture can shift against the cord.
What does deep pain sensation mean in a paralysed dog?
It is the deepest spinal cord function and the last to be lost in severe injury. The neurologist pinches a toe firmly and looks for a conscious response — turning the head, crying out — rather than a reflex. Its presence is the strongest positive prognostic sign; its absence beyond 24 to 48 hours is the strongest negative one.
Do all spinal fractures need surgery?
No. Stability is assessed using a three-compartment model of the vertebral column. A fracture involving only one compartment, in an animal with intact neurological function, may be managed with strict confinement and external support. Fractures involving two or three compartments, or causing significant neurological deficits, usually need surgical fixation.
