Hind limb weakness or sudden paralysis in rabbits is often caused by spinal cord injury from a fractured or luxated lumbar vertebra — an injury that happens in an instant when a rabbit kicks forcefully against restraint. Prompt, careful handling is critical; the prognosis varies widely based on injury severity.

Why Rabbits Are Prone to Spinal Injury
Rabbits have powerful hindquarters built for explosive acceleration, but their spinal column is relatively fragile compared to the muscular force they can generate. When a rabbit panics and kicks violently — especially while being restrained with the hindquarters unsupported — the force can fracture or dislocate the lumbar vertebrae, causing acute spinal cord compression or transection.
The L6–L7 and L7–S1 vertebral junctions are the most common injury sites. The spinal cord in rabbits ends at approximately L7 (the conus medullaris), making injuries in this region likely to affect hind limb motor and sensory function. As described in Quesenberry & Carpenter's Ferrets, Rabbits and Rodents: Clinical Medicine and Surgery, spinal fractures are among the most common serious injuries seen in domestic rabbits and are most often caused by improper handling.
Other causes of hind limb weakness include spinal cord compression from E. cuniculi (a parasitic infection — see rabbit-e-cuniculi-signs), spondylosis (bony bridging of vertebrae in older rabbits), intervertebral disc disease, and neoplasia.
Signs of Spinal Injury in Rabbits
- Sudden complete or partial hind limb paralysis — the rabbit cannot use its back legs at all, or uses them weakly and asymmetrically
- Dragging of the hind legs while moving with front legs only (paresis → paralysis)
- Loss of bladder and/or bowel control — urine scald (wet fur around the perineum) or inability to defecate normally
- Posture change — hindquarters lower than normal, spine appears curved
- Vocalizing or flinching when the spine or hindquarters are touched (if pain sensation remains)
- Absent tail movement in severe injuries
In complete cord transection, the rabbit loses motor function AND pain sensation below the injury — touching the hind paws produces no response. In partial injuries, some voluntary movement or at least deep pain perception (withdrawal reflex) remains. The presence or absence of deep pain sensation is the single most important prognostic indicator.
Diagnosis
- Spinal radiographs — identify fractures, dislocations, or spondylosis. The entire spine should be radiographed.
- CT or MRI — gold standard for spinal cord compression assessment; identifies soft tissue and disc pathology not visible on radiographs. Cost: $400–900.
- Neurological examination — assesses motor function, proprioception (awareness of limb position), superficial and deep pain sensation in the hind limbs
- Urinalysis — baseline assessment for bladder dysfunction
Treatment and Prognosis
Immediate: Cage rest and strict restriction of movement — a rabbit with a spinal fracture can worsen significantly with any jumping or struggling. Sedation or analgesia (meloxicam, buprenorphine) is given immediately to reduce pain and involuntary movement.
Surgical stabilization: Possible for some fracture-luxations, but rabbit spinal surgery is technically demanding and performed only at referral centers. Most cases with a displaced fracture and complete cord transection are managed medically.
Medical management of partial injuries: corticosteroids (controversial), NSAIDs, vitamin E, and supportive care. Bladder expression (manually emptying the bladder 2–4× daily) is required if voluntary urination is lost. Urinary catheterization carries infection risk in rabbits and is usually avoided in favor of manual expression.
Nursing care: Padded substrate, prevention of urine scald with frequent cleaning, passive range-of-motion exercises, and monitoring for GI stasis (pain and stress predispose to this). Perineal skin care is essential — urine scalding rapidly leads to severe moist dermatitis.
Prognosis: Rabbits with preserved deep pain sensation and partial motor function have a reasonable prognosis for recovery with intensive nursing care — 4–8 weeks of cage rest and physiotherapy. Rabbits with complete cord transection (absent deep pain) have a poor prognosis for hind limb function recovery, though some can live comfortably as "paraplegic" pets with excellent nursing care and the use of a wheeled cart (rabbit wheelchair).
Cost for diagnosis and initial treatment: $300–800; surgical referral cases: $2,000–5,000+; long-term nursing and recheck costs add $50–200/month.
When to See a Vet
Call your vet today if:
- Your rabbit is dragging its hind legs or moving them asymmetrically
- Your rabbit appears to have lost bladder or bowel control
- Your rabbit cried out suddenly after being handled or dropped and is now abnormal
Go to the ER immediately if:
- Your rabbit has sudden complete hind limb paralysis
- Your rabbit is in obvious pain, vocalizing, or in a distressed posture
- The injury just occurred — rapid imaging and stabilization can preserve function

Frequently Asked Questions
Can a rabbit recover from hind limb paralysis? It depends on whether the spinal cord is partially or completely damaged. Rabbits with preserved deep pain sensation in the hind limbs often recover partial or full function over weeks with cage rest and supportive care. Those with complete cord transection rarely regain voluntary hind limb movement but can live well-managed lives with nursing support and a rabbit wheelchair.
How do I correctly pick up a rabbit to prevent spinal injury? Always support the rabbit's hindquarters fully when lifting — never allow the hind end to dangle unsupported. Approach calmly, scoop under the body with both hands, and hold the rabbit securely against your body. Do not restrain a struggling rabbit on its back, and place the rabbit down gently — do not drop or release suddenly.
How much does spinal injury treatment cost in a rabbit? Initial exam, radiographs, and pain management typically cost $300–600. Advanced imaging (CT/MRI) adds $400–900. Surgical stabilization at a referral center costs $2,000–5,000 or more. Long-term nursing care for a paraplegic rabbit adds $50–200/month in veterinary rechecks and supplies.
Is it humane to keep a paraplegic rabbit? Many paraplegic rabbits live happy, comfortable lives with attentive owners. Requirements include: twice-daily manual bladder expression, meticulous skin care to prevent urine scald, padded flooring, a wheeled mobility cart, and frequent health monitoring. The rabbit's quality of life — whether it eats well, grooms, remains alert and social — guides the decision.
Can E. cuniculi cause similar signs to spinal injury? Yes — E. cuniculi (a microsporidian parasite) causes progressive hind limb paresis and head tilt in rabbits and can look identical to traumatic spinal injury without imaging. Serology for E. cuniculi and a treatment trial with fenbendazole help distinguish this from structural spinal disease.
