Paraplegia:
- It refers to partial or complete loss of motor function in hind limbs of animals.
- Paraplegia often involves loss of sensation; of pain, temperature, vibration, and position.
- It is a distinct clinical feature in spinal cord affection.
Types of paraplegia:
Paraplegia in extension:
- It results only when the pyramidal tract is involved leaving extrapyramidal tract intact.
- Posterior limbs are always kept in attitude of extension owing to hypertonicity of extensor group of muscles, so known as paraplegia in extension.
Paraplegia in flexion:
- It results when lesion involve both the pyramidal and extrapyramidal tracts in spinal cord.
- This is seen in case of compression of spinal cord.
- It is so named because posterior limbs are kept in latitude of flexion owing to increased tone of flexor group of muscles.
Etiology:
- Acute spinal cord injuries; spinal fracture or luxation
- Automobile accidents, gunshot wounds, bite wounds are common causes of spinal cord injuries in dogs and cats
- Fall are common causes in horse.
- Cattle are susceptible to injuries during breeding
- Pathological fracture common in cattle, sheep, goat, pig due to malnutrition or vertebral osteomyelitis.
- Concussion of spinal cord
- Spondylopathy
- Abscess in spinal cord
- Intervertebral disc protrusion
- Tubercular lesion in vertebrae
- Infections like discospondylitis
- Spinal tumors cause compression of spinal cord
- Myelitis and meningitis
- Vascular problems: Blood clots or other vascular tissues can lead to inadequate blood supply to spinal cord.
Clinical Findings:
- Loss of voluntary hind limb movement
- Loss of sensation in hind limb
- Inability to bear weight on hind limbs
- Abnormal gait or posture; limping, rigid or stiff hind limbs
- Pain, if underlying cause is painful.
Diagnosis:
- Physical examination to assess reflexes and sensation
- Radiographs (X-rays) to evaluate spine fractures, disc herniation, tumors
- Advanced imaging techniques like MRI or CT scans for a more detailed view of the spinal cord
- Blood tests to check for infections or other systemic issues.
Treatment:
- In cases of spinal cord compression due to disc disease or tumors, surgery may be necessary to relieve pressure and restore function.
- For conditions like infections or inflammatory diseases, medications such as antibiotics or anti-inflammatories may be prescribed
- Antibiotics are prescribed based on results of AST. Penicillin, cephalosporin group of drugs are commonly used to encounter infections.
- Anti-inflammatories; Meloxicam @0.2-0.5 mg/kg, IV/IM/SC based on severity of pain and inflammation.
- Rehabilitation and physical therapy can help animals regain strength and mobility after paraplegia.
- Pain management and supportive care can improve the quality of life for animals with chronic conditions.
- Some animals may benefit from mobility aids like wheelchairs.
