A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).
Signs and symptoms include low back pain, pain that radiates down the leg, numbness around the anus, and loss of bowel or bladder control. [1] Onset may be rapid or gradual. [1] The cause is usually a disc herniation in the lower region of the back. [1] Other causes include spinal stenosis, cancer, trauma, epidural abscess, and epidural hematoma.
A compression fracture is a collapse of a vertebra. It may be due to trauma or due to a weakening of the vertebra (compare with burst fracture ). This weakening is seen in patients with osteoporosis or osteogenesis imperfecta , lytic lesions from metastatic or primary tumors , [ 1 ] or infection. [ 2 ]
Causes can be bone fragments from a vertebral fracture, a tumor, abscess, ruptured intervertebral disc or other lesion. When acute it can cause a medical emergency independent of its cause, and require swift diagnosis and treatment to prevent long-term disability due to irreversible spinal cord injury .
Human anatomy of the back. Back injuries result from damage, wear, or trauma to the bones, muscles, or other tissues of the back. Common back injuries include sprains and strains, herniated discs, and fractured vertebrae. [1] The lumbar spine is often the site of back pain.
Acute compartment syndrome (ACS) is a medical emergency that can develop after traumatic injuries, such as in automobile accidents or dynamic sporting activities – for example, a severe crush injury or an open or closed fracture of an extremity. Rarely, ACS can develop after a relatively minor injury, or due to another medical issue. [28]
The symptoms of a vertebral collapse ("compression fracture") are sudden back pain, often with radicular pain (shooting pain due to nerve root compression) and rarely with spinal cord compression or cauda equina syndrome. Multiple vertebral fractures lead to a stooped posture, loss of height, and chronic pain with resultant reduction in ...
Chance fracture – compression injury to the anterior portion of a vertebral body with concomitant distraction injury to posterior elements; Holdsworth fracture – an unstable fracture dislocation of the thoraco lumbar junction of the spine; Distraction is where there is a pulling apart of the vertebrae. [2] Distraction injuries generally ...
