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 ]
Spinal cord compression is a form of myelopathy in which the spinal cord is compressed. Causes can be bone fragments from a vertebral fracture, a tumor , abscess , ruptured intervertebral disc or other lesion.
Traumatic SCI can result in contusion, compression, or stretch injury. [5] It is a major risk of many types of vertebral fracture. [70] Pre-existing asymptomatic congenital anomalies can cause major neurological deficits, such as hemiparesis, to result from otherwise minor trauma. [71]
Burst fracture – in which a vertebra breaks from a high-energy axial load; Compression fracture – a collapse of a vertebra, often resulting in the form of a wedge-shape due to larger compression anteriorly; Chance fracture – compression injury to the anterior portion of a vertebral body with concomitant distraction injury to posterior ...
The burst fracture is categorized by the "severity of the deformity, the severity of (spinal) canal compromise, the degree of loss of vertebral body height, and the degree of neurologic deficit." [2] Burst fractures are considered more severe than compression fractures because long-term neurological damage can follow. The neurologic deficits ...
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 ...
Because myelomalacia involves a damaged spinal cord, it may occur in any individual. Those most at risk are the geriatric population due to weaker bone density. Once the spinal injury has occurred, one of two things may happen. Firstly, hemorrhaging within the spinal cord may cause compression, which damages the spinal cord even further.
A flexion teardrop fracture is a fracture of the anteroinferior aspect of a cervical vertebral body due to flexion of the spine along with vertical axial compression. [1] The fracture continues sagittally through the vertebral body, and is associated with deformity of the body and subluxation or dislocation of the facet joints at the injured level. [2]
