Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. [1] This procedure can be performed at any level in the spine (cervical, thoracic, lumbar, or sacral) and prevents any movement between the fused vertebrae.
The spinal cord is the most complex yet organized part of the CNS. The entire spinal structure may be divided into 4 sections that create an overall S-shaped curve. These sections include the cervical, thoracic, lumbar, and sacral regions. Intervertebral discs stacked on top of one another make up the structure of the overall spine. These discs ...
A laminotomy is an orthopaedic neurosurgical procedure that removes part of the lamina of a vertebral arch in order to relieve pressure in the vertebral canal. [1] A laminotomy is less invasive than conventional vertebral column surgery techniques, such as laminectomy because it leaves more ligaments and muscles attached to the spinous process intact and it requires removing less bone from the ...
With spinal fusion, the recovery time may be longer. In some cases after laminectomy and spinal fusion, it may take several months to return to normal activities. [1] Potential complications include bleeding, infection, blood clots, nerve injury, and spinal fluid leak. [1]
In the spine, there is bone formation along the anterior longitudinal ligament and sometimes the posterior longitudinal ligament, which may lead to partial or complete fusion of adjacent vertebrae. The facet and sacroiliac joints tend to be uninvolved. The thoracic spine is the most common level involved. [2]
Lumbosacral transitional vertebrae consist of the process of the last lumbar vertebra fusing with the first sacral segment. [1] While only around 10 percent of adults have a spinal abnormality due to genetics, a sixth lumbar vertebra is one of the more common abnormalities. [2] Sacralization of the L5 vertebra is seen at the lower right of the ...
Every year, approximately 130,000 lumbar spinal fusion procedures that end at the pelvis are performed in the United States to treat adult deformity and degenerative spine conditions. About SI-BONE, Inc. SI-BONE (NASDAQ: SIBN) is a global leader in technology for surgical treatment of sacropelvic disorders. Since pioneering minimally invasive ...
Bertolotti's syndrome is characterized by sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. It involves a total or partial unilateral or bilateral fusion of the transverse process of the lowest lumbar vertebra to the sacrum, leading to the formation of a transitional 5th lumbar vertebra.
