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 Charité, a mobile core device for use in the lumbar spine, was approved first, in 2004, but is no longer in use. prodisc, the longest continually used disc replacement device in the US, is a fixed core device manufactured by Centinel Spine and was approved in 2006 for the lumbar spine with a cervical device approved in 2007.
Degenerative spondylolisthesis at L5-S1. (A) CT sagittal view of a low grade slip. (B) Lateral radiograph pre-operative intervention. (C) Surgically treated with L5–S1 decompression, instrumented fusion and placement of an interbody graft between L5 and S1. Both minimally invasive and open surgical techniques are used to treat anterolisthesis ...
X-ray of interbody fusion cage in cervical vertebrae, Juliet system. X-ray of interbody fusion cage in L5S1 vertebrae. An interbody fusion cage (colloquially known as a "spine cage") is a prosthesis used in spinal fusion procedures to maintain foraminal height and decompression. They are cylindrical or square-shaped devices, and usually threaded.
They found 68% of lumbar fusion patients still unable to return to work two years after surgery. This was in stark contrast to reports of 68% post-op satisfaction in many series. [ 199 ] [ 142 ] In a follow-up study it was found that the use of intervertebral fusion devices rose rapidly after their introduction in 1996.
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.
Instrumented posterior lumbar interbody fusion (iPLIF) is a common spinal fusion surgical technique for addressing low back pain resulting from degenerative lumbar spine disorders. [1] It involves fusion of two or more levels utilizing screws, rods, and an interbody graft.
The majority of disc herniations occur in the lumbar spine (95% at L4–L5 or L5–S1). [21] The second most common site is the cervical region (C5–C6, C6–C7). The thoracic region accounts for only 1–2% of cases.
