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.
Studies by Ha, et al., show that the incidence of SI joint degeneration in post-lumbar fusion surgery is 75% at 5 years post-surgery, based on imaging. [35] Studies by DePalma and Liliang, et al., demonstrate that 40–61% of post-lumbar fusion patients were symptomatic for SI joint dysfunction based on diagnostic blocks. [36] [37]
The most common lumbar spinal fusion occurs between L4 and L5. [4] A lumbar spinal fusion may be recommended when non-surgical treatment options for severe degenerative disc disease are ineffective. A laminotomy would not be effective in this case, since this procedure is concerning a degenerated disc that needs to be removed in order to ...
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.
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.
Premia Spine developed the TOPS System and initiated a US trial to compare it with the traditional transforaminal lumbar interbody fusion (TLIF) procedure. Under the Investigational Device Exemption (IDE) study by the FDA, the system was available to a limited number of U.S. patients at select hospitals and institutions.
