A polyaxial screw is used for connecting vertebrae to rods in spinal surgery, particularly spinal fusion procedures. It is a type of screw whose spherical head is enclosed in a housing, which allows the screw a range of motion along several different axes relative to the housing. The ball joint allows the surgeon some flexibility in placing the ...
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 skeletal deformity caused by Scheuermann's disease can be corrected or partially corrected with surgical procedures, almost all of which include multi-level spinal fusion and hardware instrumentation, i.e., rods, pedicle screws, etc. While many patients are typically interested in getting surgery for their correction, it is important to ...
Bone morphogenetic protein (rhBMP) should not be routinely used in any type of anterior cervical spine fusion, such as with anterior cervical discectomy and fusion. [2] [3] There are reports of this therapy causing swelling of soft tissue which in turn can cause life-threatening complications due to difficulty swallowing and pressure on the respiratory tract.
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.
A clinician (i.e., a spine surgeon, orthopedic surgeon, sports medicine doctor, athletic trainer, medical massage therapist, physical therapist, physiatrist, osteopath or chiropractor) can develop a probable diagnosis of sacroiliac joint dysfunction by using a hands on approach through palpating the painful areas and performing the following ...
The three categories treated for types of spinal cord deficiencies are massive fusion of the cervical spine (Type I), the fusion of 1 or 2 vertebrae (Type II), and the presence of thoracic and lumbar spine anomalies in association with type I or type II Klippel–Feil syndrome (Type III). [citation needed]
It involves fusion of two or more levels utilizing screws, rods, and an interbody graft. It has a theoretical advantage over instrumented posterolateral fusion (iPLF) in that it provides better support for the vertebra along with several potential neurological benefits, but as of 2011 evidence demonstrating actual improved clinical outcomes was ...
