Posterior cervical decompression and fusion can be performed for various spinal conditions. Previous rates of pseudoarthrosis have been reported in up to 38% of patients. The use of bone morphogenic protein (BMP) has been approved for use in certain anterior lumbar interbody fusion techniques to decrease the incidence of pseudoarthrosis. Bone morphogenic protein in the anterior cervical spine c...

Fusion and rigid instrumentation have been currently the mainstay for the surgical treatment of degenerative diseases of the spine over the last 4 decades. In all over the world the common experience was formed about fusion surgery. Satisfactory results of lumbar spinal fusion appeared completely incompatible and unfavorable within years. Rigid spinal implants along with fusion cause increased ...

This study reports on a 70-year-old man with recurrent cervical myelopathy 20 years after anterior decompression and fusion of C4-7 using a free vascularised strut graft. The recurrent myelopathy was secondary to a kyphotic deformity of a fractured graft and residual ossification of the posterior longitudinal ligament with stenosis at C3/4. Intraoperative spinal cord-evoked potentials indicated...

Degenerative disc and facet joint disease of the lumbar spine is common in the ageing population, and is one of the most frequent causes of disability. Lumbar spondylosis may result in mechanical back pain, radicular and claudicant symptoms, reduced mobility and poor quality of life. Surgical interbody fusion of degenerative levels is an effective treatment option to stabilize the painful motio...

Five cases of syphilitic aortic aneurysm with erosion of the spinal column are reviewed. Four patients underwent operation. When erosion of the spine was mild or moderate, the aortic lesion only was treated. Aneurysm associated with extensive vertebral erosion was treated in two cases by anterior spinal fusion combined with replacement of the disc and part of the aorta. In one of these cases th...

Osteogenesis imperfecta (OI) is an inheritable bone disorder characterized by osseous fragility and ligamentous laxity. It is sometimes difficult to obtain bone union in patients with OI. The purpose of this report is to present a rare case of posttraumatic kyphosis due to a L1 burst fracture in a patient with OI, and to discuss how to treat it to achieve an adequate correction and circumferent...

Segmental spinal dysgenesis is a rare and challenging entity especially when associated with occult dysraphism. Experience with a female patient followed during a period of 10 years spanning from 5 to 15 years of age is reported. During that period the girl underwent three spinal operations consisting in one decompression and spinal cord untethering, one posterior instrumented fusion and a spin...

STUDY DESIGN Retrospective chart and radiographic review. PURPOSE To assess the incidence of and variables associated with spinal deformity progression after posterior segmental instrumentation and fusion at a single institution. Progression of the scoliotic deformity after posterior instrumented spinal fusion has been described. Recent studies have concluded that segmental pedicle screw cons...
