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...

INTRODUCTION: Structural cages have been widely used in recent years to maintain motion segment height and stability in anterior lumbar interbody fusion (ALIF). High rate of clinical success and radiological fusion rate have been reported following single-level fusion using these cages. However, many biomechanical studies report insufficient stability, especially with extension loading. Posteri...

BACKGROUND The most common site of fractures in patients with ankylosing spondylitis (AS) is the cervical spine, especially the lower cervical spine and cervicothoracic junction. The optimal treatment for cervical spine fractures secondary to AS is controversial. This study aimed to explore the effects of posterior pedicle screw fixation alone on fractures of the lower cervical spine in patient...

STUDY DESIGN Prospective evaluation of gait and spinal range of motion (ROM) in adolescent idiopathic scoliosis (AIS) patients undergoing either an anterior or a posterior spinal fusion. OBJECTIVE Compare changes in gait and spine ROM between AIS patients undergoing either an anterior or posterior spinal fusion. SUMMARY AND BACKGROUND DATA Problems with AIS posterior spinal fusion and attem...

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...

Posterior spinal plating devices have recently made a re-emergence as both stand-alone devices and for use in conjunction with anterior fusion. Yet, the structural integrity of the posterior elements to support loads throughout the spine and the impact of plating on posterior element strength has not been well characterized. This study aims to quantify the mechanical strength of the posterior e...

Traumatic lumbar spondylolisthesis is a rare lesion and frequently noted in patients with multiple traumatic injuries. We report one case of L5 traumatic spondylolisthesis, which obtained successful decompression, reduction, interbody fusion and fixation by posterior lumbar interbody fusion, and got satisfactory outcome. We recommend early decompression, reduction, interbody fusion and fixation...

Posterior lumbar interbody fusion (PLIF) is a procedure used to treat problems such as disc degeneration, disc herniation, and spine instability. In this procedure, the surgeon works on the spine from the back and removes a spinal disc in the lower (lumbar) spine. The surgeon inserts bone graft material into the space between the two vertebrae where the disc was removed (the interbody space). T...

Osteoid osteoma is a small tumor of bone which affect spine in 10% of cases. The tumor has tendency to neural arc and the lumbar spine is most common site of presentation. Lesions of odontoid process are very rare. We present a 20-year-old man who had cervical pain for 8 month. The pain respond to medical therapy. After investigation there was a lytic lesion at the odontoid process with charact...
