BACKGROUND Several studies suggest fusion rates are higher with anterior cervical discectomy and fusion procedures if supplemented with a plate. However, plates may be associated with higher postoperative morbidity and higher rates of dysphagia. This led to the development of a cervical stand-alone cage with integrated fixation for zero-profile segmental(More)
Study Design Narrative review. Objective To elucidate the current concepts in diagnosis and treatment of traumatic spondylolisthesis of the axis. Methods Literature review using PubMed, Google Scholar, and Cochrane databases. Results The traumatic spondylolisthesis of the axis accounts to 5% of all cervical spine injuries and is defined by a bilateral(More)
Osteoblastoma is a rare, benign bone tumor that accounts for approximately 1 % of all primary bone tumors and 5 % of spinal tumors, mostly arising within the posterior elements of the spine within the second and third decades of life. Nonspecific initial symptoms mainly neck or back pain and stiffness of the spine remain often undiagnosed and the(More)
Unstable fractures of the thoracolumbar spine without neurological deficit can be treated by percutaneous screw-rod stabilization techniques. Percutaneous techniques are preferable especially in elderly patients with a high rate of comorbidities due to decreased blood loss and shorter operation times. Minimized soft tissue trauma may further allow earlier(More)
Introduction Osteoblastoma is a rare primary neoplasm of bone, categorized as a benign bone tumor. It differs from osteoid osteoma in its ability to grow larger than 2.0 cm in diameter. Osteoblastoma is a bone-forming lesion about 20 times less common than osteosarcoma. According to the Musculoskeletal Society Tumor Staging (MSTS) system of benign bone(More)
Incomplete cranial burst fractures are often associated with destruction of the neighbouring intervertebral disc. In these cases additional anterior vertebral column reconstruction might be beneficial to avoid posterior implant failure and secondary loss of correction with kyphotic deformity. Thoracotomy is the standard approach to reconstruct the anterior(More)
Injuries of the occipital condyles are rare. While the majority of occipital condyle fractures can be treated conservatively, surgery is recommended in craniocervical misalignment and instability. Open reduction and temporary occipito-cervical stabilization might be an alternative to fusion or halo treatment. This Grand Round case presentation describes(More)
Introduction Neurinomas represent the most frequent tumor lesions of the spine with prevalence of the lower cervical spine and the lumbar spine. As much as 29% of all primary spinal tumors are intraspinal neurinomas [1]. Neurinomas can occur in every age. The peak seems to be between the 4th and 6th decade of life. There is no significant prevalence between(More)
Cervical neuroforaminal stenosis is a common cause of neck pain and radicular arm pain. At the entrance of the foraminal canal the nerve root can be encroached by a cartilaginous cap, a bony spondylophyte, a synovial cyst or a combination of them. Additionally bony spurs arising from the uncovertebral (Luschka) joints might compress the anterior aspect of(More)
First we performed a closed reduction and ACDF C6–7. After a week, additional posterior stabilization and monosegmental fusion was indicated to provide optimal stability and a good restoration of cervical spine lordosis. Patient is placed in a prone position fixing the head with a Mayfield clamp. Lateral X-ray is helpful for confirming good alignment of the(More)
