Instabilities of the cervical spine after complete or incomplete corpectomy may be the result from resection due to stenosis induced myelopathy, tumors, infections or fractures. In this article, we report a 49-year-old female patient after surgical decompression and stabilization at C5/7 with permanent cervicobrachialgia due to cervical stenosis at C5/7. Corpectomy of C6 and stabilization of C5/7 were performed with a combination of cage and plate. At an outpatient control 16 months after reoperation, the patient complained of neck pain, while the control X-ray showed a fracture of the implant...

BACKGROUND: Anomalies of vertebral arteries are rare, and usually detected incidentally. However, very rarely, they can manifest clinical symptoms. We describe such a symptomatic case of high cervical spinal cord compression associated with persistent C2 segmental arteries. CASE DESCRIPTION: A 67-year-old man presented with a 5-year history of worsening left-sided weakness and gait disturbance. Magnetic resonance imaging, 3D-computed tomography and digital subtraction angiography revealed anomalous courses of vertebral arteries, compressing the cervical spinal cord at C1 level from both sides...

Intraspinal synovial cyst is a rare cause of myelopathy. These cysts present most often in the lumbar and cervical parts of the spine but are more infrequent in the thoracic spine. We present a case of a 73-year-old man with an intraspinal, extradural synovial cyst at the Th2-3 level causing paraesthesia and weakness in the legs. A laminectomy and excision of the cyst were performed and the patient recovered fully. In the thoracic spine, synovial cysts are almost exclusively found in the lower part. Laminectomy, with excision, is the treatment of choice, although steroid injections have been described...

Chun-Chih Liao, Hsien-Wei Ting, Furen Xiao
An automatic atlas-free method for segmenting the cervical spinal cord on midsagittal T2-weighted magnetic resonance images (MRI) is presented. Pertinent anatomical knowledge is transformed into constraints employed at different stages of the algorithm. After picking up the midsagittal image, the spinal cord is detected using expectation maximization and dynamic programming (DP). Using DP, the anterior and posterior edges of the spinal canal and the vertebral column are detected. The vertebral bodies and the intervertebral disks are then segmented using region growing...
