We present a case of a 55-year-old male with progressive neurological deficits that appeared dramatically. MRI detected a spinal epidural hematoma at the cervicothoracic junction and blood tests showed leukocytosis, mild anemia, and thrombocytosis. Spontaneous spinal epidural hematoma (SSEH) as the initial presentation of leukemia was diagnosed. Urgent posterior decompression was performed after 28 h from acute onset of backache, and the patient experienced remarkable improvement in neurological findings.
We present a 15-year-old boy with severe cervical kyphosis due to neurofibromatosis (NF), who underwent one-stage anterior fusion and posterior correction using pedicle screw fixation. The kyphosis was corrected from 72 degrees to 35 degrees. At the follow-up 16 months postoperatively, anterior fusion and posterior stabilization had been obtained without correction loss. Cervical pedicle screw fixation is a useful method for the correction of severe cervical kyphosis in patients with NF.
This article attempts to evaluate the effectiveness of the ultra-high-molecular-weight polyethylene (UHMW-PE) cable system in atlantoaxial transarticular screw fixation and posterior fusion through the clinical results of 10 postoperative patients with atlantoaxial subluxation secondary to rheumatoid arthritis. Among them, one patient with only one screw placed owing to an anomalous vertebral artery had the correction loss of the 3-mm atlas-dens interval after surgery. Another patient had a second operation to remove the screw and cable after 2 years 11 months because a unilateral transarticular screw had come to protrude through the lateral mass of the atlas ventrally. All patients had achieved C1-C2 osseous fusion without any complications associated with this cable system. The UHMW-PE cable is a very useful material as sublaminar wiring in atlantoaxial transarticular screw fixation and posterior fusion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
