Degenerative L4-L5 spondylolisthesis and stenosis surgery: does over-level flavectomy technique influence clinical outcomes and rates of cranial adjacent segment disease?

Background: One of the most dreaded long-term complications related to L4-L5 lumbar arthrodesis is the onset of adjacent segment disease, which most frequently occurs at the cranial level. Few studies have compared the rates of cranial adjacent segment disease (CASD) in patients undergoing lumbar fusion associated with total laminectomy at the same level with those undergoing partial laminectomy. No study has examined the role of selective over-level flavectomy (OLF; i.

Degenerative Lumbar Stenosis Surgery: Predictive Factors of Clinical Outcome-Experience with 1001 Patients.

Background: Degenerative lumbar spinal stenosis (DLSS) carries a high risk of morbidity and represents a financial burden to society. A late diagnosis can lead to severe disability. Although lumbar decompressive surgery has been widely used worldwide, the proper preoperative factors to define the ideal candidates for decompression are missing.

Contralateral interlaminar approach for intraforaminal lumbar degenerative disease with special emphasis on L5-S1 level: A technical note.

Background: Intraforaminal disc herniations at the L5-S1 level are extremely surgically challenging lesions. Intracanal approaches frequently require partial or total facetectomy, which may lead to instability. Solely extraforaminal approaches may offer limited visualization of the more medial superiorly exiting and inferiorly exiting nerve roots; this approach is also more complicated at L5-S1 due to the often large L5 transverse process and the iliac wing.

Management of acute cerebellar infarction: one institution's experience.

Objective: The management of cerebellar infarctions is controversial. The aim of this study was to determine which patients require surgical treatment and which surgical procedure should be performed when a patient with a cerebellar infarction exhibits progressive neurological deterioration.

Methods: A total of 44 patients (24 male and 20 female patients; average age, 56 yr) were treated at our institution for cerebellar infarctions in the past 8 years.

Dorsal foramenal extraosseous epidural cavernous hemangioma.

Cavernous hemangiomas are vascular hamartomatous malformations that affect the central nervous system. This pathology is frequently encountered in the cerebral hemispheres, cerebellum, and brainstem. Cavernous hemangiomas infrequently occur at the spinal level or relative to an intramedullary localization; extramedullary epidural sites are also sometimes affected by this pathology.

Single cerebral metastasis from colorectal adenocarcinoma.

Single cases are described in 50% of reported intracranial metastases. Single cerebral metastasis from colorectal adenocarcinoma is not very common, with a frequency varying between 0.5% and 1%.
