237 Schmidt, Meic H.Thoracoscopic vertebral body replacement with an expandable cage after ventral spinal canal decompressionOBJECTIVE: Minimally invasive thoracic anterior surgery using a thoracoscopic approach has evolved to include spinal biopsy, debridement, discectomy, decompressive corpectomy, interbody fusions, and internal fixations. Minimal access techniques can potentially decrease surgical access morbidity and...2007-01-01
238 Couldwell, William T.Initial experience related to the use of the Cosman-Roberts-Wells stereotactic instrumentInitial experience with a new arc-radius design of stereotactic frame that interfaced with the existing components of the Brown-Roberts-Wells instrument is reported. Over a 6-month period, 32 procedures were performed on 23 males and nine female patients (mean age 32 years); these included 27 ster...Image-directed stereotaxis; Stereotactic instrument; Cosman-Roberts-Wells stereotaxy1990
239 Kestle, John R. W.; Townsend, Jeannette J.; Brockmeyer, Douglas LeeJuvenile pilocytic astrocytoma of the brainstem in childrenObject. In reports involving the operative treatment of brainstem tumors, multiple histological types are often grouped together. To determine prognosis after resection, histology-specific data may be helpful. Methods.
