Dailey, Andrew T. | Agreement between orthopedic surgeons and neurosurgeons regarding a new algorithm for the treatment of thoracolumbar injuries: a multicenter reliability study | Introduction: Considerable variability exists in the management of thoracolumbar (TL) spine injuries. Although there are many influences, one significant factor may be the treating surgeon's specialty and training (ie, orthopedic surgery vs. neurosurgery). Our objective was to assess the agreement ... | Thoracolumbar injuries; Rating; Classification; TLISS; Neurosurgery; Interspeciality reliability | 2006 |

Kestle, John R. W. | Management of shunt infections: a multicenter pilot study | Object. Approximately 10% of cerebrospinal fluid (CSF) shunt operations are associated with infection and require removal or externalization of the shunt, in-hospital treatment with antibiotic agents, and insertion of a new shunt. In a previous survey, the authors identified substantial variation i... | Shunt infections; Ventriculoperitoneal shunt; Treatment evaluation | 2006 |
