Predictors of peritumoral edema after stereotactic radiosurgery of supratentorial meningiomas.
Anecdotal evidence suggests that radiosurgical ablation of parasagittal meningiomas may be associated with increased risk of subsequent edema. Potential predictors of postradiosurgical peritumoral edema, including parasagittal tumor location, tumor size, and treatment dose, were evaluated. ⋯ Patients with parasagittal meningiomas are at greater risk of developing peritumoral symptomatic edema after SRS. Close follow-up after SRS may be particularly important in such patients. These results highlight the need to pursue strategies that could decrease the incidence of postradiosurgical edema in patients with parasagittal meningioma.

Significant advances have been made in the contemporary management of thoracolumbar spinal deformities, including improved segmental bony fixation, techniques for osteotomy, and mechanically powerful reduction maneuvers, which now allow the spinal surgeon to correct severe, complex, and rigid spinal deformities. However, one of the major limitations of surgical intervention has been the high complication rates associated with these surgical endeavors. ⋯ The open exposures for long-segment fixation result in additional blood loss, increased rates of infection, and prolonged immobilization caused by postoperative pain. Minimally invasive techniques attempt to overcome these drawbacks of the open exposures, and this report reviews preliminary experience in treating spinal deformities with long-segment minimally invasive internal fixation.

Historical Article
The Harvard Neurosurgical Service at the Children's Hospital Boston and Brigham & Women's Hospital, 1912-2007.
The Harvard Neurosurgical Service at Brigham and Women's Hospital and Children's Hospital Boston has a distinguished history, beginning in 1912 when Dr. Harvey Cushing became surgeon-in-chief at the Peter Bent Brigham Hospital. After Cushing left in 1932, the Children's Hospital had a dominant role, with the creation and development of pediatric neurosurgery under Franc D. ⋯ Despite reporting on more than 2500 cases a year, the combined service continued to have a strong academic program. This was helped by a residency with two required research years, an academic day each week, faculty committed to research, strong scientific collaborations, and contributions from many visiting neurosurgeons and research fellows. In its first 94 years, the service has been a strong force in clinical, educational, political, and research efforts in neurosurgery.

Case Reports Comparative Study
Contralateral C7 transfer via the prespinal and retropharyngeal route to repair brachial plexus root avulsion: a preliminary report.
We sought to investigate a shorter and safer route for contralateral C7 transfer. ⋯ Transection of the bilateral scalenus muscles can reduce the length of the nerve graft and allow the C7 nerve to be transferred more smoothly and safely through the prespinal and retropharyngeal route; this method also favors nerve regeneration and functional recovery.

To review current classification systems for adolescent and adult scoliosis. ⋯ The importance of scoliosis classification schemes lies in their ability to standardize communication among health care providers. With regard to the classification of adolescent scoliosis, the Lenke system has addressed many of the significant limitations of the King system and is now the standard classification scheme. Classification schemes for adult scoliosis have been reported only recently, and each offers specific advantages (the simple pathogenesis-based system of Aebi, the strong clinical relevance of the Schwab system, and the richly descriptive Scoliosis Research Society system). This article highlights the salient features of currently used scoliosis classification systems.
