Transpedicular screw-rod fixation of the lumbar spine: operative technique and outcome in 104 cases.
A total of 104 patients underwent transpedicular spinal instrumentation using the Cotrel-Dubousset (71 cases) or the Texas Scottish Rite Hospital (33) screw-rod system. Surgery was performed for lumbar vertebral column instability secondary to fractures (28 cases), spondylolisthesis (29), tumors (four), vertebral osteomyelitis (two), or postoperative causes (41). Pseudoarthrodesis due to failure of a prior fusion was present in 37 cases. ⋯ Pedicle screw-rod fixation offers biomechanical advantages compared to other forms of internal fixation for the lumbar spine. It enables short-segment fixation with preservation of lumbar lordosis and adjacent normal motion segments. This technique provides a highly successful method to obtain arthrodesis, even with prior pseudoarthrosis.

The AANS: the national and international organization for neurological surgery.
The President of the American Association of Neurological Surgeons (AANS) validates the AANS as the national neurosurgical organization. He describes improved management of major committees of neurological surgery by the Joint Officers of the AANS and the Congress of Neurological Surgeons. A strong argument and proclamation are presented to expand the international role of the former Harvey Cushing Society.
