Newswise — Charlottesville, VA (August 1, 2020). A joint effort of the Journal of Neurosurgery Publishing Group and the Lumbar Spine Research Society, the August issue of Neurosurgical Focus (Vol. 49, No. 2 []) looks at lumbar spinal osteoporosis.

 Articles in this issue address the challenges encountered when elective lumbar spine surgery is performed in patients with osteoporosis. Identification of poor bone quality using quantitative computed tomography and magnetic resonance imaging as well as dual-energy x-ray absorptiometry, preoperative medical treatments to optimize bone quality, timing of surgery, and adjustments to surgical procedures to manage osteoporosis are discussed.

  • “Preoperative bone health assessment and optimization in spine surgery” by Paul A. Anderson et al.
  • “Editorial: Is preoperative bone health assessment and optimization in spine surgery a good idea?” by Timothy F. Witham et al.
  • “Osteoporosis in spine surgery patients: what is the best way to diagnose osteoporosis in this population?” by Jeffery D. St. Jeor et al.

Founded in 1931 as the Harvey Cushing Society, the American Association of Neurological Surgeons (AANS) is a scientific and educational association with more than 10,000 members worldwide. The AANS is dedicated to advancing the specialty of neurological surgery in order to provide the highest quality of neurosurgical care to the public. All active members of the AANS are certified by the American Board of Neurological Surgery, the Royal College of Physicians and Surgeons (Neurosurgery) of Canada, or the Mexican Council of Neurological Surgery, AC. Neurological surgery is the medical specialty concerned with the prevention, diagnosis, treatment, and rehabilitation of disorders that affect the entire nervous system including the brain, spinal column, spinal cord, and peripheral nerves.
