The standard management of these tumors is gross total resection. The outcome and extent of resection depends on location, size, patient's neurologic status, and experience of the surgeon. Heavily calcified spinal meningiomas often pose a challenge for achieving gross total resection without cord injury.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBJECTIVE<\/jats:title>\n                    <jats:p>To report our experience with the BoneScalpel Micro-shaver to resect heavily calcified areas of spinal meningiomas adherent to the spinal cord without significant cord manipulation, achieving gross total resection and outstanding clinical results.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>Seventy-nine and 82-yr-old females presented with progressive leg weakness, paresthesias, and gait instability. Magnetic resonance imaging of the thoracic spine showed a homogenous enhancing intradural extramedullary mass with mass effect on the spinal cord. Midline bilateral laminectomy was performed, and the dura was open in midline. The lateral portion of the tumor away from the spinal cord was resected with Cavitron Ultrasonic Surgical Aspirator while the BoneScalpel Micro-shaver (power level 5 and 30% irrigation) was brought into the field for the calcified portion of the tumor adherent to the spinal cord.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>Gross total resection was achieved for both cases.
