OrthoSouth, the region’s leading orthopedic practice, is thrilled to announce the addition of two distinguished spine neurosurgeons, Dr. Raul J. Cardenas and Dr. Jason Andrew Weaver, to its multidisciplinary spine team.

Dr. Cardenas has led a rich and productive career, including roles at the University of Tennessee Health Science Center and Semmes-Murphey Clinic. His innovative approach to minimally invasive spine surgery has helped patients across the Mid-South find relief from painful conditions. He is a third-generation neurosurgeon; his grandfather trained in Havana, Cuba, in the 1930s and eventually became Mexico’s first fully trained neurosurgeon, while his father trained at Semmes-Murphey Clinic in the 1970s. He has performed charitable operations with his father in Mexico to care for the underserved. Dr. Cardenas is a leader in the field and a dedicated educator, shaping future surgeons through his roles at multiple prestigious medical institutions, including the University of Texas Health Science Center in Houston and Louisiana State University Health Science Center. He is fluent in both English and Spanish.

Dr. Weaver is a board-certified neurosurgeon. He brings 20 years of experience in minimally invasive spine surgery and complex spine surgery to OrthoSouth. He is also fellowship-trained in spine tumor surgery at MD Anderson Cancer Center, focusing on complex reconstructive surgery of the spine. He focuses on outpatient surgery and utilizing the latest advancements to his patients’ benefit. Dr. Weaver has served the Memphis community notably through his previous affiliations with the Semmes-Murphey Clinic and the University of Tennessee. He has also held the position of Team Neurosurgeon for a number of Memphis-based professional and collegiate sports teams. His contributions to neurosurgical advancements and his commitment to clinical excellence have made him a pillar in the neurosurgical community. His goal is to provide a conservative, comprehensive management approach to his patients with a wide variety of neck and back issues.
