About

Timothy F. Witham is a leading neurosurgical spine specialist whose research is driving the adoption of cutting-edge enabling technologies to enhance the precision and safety of complex spinal procedures. His work centers on the clinical translation of augmented reality (AR), robotic assistance, and advanced visualization tools for pedicle screw placement and spinal trauma management. Witham’s landmark 2019 meta-analysis, cited over 160 times, systematically evaluated 51,161 screws to establish the accuracy benchmarks for current pedicle screw techniques. He then pioneered the in-human application of AR assistance for S2 alar-iliac screw placement, demonstrating how retinal projection can improve the technical feasibility of challenging spinopelvic fixation. Further expanding the surgical toolkit, his team has investigated the utility of a robotic-arm-enabled 4K 3D exoscope as a versatile alternative to traditional microscopy in neurosurgical operations. Witham’s contributions are defining a new standard for image-guided spine surgery, directly translating novel hardware from proof-of-concept studies into practical, evidence-based solutions that improve patient outcomes.
