Kay suffered from debilitating muscle cramps and lower back pain due to spondylolisthesis, a common condition of the lumbar spine. When non-surgical treatment options failed, she turned to spinal neurosurgeon Timothy Witham for help. He used new augmented reality technology to precisely place spinal instruments in his back. Seven months after surgery, Kay has returned to daily activities pain-free and is enjoying life. #ARSurgery #JohnsHopkins
