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 a new augmented reality technology to precisely place spinal instruments in her back. Seven months after surgery, Kay has resumed her daily activities without pain and is enjoying life. #ARsurgery #JohnsHopkins
