Instability Surgery

instability-surgerySpondylolisthesis Surgery: This middle aged male had back and leg pain caused by instability in the lower back. This was identified with backward and forward bending x-rays showing movement (instability) with spondylolisthesis (forward shifting of the vertebrae) The treatment was surgical fusion of the unstable area, with bone graft between the vertebral bodies and also in the back, with spinal fixation internally. This reduces the deformity back to normal alignment. The x-rays show fusion (milky white bone) between the vertebrae as well as on either side.
