In order to locate the site of spinal cord compression we perform a specialist x-ray technique called myelography which is carried out under general anaesthesia– this involves carefully injecting a clear sterile solution into the space along side the spinal cord. This solution runs by gravity along the spinal cord and stops or deviates at the site of the problem, allowing us to know where exactly to surgically relieve the compression on the spinal cord.
