I attended a talk last night by Spinal Surgeon Manoj Krishna. This involved listening to when surgery is indicated and case studies where patients had been having pain for over 15 years and were pain free after PLIF surgery (Posterior Lumbar Interbody Fusion). This involves removing the disc and bolting the two vertebra together. The highlight of the evening was having a go ourselves on a demonstration spine – someone managed to get the angle wrong and go through the spinal canal – ouch!
