What is Spinal Decompression Surgery? A Consultant Orthopaedic Spine Surgeon's Guide
Spinal decompression surgery is a procedure to relieve pressure on the spinal cord or nerve roots. It involves removing the bone, ligament, or disc tissue causing compression. This surgery is commonly performed for spinal stenosis. Dr. Purnajyoti Banerjee, a Consultant Orthopaedic Spine Surgeon in London, employs minimally invasive techniques wherever suitable. These methods preserve healthy supporting structures while fully relieving affected nerves. Learn more about spinal stenosis on the NHS website.
