Spinal decompression surgeries
Decompression surgery (laminectomy) opens the bony canals through which the spinal cord and nerves pass, creating more space for them to move freely. Narrowing / stenosis of the spinal and nerve root canals can cause chronic pain, numbness, and muscle weakness in your arms or legs.
Laminectomy. A laminectomy removes areas of bone or tissue that are putting pressure on your spinal cord. The surgeon makes an incision (cut) over the affected section of spine down to the lamina (bony arch of your vertebra), to access the compressed nerve.
