Final answer:
Laminectomy is a surgical procedure that involves removing a portion of the vertebral bone to relieve pressure on the spinal cord or nerves. It does not involve the excision of the bursa.
Step-by-step explanation:
Laminectomy is a surgical procedure that involves the removal of a portion of the vertebral bone called the lamina. It is performed to relieve pressure on the spinal cord or nerves caused by conditions such as herniated discs, spinal stenosis, or tumors. The excision of the bursa, on the other hand, refers to a surgical removal of a fluid-filled sac that reduces friction between tendons and bones near joints. These procedures are not related, and a laminectomy should not involve the excision of the bursa.
