L4-5 Hemilaminectomy, Discectomy and Fusion Procedure - Medical Illustration, Human Anatomy Drawing
This stock medical exhibit depicts an L4-5 hemilaminectomy, discectomy and fusion procedure. The first two illustrations portray a right L4-5 hemilaminectomy and discectomy surgery. The first illustration shows a posterior view of the lower back and lumbar spine of a caucasian figure. In it, an incision is made into the lower back from L4-S1 to expose the L4-5 disc space. The second illlustration shows a right sided hemilaminectomy in which the L4 lamina is removed. Also, the herniated L4-5 disc herniation is removed. The third illustration begins the L4-5 decompression laminectomy, discectomy and fusion surgery. It shows a posterior view of the lower back and lumbar spine of a caucasian figure. In it, a new, larger incision is made from L3-S1 to re-expose the L4-5 disc space. Also in this illustration, the harvest site of a right hip bone graft is indicated. The fourth illustration shows the decompression laminectomy and discectomy performed at L4-5. In this illustration, the lamina and soft tissues are removed. The fifth illustration shows the bone graft harvested from the right hip through a separate incision. The sixth illustration shows the decorticated bone surfaces of the lateral spine and the placement of the right hip bone graft material from L4-5 for fusion.
