L4-5, L5-S1 Spinal Injuries with Subsequent Surgical Fusions
This stock medical exhibit depicts L4-5 and L5-S1 spinal injuries with subsequent surgical fusions in a series of illustrations. The first illustration shows the pre-operative condition in a mid-sagittal view of the lumbo-sacral spine. In it, disc herniations are seen at L4-5 and L5-S1, causing compression of nerve roots. The second illustration shows the pre-operative condition in a superior view of the herniated disc causing compression of the nerve root. The third illustration shows the beginning of the discectomy procedure: anterior incisions are made, exposing the interspaces and the iliac crest. Cancellous bone grafts are harvested from the left iliac crest. The fourth illustration depicts a sagittal view of the lumbo-sacral spine, showing the removal of the L4-5 and L5-S1 herniated discs. The fifth illustration shows an anterior view of the lumbar spine, showing the filling of BAK cages with bone grafts and insertion of the cages into the interspaces for fusion. The sixth illustration depicts a sagittal view of the post-operative condition of the fusion, showing the BAK cages and cancellous bone grafts in place.
