Treatment of spinal deformities is an area of special interest for Dr. Alsina. He is very experienced in caring for patients with conditions that cause the spine to misalign, as in Scoliosis, and is especially passionate about this work.


This surgery corrects spondylolisthesis, in which fractured bones or weakened joints allow a disc to slip forward and pinch a nerve root. This often causes pain to radiate to the legs and feet through the sciatic nerve. Any bone that is pressing on a nerve is removed, and bone grafts are added to the side of the spine. The grafts are held in place with rods and screws. The grafts will eventually fuse into solid bone and keep the discs from further slippage.


To correct spinal curvature, a surgeon may perform a lumbar corpectomy. The procedure is done through the patient’s side, removing diseased or damaged discs and relieving pressure on the spinal cord. The surgeon will open up the vertebrae space, which reduces the deformity and allows for a straighter spinal alignment. A bone graft is inserted into the space vacated by the disc, and the surgeon uses a metal bridge, as well as metal bolts and screws to secure the graft and anchoring vertebrae in place. The graft fuses over time.
