Supplies multiple Kerrison punch angles for comprehensive spinal canal decompression during multilevel laminectomy and foraminotomy. The set allows the surgeon to switch between up-biting and down-biting configurations without leaving the operative field during C3–T1 and L2–S1 decompression. Neurosurgical teams standardize on this set for elective and emergency disc herniation surgery.

Used exclusively for spinal decompression procedures where progressive removal of lamina, facet, and ligamentum flavum requires sequentially larger Kerrison bites. The decompression punch set is organized by bite width so the surgeon can escalate from 2 mm to 5 mm punches as the canal is widened. It supports the systematic over-the-top decompression technique for lateral recess and central canal stenosis.

Combines Kerrison punches with pituitary rongeurs for removal of extruded disc fragments and epidural scar tissue during revision discectomy. The pituitary rongeur grasps soft disc material ventral to the thecal sac while Kerrison punches handle bony stenosis at the same operative level. Revision spine surgeons use the combined set when re-operating on recurrent herniations at the same segment.

Dedicated up-biting Kerrison set for caudal-to-cranial bone removal during cervical laminoplasty and lumbar laminectomy where the footplate must slide under the lamina from below. Each instrument in the set provides a different shaft length for shallow cervical and deep lumbar applications. Spine residents train with this set to master the footplate insertion technique without dural injury.
