Ferris Smith Kerrison Punch up 5mm, 18cm

Clinical Application

This up-biting Kerrison punch is designed for controlled resection of small segments of bone and ligament in spinal and cranial procedures. Typical uses include laminectomy, foraminotomy, posterior decompression, microdiscectomy and targeted bone work around the neural foramen. The 5 mm bite size facilitates incremental removal of lamina and ligamentum flavum under direct visualization or microscopy, enabling precise decompression while minimizing collateral soft-tissue trauma.

Design & Configuration

The up-biting jaw orients the cutting edge toward the surgeon’s line of approach when working from a posterior or caudal trajectory, allowing bone to be removed in a cephalad/upward direction without repositioning the shaft. The 18 cm shaft length provides extended reach into deeper operative corridors while keeping the handle accessible outside the wound. The Ferris-Smith pattern is a widely used Kerrison geometry that balances bite control and visibility at the tip, supporting incremental nibbling of bone in confined spaces.
