Ferris Smith Kerrison punch 3x5mm down ward

Clinical Application

This down-biting Kerrison is intended for precise removal of small segments of cortical bone and ligament in spine and neurosurgical procedures. The 3 x 5 mm bite allows controlled, incremental bone and ligament resection during laminotomy, laminectomy, foraminal decompression, and other decompressive approaches where working close to neural elements requires predictable bite size and limited excursion.

Design & Configuration

The Ferris-Smith pattern denotes a robust, surgeon-oriented geometry that balances tactile feedback with cutting strength. The down-biting (downward) orientation positions the cutting edge to excise bone when the instrument is drawn downward from the working surface, improving access in superior-to-inferior approaches or when working on the dorsal surfaces of laminae. A 3 x 5 mm bite offers a compromise between precision and efficiency: small enough for delicate work adjacent to dura and nerve roots, yet large enough to remove bone in a controlled number of passes.
