Ferris-Smith-Kerrison Punch down 2mm, 18cm

Clinical Application

Designed for controlled removal of small segments of bone and ligament in spine and cranial procedures, this down‑biting Kerrison punch facilitates incremental resection of lamina, facet osteophytes, and ligamentum flavum during laminectomy, foraminotomy, microdiscectomy, and other decompressive procedures. The 2 mm bite provides fine, precise control for targeted work around neural elements where conservative, stepwise bone removal is required.

Design & Configuration

The down‑biting (punch down) geometry allows the working tip to engage tissue and bone beneath the plane of the shaft, which is advantageous when working under laminar overhangs or within narrow posterior approaches. An 18 cm overall length provides reach into deeper exposures and tubular retractors while maintaining tactile feedback. The small 2 mm bite enables incremental shavings of bone for precise contouring and minimizes risk of large, uncontrolled bone fragments in confined operative fields.
