Kerrison Rongeur – 7″ (18 cm) | 2 mm 40° Up-Biting | Cervical Surgical Instrument

Kerrison Rongeur – Precision Cervical Decompression Instrument

The Kerrison Rongeur is a specialized surgical tool that spine surgeons use for removing bone, ligamentum flavum, and other compressive structures during cervical and lumbar spinal procedures. The instrument is designed to provide controlled bone removal in confined anatomical spaces, ensuring safe access to the spinal canal and neural structures.

The rongeur features a 7″ (18 cm) shaft that provides excellent reach and control in cervical and upper thoracic procedures. The 2 mm bite is specifically sized for delicate bone removal around the spinal cord and nerve roots. Furthermore, the 40° up-biting jaw is shaped to reach over the posterior edge of the lamina and bite upward, allowing the surgeon to decompress the neural elements from a posterior approach safely.

Key Features of the Kerrison Rongeur

• 7″ (18 cm) Length: For precise control in cervical and upper thoracic procedures.

• 2 mm Bite: For delicate bone and ligament removal.

• 40° Up-Biting Jaw: For safe access to the ventral aspect of the spinal canal.

• Thin Footplate: For insertion under the lamina with minimal dural retraction.

• Double-Spring Mechanism: For smooth, controlled cutting action.

• High-Grade Stainless Steel: Durable, corrosion-resistant, and fully autoclavable.

• Reusable and Autoclavable: For repeated clinical use.

Medical Applications

Surgeons select the Kerrison rongeur for cervical laminectomy, foraminotomy, discectomy, and spinal decompression procedures. The 40° up-biting jaw is particularly useful for removing bone from the ventral aspect of the cervical spine, where an up-biting angle provides better access than a standard straight rongeur.

Because precise control is critical when working near the spinal cord and nerve roots, the thin footplate and 2 mm bite help the surgeon maintain steady positioning during bone removal. For related spinal instruments, explore our Spinal Instruments or view our Foraminotomy Rongeur.

Durable Stainless Steel Design

Manufacturers construct the instrument from high-grade stainless steel, which resists corrosion and holds up across repeated sterilization cycles. The double-spring mechanism maintains consistent tension over time, ensuring reliable cutting performance. (Learn more about laminectomy from Wikipedia).

Handle the instrument carefully to protect the jaw cutting edges and footplate, as worn or damaged components may affect bone removal accuracy.
