Bone cutting is challenging because bone is the hardest tissue in the body. Precision is crucial for proper healing. The wrong instrument can damage surrounding soft tissues and delay healing. Therefore, knowing the specific instrument used to cut bone is important for successful patient outcomes and speedy recovery. In this blog, we explore the main instruments used to cut bone, their functionality, and their importance in bone cutter surgery.
What are Bone Cutter Surgical Instruments?
Bone cutter surgical instruments are made to cut, shape, or remove bone with precision. These heavy-duty instruments withstand the high force needed to penetrate hard tissues. They also help prevent tissue trauma and give controlled bone manipulation for procedures like fracture repair, bone resection, amputations, and grafting.
Types of bone cutter surgical instruments
Several types of bone cutters are available. Surgeons choose instruments based on surgical preference and the type of bone involved. Here are some common instruments used to cut bone in modern surgery:
Bone Cutting Forceps
Bone cutter forceps have strong, serrated jaws for cutting bones during procedures that need precision. They are used in many orthopaedic specialties, such as joint reconstruction and maxillofacial procedures. One widely used type is the Liston bone cutting forceps which is used to cut or divide hard or thicker bones for resection or shaping.
Bone Saws
Bone saws are used for large osteotomies or for cutting bone grafts. They provide steady, clean cuts through dense bone with little effort. Some common bone saws used are:
Satterlee bone saw: features a wide, large blade with a slender profile for controlled cutting of large, dense bones in various reconstructive procedures. Also, the blades move in a push-pull motion that is ideal for making long, straight cuts, especially during knee replacement procedures.
Amputation saw: ideally used to cut through bone and cartilage. This tool is mainly used for removing limbs or parts of limbs due to infection, severe trauma, or other diseases (e.g., gangrene).
The Gigli Saw: features a flexible twisted wire and loops. It allows precise, controlled cutting of bones in confined spaces during realignment, fracture treatment, and fixation.
Bone Rongeurs
Bone rongeurs are heavy-duty, spring-loaded instruments with scoop-shaped tips. They bite away small pieces or fragments of hard bone. There is a wide range designed for specific surgical requirements. Some commonly used bone rongeurs include:
Kerrison Rongeur: featuring a sharp, thin, footplate design for easy insertion between the bone and dura to remove small fragments of the lamina or vertebrae during neurosurgery or spinal procedures.
Ruskin Rongeur: features a compound-action mechanism with sharp, scoop-shaped tips to cut, scoop, and remove bone fragments or tough tissues, especially in tight spaces.

Bone Osteotome
Bone osteotomes have a bevelled edge on both sides. This allows them to cut straight down into bone without damaging nearby areas. These tools are used to cut, reshape, or compress bone tissue in many procedures, including dentistry, orthopaedics, and plastic surgery. A widely used one is the Hibbs Osteotome, which creates space for bone grafts during bone fusion and spinal stabilization.
Bone Chisel
Bone chisels feature a single atraumatic bevelled blade for efficiently cutting, carving, shaping, and removing bone tissue or removing malfunctioning implants. Moreover, a wide range of bone chisels is available that assist surgeons in bone cutting, recontouring margins, splitting of bones, and removing impacted teeth in dental, maxillofacial, and orthopaedic procedures.
Bone Gouges
Bone gouges are crucial for shaping or removing soft bone. This helps improve access to confined surgical areas. The Swan Neck gouge has a curved swan neck blade that helps reach deep areas and shape or remove soft bone parts.
Bone Drill/Burr
Bone drills and burrs are useful for creating holes for screws or plates. They also cut bone in a controlled, local area. Additionally, these tools are used for perforating bone or creating burr holes in the skull for neurosurgery and orthopaedic procedures. Here are the most common types:
Hudson hand drill: a manual instrument used to create precise burr holes into the skull to release the pressure caused by the blood or fluid after a brain bleed or traumatic injury. Moreover, it also assists surgeons in performing the craniotomy procedure with maximum control.
Caspar drill guide: features a hollow tubular end for safely guiding the drill bit for the precise placement of distraction pins, especially during cervical spine surgeries. Also, it enhances the disc space visualization and ensures a slip-free fixation on the vertebral bone surface.
Conclusion
Bone cutter instruments are indispensable tools in modern surgery. These tools offer a range of options to suit multiple surgical procedures that involve bone cutting. From delicate bone cutting forceps to heavy-duty rongeurs, each tool serves a critical purpose in reshaping or removing the bones. Also, choosing the right bone cutter instrument allows surgeons to perform complex procedures with utmost precision and safety that the patient deserves.
FAQ’s
Can bone cutter surgical instruments be reused after performing bone fixation procedures?
Yes, bone cutter surgical instruments are reusable if properly sterilized after each procedure. For tools with hooks, hinges, or locks, use a micro-brush to remove debris and bioburden. For more information on sterilization methods, check our blog.
