Bone Rongeur: A Fundamental Need in Orthopedic and Neurosurgeries

Bone Rongeur: A Fundamental Need in Orthopedic and Neurosurgeries

 

Orthopedic and neuro-complications are diseases and injuries that badly affect our musculoskeletal system and nervous system respectively. These system includes bones, muscles, ligaments, tendons, joints, nerves, and other brain connective tissues. Any damage to these structures can turn into chronic orthopedic diseases or brain complications. Surgeons always in need of finding the best tools and instruments in order to fight these complications. These instruments are routinely used to perform small clinical practices in operating room surgeries. A bone rongeur is one of the most important instruments widely used for orthopedic surgeries. The term “rongeur” is derived from the French language that gives the meaning of “rodent” a reference to the action that it is designed to gnawing at bones or tissues. It is also used in combination with other tools to increase the surgical expectations at the surgeon’s best level. It is used for bone handling and manipulation. This versatile instrument makes surgeries easy where surgeons find difficulty in accessing the surgical site. Thus, it is important to understand the need for such instruments that will make surgeries faster and efficient. Ultimately, speed and efficiency will result in better results for the patients. 

 

Importance of bone rongeur in orthopedic surgeries 

A rongeur is considered a heavy-duty instrument with scoop-shaped and sharp-edged tips used for gouging out bones. It is widely used to open a window in bones and skull to access tissues underneath. It is not only used in orthopedic surgeries, but important for maxillofacial surgery, pediatric surgery, and neurosurgery. Some common uses are listed below:

  • Used to remove soft tissues or bony fragments in maxillofacial surgery
  • Used to cut traumatic amputated bone to allow the skin to be closed over the defect
  • Used to break through ribs during removal of the anterior chest wall in the cadaver dissection lab
  • Used it to crack it off the teeth or chip away the dental tartar. 

The uses are not just limited to the above list, but surgeons can use this incredible instrument according to their preferences.

Types of Bone Rongeur

Bone rongeur comes up with incredible designs and styles along with multiple types. Let’s have a look at different types of rongeur!

Ruskin

Ruskin Rongeurs are multipurpose surgical instruments and are commonly used in many surgical procedures that require bone handling. These instruments feature a scoop-type jaw that allows it to be used for clearing space or scooping out in bone to increase access to the surgical area or bone remodeling. It comes with multiple variations in styles and sizes such as rongeur with a length of 6" curved 2mm, curved 4mm, 5mm, 6mm, 7mm with a double-action, and many more. With the help of a strongly built-in structure, they are used for gnawing holes in bones during orthopedic surgical procedures.

Luer

Luer Rongeur is a highly versatile surgical instrument and is widely used in orthopedic surgical procedures. It is ideal for cartilage, bone repair, and grasping or handling bone segments to cut or gnaw away the tissues.

Stille Luer

Stille Luer Rongeur is well-suited for many orthopedic and neurosurgical procedures. It comes with different variations to accommodate the surgeons in a variety of surgical procedures. This instrument comprises purely high-grade German surgical stainless steel, thus making it ideal for gnawing away tissues. 

Blumenthal

It is an excellent instrument used for nipping and cutting away bone pieces during orthopedic surgical procedures. It comes with 45 angled beaks and 14.5cm in length. It features strongly curved tips that allow easy handling and manipulation during surgeries. Blumenthal pattern also features a double-spring plier handle with horizontal ridges. The double-action mechanism ensures the opening and closing of jaws. The ergonomic plier-style handle allows maximum control.

Kleinert-kutz 

It is an incredible surgical instrument well-suited for orthopedic surgical procedures. It is specifically designed for use in synovectomies where the synovial membrane is required to remove from synovial joints. Kleinert-kutz rongeur is also highly useful for use in the treatment of rheumatoid arthritis. It features the double-action mechanism and an incredible curvature that allow this instrument as a roundedness mirror of the joint and thus effectively grasp the soft layer without causing any tearing or ripping. 

Beyer

It is widely used in the handling and modification of bones. It features a debunking double-action hinged structure along with curved jaws that make this instrument ideal for many orthopedic surgeries. The jaws are slightly cup-shaped which provides additional grip. This incredible structure helps to enlarge holes via scooping. It is also used for the removal of sharp edges of the alveolar crest following tooth extraction. It features extraction pliers or forceps design terminating at the distal end along with sharp edges. The scoop-shaped jaws attach to a sprung and strong pivoted handle. When the handle is squeezed together, it closes the jaws that cut through the bone tissues. 

Friedman

It is strongly constructed with sharp-edges and scooped tips widely used for gouging out the bones during surgical procedures. Friedman pattern is preferably used to open the window in bones or the skull. It is well-suited for use in neurosurgeries and orthopedic surgeries in order to expose the surgical area under examination. It features a double-action mechanism that increases the force at the cutting site when maximum leverage is required for bone cutting. The delicate design makes them perfect that does not obstruct the visual of the operative field. It is ideal for plastic surgeries, neurosurgeries, and orthopedic surgical procedures. It comes in multiple variations with different patterns.

Echlin

It offers a wide range of benefits during surgical procedures. Echlin pattern is specifically designed to use in neurosurgical procedures such as laminectomy. The delicate design makes it perfect for neurosurgeries. 

Frykholm

It is used to bit off bone pieces during a wide range of surgical procedures. It features a compound action mechanism that allows strong gripping of bones during surgical procedures. It comes in a range of multiple variations to accommodate the surgeons in many medical approaches. 

Bacon Cranial

It is preferably crafted for neurosurgical procedures that need access to brain tissues or many other related areas. It can be used to create or chip away the window in the skull in order to get better visualization and access. The delicate jaws are slightly angled which allows the handle to remain comfortable and able to manipulate easily. 

Adson Cranial

Adson Cranial Rongeur is ideally used for neurosurgical procedures. It features 8mm wide jaws that make it perfect for grasping dense tissues or bony tissues. It is especially well-suited for craniotomies in which surgeons need to get better access to brain tissues through cranial procedures. Moreover, it is available in curved, straight, or rat tooth style.

Zaufal-Jansen

It is a highly versatile pattern used for modifying or cutting bones. It features a double-action mechanism along with strongly curved jaws. The curved profile minimizes the chances of any damage during blunt dissection or exploration of the surgical site. Moreover, the scoop-shaped design allows it to scoop out bony fragments or hard tissues during bone remodeling. 

Smith Peterson Laminectomy

It is widely used for many orthopedic or neurosurgical procedures. It is specifically designed for laminectomy procedures. It features a double-action joint and strongly curved narrow jaws that make this instrument perfect for many surgical procedures. 

Cleveland

It is a leading dental instrument used for specific dental procedures. Cleveland rongeur comes with multiple variations, in a length of 5 1/2" curved 4mm and 6 3/4" curved 4mm. The unique design of these instruments makes them perfect for dental procedures. They maximize the force at the cutting surface when cutting the bone with increased leverage.
