General Orthopedic Instruments: A Complete Guide

General Orthopedic Instrument

Orthopedic surgery is a procedure that addresses issues that affect the musculoskeletal system, which consists of joints, bones, muscles, tendons, and ligaments. It is vital in treating joint disorders, deformities, and injuries resulting from trauma. The core of any successful orthopedic surgery is an effective set of common orthopedic tools that aid the surgeon in performing accurately, effectively, and securely.

This thorough guide covers all you must know about orthopedic instruments, the kinds used, their functions, how they are utilized in surgery, and their effect on surgery's success. If you're a medical student or nurse, surgical tech, or orthopedic professional, this guide will give you an excellent foundation for the tools used in the modern practice of orthopedics.

1. Introduction to Orthopedic Instruments

Orthopedic instruments are specially designed to cut, shape, or hold joints and bones. They typically include:

• Stronger and more durable than other surgical instruments
• Made from surgical-grade stainless steel or titanium
• Built to withstand the force of high-force applications

They are crucial in processes like:

• Repair of a fracture (ORIF - Repair of Fractures (ORIF - Reduction Internal Repair)
• Reconstruction and repair of joints (arthroplasty)
• Arthroscopy
• Surgery for the spine
• Amputation

The correct selection and use of instruments could significantly affect surgical precision, speed, and patient outcomes.

2. Categories of General Orthopedic Instruments

Instruments used for orthopedic surgery can be classified into functional categories according to their role in surgical procedures.

A. Cutting Instruments

They are tools employed to cut through tissue such as cartilage or bone.

• Bone Saws, available in both powered and manual versions, cut through bone during amputations or joint replacements.
• Osteotome: A chisel-like tool that is used in conjunction with a mallet to cut or form bone.
• Bone Chisel The chisel is wider and more abrasive than osteotomes, making it ideal for shaping or splitting bones.
• Rongeur The HTML0 Rongeur is a heavy-duty forceps with sharp edges used to nip or bite away at the bone.
• Curette: A spoon-shaped device to scrape bone or remove tissues from bone joints or cavities.

B. Grasping and Holding Instruments

It is useful to keep the bones or tissues in a certain position.

• Bone-holding forceps Instruments such as Lane, Verbrugge, or Lowman forceps can hold and stabilize bones while drilling or fixing.
• Tissue Clamps are used to hold tissues or drapes.
• Needle Holders: Secure needles for suturing tissues during closure.

C. Retracting Instruments

These tools assist in pulling back soft tissues, allowing greater visibility and easier access.

• Hohmann Retractor is widely employed in joint operations to retract soft tissues and expose the surgical site.
• Gelpi Retractor Self-retaining that has pointed tips. Perfect for cutting deep holes.
• Weitlaner's Retractor Self-retaining is utilized for small or superficial incisions.
• Czerny Retractor Double-ended retractor designed for soft tissue retractors.

D. Drilling and Reaming Instruments

It is used in procedures that require the use of implants such as pins, screws, or nails.

• Drill Bits Drill bone pilot holes.
• Drilling Guides: Check for precision and correct angle.
• Reamers Solid or hollow tools are used to expand canals or prepare surfaces.
• Manual or power Drill motorized options are available based on the method used.

E. Fixation Instruments

These instruments aid in the placement of implants when undergoing internal fixation procedures.

• Screwdrivers (AO, cruciform, Hex): Used for inserting bone screws.
• Bone Taps Cutting internal threads in the bone to allow to allow screw for the screw.
• Depth Gauges Take measurements of the length of holes drilled to determine the screw sizes.
• Plate benders Contain bone-shaped metal plates to fit bone shapes.
• Wire cutters and twisters are used to manage cerclage wires.

F. Measuring and Alignment Instruments

It is used to ensure symmetry in surgery and alignment.

• A goniometer is a device that measures joint angles.
• A caliper is used to measure lengths and distances among bony points.
• Alignment Rods help verify the alignment of limbs in fracture rehabilitation or joint replacement.

3. Common Orthopedic Instruments and Their Uses

This is a comprehensive review of some commonly utilized orthopedic tools and their purpose:

1. Lane Bone Holding Forceps

• Separates the periosteum (bone liner) from the bone
• It is commonly used for the treatment of fractures and implants.

4. Depth Gauge

• Determines the depth of the bone hole
• This ensures that the screw length is selected accurately.

5. Reduction Clamp

• Align the bone fragments to fix them.
• It may have a temporary, semi-permanent, or permanent effect based on the course of treatment.

4. Specialized Instrument Sets for Orthopedic Procedures

A. Fracture Fixation Kit
