A Kirschner pin (K-wire) is an orthopedic fixation device, commonly used to treat fractures, especially those with low stress or in pediatric patients. This article provides a comprehensive guide for suppliers to buy Kirschner needles from a definition, application, material, efficacy and buyer's shopping perspective.
Definition of Kirschner pin
Kirschner wire is a commonly used orthopaedic internal fixation material, invented by Dr Martin Kirschner. It is commonly used for fixation of fracture fragments, especially short fractures or avulsion fractures with little stress, and for temporary fixation of fracture fragments during orthopaedic surgery. Kirschner pins are usually about 20cm in size and are available in different sizes ranging from 0.5 to 4mm in diameter.
The use of Kirschner pins is very wide, not only limited to fixation of fractures, but also used in bone traction, as guides, and to assist in surgical operations. In the treatment of fractures in children, Kirschner pins are widely used because of their low impact on epiphyseal growth and ease of handling.
The technique of using Kirschner's pin includes fixing the fracture in an anatomical position with a Kirschner's pin, drilling holes perpendicular to the longitudinal axis of the phalanx at the proximal and distal ends of the fracture, and inserting wires for compression fixation, which is a very secure fixation method that is favourable for early postoperative exercise and functional recovery.
The history of Kirschner's pin dates back to 1907 and was first used by the Swiss physician Fritz Steinmann, and later refined by Dr Martin Kirschner to make it more refined and practical. During World War II, the widespread use of Gram pins and the use of antibiotics and anti-corrosive materials reduced infection rates and made them an indispensable tool in orthopaedic surgery.
As a common orthopaedic internal fixation material with a variety of sizes and uses, Gram pins are an important tool for orthopaedic surgeons when dealing with fractures and other orthopaedic problems.
The efficacy and function of Kirschner's pin
Kirschner's pin is one of the most commonly used internal fixation materials in orthopaedics, which is made of two kinds of materials, namely stainless steel and titanium alloy.
Kirschner's pins are widely used in orthopaedic surgery, with the advantages of small trauma and cheap price. In terms of adult fractures, Kirschner's pins can fix fractures of short and small bones, such as metacarpal, metatarsal, phalangeal and other fractures.
Common avulsion fracture or tension fracture in orthopaedics, often use Kirschner's pin and wire co-fixation, at the same time in orthopaedic surgery, for the comminution of serious complex fracture, such as heel fracture, tibial plateau fracture, etc., will also use Kirschner's pin for temporary fixation, or the use of Kirschner's pin prying auxiliary repositioning.
For children, due to the growth and development period, the epiphysis has not yet closed, if a fracture occurs and requires surgical treatment, usually use Gram's pins for fixation, this is because Gram's pins have a small impact on the epiphysis, and generally will not affect the development of the child's bones.
For open fractures, Gerber pins are also used when fixating with an external fixation brace.
Gerber pins are used for a variety of purposes in orthopaedic surgery, including the following:
Fracture fixation: Gram pins are mainly used to fix fractures with little stress such as short fractures or avulsion fractures, and are also often used to temporarily fix fracture blocks during orthopaedic surgery. It can be used to fix fractures of the hand, foot and other parts of the body.
Joint fusion: Gerber pins can be used in joint fusion surgery to help fix the joint in the desired position.
With external fixation bracket: The Gerber pin is an important part of the circumferential external fixation bracket and is used to fix fractures with high stress such as pelvic fractures and heel fractures.
Temporary fixation and guide pins: Kirschner pins are often used in surgery to temporarily fixate a fracture block for subsequent placement of a plate or other internal fixation. At the same time, Kirschner pins can also be used as guides to facilitate the placement of internal fixations such as hollow screws and Herbert screws.
Fracture Reduction: GROB pins can be used for fracture reduction by prying the laterally displaced fracture end into place.
Fracture treatment in children: Gerber pins are widely used in fracture treatment in children because they have little effect on epiphyseal growth.
Bone traction: Kirschner's pins are used in bone traction techniques, such as heel traction and tibial tuberosity traction.
Gram's pin plays an important role in orthopaedic surgery because of its easy operation, small trauma, good stability and other characteristics.
Difference between Kirschner pins and intramedullary nails
Kirschner pins and intramedullary nails are two common orthopaedic internal fixation materials that differ significantly in their structure, mode of use, indications and biomechanical properties. The following are their main differences:
Characteristic |
Kirschner Pin |
Intramedullary Nail |
Structure |
Thin wire (0.5-4 mm diameter) |
Larger, solid rod |
Use |
Short fractures, temporary fixation, and pediatric use |
Long bone fractures, especially with high stress |
Biomechanical Strength |
Low, for small bones or low stress fractures |
High, for larger, more complex fractures |
Surgical Application |
Fracture fixation, joint fusion, temporary fixation |
Fracture stabilization in long bones |
Material |
Stainless steel or titanium |
Stainless steel, titanium, or composite materials |
Procedure |
Minimal, often percutaneous |
More invasive, requires surgical exposure |
In summary, Kirschner pins and intramedullary nails each have their own characteristics and applicable scenarios in orthopaedic treatment, and the choice of which fixation method to use depends on the type, location, and severity of the fracture, as well as the overall condition of the patient.
Kirschner's needle purchase advantages
Kirschner needles have a wide range of applications in orthopaedic surgery, and the advantages of their purchase are mainly reflected in the following aspects:
Less traumatic: Gram pins have a smaller diameter, usually between 0.5 and 4 mm, which makes them less damaging to tissues during surgery, helping to reduce surgical trauma and post-operative pain for patients.
Inexpensive: GERN needles are relatively inexpensive, which helps to reduce the cost of the procedure and the financial burden on the patient.
Flexibility: Kirschner pins are available in a variety of sizes and materials, including stainless steel and titanium, etc. Different diameters and lengths of Kirschner pins can meet the treatment needs of different parts and types of fractures.
Adaptable: Kirschner pins are not only suitable for adults, but also particularly suitable for the treatment of children's fractures, as they have less impact on the epiphysis and will not affect the development of children's bones.
Stable fixation: Gerber pins provide sufficient stability to facilitate fracture healing, especially when used in combination with tension bands or other fixation devices.
Simple operation: Gerber pins are relatively simple to operate and take less time to perform, which helps to reduce the risk of surgery and the patient's recovery time.12345
In summary, the advantages of Kirschner's pins in orthopaedic surgery purchase include less trauma, cheap, flexible, adaptable, stable fixation and simple operation. These advantages make Kirschner pins a common tool for orthopaedic surgeons when treating fractures.
Purchasers buy Kirschner needles mainly concerned about what
When purchasers are purchasing Kirschner needles, they mainly focus on the following aspects:
Specification and quality: The specifications of Grammell needles include length and diameter, and these need to be chosen according to the specific surgical needs. In addition, the quality of the Gramoxone needles is key, and it needs to be ensured that they meet medical standards and can be used safely and effectively in surgery.

By focusing on these aspects, purchasers can ensure that they are sourcing Gramoxone needles that meet their requirements, and that the sourcing process is economical and efficient.
Market Price of Kirschner Needles
The price of Kirschner needles varies depending on the brand, material, quality and specifications.
Price Range:
- Titanium K-wires: Around $137 USD
- Imported Kirschner pins: $437 - $546 USD
How to choose the diameter and length of Kirschner needles?
The choice of diameter and length of the Kirschner pin depends on the type and location of the fracture as well as the patient's specific situation. Below are some general principles for choosing the diameter and length of a Kirschner pin:
Choosing Diameter and Length
- Small fractures (e.g., hand, foot): 0.5-1.5 mm diameter, short length.
- Large or complex fractures (e.g., tibial or humeral): 2-3 mm diameter, longer length.
- Pediatric Use: Use smaller, thinner pins to avoid affecting bone growth.
Patient specifics
Children with fractures usually use thinner, shorter Kirschner pins due to the smaller size of the bones.
Adults with fractures may need to use thicker, longer Kirschner pins to provide adequate stability.
Surgical requirements
Gerber pins are sometimes used in conjunction with other fixation devices (e.g., external fixation frames), and compatibility with these devices needs to be considered in the selection of Gerber pins.
Biomechanical considerations
The diameter and length of the pin needs to provide sufficient biomechanical stability to facilitate fracture healing while avoiding unnecessary damage to surrounding tissues.12345
When selecting the diameter and length of the Kirschner pin, the orthopaedic surgeon will determine the most appropriate size of the pin based on the patient's specific condition and the characteristics of the fracture, combined with imaging such as X-rays or CT scans.
Summary
Kirschner pins are a versatile, cost-effective, and minimally invasive option for orthopedic surgeons when treating fractures. They are particularly valuable for small bone fractures, pediatric use, and situations requiring temporary stabilization. Despite being less biomechanically strong than intramedullary nails, they provide sufficient stability for low-stress fractures, are easy to use, and reduce surgical trauma. By considering these factors comprehensively, procurement can better assess the capabilities of potential Kirschner pin suppliers and make more informed decisions.
