What is kirschner or K wire?

-
A Kirschner wire or K wire is a thin wire or pin that is used to stabilize bone fragments. These wires can be drilled through the bone to hold the fragments in position. They can be placed percutaneously through the skin or can be buried in the skin.
K-wires are available in different sizes, and they become less flexible as they increase in size. These wires are often used to stabilize a broken bone and then removed when the fracture has healed. The wires can be also threaded to help in the prevention of movement or backing out of the wire, although that can also make them more difficult to remove. 

K-wires are most commonly used when traction was a common treatment for certain types of fractures. When traction is K-wire is mostly inserted into a bone to provide a rigid anchor to the bone, and then the weight is pulled on the bone through the wire to pull the broken extremity into alignment. 

Complications with Pins 

There are some complications associated with the use of K-wires: 
  • Infection: The location of pin insertion can be a source for infection to enter the human body. If left through the skin, bacteria can spread along the pin tract and get deeper into the body, and possibly to the bone. Due to this reason, patients with k-wires that are left exposed are typically instructed on techniques for pin care to prevent infection. 
  • Breakage: Pins can provide stable fixation of a fracture, but most pins are comparatively thin in diameter and they can break if there is insufficient fixation to support the broken bone. 
  • Fracture Movement: K-wires generally provide less rigid fixation of fractures in comparison with some other techniques such as plates and screws, and metal rods. So, sometimes it is possible for the fracture to shift its position when only K-wires are used for fixation. 
  • Migration: Pin migration is a one of the most concerning complications. Due to this reason, extreme care must be used especially when using K-wires in the abdominal area or chest. There are case reports of placing K-wires in bones around the shoulder only to find them migrating into the chest cavity after weeks or months. 
Pin Removal

Mostly, K-wires are removed after some time the bone has healed sufficiently. There are exceptions if the wire is buried deep inside the bone, but most of the pins are removed once healing is complete (or at least when the broken bone is stable). The smooth pins can often be removed without special anesthesia. For most of the patients, pin removal should not cause too much discomfort. However, pins that are under the skin, threaded K-wires or pins that are otherwise hard to remove may have to come out in an operating room under an anesthetic. 

There are a number of manufacturers in the market who manufactures and supplies the Kirschner wires or K-wires. Siora Surgicals Pvt. Ltd. is one renowned manufacturer and supplier of orthopaedic implants including K-wires.

Benefits of Partial Hip Replacement

-
Image
Partial hip replacement surgery is a procedure that replaces haft of the hip joint, specifically the ball of the femur (also called the femoral head) with a prosthetic or artificial joint. The procedure, which is also known as hip hemiarthroplasty, is totally different from total hip replacement surgery, which replaces both with the socket and femoral head. A partial hip replacement surgery using orthopedic tools is more commonly used to treat traumatic hip injury and is usually prescribed to elderly patients whose bones are more brittle and prone to fractures even with mild slips and falls. In the meantime, degenerative conditions typically need a total hip replacement since both the socket and ball have to be replaced in such cases.

Fibula Fractures: Types, Symptoms & Treatment

-
Image
A fibula fracture refers to a break in the fibula bone. A forceful impact, such as landing after a high jump or any impact to the outer part of the leg, can cause a fracture. Even spraining or rolling an ankle puts stress on the fibula bone, which can lead to a fracture. Types of Fibula Fracture Fractures in Fibula can happen at any point on the bone and can differ in type and severity. Types of fibula fracture include: Lateral malleolus fractures occur when the fibula is fractured at the ankle Fibular head fractures occur at the upper end of the fibula at the knee Avulsion fractures happen when a small chunk of bone that is attached to a ligament or tendon is pulled away from the main part of the bone Stress fractures describe a condition where the fibula is injured as the result of repetitive stress, such as hiking or running Fibular shaft fractures occur in the mid-portion of the fibula after an injury such as a direct blow to the area Fibular shaft fractures occu...

Overview of Orthopedic Screw Drivers

The screwdrivers had to retain screws securely until they were anchored in place, offering an easy to use alternative for orthopedic surgeons who currently employ a variety of surgical devices to retain bone screws, which tend to be overly difficult, complex to use and hard to manufacture by the  orthopedic instrument manufacturers .   The initial brief was to develop a range with interchangeable shafts for fixing 1.5, 2.5 and 3.5 mm screws with hexagonal heads. Theoretical and practical studies resulted in a decision to develop a separate design to enhance the capabilities of the 1.5 mm device to achieve the torque used to tighten orthopedic screws. The pre-production prototype consists of three parts- a shaft, a sleeve and handle- manufactured from different grades of stainless steel to ensure resistance to corrosion and ease of disassembly to allow sterilization. The shaft is attached to the handle using coupling- a universal coup...
