What is K-wire insertion?
A Kirschner wire (also called a K-wire) is a thin metallic wire or pin that can be used to stabilize bone fragments. These wires can be drilled through the bone to hold the fragments in place. They can be placed percutaneously (through the skin) or can be buried beneath the skin.
Is K-wire an implant?
K-wires and Steinmann pins are used to provide internal fixation for fractures or osteotomies. In some instances, removal of the implant is planned and the implant is left long to facilitate its removal. In other instances, implant removal is not planned and the implant is cut off at the level of the bone.
What is the difference between a Steinmann pin and a K-wire?
The difference between pins and k-wires is mainly diameter: IM pins—also referred to as Steinmann pins—are between 1.5 mm (1/16 inch) and 6.5 mm (1/4 inch) in diameter, while K-wires are 0.9 to 1.5 mm (0.035, 0.045, 0.062 inches) in diameter.
How long can K-wires be left in?
The K wires are generally left in place for an average of 2 to 3 weeks. When the fracture is not tender to firm palpation between a thumb and index finger, the K wires can usually be removed; this is a clinically healed fracture.
Does K-wire removal hurt?
The removal of K-wires is usually very quick – each wire removal only takes one to two seconds. Your child may feel tugging, along with some very brief discomfort. Young patients who have had the procedure usually say ‘it wasn’t too painful’ or ‘it’s OK, it’s just a little sore’.
Can K-wires be left in?
K-wires can be buried and left in situ until union or they can be left unburied and require removal after four weeks, with plaster immobilisation until union.
Can you walk after K-wire removal?
At 6 weeks, the K- wire is removed and the foot can then be placed in normal footwear and normal bathing can be resumed. The toe joint will not bend after this procedure.
Are K-wires considered internal fixation?
Placement of Kirschner wires (K-wires) is the most common form of surgical fixation, with open reduction and internal fixation (ORIF) being the second most common method.
Who invented K-wire?
The original Kirschner wire was introduced in 1909 by the German surgeon, Dr Martin Kirschner (1879-1942) 2. Both wires/pins were at first used for traction and only began to be used for fixation in the 1930s.
How do I know if my pins are infected?
Check your pin site every day for signs of infection, such as:
- Skin redness.
- Skin at the site is warmer.
- Swelling or hardening of the skin.
- Increased pain at the pin site.
- Drainage that is yellow, green, thick, or smelly.
- Numbness or tingling at the pin site.
- Movement or looseness of the pin.
What are K-wires made of?
Kirschner wires or K-wires or pins are sterilized, sharpened, smooth stainless steel pins. Introduced in 1909 by Martin Kirschner, the wires are now widely used in orthopedics and other types of medical and veterinary surgery.
Are K-wires MRI safe?
Conclusions: Implant-quality stainless steel traction pins show no signs of adverse heating or pin migration when subjected to 1.5-T MRI clinical scanning. Kirschner bows are highly ferromagnetic and should not be used unless individually tested for safety.
How is K-wire removed?
The K-wires stick out of the skin so that they can be easily removed once the bone has healed. They are covered with a dressing and a plaster cast and you / the patient will not be able to see them; alternatively they may be exposed out of the toe/finger. The K-wires can usually be removed in the Outpatient Department.
How do they wire a broken finger?
This involves holding broken bone fragments together using small, sharp wires passed through the skin into the bones using x-ray control. The bones are first pulled into the right position (manipulation under anaesthesia). The wires are cut off outside the finger and bent over so they don’t catch too much.
What happens after pins are removed?
Once all the pins are removed, the staff will apply a bandage and wrap. Your child will get another splint or cast if needed. If there is a splint, it may be removable. If it is, follow the staff’s instructions.
