How do you place a distal femur traction pin?
Distal femoral traction pins were placed with the specimen in a supine position, the knee flexed and supported to 45°, and the patella facing directly anterior. The sharp end of a 1.6 mm (mm) smooth Kirschner wire was used to pierce the skin of the medial distal thigh, at the level of the proximal pole of the patella.
What is a femoral traction pin?
Skeletal traction via a femoral or tibial traction pin assists in the reduction and transient stabilization of acetabular fractures with or without concomitant hip dislocation, pelvic vertical shear injuries, foreshortened femoral shaft fractures, and other pelvic, hip or femur injuries where splinting is not effective …
Where do you put a traction pin?
Note: Due to the risk of injury to the peroneal nerve, it is recommended to place the traction pin from lateral to medial. Connect the pin with an appropriate traction stirrup. It is important that the stirrup be freely mobile around the traction pin, to prevent rotation of the pin within the bone.
What is a traction pin?
It’s a system where a combination of pulleys, pins, and weights are used to promote the healing of fractured bones. These are usually in the lower body. In skeletal traction, a pin is placed inside your bone. That pin provides a base for a pulley system.
What is a Steinmann pin used for?
Steinman pins are used for skeletal traction of femoral fractures. The pin is inserted into the proximal tibia; a stirrup is attached and the desired traction applied. The pin is inserted in the normal manner.
When do you use a traction pin?
The placement of pins in the lower extremity for the purpose of skeletal traction is a basic skill required by an orthopedic surgeon. These pins are primarily used for the management of fractures and dislocations.
How do you apply femoral traction?
Position any leg support straps as directed (eg, 2 above the knee and 2 below). Apply longitudinal traction on the ankle to straighten and lengthen the shortened leg to the length of the contralateral leg. Use about 10% of the patient’s body weight or up to about 7 kg (15 pounds). Lock the device in place as directed.
Is a Steinmann pin an implant?
Steinmann Pins are generally made from implant-grade stainless steels. These pins typically have trocar, chisel, or spherical ends. Steinmann pins can have partially threaded or smooth outside diameters.
What is the difference between a Steinmann pin and AK 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.
