What is a knee spanning external fixator?
A joint-bridging external fixator is fixed to the femur and the tibia while the fracture zone is left virtually untouched (it is bridged). Provisional reduction is achieved with distraction. When external fixation is used to bridge the knee joint it is always only for temporary fixation.
What are external fixators made of?
Circular external fixators can completely or partially encircle the arm, leg or foot that is being treated. These fixators are made up of two or more circular rings that are connected by struts, wires or pins.
What are methods of external fixation?
There are three basic types of external fix- ators: standard uniplanar fixator, ring fixator, and hybrid fixator. The numerous devices used for internal fixation are roughly divided into a few major categories: wires, pins and screws, plates, and intramedul- lary nails or rods.
What is Ilizarov technique of external fixation?
The Ilizarov apparatus is a type of external fixation used in orthopedic surgery to lengthen or reshape limb bones; as a limb-sparing technique to treat complex and/or open bone fractures; and in cases of infected nonunions of bones that are not amenable with other techniques.
Where is the Pilon bone?
A pilon fracture is a type of break of the shinbone (tibia) that happens near the ankle. Most of the time, it includes breaks in both the tibia and fibula of the lower leg. The lower ends of these bones make up part of the ankle. The term “pilon” comes from the French word for pestle.
What is multiplane external fixation?
External fixation systems are devices made of metal rods, wires, and pins designed to provide stability to fractured leg bones. There are several types, but the most common are uniplane and multiplane systems. The human body has an amazing ability to heal itself, especially with regards to fractured bones.
What metal is used to fix broken bones?
The metal parts that are used to fix broken bones are made of stainless steel or titanium.
What type of metal is used for bone plates?
Materials involved in bone-plate design. The biocompatible materials used for bone plates are: stainless steel (SS), cobalt base alloys, bioceramics, titanium alloys, pure titanium, composite materials, and polymers (non-resorbable and bioresorbable).
How do you install an external fixator?
In an external fixator, metal pins or screws are placed into the bone through small incisions into the skin and muscle. The pins and screws are attached to a bar outside the skin. Sometimes day to day activities can seem more challenging when you have an external fixator.
What is an external fixator device?
Overview. An external fixation device may be used to keep fractured bones stabilized and in alignment. The device can be adjusted externally to ensure the bones remain in an optimal position during the healing process. This device is commonly used in children and when the skin over the fracture has been damaged.
Is Ilizarov surgery safe?
The Ilizarov device is a safe tool for limb lengthening in individuals of short stature when applied with the authors’ maximum stability technique.
How do you use a knee span fixator?
A single long bar or smaller crossing bars from each segment can be used to span the knee joint, ensuring that no radiopaque clamps overlie the joint line. The fixator should be locked into a slight amount of flexion, measuring approximately 5° to 15°.
What is FastFrame knee spanning fixator?
The FastFrame External Fixation System – Knee Spanning is a single-use external fixator consisting of the following components that are manipulated by the end user: clamps, telescoping rods, and half-pin bone screws (Figure 1).
What is the Synthes large external fixation system?
The Synthes Large External Fixation System is intended to provide treatment for long bone and pelvic fractures that require external fixation. Specifically, the components can be used for:
What is a joint-spanning external fixator?
Principles of joint-spanning external fixation Joint-spanning external fixation of the wrist may be used as a temporary or definitive treatment in simple or complex distal forearm fractures. The external fixator may be used on its own or to supplement K-wire fixation.
