What are the types of external fixator?
External fixators provide fracture fixation based on the principle of splinting. There are three basic types of external fix- ators: standard uniplanar fixator, ring fixator, and hybrid fixator.
What is a Monoplanar external fixator?
The frame of a uniplanar external fixator consists of at least two pins in each main fracture fragment connected with one single rod. A second rod may be added to increase stiffness of the frame. Details of external fixation are described in the basic technique for application of modular external fixator.
What is a multiplanar external fixator?
Multiple fractures may require several pins and rods, also referred to as multiplane external fixators. The external rods are kept as close to the skin as possible, but should also allow access to open wounds for treatment.
What is Hoffmann external fixator?
The Hoffmann 3 Modular External Fixation System is used to provide stabilization of open and/or unstable fractures and where soft tissue injury may preclude the use of other fracture treatments such as IM rods, casts, or other means of internal fixation.
What is a spanning external fixator?
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.
What is hybrid external fixation?
Principles of hybrid external fixation By bridging from the epiphysis to the diaphysis, the fixator stabilizes the metadiaphyseal region. A ring fixator may be useful to hold complex proximal fractures, and attached to the tibial shaft with pins and rods (hybrid fixation).
What is a Stryker external fixator?
External Fixation System. Used to provide stabilization of open and / or unstable fractures and where soft tissue injury may preclude the use of other fracture treatments.
What is external fixation for dogs?
External Fixation is an effective procedure to correct complex fracture and angular limb deformities in dogs.
Can an external fixator be used to reduce comminuted fractures in dogs?
Objective: To describe a technique for closed reduction of and application of a type-II external fixator to comminuted fractures of the radius and tibia in dogs and to evaluate outcome of the technique in a series of client-owned dogs. Design: Retrospective case series.
What is an external fixator?
External fixation is completed using a device called an external fixator. This specialized device consists of multiple pins and external bars or rings, which hold a fractured bone in place during the healing process. An external fixator is used primarily for complex fractures or fractures paired with an external wound.
What is the frame of a fixator called?
The combination of pins, clamps, and connecting bars create the external skeletal fixator frame (the entire apparatus) (Figure 44-1). Collectively, the frame and the transfixed bone are referred to as a construct or montage.
