External Fixators — Concepts
Types: uniplanar, biplanar, circular. Biomechanics: stiffness ↑ with larger pins, more pins, wider spread, closer frame. Indications: open fractures, polytrauma, infected nonunion, limb lengthening. Advantages: minimal soft tissue stripping, adjustability. Disadvantages: pin site infection, stiffness, bulky frame.
