摘要:

SummaryThe technical strategies to treat fractures of the tibia with Ilizarov fixators are described. An Ilizarov fixator can be applied as a neutralization device after open or pericutaneous reduction, as an active reduction device using universal hinge mechanisms between fixation blocks, or as an external scaffold which incorporates distraction/compression and the placement of pins and wires to apply force through pivot points and levers. Periarticular fracture patterns are classified into five types: Type 1, intact metaphysis; Type 2, simple sagittal or coronal fractures; Type 3, moderate large fragment joint fractures; Type 4, comminution of the joint; and Type 5, severe crushing with bone loss. The concept of fixation blocks and orthogonal placement of pins and wires is introduced.

摘要:

SummaryThe anatomy of the proximal metaphysis, shaft, and distal metaphysis of the tibia, and how it determines the safe pin and wire pathways when fixating the tibia using Ilizarov fixators are described. Wire placement in the foot is described for bridging frame applications for pilon fractures. The safe wire positions adjacent to the knee and ankle joint are described. The lateral centered view is used to safely place wires adjacent to the joint capsule. Unsafe wire and pin positions are illustrated and techniques to avoid poor wire placement are described.

摘要:

SummaryThe biomechanics of tensioned wires and half pins are described. The effects of wire position, number, and configuration on constructing a stiff periarticular fixation block are illustrated. Half pin application to the shaft and construction of a stable base for fixation of periarticular fractures are illustrated. The selection of appropriate ring diameter is based on soft tissue clearance and frame stiffness.

摘要:

SummaryThe fixation blocks used in Ilizarov fixators are illustrated: single ring, ring and 5/8 ring, periarticular double ring block, shaft double ring block, transport ring, and foot frame. Working length mechanisms are illustrated: distraction, compression, rotation, angular correction, translation, and neutralization. Working length rod selection used in fracture treatment is illustrated. Universal hinge mechanisms are discussed.

摘要:

SummaryThe techniques to reduce and fixate OTA Type A, C1, C2, and C3 fractures are illustrated. Fractures with an intact or reconstructible metaphysis are fixated with nonbridging frames (Type A, C1, C2). C3 fractures with joint comminution are treated with bridging extension across the knee joint. Techniques to reduce the joint surface are illustrated. Early resuscitation of the injured patient with emphasis on compartment syndrome and vascular injury is described. The technique for applying half pin anterior resuscitation fixators is illustrated.
