Surgical Technique: Achieving Reduction With Temporizing, Knee-Spanning External Fixation.

Abstract

Peri- and intra-articular fractures about the knee are frequently managed with joint-spanning external fixation before definitive treatment. With a systematic approach, a near-anatomic reduction with respect to length, alignment, and rotation can be obtained. This video highlights 2 clinical cases: a bicondylar tibial plateau fracture-dislocation and a distal femur fracture, both of which were treated with temporizing, knee-spanning external fixation. The indications, principles, and biomechanics of knee-spanning external fixation are presented. In addition, we demonstrate a systematic approach to applying knee-spanning external fixation. Temporizing, joint-spanning external fixation is a critical treatment modality in the orthopaedic armamentarium for managing fractures about the knee. With a systematic approach, it is possible to obtain a near-anatomic reduction with respect to length, alignment, and rotation.
