The Displacement Osteotomy as a Correction Principle

Abstract

The principle of the displacement osteotomy offers a valuable alternative to the classic closed wedge osteotomy and effectively augments our capabilities for the surgical treatment of posttraumatic deformities. With the displacement osteotomy it is possible to align the fragments with the mechanical axis of the joints while simultaneously correcting angular deformity. This restores a physiologic weight-bearing alignment and transforms bending forces into compressive forces, which are favorable for bone consolidation. The displacement osteotomy does not require the resection of a bone wedge, and axial correction is effected by aligning and then impacting the osteotomy fragments. This produces a good primary stability and provides a secure foundation for internal fixation. The osteotomy can also be used to lengthen an entire bone or a portion of it, such as the femoral neck in a double intertrochanteric osteotomy.
