A guide frame for the Taylor Spatial Frame.

Abstract

The Taylor Spatial Frame (TSF) is a versatile multiplanar external fixator that combines ease of application with computer accuracy to effectively reduce fractures and correct all aspects of deformity in reconstructive orthopaedic surgery. However, postapplication adjustments depend on adequate anteroposterior and lateral radiographic measurements to yield the most accurate output from the program. These radiographs need to be taken in an orthogonal plane to the reference ring. We describe a noninvasive technique using a specifically designed radiolucent frame that can be attached to the TSF to guide the surgeon and radiologist in obtaining lateral and anteroposterior radiographs, with the reference ring perfectly orthogonal in single exposures for each radiographic view. By using this guiding frame, reproducible and consistent x-rays oriented orthogonally to the reference ring at different points in the correction may be achieved, thus eliminating the need for repeat radiographs and radiation exposure for patients, radiologists, and surgeons. In this manner, the mounting parameters and the orientation of the bony deformity will be consistent. This should lead to enhanced accuracy of the TSF correction.
