Orthopaedic human skeletal demonstration aids

Abstract

An orthopaedic human skeletal demonstration aid for demonstrating surgical orthopaedic techniques consists of a facsimile of at least part of a human vertebral column including a plurality of vertebral elements simulating the external appearance of human vertebrae, and a plurality of intervertebral disk elements disposed intermediate the vertebral elements. The vertebral elements and the intervertebral disk elements are provided with central apertures and are releasably secured together by an externally screwthreaded flexible rod extending through apertures and provided with nuts at its ends for securely clamping the elements together. Such an aid is capable of being flexed to simulate anatomical distortions of the human spine, and can be used for demonstrating a wide range of replacement or repair techniques, including fitting of a surgical implant.
