Ulnar Nerve Decompression and Transposition - Medical Illustration, Human Anatomy Drawing
This stock medical exhibit depicts ulnar decompression and transposition. The first illustration shows the pre-operative condition of the elbow, in which severe left ulnar neuropathy and elbow contracture freeze the elbow joint in 90 degree flexion. The second illustration shows swelling and scarring of the ulnar nerve at the cubital tunnel. The third illustration shows the first step of the procedure, in which an incision is made in the medial aspect of the left elbow to access the underlying ulnar nerve. The fourth illustration shows the decompression of the nerve and the division of the overlying flexor tendons. The fifth illustration shows the reapproximation of the soft tissues so that the nerve can lie on a smooth layer of soft tissue and glide during motion of the elbow.
