The routes of contamination of the spine, the sacroiliac joint, and other axial skeletal sites are identical to those of the appendicular skeleton. In the spine, early loss of intervertebral disc space is characteristic of pyogenic infection and is associated with lysis and sclerosis of neighbouring bone. These findings can simulate those of other disorders, such as rheumatoid arthritis, intervertebral (osteo)chondrosis, and conditions complicated by cartilaginous node formation. Sacroiliac joint infection is typically unilateral in distribution, a feature that allows its differentiation from many other articular processes. Additional locations in the axial skeleton are not uncommonly infected in intravenous drug abusers and in patients after trauma, surgery, or diagnostic and therapeutic procedures. The candidate will learn the mechanics of putting together an electronic poster presentation in lecture type format. This will be an official peer-reviewed publication. The publication will be a favorable addition to the candidate's CV. The candidate will be the first author, and I am the second author. A candidate is not limited to completing one project. He/she can do as many as they like! (There are always topics to teach about) The candidate, myself, King's College Hospital Department of Radiology and King's College all benefit from this publication.
