Introduction
Today many radiographers are trained to report on trauma radiographs. Universities are also training student radiographers to comment on trauma radiographs. It is useful, in some cases essential, that whilst we review the trauma radiograph we also recognise and note any appropriate pathology. For instance a patient attends Accident and Emergency (A&E) with pain in their knee for several weeks following trauma; the radiographs show no fracture but some signs of a malignant bony tumour, which on further investigation is an osteosarcoma. It is imperative that the trauma reporting Radiographer Practitioner recognises these signs and seeks advice to allow correct management of the patient. Also some Radiographer Practitioners are expanding their reporting roles into reporting GP patients, myeloma skeletal surveys, bone scans etc. Other professions, such as extended role nurses and physiotherapists, may be reviewing radiographs in clinic and looking at other pathologies, for example, arthropathies or metabolic diseases.
This book, like others in the series, is intended to accompany a reporting course and to be used alongside further research and reading. This book is relevant to all the above professions, but also to any profession that routinely reviews radiographs and has an interest in musculoskeletal pathology. For the more we educate ourselves in our varied professions, the better; not only does it make our job more interesting, provide essential continued professional development (CPD), but also improves the quality of care we provide for our patients.
As with the other books in the series, this book starts with several chapters by different authors followed by a series of cases. The first chapter gives some key points on reviewing some of the many arthropathies. The second is written by Paul Atkinson, an experienced Advanced Reporting Radiographer within the Leeds Trust and a teaching colleague of mine for many years. He discusses the pathogenesis of osteoporosis and the reporting of DXA scans. DXA scans are reported by Radiographer Practitioners at Wharfedale General Hospital.
Next Katy Johnson, a Reporting Radiographer working at Leeds General Infirmary, contributes some helpful pointers for reviewing tumours. There is then a chapter outlining avascular necrosis and the osteochondroses.
Following these chapters are 100 cases. I have tried to find as many different pathologies as possible, so there is a wide range which would under normal circumstances take several years in practice to come across. As with the previous books each case has been anonymised, which may have resulted in side markers being removed. Each case will have some appropriate clinical history or details with it but it may not be the original. For each case you will be asked to write a comment/report which may be descriptive in nature but also may include a diagnosis or a list of differentials. Sometimes additional questions maybe asked. The book is intended to resemble sitting in on a reporting/ teaching session with a Radiologist or Reporting Radiographer.
The cases are divided into 25 arthropathies, 25 tumours, 15 metabolic disease processes, 15 miscellaneous cases which do not quite fit into any other of the categories, and finally 20 mixed cases.
At the end of the book is a reading list and bibliography. Musculoskeletal pathology is a difficult and challenging subject; there is always lots more to learn. I hope you find this book useful and that it helps you to recognise some of the pathologies you may encounter when you are reporting, and also when to ask for another opinion or help!
1 Arthritis
Karen Sakthivel-Wainford
Introduction
Arthritis is a collection of diseases that affect the true or diarthrodial joint (see Figure 1.1). A diarthrodial joint consists of cartilage covering the articular ends of the bones forming the joints, the articular capsule which is reinforced by ligamentous structures and the joint space which is lined with synovial membrane and filled with synovial fluid.

Figure 1.1 Diarthrodial joint
The abnormality of the joint in arthritis usually consists of destruction of the articular cartilage which appears on the radiograph as a narrowing of the joint space; narrowing of the joint is the cardinal sign of arthritis. However in some arthritic processes the joint space may become expanded instead, for example in the early stages of some arthrides, when there is joint effusion and ligament laxity.
However this does not help in distinguishing one arthropathy from another radiographically. The rest of this ch
