This Module will teach you a basic approach to the radiologic diagnosis of arthritis. By the end of the module, you should be able to confidently recognize the most common appendicular and axial arthropathies.
The approach you learn here should help you correctly diagnose the presence and type of arthritis in about 95% of cases in real life. Learning that remaining 5% will take the rest of your professional career.
- A brief introduction to the world of expansile, lucent lesions of bone.
The bones of the skull and face collectively make up the most complex area of skeletal real estate in the body. Analysis of the fractured face requires a knowledge of not only normal anatomy, but also of common fracture patterns in the face.
This module describes the role of the radiologist in the interpretation of post-operative orthopaedic images, many of which contain metallic devices. Indications for internal and external fixation are described, and numerous examples of these devices are shown.
Osteonecrosis bespeaks bone death. Synonyms include aseptic necrosis, bone necrosis, avascular necrosis, bone infarction and ischemic necrosis. This module will introduce one to causes of osteonecrosis, its pathophysiology, and imaging features.
One of the most common findings in skeletal radiology is increased radiolucency of bone, most properly termed osteopenia. This term is much preferred over terms such as "demineralization" or "undermineralization", since we really can't tell the exact mineral status of the patient's bone from the radiograph alone. The most common cause by far of osteopenia is osteoporosis. This, and other disease entities that can cause osteopenia will be discussed here.
Fractures which disrupt the pelvic ring are a common and often life threatening result of major trauma. They are associated with serious orthopedic management problems in the pelvis as well as fractures and soft tissue injuries in other sites. Pelvic trauma is further complicated by non-orthopedic injuries to the GU tract, visceral organs, chest, central nervous and vascular systems.
The acetabulum is a portion of the pelvis that is often fractured during trauma to the pelvis, either as part of a pelvic fracture or in isolation. Acetabular fractures are usually complex and result in articular incongruity, leading to postraumatic osteoarthritis. Classification of acetabular fractures is important so that the orthopaedist can plan appropriate treatement strategy.
The radiologist needs to be familiar with the emergent evaluation of patients with pelvic and acetabular fractures: to guide imaging choices, to expedite prompt and accurate patient diagnosis, and to effectively communicate with the referring trauma surgeons.
Joint prostheses have an important role in the treatment of arthritis and other joint diseases. This module will discuss the normal appearance of a variety of prostheses. Prostheses can loosen over time, or fail for other reasons. The radiographic appearance of these complications will also be revealed.
