#Xray hip normal vs abnormal how to

For instance, fluid in your lungs can be a result of congestive heart failure. Chest X-rays can show changes or problems in your lungs that stem from heart problems. They can also show chronic lung conditions, such as emphysema or cystic fibrosis, as well as complications related to these conditions. Chest X-rays can detect cancer, infection or air collecting in the space around a lung, which can cause the lung to collapse. A chest X-ray can also be used to check how you are responding to treatment.Ī chest X-ray can reveal many things inside your body, including: A chest X-ray is often among the first procedures you'll have if your doctor suspects heart or lung disease.

The condition tends to occur between 1 and 5 years after surgery and is associated with smooth endosteal scalloping.Chest X-rays are a common type of exam. Radiographically these aggressive granulomatous lesions present as focal radiolucencies around the prosthesis. Nowadays it is mostly seen in non-cemented hips as a reaction to small polyethylene wear particles. It is a histiocytic response that occurs as a result of macrophage reaction to any of the components, that are shed of the surface of the components of the arthroplasty. Originally this was called cement disease or aggressive granulomatosus. You have to be familiar with the normal and abnormal changes in the types of prostheses, that are used by your orthopaedic surgeons. The figure on the left sums all the findings in some of the non-cemented prostheses, that can be normal.

This fibrous tissue presents as a lucent zone at the interface.Īgain it should be stable and well within a range of 1 -2 mm.

In stable non-cemented hip arthroplasties lucent zones at the metal-bone interface do occur, as it usually is a combination of bone ingrowth and fibrous tissue ingrowth, that provides the fixation in most cases. The distal part of the femoral prosthesis is not 'loaded', so there will be no distal stress loading. In an effort to avoid these changes, most modern cementless prosthesis only have fixation proximally, so you usually will not find proximal stress shielding. Stress loading distally may result in cortical thickening and bridging sclerosis at the tip of the prosthesis ( called pedestal). Stress shielding proximally may result in proximal osteoporosis and calcar resorption. The implantation of a bone ingrowth prosthesis results in altered stress distribution to the native bone, especially in the older models with non tapered and fully coated femoral stems. Rare complications include bowel fistulas, encasement of neurovascular structures and bladder wall burn. This defect is filled with bone chips, cement or bone transplant.Ĭement extrusion is usually asymptomatic. When the acetabulum is prepared for placement of the cup a perforation may occur. Most intraoperative fractures occur on the femoral side. The incidence of fractures ranges from 0.1 to 1.0 percent for cemented components and 3 to 18 percent for uncemented components. They are also more common in non-cemented femoral stems, as these have to fit exactly and can cause a fracture during insertion. When the anatomy is abnormal as in hip dysplasia.
