Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. [1] Early on, there may be no symptoms. [ 1 ] Gradually joint pain may develop, which may limit the person's ability to move. [ 1 ]
Short-term side effects of prednisone are uncommon but can include mood changes, avascular necrosis, and an increased risk of infection. [31] Some of the side effects associated with long-term use include weight gain, diabetes mellitus, osteoporosis, avascular necrosis, glaucoma, cataracts, cardiovascular disease, and an increased risk of ...
Soft tissue injuries can be evident when bruises are present. Muscle or ligament injuries can be contracted during heavy physical activity —however, it is important not to miss a slipped upper femoral epiphysis. Avascular necrosis of the femoral head (Legg-Calvé-Perthes disease) typically occurs in children aged 4–8, and is also more ...
Particular medications can result in MRONJ, a serious but uncommon side effect in certain individuals. Such medications are frequently used to treat diseases that cause bone resorption such as osteoporosis, or to treat cancer. The main groups of drugs involved are anti-resorptive drugs, and anti-angiogenic drugs.
MR can demonstrate abnormalities in these cases, such as increased joint volume or a ligamentum teres tear (Figure 9). [1] Intra-articular osseous causes of pain include several conditions: avascular necrosis (AVN), transient osteoporosis of the hip (TOH), tumors, and stress or insufficiency fractures.
Prednisone is a glucocorticoid medication mostly used to suppress the immune system and decrease inflammation in conditions such as asthma, COPD, and rheumatologic diseases. [3] It is also used to treat high blood calcium due to cancer and adrenal insufficiency along with other steroids . [ 3 ]
Preiser disease, or avascular necrosis of the scaphoid, is a rare condition where ischemia and necrosis of the scaphoid bone occurs without previous fracture.It is thought to be caused by repetitive microtrauma or side effects of drugs (e.g., steroids or chemotherapy) in conjunction with existing defective vascular supply to the proximal pole of the scaphoid.
The International Osteoporosis Foundation and the European Calcified Tissue Society recommend pharmacological therapy for osteoporosis in postmenopausal women and men ≥70 years, with a previous fragility fracture, or a dose equivalent of prednisone ≥7.5 mg daily for ≥3 months. For premenopausal women and men <50 years taking steroids for ...
