• Gaucher Disease

  The osteonecrosis was idiopathic in 6 shoulders, was a result of corticotherapy in 10, occurred after radiation in 2, and occurred after Gaucher's disease in 1. A total shoulder arthroplasty was performed in 5 cases and a hemiarthroplasty in 14. [ncbi.nlm.nih.gov]

• Soft Tissue Mass

  An associated soft tissue mass is unusual with osteonecrosis; the presence of a soft tissue component suggests tumor recurrence. Radiation necrosis of the skull usually occurs after a minimum radiation dose of 3500 cGy. [emedicine.medscape.com]

• Bone Disorder

  Unlike other bone disorders, this happens most often in men between age 40 and 50. Untreated injuries and diseases can cause AVN. Other causes include: Injury, such as a major impact from an accident or during sports. [upmc.com]

The purpose of this article is to report a prototypical case with complete radiographic and histologic workup and to provide facts regarding Kummel disease that are salient to the primary care provider. [doi.org]

Besides confirming the diagnosis, another major role for the radiologist in the workup of osteonecrosis is staging the current state of the disease. The usual plain film and MR stages are listed below. [rad.washington.edu]

MI), admission is indicated to a unit with telemetry monitoring and transcutaneous pacing capabilities Symptomatic patients should be treated with atropine and transcutaneous pacing immediately, followed by transvenous temporary pacing until further workup [emedicine.medscape.com]

This should be managed like a type II with transcutaneous or transvenous pacing until further workup can be completed. [ncbi.nlm.nih.gov]

Early diagnosis and treatment of this entity are crucial because it affects relatively young individuals, and treatment options for advanced disease are limited. [doi.org]

Therefore, early treatment to slow or prevent progression and save the joint is desirable. No completely effective treatment is yet available. [merck.com]

Most people with osteonecrosis need treatment. The goals of treatments are to: Improve use of the joint. Stop further damage. Protect bones and joints. Your treatment options may include surgery or nonsurgical treatments, such as medicines. [niams.nih.gov]

In addition, lesion size and location can be more easily assessed on magnetic resonance images, and this has been shown to relate to prognosis and need for treatment. [doi.org]

Clinical data as well as treatment and prognosis information were obtained from all 14 patients. RESULTS: Twelve patients (86%) were submitted to biphosphonate therapy. [ncbi.nlm.nih.gov]

They have been used most often in treating osteonecrosis of the hip where the prognosis without treatment is worse than that for other regions. [merck.com]

The best way to prevent AVN is to maintain strength and flexibility. Be sure to warm up before any physical activity and include strength training in your workouts. [upmc.com]

Recognition of the quite characteristic imaging findings can prevent misdiagnosis and may have implications for the prediction of the natural course of the disease. [ncbi.nlm.nih.gov]
