Prevalence Study of Femoral Head Avascular Necrosis and Evaluating Mutual Connection between Injury and Viral Infections: Clinical Analysis and Brief Review

Avascular necrosis (AVN) could remain with negligible clinical symptoms, but it would get worsen over the time if it’s left untreated and at the most cases will require surgical treatment. Prevalence of femoral head AVN is almost 0.45% among HIV patients which is approximately 45 times more than the rest of Society. AVN occurs 0.088%-1.33% annually among HIV victims. Avascular necrosis of the femoral head is a bone deteriorating plight. At this study, the clinical prevalence of it has been analyzed among a group of 180 patients at Rasool-e-Akram Hospital (Iran, between 2008 and 2016). Patients were including 121 men and 59 women. Analysis results showed that the prevalence of HCV, HBV, and HIV was 1.7%, 1.1%, and 1.1% respectively. It was found that 63% of patients was currently using immunosuppressive drugs. 17% had a history of drug abuse among which 3.3% were using IV drugs. It was concluded that femoral head AVN is more common among hepatitis and HIV patients.
