Epidemiological Study of Femoral Head Osteonecrosis

Abstract

In recent years, there has been an increase in the number of studies on the etiology of femoral head necrosis. We retrospectively reviewed all patients diagnosed with aseptic necrosis of the femoral in the period of 2010-2015. We recorded a total of 230 cases diagnosed with aseptic necrosis of the femoral head, group was composed of 65.7% men and 34.3% women, risk factors identified was 19.13% (post-traumatic), 13.91% (glucocorticoids), 26.52% (alcohol), 3.47% (another cause) and in 36 95% of the cases no risk factors were found. The results of the study based on the type of surgery performed on the basis of stages of disease progression, 8 patients (3.48%) benefited from osteotomy, 28 patients (12.17%) benefited of bipolar hemiarthroplasty prosthesis and 188 patients (81.74%) benefited of total hip arthroplasty. Osteonecrosis of the femoral head is characteristic to young patients between the age of 30-50 years old. Predisposing factors, alcohol and corticosteroid therapy remains an important cause of the disease. Total hip arthroplasty remains the best option for the patients with osteonecrosis of the femoral head.

Etiology of femoral head avascular necrosis in patients: A cross-sectional study

“…Numerous studies have been conducted in recent years to investigate the etiology of AVN, in which a review study that has examined several studies has identified steroid and alcohol use as the most important risk factors. [ 16 ] Studies have also reported the use of corticosteroids as the main risk factor for AVN. In a study conducted at Rasoul Akram Hospital in Tehran, Iran, in 2013–2015, 42% of patients with AVN were treated with corticosteroids, 4% with bisphosphonates, and 4% with hematologic disease.…”
