Arthroscopic correction for concomitant cam impingement in a patient with idiopathic osteonecrosis of the femoral head: A case report

Abstract

HighlightsIt is important to accurately diagnose the status of idiopathic osteonecrosis of the femoral head and to consider another possible pathogenesis when a patient with idiopathic osteonecrosis of the femoral head has hip pain even without femoral-head collapse.Ignored or misdiagnosed concomitant femoroacetabular impingement in a patient with idiopathic osteonecrosis of the femoral head might leads to poor outcomes of surgical treatments such as bipolar hemiarthroplasty or osteotomies.In a patient with idiopathic osteonecrosis of the femoral head, it should be paid attention if concomitant femoroacetabular impingement exists or not.

Association of Genes Variants in RANKL/RANK/OPG Signaling Pathway with the Development of Osteonecrosis of the Femoral Head in Chinese Population

“…In addition, our results also confirmed the association of OPGrs2073617 genotypes with the etiological classification of ONFH. Idiopathic ONFH often occurs in young and middle-aged patients, and most of the radiographically larger lesions progress to collapse, resulting in the rapid destruction of the hip joint 18 . Excess corticosteroid and alcohol abuse have been identified as environmental risk factors for the development of steroid- or alcohol-induced ONFH, respectively 19 , but the risk factors of idiopathic ONFH has been remained unclear.…”
