PINILLA-GRACIA, C et al. Epidemiology, clinical results and success rate in hip preservation surgery in avascular osteonecrosis of the femoral head. Acta ortop. mex [online]. 2020, vol.34, n.1, pp.16-21.  Epub 27-Sep-2021. ISSN 2306-4102.


Avascular osteonecrosis of the femoral head (ONFH) is a frequent pathology with an insidious and asymptomatic presentation in early stages, so the diagnosis is often made in advanced stages, where the only effective solution is total hip arthroplasty (THA). Diagnosis in early stages will allow the use of therapeutic options that avoid or delay ATC. Our objective is to evaluate the demographic, clinical results and the success rate in our center of patients diagnosed with ONFH and who have been subsidiary of hip preservation surgery.

Material and methods:

Unicentric, prospective, uncontrolled clinical study of patients diagnosed with ONFH between January 2012 and September 2017 with a Steinberg ≤ IIIA stage. The surgical technique used is decompressive forage, associated with bone allograft and bone marrow aspiration.


26 hips were operated on with our surgical technique. The success rate obtained is 61.54%, since 10 cases have required THA during the study (38.46%).


The therapeutic success in ONFH is directly related to the degree of the disease, which is why early diagnosis is important. The decompressive forage with bone allograft that associates bone marrow aspiration is an option to be taken into account, since in early stages it shows a high success rate.
