The purpose of this study is to determine if prolonged administration of low-dose aspirin will prevent the progression of early-stage osteonecrosis of the femoral head and may even reduce the extent of involvement of the femoral head by the necrotic process The design is intended to be parallel group where a total of 114 patients will be randomized in a 1:1 ratio to the treatment (ASA) and the control (Placebo) arms.
TRIAL OBJECTIVES The primary objective of this study is to evaluate the radiologic progression of ONFH on either radiographs or MRI. A successful outcome is defined as no difference in ONFH staging according to the Ficat \& Arlet or Steinberg classifications at last patient follow-up compared to initial radiological staging. This translates into lack of progression over the course of the study while the natural evolution is progression over time.
The secondary objective is to evaluate the percentage of involvement of the femoral head on radiographs and/or MRI which measures the extent of the disease. We expect that the extent of the disease will be reduced at 2 years.
All patients presenting to the osteonecrosis clinic of one of the participating centres will be first evaluated by an orthopedic surgeon to confirm the diagnosis of early ONFH on at least one hip. Selected patients will be screened for eligibility according to specific inclusion and exclusion criteria.
Eligible patients who accept to participate in this study will be randomized to either a control arm (placebo) or a treatment arm (Aspirin). Recruited patient will take their assigned treatment daily at breakfast from enrolment and for a minimum of two years They will be followed over a period of 2 years. Evaluations will be taken at baseline and every 6 months (5 visits in total).

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
