    Abstract:
    White matter lesions (WML) are commonly seen in cerebral MR imaging in normal and demented elderly people or young people suffering from migraine. We present data showing that WML are detected in an unexpectedly high frequency (56.9%) in patients with non-traumatic osteonecrosis of the femoral head compared to age and sex-matched controls. We designated the coexistence of WML and osteonecrosis as white matter lesions in osteonecrosis (WMLeON). We examined the possible association of WMLeON with hyperlipidaemia and other risk factors for WML or osteonecrosis of the femoral head. The frequency of history of corticosteroid treatment was statistically lower in patients with WMLeON (58.6%) compared to those without it (90.1%) (P = 0.03). We found no association of WMLeON with diabetes, stroke, hyperlipidaemia, migraine, smoking, alcohol consumption, hypertension, atrial fibrillation, or systemic lupus erythematosus. Although, the clinical significance of WMLeON is still unknown, this finding supports, at least, the hypothesis that non-traumatic osteonecrosis is indeed a multisystem disorder rather than a disease of human skeleton.
