Fig. 1From: Identification of vitamin D and other bone metabolism parameters as risk factors for primary bone marrow oedema syndromeAge distribution of the 65 patients with primary bone marrow oedema syndrome (BMES) and localisation of the 98 lesions. a Frequency of patients in specific age brackets. b Anatomical location of the lesions. The data are shown as number (%). c–e Magnetic resonance imaging (MRI) scans of BMES lesions in the knee, distal tibia and tarsal bones. The scans show the distinctive MRI patterns.
