Fig. 4From: Characterization of nano-structural and nano-mechanical properties of osteoarthritic subchondral boneHR-TEM and SAED correlated with EDS spectrum images of freshly extracted minerals from grade I (a, c, e) and grade IV OA sourced trabecular bone (b, d, f). (a, b) Nano-particles of minerals extracted from (a) grade I and (b) grade IV OA trabeculae. (c, d) SAED pattern of mineral particles from (d) grade IV OA trabeculae exhibited higher intensity diffraction rings than the (c) grade I OA trabeculae. (e, f) EDS spectra for the nano-mineral particles from the (e) grade I and the (f) grade IV OA trabeculae. The images are representative of 5 different patient samples graded according to the disease severityBack to article page
