Provided is a bone inspecting system for placing the lower legs (L) of an examinee (P) on a proximal support block (26) and a distal support block (28) mounted on a turning base (24). The proximal support block supports the heads of fibula, and the distal support block supports the lateral malleolus or medial malleolus of a tibial distal end of the examinee. The turning base is supported turnably on a turning axis positioned near the knees of the examinee, with respect to a main base (22), and is moved up and down by an elevating mechanism (30) disposed near the ankles. The turning base (24) is turned by the elevating mechanism while bearing the lower legs thereon, thereby positioning the lower legs horizontally.
