Hand and pelvis x-rays (a, b) showed increased light transmittance, narrowing of the joint space, hyperostosis and sclerosis of the subarticular surface, and bony enlargement. Bilateral femoral neck shortening, discontinuous calve line. The left femur (c, d) was fixed in place, the bone structure of the lower femur was disordered, and callus formed. Cervical and lumbar (e, f) decreased bone mineral density, vertebral bodies were compressed and flattened to varying degrees, marginal osteophytes were formed, and endplates were irregular
