Common symptoms of rickets in adults include the following: First, bending of the lower limbs occurs. The obstruction of mineral salts in the bone during deposition in patients with rickets can cause bending of the long bones of the lower limbs, which is manifested as inversion of the knee joint or knee exostosis, with the appearance of O-leg or X-leg. Second, pain in the bone at the site of the lesion, as well as muscle weakness, has a correlation with reduced calcium ion concentration in the blood and osteoporosis. Thirdly, pathological fracture. When rickets occurs, the whole body bone volume is drastically reduced and bone strength is decreased, and pathological fracture can occur even with slight external force. Adult rickets lesions are mainly concentrated in the bone, with bone softening as the main manifestation, while there are significant differences in the clinical manifestations of different individuals.
