The correct answer is AOsteomalacia in the adult is the analogue of rickets in the child. It results from calcium and phosphorus deficiency in the bone.
Almost all forms of osteomalacia are associated with compensatory, secondary hyperparathyroidism, set off by low calcium level. The most frequent complaints are diffuse skeletal pain, proximal muscle weakness, bone tenderness, and hypotonia with preservation of brisk reflexes.
Lab: slight hypocalcemia, hypophosphatemia, elevated ALP, low-normal urinary calcium excretion, elevated level of PTH. Serum levels of 25-OH-D are often depressed.
X-ray: diffuse osteopenia; the only specific finding is the
pseudofracture (Looser's zone).
