Question

primary hyperparathyroidism in the advanced stage produces: osteogenesis imperfecta osteitis deformans osteitis fibrosa cystica renal osteodystrophy osteomalacia

Explanation:

Primary hyperparathyroidism in the advanced stage causes excessive bone - resorbing activity. Osteitis fibrosa cystica is a characteristic bone lesion associated with long - standing primary hyperparathyroidism due to increased parathyroid hormone levels leading to bone breakdown. Osteogenesis Imperfecta is a genetic disorder related to collagen synthesis. Osteitis Deformans (Paget's disease) has different etiologies not directly related to hyperparathyroidism. Renal osteodystrophy is related to kidney disease - induced bone changes. Osteomalacia is mainly due to vitamin D deficiency or problems in vitamin D metabolism.

Answer:

Osteitis fibrosa cystica
