Regarding osteoporosis, all of the following statements are true except: March 2012: (A) Raised alkaline phosphatase, (B) DEXA scan is helpful, (C) Reduced bony matrix, (D) Cod fish appearance on X-ray
Answer is A. Ans: A i.e. Raised alkaline phosphatase Osteoporosis Serum calcium, phosphates & alkaline phosphatase are within normal limits. DEXA scan is an X-ray based bone densitometry, & is the gold standard in the quantification of bone mass Osteoporosis is characterised by a diffuse reduction in the bone density due to a decrease in the bone mass X-ray shows Cod fish appearance (disc bulges into the adjacent veebral bodies so that the disc becomes biconvex)
