Discussion :
Expert’s opinion: This child has a poor diet in vitamins and minerals and also has wrist widening and lumbar lordosis suggestive of vitamin D deficiency. Vitamin D deficiency can lead to hypotonia, exaggerated lumbar lordosis due to pot belly and muscle weakness in addition to rickets. As a result pelvic muscles also become lax and due to that a child may waddle when walking. Hypotonia and muscle involvement is commonly seen with hypophosphatemia rather than hypocalcemia. In this child, serum calcium was 8.8 mg, dl {Normal = 8.5 to 11 mg, dl}, serum phosphorus was 2.9 mg, dl {Normal = 3 to 7 mg, dl} and alkaline phosphatase was 1820 IV, L. X-Ray wrist showed active rickets. The child was treated with vitamin D and calcium supplements following which the gait improved.
