Patient's question:
Recently, I've been walking with an inward turning gait. I went to the hospital, and after the doctor examined my calf, they said it's a case of O-shaped legs. They took a blood test for bone alkaline phosphatase, and the result was 200-225 (reference range: <200). The 25-hydroxyvitamin D test result was 25.59 (reference range: 35-150). I'd like to ask what these results mean? The clinical diagnosis written above says rickets, so is it due to calcium deficiency or vitamin D deficiency?Doctor's answer:
According to your report, the child's O is likely a sequelae of rickets. However, the BALp200 you checked is considered normal, but the 25-hydroxy 25.9 is low, indicating a deficiency in vitamin D, which suggests the condition is in remission. Therefore, it can also be referred to as rickets. A deficiency in vitamin D can lead to a lack of calcium, as vitamin D helps in the calcification process. The common term for this among the general public is "low calcium." We recommend correcting the vitamin D to normal levels, after which the O can be corrected through insole padding or longitudinal arch supports.
