Lab Studies:
Initial evaluation found severely low vitamin D (25-OH) and phosphate levels. Calcium was within normal limits. His parathyroid hormone and alkaline phosphatase were found to be elevated.
Serial testing revealed persistently low phosphate and vitamin D (25-OH) despite repletion. Laboratory results are demonstrated below Case Photo #4 .
Other Studies:
Bilateral hip and pelvis x-rays demonstrated cortical thickening with compression-sided linear lucencies in the bilateral femoral necks compatible with chronic stress fractures. This was unchanged from prior imaging in 2015.
Case Photo #1
Lumbosacral spine x-rays were negative. A pelvis MRI without contrast was consistent with prior x-rays, demonstrating chronic incomplete fractures spanning less than 50% of the femoral neck. It also revealed mild coxa vara bilaterally.
Case Photo #2
Subsequent x-rays at 10 months and one year after the most recent ED presentation demonstrated no significant interval healing. Imaging showed neck-shaft angles with less than 120 degrees, being diagnostic for coxa vara.
Case Photo #3
Consultations:
At his most recent presentation to the ED, orthopedic surgery was consulted and no surgical intervention was recommended.
