Tension-Sided Femoral Neck Stress Fracture in an Adolescent with Vitamin D Deficiency and Osteomalacia: A Case Report.

Case An adolescent girl presented with groin pain without any history of trauma. Imaging showed a tension-sided stress fracture of the femoral neck. Vitamin D deficiency (VDD), and raised alkaline phosphatase and parathyroid hormone levels were found. Pain relief was not achieved with nonoperative treatment. Considering the risk of fracture progression and displacement, the fracture was fixed with cannulated cancellous screws. Fracture healed without any complications. Conclusion A tension-sided femoral neck stress fracture, with VDD and osteomalacia, is a rare cause of hip pain in an adolescent. Surgical fracture stabilization is necessary in addition to medical treatment.
