Bilateral Nonunion of Femoral Neck Fractures Because of Nutritional Osteomalacia

Abstract

Case: We report 2 cases of atraumatic, bilateral femoral neck fracture nonunions. Both the patients were relatively young and had underlying nutritional osteomalacia. In both cases, valgus intertrochanteric osteotomy was performed along with vitamin D and calcium supplementation. The patients were followed up for an average of 3 years and achieved bone union without any complications. Conclusion: Bilateral femoral neck fractures are rare, and bilateral nonunion of femoral neck fractures secondary to osteomalacia is even rarer. Valgus intertrochanteric osteotomy can salvage the hip. Correction of underlying osteomalacia by vitamin D and calcium supplementation preceeded surgical intervention in our cases.

Non-traumatic Simultaneous Bilateral Femur Neck Fracture in a Young Female Unraveling End-Stage Renal Disease: A Case Report and Literature Review

“…An example is provided in the case report by Annan and Buxton, where the abnormal length and more varus position of the femoral neck placed additional stress on it [ 12 ]. Multiple papers have reported bilateral neck of femur fractures secondary to altered bone metabolism, whether due to osteoporosis [ 10 ], Vitamin D deficiency [ 11 ], or as a part of renal osteodystrophy [ 5 , 13 - 18 ].…”
