Infantile Myofibromatosis of the Femoral Neck: A Case Report

JBJS Case Connect. 2024 Feb 16;14(1). doi: 10.2106/JBJS.CC.23.00478. eCollection 2024 Jan 1.

Abstract

Case: A 15-month-old boy who was being followed for developmental dysplasia of the hip because of breech presentation was discovered to have a solitary infantile myofibroma in the left femoral neck. The patient was avoiding weight-bearing on the affected extremity; thus, stabilization of the femoral neck was performed using a proximal femur locking plate. Postoperatively, he achieved all gross motor developmental milestones.

Conclusion: This report is the first to describe a solitary infantile myofibroma in the femoral neck and demonstrates the utility of operative stabilization of these lesions.
