When Bones Tell a Story: Diaphyseal Femoral Fracture in a Child With Pycnodysostosis.

Pycnodysostosis (PYCD) is a rare genetic disorder marked by generalized bone sclerosis and a high risk of fractures. On average, children with PYCD experience approximately 0.2 fractures per year, often complicated by delayed healing and poor bone remodeling. Surgical treatment of long bone fractures in patients with PYCD is scarcely documented in the literature, and orthopedic surgeons play a crucial role in managing the affected children. In this article, we present the case of an 11-year-old boy diagnosed with PYCD who presented to the pediatric surgery department for the management of a femoral diaphysis fracture, and we discuss the therapeutic difficulties.
