Management of long bone fractures in patients with pycnodysostosis.

Pycnodysostosis is a rare genetic condition that leads to generalised bony sclerosis and increased fracture risk. Orthopaedic specialists play a crucial role in managing affected children due to their susceptibility to frequent fractures. We had a case of a middle childhood female patient with pycnodysostosis and a femur fracture. Initially, an attempt using the Titanium Elastic Nailing System was made, but the sclerotic metaphyseal bone made it challenging. So, we opted for a 4.5 mm locked compressive plate, with multiple drill bits as a backup due to potential drill breakage. Though elastic nailing is preferred for paediatric long bone fractures, surgeons must be prepared for extremely sclerotic cortices and a narrow medullary canal when dealing with patients with pycnodysostosis. Open fixation and multiple drill bits in the toolkit are essential to overcome the potential obstacles during the procedure.
