Precontouring Plates for MIS Bilateral Femur Osteosynthesis Using a Patient-Specific 3D Printed Model: A Case Report.

CASE: A 27-year-old woman with increasing bilateral thigh pain and underlying diagnosis of dysosteosclerosis was diagnosed with bilateral impending pathological femur fractures. Both femurs exhibited abnormal morphology with bowing, thickened cortices, and narrow intramedullary canals. We planned minimally invasive prophylactic plate osteosynthesis. Computed tomography scans of both femora were obtained and used to generate 3-dimensional (3D) printed models. Osteosynthesis plates were precontoured to fit the 3D models and sterilized, and prophylactic fixation was performed using a minimally invasive submuscular technique.

CONCLUSION

3D printed models aided in precontouring fixation plates in a case with challenging bony anatomy, enabling minimally invasive surgery.
