Femur Deformity Correction With 3D Printed Patient-Specific Instruments
3D pre-surgical planning and the use of Patient-Specific Instruments in a Femur deformity correction surgery.

Femur Deformity Correction with 3D Printed patient-specific instruments: News
The patient is a 16-year-old male.
The purpose of the surgery was to correct the femur deformity.
In the first step, a 3D segmentation was made from CT data. The healthy contralateral side was mirrored, precisely aligned and used as a template for the correction. the osteotomies were planed to match the template. The surgeons decided to reconstruct with two osteotomies for a close wedge.

A 3D printed model with the final position of the bone was made to match the fixation plates. Drilling and cutting guides were designed according to the positioning of the plates screws.

With the help of these guides, the surgeons pre-drills the screw holes before the osteotomies are preformed and the saw blade is guided through slots built into the cutting guides. To achieve the planned correction, the plate was placed on the bone by aligning the pre-drilling holes. Thanks to the experienced surgeons and the accurate PSI, the result was exactly like the plan.
