ABSTRACT
Abstract Background The goal of stabilization the femoral neck is to limit morbidity and mortality from fracture. Of three potential methods fixation, (three percutaneous screws, Synthes Femoral Neck System, a dynamic hip screw), each requires guide wire positioning implant(s) in head. Consistent accurate these systems paramount reduce surgical times, stabilize fractures effectively, complications. To help expedite surgery achieve ideal implant geriatric population, we have developed validated planning methodology using 3D modelling printing technology. Methods Using image processing software, models were generated placing wires virtual model an osteoporotic proximal femur sawbone. Three unique drill guides created optimal position for placement different systems, printed. Subsequently, trauma fellowship trained orthopedic surgeon used printed 2.8 mm diameter bit tipped into five sawbones (fifteen total). Computed Tomography (CT) scans then taken with implants place. renderings CT techniques displacement angular deviations at entry sawbone measured. Results Across all screw wires, average was 3.19 ± 0.12 deviation 4.10 0.17 o . System had 1.59 0.18 2.81 0.64 Dynamic Hip Screw 1.03 0.19 2.59 0.39 Conclusion use custom assist proved be types strategies. Guides which are place more than 1 may lower positional accuracy, as shift during multiple insertions. We believe that personalized point care provide intraoperative method neck.
