The purpose of this clinical investigation is to collect data about the safety and the performances of the InnoFix® screw : Clinical performances (Pain reduction due to the fracture treatment, maintenance of the stabilizaton of the treated fracture and mobility improvement) / Technical performances (Percutaneous implantation by mini-invasive approach, Efficiency of percutaneous implementation and efficiency of percuatneous cementing) / Safety performances (Preservation of the screw stability after implantation and preservation of the screw integrity after implantation). The safety and performance data about the InnoFix® screw will be used to obtain their CE marking according to the regulation (EU) 2017/745.

The principal objective of this clinical investigation is to assess the postoperative reduction in pain level of the patient at 6 weeks follow-up.
