• Conditions: Pathologic Fracture

• Registration Number: NCT06800417
• Lead Sponsor: Innoprod Medical

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Rate of patients which have a pain reduction rate, at 6 weeks postoperatively, equal or superior to 30%	From the patient inclusion date to 6 weeks postoperatively	Pain reduction is measured with the VAS scale : Zero is equivalent to no pain and 10 indicates the worst possible pain

Secondary Outcome Measures

Name	Time	Method
Implantation success rate of the InnoFix® screw	At the end of surgery	Implantation succes is measured with medical imaging: Screw position compared to the fracture line and distance, in millimeters, of the distal tip of screw compared to the planned area and protrusion, in millimeters, of the proximal part of screw from the external cortex
Rate of InnoFix® screws with their integrity preserved postoperatively	From end surgery to 6 weeks and 6 months postoperatively	Screw integrity is measured with medical imaging: Disassembly, breakage or bending in millimeters
Satisfaction rate of the radiologist regarding the efficiency of the percutaneous implementation	At the end of surgery	Efficiency of percutaneous implementation is based on the experiency of the radaiologist
Satisfaction rate of the radiologist regarding the efficiency of the percutaneous cementing	At the end of surgery	Efficiency of percutaneous cementing is based on the experiency of the radaiologist
Rate of stable InnoFix® screws postoperatively	From end surgery to 6 weeks and 6 months postoperatively	Screw stability is measured with medical imaging: Screw displacement in millimeters and contact with anatomical structures or other implanted devices
Rate of patients which have a pain reduction rate, at 6 months postoperatively, equal or superior to 30%	From the patient inclusion date to 6 months postoperatively	The pain is measured with the VAS scale: Zero is equivalent to no pain and 10 indicates the worst possible pain
Rate of patient which have had, at least, one adverse event in relation with the InnoFix® screw postoperatively	From the patient inclusion date to 6 months postoperatively	Adverse event reported
Rate of patient which have had, at least, one serious adverse event in relation with the InnoFix® screw postoperatively	From the patient inclusion date to 6 months postoperatively	Serious adverse event reported
Rate of postoperative stable fractures	From end surgery to 6 weeks and 6 months postoperatively	Fracture stability is assessed with medical imaging: Length of fracture line in millieter (complete fracture) or fracture occurernce (impending fracture)
Rate of patients which have a mobility improvement rate postoperatively	From the patient inclusion date to 6 weeks and 6 months postoperatively	Mobility is measured with ECOG scale:
