Study of the Effectiveness of a Polymer Cerclage System Compared to Cerclages Used in Standard Care (CERCPMCF) )

• Implantation of Ortholoop cerclage (Device): implantation of Sterile Self Locking Polymer Cerclage System named OrthoLoop to the patient and follow up for 36 months post-intervention
• Implantation of Cerclage used in current practice (Device): implantation of Cerclage used in current practice to patients and follow up for 36 months post-intervention

Primary outcomes

• Assess role of Polymer Cerclage System OrthoLoop of COUSIN Biotech in comparison with cerclages (metallic for the majority) used in standard care; in the optimization of the consolidation of primary and periprosthetic fractures of long bones [6 months post-surgery]: primary endpoint will be success or failure 6 months after surgery: Success of "Sterile Self Locking Polymer Cerclage System" to optimize consolidation during 6 months post surgery is defined as: * the ability to walk full weight bearing without pain at the fracture site, or return to normal, painless mobility at the fracture site, * and radiographs showing signs of bony union with no rupture or migration of the cerclage. Rupture or cerclage migration or nonunion or need for revision of the implant before 6 months is considered as failure.

Secondary outcomes

• Assess consolidation rate during 6 months post surgery [6 months post-surgery]: Consolidation (or union) is defined as the ability to walk full weight bearing without pain or return to normal, painless mobility at the fracture site , and radiographs showing signs of bony union
• Asses union time [3, 6 and 36 months post-surgery]: Union time is defined as time from intervention until * For Femoral fracture: ability of patient to walk full weight bearing without pain at the fracture site and radiographs showing signs of bony union * For humeral fracture: The patient regained full mobility without pain at the fracture site.
• Assess rupture and migration rate of the cerclage after surgery throughout the follow-up [3, 6 and 36 months post-surgery]: Rupture and migration of the cerclage are confirmed on X Ray imaging.
• Assess pain [6-8 weeks,3, 6 and 36 months post-surgery]: Pain will be assessed using visual analog scale pain scores (VAS) from 0 to 100 (0 means no pain at all and 100 maximum pain) at each visit.
• To report the incidence of complications and their treatment, particularly with respect to the need of further surgery [During the whole study (up to 36 months)]]: Safety data during patients 36 months follow up are defined such as: Infection Neurovascular injury Allergic reaction Bone ischemia Irritation feeling
• Assess surgery characteristics [During surgery (at D0)]: Surgery characteristics are: Rupture of cerclage during the surgery (at time of implantation) Number of wire cerclages used implant used for osteosynthesis (nail or plate) Using of screw fixation operative time
• Assess physicians satisfaction regarding the use of "Sterile Self Locking Polymer Cerclage System [During surgery (at D0)]: Physicians satisfaction regarding the use of "Sterile Self Locking Polymer Cerclage System" will be assessed on: Global satisfaction of the surgeon Ease of use Ancillaries (Cable Passer, Tensioner) : ease of use and lightweight Ease of tension control by the surgeon using tensioner Ease of tracking of the cerclage on radiography Resistance over time (at least until bone consolidation) Presentation (ease of unwinding, packaging)
