Summary

This is a multicenter, prospective, Post-market Clinical Follow-up (PMCF) Study on the ZNN Bactiguard Antegrade Femoral Nails. The objective of this study is to collect data confirming the safety, performance, and clinical benefit of the study device and instrumentation when used for the temporary internal fixation and stabilization of femoral fractures and osteotomies. This is a CE-marked device already available on the market and the aim of the study is to comply with the post-market surveillance requirements.

Detailed description

This study is a multicentre, prospective, post-market clinical follow-up study on the Zimmer Natural Nail (ZNN) Bactiguard Antegrade Femoral Nails. The primary endpoint for this study is the assessment of performance by analyzing fracture healing within 12 months after fracture fixation. Fracture healing will be analyzed radiologically by the RUSH score adapted to the femur and clinically by the Fix-IT score. The secondary endpoint is the assessment of safety, clinical benefit, and post-op fracture-related infection (FRI). Safety will be evaluated by recording and analyzing the incidence and frequency of complications and adverse events. Relation of the events to implant, instrumentation and/or procedure should be specified. Clinical benefit will be assessed by recording patient-reported outcome measures (PROMs). FRIs will be classified according to the updated diagnostic algorithm defined by the FRI Consensus Group. Data will be collected at 6 weeks, 3 months, 6 months and 1 year after fracture fixation. The study will enroll patients implanted with the Zimmer Natural Nail Bactiguard Antegrade Femoral Nail according to the approved/cleared indications. The sample size for this study is 100 study cases, and up to 10 sites in EMEA will participate.
