Osteotomy Clinical Trial
Official title:
Post-Market Clinical Follow-up Study on the ZNNā¢ Bactiguard ® Cephalomedullary Nails (Implants and Instrumentation). A Multicenter, Prospective, Consecutive Series
This is a multicenter, prospective, Post-market Clinical Follow-up (PMCF) Study on the ZNN Bactiguard Cephalomedullary 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 trochanteric, sub-trochanteric or shaft 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.

Primary | Performance of the study device by analyzing fracture/osteotomy healing at 12 months after fracture fixation. | Performance will be assessed by analyzing fracture/osteotomy healing at 12 months after fracture fixation. Fracture healing will be assessed clinically and radiologically:
Radiological fracture healing is defined as bridging callus on at least three of the four cortices on the AP. and lateral radiographs Clinical fracture healing is defined as full weight-bearing without pain. |
12 months after fracture fixation | |
Secondary | Safety assessment by recording and analyzing incidence and frequency of adverse events. | Recording and analyzing incidence and frequency of adverse events. | 6 weeks and 3, 6, and 12 months after fracture fixation | |
Secondary | Oxford Hip Score | Patient-Reported Outcome Measures (PROMs) that document hip function and pain. It's used as a surrogate to assess function and pain of the operated limb. | 3, 6, and 12 months after fracture fixation | |
Secondary | EQ-5D Health Questionnaire | Patient-reported outcome completed by the patient. It assesses the general health status of the patient and it can be used to derive a quality of life index used for health economics considerations. | 3, 6, and 12 months after fracture fixation | |
Secondary | Rate of fracture-related infections | Fracture-related infections are diagnosed in accordance with the algorithm described in M McNally, G Govaert, M Dudareva, M Morgenstern, W J Metsemakers, EFORT Open Rev 2020;5:614-619. | 6 weeks and 3, 6, and 12 months after fracture fixation |
