Evaluation of the Safety and Performance of the Neocement® Inject P

Neocement® Inject P represents a breakthrough in orthopaedic biomaterials, meticulously engineered to enhance bone repair and regeneration. This synthetic bone substitute combines tetracalcium phosphate and beta-tricalcium phosphate within its P-system architecture, augmented by chitosan and an aqueous solution enriched with citric acid and glucose.

Neocement® Inject P is indicated for filling bony voids or gaps of the skeletal system that are not intrinsic to the stability of the bony structure. The device may be used for filling surgically created bone defects or osseous defects created from traumatic injury to the bone.

To achieve its intended purpose, Neocement® Inject P will be placed in contact with bone tissue and surrounding tissues by surgically invasive techniques in operating rooms. More than one unit of Neocement® Inject P can be used for filling bony voids or gaps of the skeletal system, depending on the lesion.

Neocement® Inject P is a class III medical device. This advanced biomaterial offers a reliable solution for addressing bone fractures and loss, demonstrating significant potential in enhancing patient outcomes through accelerated and durable bone regeneration. Neocement® Inject P is expected to be partially or totally resorbed, from the clinical available data, the expected effect can be predicted to occur after 6 months.

This observational post-market study will collect data relating to standard practice procedures, therefore there are no additional risks or direct benefits associated with participating in this registry for the patient.

This study based on observations of clinical practice aims to collect clinical data to keep up to date the information on the performance and safety of the medical device when used in accordance with its intended use and current clinical applications. The results of the clinical study shall be used as clinical evidence for clinical evaluation of the device aiming submission to the new Medical Device Regulation (EU) 2017/745.

The post-market study is meant to identify and analyse emerging risks, ensure the continued acceptability of the benefit/risk ratio and also identify possible systematic misuse or unauthorized use of the medical device. This protocol does not include any planned new uses, new populations, new materials or design changes.

The results from the prospective observational post-market study will provide an evidence base for assessing the device's performance and safety after its market launch. Detecting real discrepancies in clinical performance between of the medical device early on can offer valuable opportunities to improve device design. This complements the data collected during the pre-market phases, thus improving patient selection. Active surveillance of the safety of medical devices, achieved through the continuous monitoring of vast sources of clinical data, is a priority in the field of medical devices, a requirement of MDR regulation No. 2017/745. This approach is crucial to achieving the objectives set, guaranteeing the safety and performance of the devices in circulation.

Patients will be followed as per local standard medical practices of the centre for 1 year.

Clinical data will be collected at 4 points in time: Visit 1 (6 weeks ± 2 weeks - enrolment), Visit 2 (3 months ±3 weeks), Visit 3 (6 months ±3 weeks) and if necessary, a Visit 4 (12 months ±30 days).
