OSsIRIS Study - A Post-market Clinical Follow-up Investigation.

This is a prospective, observational, non-randomized, multicenter, international post-market clinical follow-up investigation aiming to confirm the performance and safety of the bone substitute b.Bone after implantation in patients in isolation or as a graft expander requiring bone grafting for the treatment of surgically created bone defects or bone defects/voids resulting from traumatic injury to promote healing in the pelvis, upper and lower extremities. Patients enrolled in this clinical investigation will undergo orthopaedic surgery with b.Bone as recommended by the specialist and according to orthopaedic standard procedures. Patients will be evaluated preoperatively and at different time points after the surgery according to the standard practice of the sites. The expected schedule is at month 3, month 6 and month 12. Patients who require longer follow-up and could be subjected to metalwork removal will be evaluated up to 24 months. All safety data will be collected from patient inclusion to the end of the clinical investigation. All study visits will coincide with any of the patient's routine clinical visits, without interfering with the investigator's clinical duties. It is planned to enroll 135-193 patients from approximately 15 EU and UK sites.
