Calcium Phosphate Cement As Bone Void Filler

CALCIUM PHOSPHATE CEMENT AS BONE VOID FILLER - a Prospective Cohort Study in Patients Indicated for Long Bone and Extremity Surgery

This is an observational, prospective, non-randomised, post market clinical follow-up study to compile clinical data on performance and safety of the synthetic bone graft substitute and to assess that the performance and safety of the device are maintained until the reaching of its intended use in a commercial clinical setting in long bone and extremity defects.
