Mg-containing Biodegradable Polymer Bone Repair Material
February 24, 2023 updated by: Shenzhen Zhongke Jingcheng Medical Technology Co., Ltd
The subjects of this study are patients with non-load-bearing bone defects of the extremities who need bone grafting surgery.
The patients was treated with bone graft using magnesium containing biodegradable polymer bone repair material produced by Shenzhen Zhongke Jingcheng Medical Technology Co., Ltd.. Three follow-up visits were performed at the 12th, 24th and 36th weeks after bone grafting, the clinical role for bone will be assessed.
Study Overview
Detailed Description
The subjects of this study are patients with non-load-bearing bone defects of the extremities who need bone grafting surgery.
The subjects were randomly divided into experimental group and control group.
The experimental group was treated with bone graft using magnesium containing biodegradable polymer bone repair material produced by Shenzhen Zhongke Jingcheng Medical Technology Co., Ltd., while the control group was treated with bone graft β- Tricalcium phosphate bioceramics were used for bone transplantation.
Three follow-up visits were performed at the 12th, 24th and 36th weeks after bone grafting.
It is estimated that 176 cases will be recruited in total, and 135 cases have been recruited since April 2021.
This product can be degraded and absorbed in vivo, and it can promote the formation of new bone.
