Core Insights - Hong Kong University (HKU) has developed a new elastic calcium phosphate "nano-biomimetic bone" material that could address challenges in bone defect treatment [1][3] Group 1: Material Development - The new material serves as an alternative to traditional bone defect surgical materials, significantly reducing surgery time and accelerating postoperative bone healing [1][3] - Current solutions for bone defects typically involve autologous bone (patient's own bone) and allogeneic bone (donor bone), which face issues such as material shortages, immune rejection, and exogenous infections [3] Group 2: Material Properties - The "nano-biomimetic bone" material developed by HKU's team exhibits high elasticity, toughness, and strength, closely resembling the composition and mechanical properties of natural bone, with a similarity rate of 90% [3] - The material is designed to provide high safety and biocompatibility, significantly enhancing patient comfort and mobility [3] Group 3: Project Background - The "nano-biomimetic bone" project was initiated in 2016 and is a collaborative effort between HKU's medical school and related teams at the Hong Kong University Shenzhen Hospital [3]
