The use of unidirectional porous β-tricarcium phosphate in surgery for calcaneal fractures: A report of four cases

摘要

Affinos @ (Kuraray) is a unidirectional porous β-tricarcium phosphate (UDPTCP). We investigated four patients (four feet) who underwent invasive surgery using UDPTCP to treat calcaneal fractures that were accompanied by a bone defect. The mean age was 63.8±6.4 years old, and the mean observation period was 9.3±3.2 months. We evaluated the changes of UDPTCP over time and correction loss due to its use. In all patients, favorable material absorption and bone substitution were obtained, and their clinical courses were also favorable.
