Abstract

Absorptive devices are often used to treat facial bone fractures in Japan. Only a few reports have investigated whether the plate used was absorbed. In the present study, we used OSTEOTRANS MX® for 13 cases of facial bone fractures at our hospital and studied the progress of the decomposition in the plate body and screw, which required removal due to postoperative infections. OSTEOTRANS MX® was decomposed in the body. The molecular weight of poly-L-lactic acid was reduced and it was finally absorbed; however, unsintered hydroxyapatite was not completely absorbed. In patients in whom the OSTEOTRANS MX® was used, absorption may be completed between 5 to 6 years. However, in certain cases, it takes more than 5 to 6 years. It is necessary to conduct follow-ups until OSTEOTRANS MX® is absorbed and replaced with bone.
