A 47-year-old man underwent ceramic cup arthroplasty when he was 22 years old. Revision total hip arthroplasty was performed 25 years later because of limited range of motion without implant loosening. Histologic examination revealed that the femoral head and ceramic implant were well fixed through a thin fibrous membrane. The energy-dispersive X-ray analysis indicated that calcium and phosphorus were detected in the same peak pattern as cancellous bone in the bone-ceramic interface.

Ceramic cement as a potential stand-alone treatment for bone fractures: An in vitro study of ceramic-bone composites.

Background: A vertebral burst fracture (VBF) treated with vertebroplasty using a ceramic cement consists of four regions; native bone fragments, native ceramic cement, ceramic cement-trabecular bone (ceramic-bone) composite and ceramic-bone interface. Although the mechanical properties of native bone and native ceramic cements have been well investigated, the mechanical properties of ceramic-bone composite and ceramic-bone interface remain unknown. Therefore, the aim of this study was to determine the mechanical properties of ceramic-bone composites and ceramic-bone interfaces.

Purpose: This study investigated the bone integration ability of a biphasic calcium phosphate bioceramic implanted in dental alveolus of rats.
Materials And Methods: A total of 21 male rats were submitted to upper right incisor extraction and implanted with a synthetic bioceramic (Straumann Bone Ceramic). The animals were killed on 7th, 21st, and 42nd day after surgery for light and scanning electron microscopy (SEM) analysis of bone, bioceramic, and soft tissue volume as well as the quality of graft in its interface.

Porous interconnected hydroxyapatite (HA) and HA/tricalcium phosphate (TCP) (60/40) ceramics are promising materials for hard tissue repair. However, the mechanical properties of these materials have not been accurately determined under weight-bearing conditions. In this study, newly developed HA and HA/TCP (60/40) ceramics were used with intramedullary fixation in segmental bone defects of rabbits.
