Due to the difficulties in obtain bone specimens in Taiwan, this study use reaction molding technique to fabricate the synthetic femur. These synthetic femora are not only suitable for medical and biomedical engineering researches, but also can be used as the teaching and simulating aid in orthopedic. The reason to apply reaction molding process in thsi study is not only the low cost of the reaction materials, but also the room temperature and low-pressure manufacturing requirements, hence make it suitable for the laboratory environment. 　　This synthetic femur includs both the spongy bone and compact bove structures. The elastic modulus of the spongy bone ranged from 140 to 200 MPa while the elastic modulus of the compact bone ranged from 2.9 to 3.5 GPa. From the experimental strain analysis, the reduced elastic modulus in synthetic compact bone is the major contributor in causing the difference of synthetic and real femur in the strain experiment performance. The increasing of elastic modulus in synthetic compact bone should be the first target in future improvements.
