ABSTRACT:
Novel composite orthopedic devices with modulus variations are disclosed. The device contains an extraosseous portion attached to a first intraosseous portion which is secured to a second intraosseous portion; the intraosseous portions may interface with the intramedullary canal of the human femur. The modulus varies along the length of the device, decreasing from the extraosseous portion to the second intraosseous portion. The variations in modulus are achieved by forming the device from a composite comprising filaments nonlinearly disposed about the longitudinal axes of the device and within a polymer matrix. The method of making the present orthopedic device is also disclosed.
