Estimating the term…
A femoral head support device, in particular a mineralized collagen-based femoral head support device applicable to the treatment of early osteonecrosis of femoral head. The device is made from a dense, homogeneous organic/inorganic composite, wherein the organic phase includes collagen and inorganic phase includes nano calcium phosphate salt, and the device is of a cylinder having an upright through hole and also has a support strength of up to 4000-6000N. By implementing a method for manufacturing such mineralized collagen-based femoral head support device, the mineralized collagen-based femoral head support device with mechanical properties equivalent to human cortical bone can be manufactured; and the mineralized collagen-based femoral head support device can meet the demand for clinical treatment of early osteonecrosis of femoral head to avoid the continuous collapse of necrotic femoral head.
