Abstract:
The present invention provides processes for combined applications of making grooves on an implant surface, applying MgO nanoparticles with PMMA cement, restricting the cement movement by PCL nanofiber and tethering biomolecules with PCL nanofiber to enhance mechanical stability and osseointegration of PMMA cement with bone. This is achieved through enhanced osteoconductive properties, roughness, and less viable fracture originating sites at the bone-cement interface. Such combined applications of nanoparticle and nanofiber on the mechanical stability and osseointegration of cemented implant is heretofore unknown, but as provided by the present invention can solve the debonding problem of cemented implant from bone.

Claim (Index 16):
An electrospun nanofiber (ENF) membrane, comprising:\n a fiber matrix exhibiting a tubular shape having an inside span and an outside span, said matrix formed by electrospinning nanofibers on to an elongated substrate rotated around a longitudinal axis during electrospinning to produce said tubular shape; multiple layers of nanofibers, each of said layers consisting of generally aligned fiber strands and said fiber strands comprising each layer are collectively positioned at an oblique angle to the fiber strands in each adjacent layer to form said matrix.
