Abstract
|
|
|
The purpose of this study was to see the host-bone response to pure titanium fiber-metal surrounding titanium alloy core and rough-blasted titanium alloy(Ti-6Al-4V) implants placed in the medullary cavity of distal femur of rabbit. Each rod was
implanted into medullary cavityof right distal femur through the knee. A total of thirty New Zeaaland rabbits were used. Fiber-metal rods were inserted into fifteen femurs and remaining fifteen were for rough blasted rods. The rabbits were
sacrificed at
one, two, four, six, and twelve weeks after operation and thespecimens were studied histologically. Percentage implant perimeter surface length in contact with new bone were measured. Histomorphometric study showed excellent osseointegration onto
rough-blasted titanium compared to that of fiber-metal titanium rod. When whole group means were compared, it was fund that 36.5 per cent of perimeter of the rough blasted implants was covered with bone compared with 19.2 per cen of the perimeter
of the
fiber-metal coated implants. Peripheral bone formation and osseointegration was evident at one week after implantation and quantitative plateau was reached at four weeks. There
study poved that nonporous-coated rough blasted titanium surface showed evidentosseointegration which is not inferior to fiber-metal titanium surface. We have radiographic and clinical evidence that hip prostheses with rough-blasrted titanium
surface
show osseointegration. The manufacturing cost of porous-coated prosthesis is high and the adverse effects of it are many. The use of rough-blasted surface may help to improve the functional outcome of total joint replacements and reduce the cost
of
arthroplasty.
