Winnipeg Free Press (Newspaper) - January 8, 1990, Winnipeg, Manitoba Winnipeg free january n Bon making called creep Over surfaces of old Bone or the hydroxy apatite layer on an artificial hip secreting a layer of protein called the layer is called Bone artificial hip joint scientists have invented an experimental kind of artificial hip joint that tricks True body Bon making cells into producing new Bone firmly attached to old style hip cemented in place or simply forced into the can come the experimental like old is made mainly of but it is coated with a Boelike Calcium phosphate Crystal called the coating encourages new Bone to form on the it works because Bone is a living filled with free roaming cells that break Down old Bone and others that create new molecules of Calcium phosphate in surrounding fluid quickly penetrate the Bone matrix and take up positions in a growing crystalline layer of the Mineral other osteoblasts come along i adding More Bone which encourages More Mineral molecules to join the crystalline thickening the fat free Bone is about 35 percent Collagen and 65 percent Calcium new Bone on joint eventually knits with Bone building up inside Bone cells tricked into hip cure by Susan okie the Washington Post Washington Cal researchers look ing for new ways to treat damaged Bones Are learning to harness the microscopic living sculptors that make Normal Bone free roaming cells that creep around the taking up old Bone and laying Down they Are doing it with new kinds of artificial Bone that Are Chemi Cally so close to the real thing when placed into damaged they can fool the Bon forming cells into making the real Bone knit with the synthetic for the Metal hip or artificial implanted in about Ameri cans a the old which is usually cemented to real often comes causing consid Erable the living part of the Bone sometimes recognizes the Metal As an alien material and produces a fibrous Sheath around it that loosens the thin layer but if the Metal is first coated with a thin layer of the Mineral that gives Bones their the Bon making cells around it seem to embrace the implant As if they recognized the coating As a Friendly if Lon term studies show that the joints stay the coated implants could become the Stan Dard said Randall an orthopaedic surgeon at George Washington University medical school who has implanted the new device in about 30 a medical researchers and Bio technology companies Are using various versions of the artificial Boelike Calcium phosphate in a crystalline form known As to repair defects in various parts of the Skele tooth implants have been on the Market since and for about a Oral surgeons have been using by drop apatite ceramics to fill holes or defects in the a food and drug administration advisory panel recently recommended that a Hydro apatite Ceramic made from be approved to repair some kinds of inject a hydroxy apatite paste called Superb one is being developed by Norian of Mountain the idea is to inject it into Bones that have been thinned or weakened by Stanford University radiologist Stuart Young said the which solidifies within two to three hours once it is in May someday be used to Patch fractures and to strengthen Bones thinned by Osseo a condition that often develops in women after Meno Young said his research shows that when a Core of Bone marrow is removed and replaced with super the cells normally present in the Bone and its blood producing marrow can Tunnel into the super Bone implant and take up Resi Dence Lewis said his results suggest the hip implant May improve the strength and durability of artificial hips for Large or physically Active who experience higher than average failure rates with current in most the top part of the femur or thighbone is sawed off and replaced with a Metal pin that is cemented into the femurs mar Row space using polymath Elmetha which is similar to us the bal shaped head of the pin swivels in a polyethylene cup attached to the the treatment is highly Success Ful for most with a failure rate of about one per cent per but Lewis said More Active who put More stress on their Bones and Are More Likely to suffer pain or loosen ing of the because the Cement is the weak Many Ortho pudists currently treat High risk patients with implants that have a porous surface intended to encourage Bone to grow into the but Lewis said they often fail and the implant becomes sheathed with flexible fibrous allowing it to wiggle and cause for the last re searchers have been searching for a Way to achieve intimate Contact Between Metal and Bone through chemical Lewis coating the Metal with hydroxy apatite appears to provide that hydroxy apatite is a Mineral con Taining oxygen and Hydrogen atoms in a Crys Talline lattice like the crystals make up about 65 per cent of the dry weight of some Bone called Tunnel through old dissolving it As they other the travel Over exposed surfaces and leave behind a porous layer of a protein called atoms of Mineral diffuse into the Collagen and recognizes synthetic hydroxy apatite so resembles the natural substance when implanted in the Bone recognizes this material As a close said John pres ident of in san Kay said his studies show that the Bone cells quickly accept the synthetic surface and that the Bone they produce forms a continuous lattice with crystals in the producing a Strong
