Orthopedic surgeons are familiar with trabecular bone surrounding bone screws in the medullary cavity of long bones where the trabeculae are oriented to lines of stress produced by the loads carried by the bone screws discount 100mg dilantin overnight delivery. H4: Prevention of a Foreign Body Response Can Be Achieved Using Calcium Phosphates as the Tissue Contact Material This hypothesis is the basis for much research on calcium phosphates in crystalline forms and amorphous forms such as bioglasses. Most, but not all, authors agree that the current metals, polymers, and ceramics used in joint replacement are walled off by the foreign body defense 198 Olson et al. This prevents a direct bond between the implant and the tissue. When the capsule is thin and threads, holes, or other anchoring shapes are provided, the mechanical fixation has been effective in stabilizing the implants. They are often described as exhibiting osteointegration to indicate that functional anchoring has been achieved. A fibrous capsule is not as rigid as bone, so the capsule thickness is important. The amount of relative motion depends on the capsule thickness and geometry. If the motion is excessive, bone resorbtion can occur. This results in a progressively thicker capsule and has been identified as a mechanism of failure. Demineralized tissue sections can be used to examine the tissue–implant interface if the implant can be demineralized enough to allow microtoming. It is generally agreed that the calcium phosphates of Ca/P ratio between 1. Composites and bioglasses can be difficult to evaluate. Many authors have reported excellent tissue compati- bility when the local tissue chemistry is dominated by calcium phosphates. Tissue compatibility must be combined with tissue attachment for this approach to be successful unless the calcium phosphates can be used to cause tissue regeneration under load-bearing conditions. Unfortunately the bulk calcium phosphates do not have enduring strength, even when prestressed with metals.
