    Notes: A percutaneous implant for the attachment of an artificial limb has been designed and tested in 14 pigs. Firm fixation to beone was achieved with the porous-surface layered metal intramedullary stem design in some cases. Dacron velour was used at the soft tissue interface. Evidence of soft tissue ingrowth was seen. However, the velour was unable to maintain adequate epithelial adhesion to form an anatomical seal and a barrier to bacteria.

    Bone ingrowth and stress shielding with a porous surface coated fracture fixation plate (1979)

    Notes: The extent of bone remodelling under metal fixation plates attached to bone by (i) normal screw fixation and (ii) bone ingrowth into a porous metallic surface underlayer sintered to the metal plate was investigated. Extensive bone remodelling was observed under the integrally bonded porous surface layered plate. This remodelling could be attributed to the more extensive stress transfer from bone to metal plate because of the good bone-to-implant bonding. The importance of stress shielding with high stiffness implants is demonstrated.

    Carbon fiber-reinforced bone cement in orthopedic surgery (1976)

    Notes: A tougher, more fatigue-resistant bone cement consisting of short, highmodulus carbon fibers dispersed randomly in normal poly(methyl methacrylate) bone cement has been developed. Fatigue and impact tests are reported that demonstrate the superior fracture resistance and prolonged load-carrying ability of this system.The use of this carbon fiber-reinforced bone cement in the treatment of a pathological fracture of the femur associated with neoplastic disease of the bone is reported. The tougher cement has provided long-term stability of the fracture.

    Evaluation of a biodegradable ceramic (1977)

    Notes: An evaluation of a porous biodegradable ceramic, tricalcium phosphate, has been carried out. When implanted in cancellous bone, it is rapidly infiltrated with bone and slowly resorbed. When held rigidly against raw, bleeding, cortical bone, again rapid bone ingrowth occurs.The material does not give rise to any untoward tissue reaction, nor does it cause any systemic reaction. It can therefore be concluded that the material is safe for use in clinical practice, and can be used in specific instances either to replace or to supplement bone grafting.

    The rate of bone ingrowth into porous metal (1976)

    Notes: Experiments have been devised to study the rate of ingrowth of bone into porous metal with pore sizes up to 100 μ and to study the significance of a gap between the porous metal surface and bone.When the porous coat was in direct apposition with bone, the implant was firmly locked in place after a three week period and the plateau value of implanttissue shear strength was reached at four weeks. A gap of 1.5 mm between the bone and the implant was bridged by new bone wihtin four weeks.
