There is as yet no clinical trial on the efficacy of different antibiotic regimens in preventing infection in long-bone prosthetic reconstruction.
During the early stages an intense hypervascular aspect at the bone-prosthetic interface is observed.
(181 363 kg) and serves to promote bone ingrowth at the bone-prosthetic interface and to induce bone hypertrophy according to Wolff's Law.
By using a short traction bar the ongoing compressive force generated by Belleville washers stimulates osseointegration at the bone-prosthetic interface [ 8, 9] and promotes hypertrophy of the loaded bone.
When the ultrasound specialist is not familiar with the device, the image obtained during the development of the uncalcified callus may be misdiagnosed as a local recurrence due to the hypervascular aspect at the bone-prosthetic interface.
The addition of porous- or hydroxyapatite-coated collars at the bone-prosthetic interface seems to hold the promise of improving longevity of conventional cemented or uncemented stems [ 9, 34, 46].
A recently developed strategy is compliant compressive fixation that uses compression, via a short traction bar, to stimulate osteointegration at the bone-prosthetic interface, promote hypertrophy of the loaded bone, and avoid stress bypass of the host bone around a stiff intramedullary stem [ 2].
I assessed postoperative radiographs at 3- to 6-month intervals for indications of technical error (pin malposition or migration) and for evidence of device-related failure (lucency at the bone-prosthetic interface, endosteal erosion, loss of compression distance, gross loosening, and implant breakage).
When defining the ingrowth stages there was neither interobserver nor intraobserver variability, ICC 2.1 consistency of 1. Furthermore during the radiographic evaluation signs of loosening were sought as previously suggested in literature [ 6] fracture, transverse pin migration, and progressive radiolucency at the bone-prosthetic interface.
A surgeon places a titanium screw in the jaw bone, and prosthetic teeth are secured to the implant.
