Time-dependent mechanical properties of HA/TCP particles in relation to morsellized bone grafts for use in impaction grafting.
In reconstructive surgery human bone defects are sometimes filled with the use of the impaction bone grafting technique. Currently different types of biomaterial particles are being developed as bone-substitute materials. Before these biomaterials can be applied their mechanical and biological behavior should be characterized. In this study the time-dependent mechanical behavior of biomaterial ...
متن کاملReconstruction of the anterior cruciate ligament:a comparison between bone-patellar tendon-bone grafts and four-strand hamstring grafts
Background :Disruption of anterior cruciate ligament (ACL) is a common ligamentous injury of the knee. The choice of graft for (ACL) reconstruction remains controversial. This prospective, randomized clinical trial aimed to compare clinical results of bone-patellar tendon-bone (BPTB) grafts and four-strand semitendinosus-gracilis (ST) grafts for ACL reconstruction over a 3-year follow-up inte...
متن کاملMechanical considerations in impaction bone grafting.
In impaction grafting of contained bone defects after revision joint arthroplasty the graft behaves as a friable aggregate and its resistance to complex forces depends on grading, normal load and compaction. Bone mills in current use produce a distribution of particle sizes more uniform than is desirable for maximising resistance to shear stresses. We have performed experiments in vitro using m...
متن کاملThe influence of avascularity on the mechanical properties of human bone-patellar-tendon-bone grafts.
Our aim was to analyse the effect of avascularity on the morphology and mechanical properties (tensile strength, viscoelasticity) of human bone-patellar-tendon-bone (BPTB) grafts in vitro. These were harvested at postmortem and stored submerged in denaturated human plasma at a constant pH, pO2, pCO2, temperature and humidity under sterile conditions. Mechanical testing was performed two and fou...
متن کاملImplant bone reconstruction using allogenic bone grafts
t implant bone reconstruction using allogenic bone grafts is a technique based on, not only the bone regeneration advantages, but also those of the tissue increase to correct the bone volume lacks in the peri-implant areas. This is about an increase in width of the alveolar crest by adjunctions of allogenic bone grafts which are first adapted to the local tissues and then stabilized with micros...
