Abstract

Two in-vitro mechanical models and test protocols were developed to analyse the initial mechanical stability of bone graft materials in Impaction Grafting hip revision arthroplasty. Morsellised bone allograft and various mixes with a hydroxyapatite/tricalcium-phosphate (HA-TCP) graft extender were impacted into an ovine and a human geometry model. The samples were cyclically block-loaded in compression and vertical subsidence was recorded. Adding the HA-TCP graft extender to the bone allograft led to reduced subsidence in both models, even at low mixing ratios. Intense impaction was identified as the single most critical factor for achieving initial mechanical stability.
