Notably, the score attempts to provide a somewhat more objective view of bone apposition, which we believe to be better than subjective interpretation by the investigator.
The short-stem implant led not only to a more physiological stress distribution but also to bone apposition (increase of 20 70% bone density) in the superior resurfaced head, when the stem bone contact prevailed.
In fact, Bidyut Pal and coworkers showed that bone resorption was considerably less for short-stem designs; the short-stem design having stem-bone contact not only led to a more physiological stress distribution but also to bone apposition in the superior side of the resurfaced head [ 26].
The other three drugs used in our therapeutic protocols, are doxorubicin, cisplatin and ifosfamide, and they can also diminish bone apposition; their effects on bone resistance become more evident with advanced age [8].
Based on the current findings in an experimental goat model, it appears that the effect of drilling tissue/bone out of the longitudinal grooves has a more significant impact on the retention force required to remove the stem than the amount of bone apposition outside the stem grooves.
Also, we only measured the bone apposition in one position along the diaphysis and our micro CT analyses have shown some more effects on the proximal tibia.
These studies suggest that the ultra-short implant (which has a more anatomical proximal fit without having a diaphyseal stem with distal cortical contact) can provide immediate postoperative stability and a more physiological load distribution, thus increasing periprosthetic BMD in the medial regions over time, preserving bone mass and stimulating trabecular bone apposition.
Early bone apposition in vivo on plasma-sprayed and electrochemically deposited hydroxyapatite coatings on titanium alloy.
Degradability is among the most important properties in the biomedical field, which is crucial to bone apposition on implants, bone-implant bonding and implantation longevity.
We then analyzed the applied strains, cycles, and periosteal bone apposition rates from the previous studies.
