A number of investigations revealed a problem of osteopenic syndrome in patients with multiple sclerosis but there is no common opinion concerning factors which lead to its development. We observed 65 patients with multiple sclerosis with various type of its course and disability status of several degree based upon EDSS scale. Ultrasound osteometry of the calcaneus, computer tomography of QCT of L1—L3 vertebras were performed, serum crosslaps, N-MID osteocalcin were used. Decreased bone density, injured bone microarchitectonics and suppression of bone formation and resorption, which were correlated EDSS were found. Correlations with other factors (growth, weight, gender, and number of steroid therapy sessions ) for these parameters was not revealed. This allowed to conclude that the main reason of decreased bone mass in patients with multiple sclerosis is the dramatic decrease in physical activity.

Aims Surgeons and most engineers believe that bone compaction improves implant primary stability without causing undue damage to the bone itself. In this study, we developed a murine distal femoral implant model and tested this dogma. Methods Each mouse received two femoral implants, one placed into a site prepared by drilling and the other into the contralateral site prepared by drilling followed by stepwise condensation. Results Condensation significantly increased peri-implant bone density but it also produced higher strains at the interface between the bone and implant, which led to significantly more bone microdamage. Despite increased peri-implant bone density, condensation did not improve implant primary stability as measured by an in vivo lateral stability test. Ultimately, the condensed bone underwent resorption, which delayed the onset of new bone formation around the implant. Conclusion Collectively, these multiscale analyses demonstrate that condensation does not positively contribute to implant stability or to new peri-implant bone formation.
