Abstract It is our goal to develop bactericidal bone scaffolds with osteointegration potential. In this study, poly(vinyl alcohol) (PVA) coating (7%) was applied an erythromycin (EM)‐impregnated strontium‐doped calcium polyphosphate (SCPP) scaffold using a simple slurry dipping method. MicroCT analysis showed that PVA reduced the average pore size and percentage of interconnectivity some extent. Compressive strength tests confirmed significantly increased material elasticity slightly...

We previously showed that strontium-doped calcium polyphosphate (SCPP) scaffold with poly(vinyl alcohol) (PVA) coating extended the impregnated erythromycin (EM) release. In this study, we examined bactericidal effect of EM-doped SCPP (SCPP(EM) ) scaffolds PVA in a Staphylococcus aureus (S. aureus) infected mouse pouch. or without 5% EM, and SCPP(EM) coated (with EM) were prepared. Scaffolds implanted pouch BALB/c mice, followed by inoculation 1 × 10(3) colony-forming units S. aureus. Mice...

Background: Treatment for acromioclavicular (AC) joint pain may include distal clavicle excision (DCE). It is possible that DCE can disrupt the surrounding ligaments, leading to increased AC laxity. Purpose: To determine load failure and stiffness of after symmetric resection (ACJR). Study Design: Controlled laboratory study.
