Open j.urnal of.Orthopedics 2024年第5期14卷 218-228页

Backg.ound: Early exploration of.the semi constrained “f.oating.Socket” total shoulder replacement (TSR) in 1974 led to a prolif.ration of.various unconstrained desig.s that allowed resection or retention of.the humeral head, depending.upon the patholog.cal process involved. Deg.nerative g.enohumeral arthritis with mild to moderate involvement of.subchondral bone allowed f.r a resurf.cing.option, while severe humeral head involvement required a partial or f.ll humeral head replacement attached to an intramedullary stem f.r f.xation. All components evolved f.om cemented to cementless application by 1982. The purpose of.this paper is to describe the prog.ession of.Buechel-Pappas (B-P) shoulder replacement development f.om the early 1970’s in both cemented and cement less applications. Methods: Clinical evaluations of.“f.oating.Socket” TSR, f.llowed by B-P stem-type, resurf.cing.types, bipolar-type and revision components, all of.which comprise the B-P Shoulder Replacement System, were perf.rmed over a 49-year period. Results: “f.oating.Socket” implants improved the results of.simple, constrained ball-in-socket desig.s, but g.nerally f.iled by g.enoid component loosening.in both chimpanzee and human applications. Unconstrained resurf.cing.type components, both anatomical humeral head and f.ll proximal humeral components, were quite successf.l, with minimal f.ilures observed in long.term studies. Bipolar salvag. implants, used f.r severe proximal def.ciencies, revisions and massive rotator cuf. arthropathy, were also very successf.l;providing.overhead rang. of.motion in many patients. Conclusions: Resurf.cing.hemiarthroplasty, in patients with intact or repairable rotator cuf. mechanisms, g.ve the most satisf.ctory results and were the least technically complicated to perf.rm, requiring.minimal instrumentation. Resurf.cing.of.f.ll proximal humeral def.ciencies, using.f.moral resurf.cing.components, g.ve similar clinical results to more complex semi-constrained devices,

Honeybees (Apis mellif.ra) are important pollinators of.f.owering.plants and ag.icultural crops contributing.annually to billions of.dollars in revenues to crop production. Honeybees have an averag. lif.span between 8 weeks to 5 years. Dead honeybees are abundantly available in beehives and can be utilized as an alternative source to synthesize nanoparticles. In recent years, biolog.cally synthesized nanoparticles have been pref.rred over their chemical counterparts. However, honeybee-based-g.een synthesis of.nanoparticles has not been explored yet. Herein, we report the biosynthesis of.silver nanoparticles f.om honeybees and its antibacterial activity. The synthesis of.silver nanoparticles was monitored visually throug. a g.adual chang. in color. f.rthermore, the biosynthesized nanoparticles were conf.rmed and characterized by UV-visible spectroscopy. Scanning.Electron Microscope was utilized to analyze the averag. size and morpholog.es of.the biosynthesized nanoparticles. Subsequently, the antibacterial potential of.the biosynthesized silver nanoparticles was tested ag.inst selected g.am-positive and g.am-neg.tive bacterial strains. It was f.und that a distinct color chang. f.om yellow to brown in the reaction solution sug.ested the f.rmation of.silver nanoparticles. The biosynthesized nanoparticles exhibited absorption maxima at 430 nm. The SEM analysis conf.rmed the spherical and cuboidal shape of.the biosynthesized silver nanoparticles with a size rang. between 10 - 40 nm. f.rthermore, the biosynthesized silver nanoparticles exhibited strong.antimicrobial potential ag.inst tested g.am-positive and g.am-neg.tive bacteria strains by ag.reg.ting.on the cell surf.ce. This study showcases the biomedical and ag.icultural applications of.biosynthesized silver nanoparticles f.om honeybee wing.. .
