This study is initiated with the aim of regulating release silver (Ag) as an antibacterial agent from micro‐arc oxidation (MAO) coating. Herein, external 5 wt% Tin(II) chloride (SnCl 2 ) containing biodegradable polycaprolactone (PCL) layer formed on 0.8 Ag‐incorporated MAO coating by dip method. SnCl addition into PCL provides a steady Ag concentrated simulated body fluid (1.5X SBF) underlying at 37 °C. When rate taken consideration, it quantified 0.0089 and 0.0586 ppm day −1 for PCL‐covered PCL‐free coatings, respectively. It finally concluded that preliminary result this can be promising minimizing in vivo adverse effects + ions arising rapid well maintaining efficacy prolonged periods, which ideal preventing risk postimplantation infections.

Abstract Advancement in medicine and technology has resulted into prevention of countless deaths increased life span. However, it is important to note that, the modern lifestyle altered food habits, witnessed life-style stresses road accidents leading several health complications one primary victims bone health. More often than ever, healthcare professionals encounter cases massive fracture, loss generation critical sized defects. Surgical interventions, through use grafting techniques are necessary such cases. Natural grafts (allografts, autografts xenografts) however, have major drawbacks terms delayed rehabilitation, lack appropriate donors, infection morbidity that shifted focus investigators direction synthetic grafts. By employing biomaterials based on tissue engineering (BTE), provide a more biologically acceptable approach establishing phases healing. In BTE, various materials utilized support enhance regeneration. Biodegradable polymers like poly-(lactic acid), poly-(glycolic poly-( ϵ -caprolactone) commonly used for their customizable mechanical properties ability degrade over time, allowing natural growth. PEG employed hydrogels promote cell adhesion Ceramics, as hydroxyapatite beta-tricalcium phosphate ( β -TCP) mimic mineral attachment, with -TCP gradually resorbing new forms. Composite materials, including polymer-ceramic polymer-glasses, combine benefits both ceramics/glasses offer enhanced biological properties. collagen, gelatin, chitosan matrix attachment formation, also offering antimicrobial Hybrid decellularized retain structure factors, while functionalized scaffolds incorporate growth factors or bioactive molecules further stimulate healing integration. The current review article provides insights could yield revolutionary improvements orthopedic medical fields. introduction section this focuses statistical information requirements globally its impact economy. later section, anatomy human bone, defects diseases pertaining limitations were detailed. Biopolymers, bioceramics, biometals-based discussed depth sections followed. then concludes summary addressing trends future prospects potential transplants.

ABSTRACT Carbon fiber composites are considered ideal candidates for orthopedic implants due to their elastic modulus being similar that of human bone, but the interfacial bonding between carbon fibers and matrix is still a challenge. In this work, multiscaled calcium phosphate dihydrate nanosheets/microsheets (CHPDnm) introduced on surface by one‐step pulsed electrodeposition method (PED), which significantly improves mechanical biofriction properties composites. CHPD nanosheets grow in situ fibers, fiber/matrix interface bonding. microsheets extend into enhance cohesion matrix. The improved synergistic effect microsheets. Compared pristine composites, flexural compressive strength CHPDnm‐reinforced epoxy resin/phenolic resin/pyrolytic (CHPDnm‐CE, CHPDnm‐CP, CHPDnm‐CC) enhanced 18.1%, 118.31%, 218.0% 53.3%, 32.33%, 41.3%, respectively. addition, CHPDnm‐CE, CHPDnm‐CC showed reduction 80.5%, 50.0%, 21.6% wear rate. This work provides practical strategy modification while broadening application as implants.
