Abstract

Bone damage caused by trauma or accidents, along with the limitations of conventional treatment methods, has driven the development of more efficient bone repair strategies. Injectable Bone Substitutes (IBS) offer a minimally invasive alternative with promising clinical potential. This study aims to investigate the physical and chemical characteristics of IBS synthesized from Pinctada maxima shell-derived bioceramics, with modified concentrations of polyvinyl alcohol (PVA) as a binder component. IBS formulations were prepared by varying PVA concentrations from 0% to 12%. The resulting materials were characterized by measuring viscosity, density, injectability, and pH to evaluate their suitability as injectable bone substitutes.The addition of PVA significantly influenced the properties of the IBS. Viscosity values ranged from 0.03 to 99.77 dPa·s, with all formulations exhibiting injectability above 90%. The density values varied between 0.219 and 1.01 g/cm³, while pH values were close to neutral (around 6). The 10% PVA formulation exhibited the most favorable characteristics, with a viscosity of 25.80 dPa·s and injectability of 98.82%, suggesting optimal performance for physiological application. The modification of PVA concentration effectively tailors the physical properties of IBS materials. Further research is recommended to include setting time analysis and more in-depth pH and injectability studies to validate the material’s potential as a biocompatible injectable bone substitute.

Abstract

Kecelakaan merupakan kejadian yang tidak dikehendaki yang dapat terjadi saat sedang bekerja. Banyak warga Desa Kuranji menjadi nelayan dan beresiko mengalami cedera saat bekerja. Tujuan dari pelatihan ini adalah agar warga desa dapat memberikan pertololongan awal pada kasus trauma dislokasi dan patah tulang dengan baik. Metode pengabdian dilakukan dengan memberikan materi dan pelatihan langsung (hands on) kepada kader dan warga tentang cara pemasangan bidai pada kasus trauma dislokasi dan patah tulang. Pelatihan pemasangan bidai dilakukan kepada 34 kader posyandu dan warga Desa Kuranji. Pelatihan berjalan dengan lacar, diisi dengan diskusi serta tanya jawab, dan pelatihan langsung bagi warga untuk mempraktekkan cara memasang bidai pada pasien simulasi. Semua kader dan warga yang hadir antusias dan dapat melakuka pemasangan bidai dengan baik
