Official patent title

Organic biomaterial for bone and joint replacement

Arabic title: مادة حيوية عضوية لاستبدال العظام والمفاصل

Invention

Problem

Conventional bone and joint replacement materials may present limitations involving brittleness, difficult removal, heat generation, petroleum-derived constituents, or uncertain biological integration.

Why it matters

A moldable material based partly on renewable biological feedstocks could broaden research into implants, bone fillers, and joint-repair components if safety and performance are established.

Approach

The disclosure combines nano-sized cellulose or starch from plant and animal-derived sources with natural pigments, antioxidants, adhesives, plasticizers, calcium oxide, and optional polymers. The mixture is molded and cured thermally or with light into a proposed bone or joint replacement biomaterial.

Who may benefit

Potential beneficiaries include biomaterials laboratories, orthopedic implant developers, tissue-engineering researchers, veterinary device teams, and manufacturers evaluating bio-derived composite feedstocks.

Potential value

The concept combines several agricultural or animal-derived constituents with moldable binders and curing options in a single proposed replacement-material platform.

Background

Background

Bone cements and replacement materials must provide workable handling, structural support, and compatibility with surrounding tissue. The disclosure identifies drawbacks associated with some conventional formulations, including exothermic curing, brittleness, difficult revision, and reliance on synthetic constituents. It proposes using cellulose, starch, mineral material, pigments, antioxidants, adhesives, and plasticizers obtained from varied biological sources. The supplied evidence describes the formulation concept and preparation route but does not establish mechanical strength, degradation behavior, sterility, biocompatibility, or clinical performance.

Technology overview

Technology overview

Candidate cellulose or starch sources include date seed, durum seed coat, moringa seed, fish bone, sheep jawbone, and olive seed. Acid hydrolysis can produce nano-sized material, which is dried and blended with selected pigments, antioxidants, biological adhesives, starches, glycerin, plasticizer, calcium oxide, and optional PVC or acrylic components. The blend is placed in a mold and photo-cured or thermally cured. The patent defines ingredient alternatives and processing steps rather than a validated implant specification.

Potential applications

Potential applications

  1. Research prototypes for bone-defect filling materials.
  2. Candidate molded components for joint-replacement studies.
  3. Bio-derived composite research for orthopedic devices.
  4. Material-screening platforms for tissue-engineering laboratories.

Evidence-supported advantages

Evidence-supported advantages

  1. The formulation can incorporate multiple renewable biological sources.
  2. Molding and either thermal or photo-curing are contemplated.
  3. The disclosure offers several natural adhesive and plasticizer alternatives.
  4. Calcium-containing and optional polymer components can be selected for formulation studies.

Development stage

Development stage

A formulation and molding process is described at patent level; mechanical, biological, in-vivo, sterilization, and clinical validation are not established in the supplied evidence.

Commercial opportunity

Commercial opportunity

The concept may interest orthopedic biomaterial and bio-composite developers, but commercialization requires defined composition, reproducible manufacturing, mechanical and fatigue testing, degradation and extractables studies, sterilization validation, biocompatibility, animal studies, regulatory review, and clinical evidence. No implant safety or performance claim has been independently verified in the supplied record.
