Get CatalogAn authoritative overview for hospital procurement directors, orthopedic OEMs, and medical device distributors navigating material shifts, regulatory compliance, and additive manufacturing adoption.
The transition from conventional plasma-sprayed coatings to 3D Electron Beam Melting (EBM) and Direct Metal Laser Sintering (DMLS) trabecular titanium is revolutionizing primary biological fixation. Porous structures with 60–80% porosity and mean pore sizes of 300–600 μm closely mimic human cancellous bone, significantly reducing stress shielding and promoting rapid vascularization and long-term osteointegration.
Ultra-High Molecular Weight Polyethylene (UHMWPE) cross-linking technology (XLPE) combined with Vitamin E stabilization has dramatically lowered wear rates to under 5 mm³ per million cycles. Concurrently, ceramic-on-ceramic (CoC) and ceramic-on-cross-linked-polyethylene (CoPE) bearing surfaces are experiencing double-digit procurement growth due to zero osteolysis risk in younger, more active patient cohorts.
Global medical device regulators—including the European Union (EU MDR 2017/745), US FDA, and India CDSCO—have escalated requirements for clinical evidence, post-market surveillance (PMS), and biocompatibility testing (ISO 10993). OEM buyers are consolidating supply chains around established manufacturers capable of providing robust Technical Dossiers, CE Mark certifications, and full batch traceability.
Our OEM/ODM acetabular cup systems undergo rigorous computational stress analysis, microstructural characterization, and automated surface treatment to maximize mechanical survival and primary stability.

Initial mechanical stability is the single critical determinant for secondary biological fixation in cementless hip replacement. Sharma Orthopedic’s proprietary OEM acetabular shell geometry features an optimized equatorial press-fit allowance (0.5 mm to 1.0 mm line-to-line oversize). This produces controlled polar clearance while generating ideal hoop stress within the acetabular rim, reducing interfacial micro-motion below the critical 28 μm threshold necessary for direct osteoblast apposition.
Additionally, our multi-hole revision cups feature pre-machined countersunk screw holes designed to accept 6.5 mm cancellous bone screws at variable trajectory angles (up to 15 degrees of freedom), empowering orthopedic surgeons to secure rigid anchor points in complex pelvic reconstruction cases without damaging the internal polyethylene locking mechanism.
From initial 3D CAD modeling and prototype validation to high-volume 5-axis machining, laser marking, and cleanroom sterile packaging, we serve as a full-service manufacturing partner.
Our dedicated engineering team utilizes advanced finite element analysis (FEA) software to simulate stress distribution across custom cup geometries. We rapidly turn around functional prototypes for biomechanical testing, helping OEM clients reduce time-to-market for proprietary implant lines.
Operating multi-axis DMG MORI and Mazak CNC centers in our 62,391 sq. ft. campus, we achieve micro-inch surface tolerances on spherical articular surfaces and precise locking grooves, ensuring seamless component interlock.
Products are cleaned using multi-stage ultrasonic aqueous washing and sealed within validated double blister Tyvek® packaging inside controlled ISO Class 7 cleanrooms, meeting international sterile product distribution regulations.
We provide complete white-label manufacturing, custom laser etching (UDI codes, batch numbers, logo branding), and complete Technical Documentation (STED format) to accelerate your local health authority product registration.
Answers to key technical, quality assurance, regulatory, and logistics queries for orthopedic implant procurement officers and distributors.
We strictly utilize implant-grade raw materials sourced from certified suppliers. Metallic shells are forged from Titanium alloy Ti-6Al-4V ELI (ASTM F136 / ISO 5832-3) or CoCrMo (ASTM F75). Polyethylene inserts are machined from medical-grade UHMWPE (ASTM F648) or highly cross-linked polyethylene (XLPE) infused with Vitamin E for maximum oxidative degradation resistance.
We offer multiple surface enhancement options: (1) Vacuum Plasma Sprayed (VPS) pure titanium coating with 30-50% porosity; (2) Dual-layer VPS Titanium + Hydroxyapatite (HA) coating (ISO 13779); and (3) Additive Manufactured 3D porous trabecular titanium mesh structures integrated directly into the shell wall during 3D printing.
Every production batch undergoes 100% dimensional verification via Zeiss Coordinate Measuring Machines (CMM), surface roughness profilometry, coating shear strength testing (ASTM F1044), and dynamic fatigue testing according to ISO 7206-4. Our quality management system is certified under ISO 13485:2016.
Yes. We engineer and manufacture complete matching surgical instrument kits—including acetabular spherical reamers, offset cup inserters, trial liners, head trial assemblies, and depth gauges—in custom stainless steel graphic trays suitable for steam autoclave sterilization.
For standard catalog items, standard MOQs start as low as 20 to 50 sets per size. For custom OEM/ODM projects requiring new tooling or custom design validation, typical initial production lead times range from 6 to 10 weeks post drawing sign-off, with repeat batch lead times of 3 to 4 weeks.
We provide comprehensive regulatory technical dossiers, including biocompatibility reports (ISO 10993), sterilization validation protocols (ISO 11137), mechanical fatigue testing data, shelf-life aging studies, and risk management documentation per ISO 14971 to expedite your regulatory approval process.
