Medisplint
Medisplint Orthopedic Instruments Co., Ltd. stands as a premier orthopedic device manufacturer specializing in high-precision implants, fixation systems, and specialized surgical instrumentation for trauma, spine, and joint reconstruction.
Founded in 2016, our enterprise has experienced rapid, continuous growth fueled by innovative biomaterial engineering and strategic international collaborations. Operating a modern, state-of-the-art facility spanning approximately 18,500㎡, Medisplint leverages advanced vertical integration—from material qualification to component design, CNC machining, cleanroom packaging, and rigorous mechanical validation.
We work in lockstep with international medical brands to produce customized PEEK and titanium orthopedic implants. With 68 new product launches in the past year alone, our iterative design speed keeps our clients ahead of market cycles.
Every batch of raw medical PEEK is sourced from leading global suppliers, documented with mill test certificates, and traceably machined to prevent any potential structural degradation or contamination.
The shift from traditional metals and bioabsorbable materials to high-performance Polyetheretherketone (PEEK) represents a monumental change in arthroscopic repair procedures.
PEEK exhibits an elastic modulus (approximately 3.6 GPa unfilled, up to 18 GPa reinforced) that closely mirrors the physical characteristics of human cortical bone. This helps reduce stress shielding, ensuring optimal bone density preservation around the implant site.
Unlike titanium implants, which create significant imaging artifacts on MRI and CT scans, PEEK is radiolucent. This allows orthopedic surgeons to clearly monitor postoperative healing, tissue reattachment, and bone integration over time.
Historically, bioabsorbable polymer anchors (like PLLA or PGA) carried risks of late aseptic inflammatory reactions or premature breakdown. PEEK remains entirely stable and inert in the human body, providing reliable, permanent support.
| Performance Characteristic | Medical-Grade PEEK | Titanium Alloy (Ti6Al4V) | Bioabsorbable Polymers (PLLA/Biocomposite) |
|---|---|---|---|
| Elastic Modulus | 3.6 - 18 GPa (Very close to cortical bone) | 110 - 115 GPa (High stiffness difference) | 5 - 8 GPa (Weakens over time) |
| Radiolucency (MRI/CT) | Excellent (Transparent, zero artifacting) | Poor (Creates severe scatter artifacts) | Excellent (Transparent) |
| Mechanical Stability | Permanent, highly fatigue-resistant | Permanent, prone to micro-motion bone loss | Degrades dynamically, variable strength timeline |
| Tissue Biocompatibility | High inertness, low inflammatory profile | Excellent osseointegration | Risk of localized acidic resorption reactions |
Sourcing orthopedic implants requires thorough validation due to the strict regulatory landscapes of clinical products. Global procurement managers at medical device brands, distribution houses, and large surgical groups evaluate supplier compliance across several key areas:
Facilities must hold ISO 13485:2016 certifications. Products require detailed technical documentation demonstrating CE or FDA compliance for sports medicine devices.
PEEK thread pitches, driver interface geometries (like hex or star drives), and suture eyelets must match exact specifications to prevent failure during insertion.
The connection between the PEEK anchor body and the high-strength suture (such as UHMWPE) must withstand significant tension without fraying or releasing.
Medisplint offers specialized production options for custom clinical demands:
Our quality assurance workflow runs through 42 dedicated testing inspectors and a fully-equipped validation laboratory to verify performance from raw material processing through final packaging.
Every stage of production—from qualifying incoming materials through automated CNC machining to mechanical verification—is managed under strict quality protocols.
PEEK suture anchors are engineered to provide secure soft tissue fixation to bone, supporting healing across key clinical applications.
Ideal for rotator cuff repairs, Bankart lesion repairs, SLAP tears, and biceps tenodesis. PEEK's biomechanical strength helps prevent bone degradation in high-stress joint areas.
Standard sizes: 4.5mm - 5.5mmProvides stable reattachment for Achilles tendon repairs and lateral ankle ligament stabilization (Brostrom procedures), supporting early mobilization protocols.
Standard sizes: 2.8mm - 3.5mmOffers reliable fixation for acetabular reconstruction. The radiolucent properties of PEEK help prevent imaging interference during postoperative joint space assessments.
Standard sizes: 2.4mm - 3.0mmAnswers to common technical, material, and regulatory questions from medical device distributors and sourcing managers.
