DePuy Mitek 231818 MILAGRO ADVANCE Interference Screw – 9mm x 23mm Biocryl Rapide

DePuy Mitek MILAGRO ADVANCE™ BR | 9mm x 23mm | BIOCRYL® RAPIDE™ | 231818 | BX/1

The DePuy Mitek 231818 (MILAGRO ADVANCE™) represents the next generation of biocomposite interference fixation. Engineered for the high-strength stabilization of soft tissue or bone-tendon-bone (BTB) grafts, this 9mm x 23mm screw is constructed from BIOCRYL® RAPIDE™. This proprietary blend of 30% Beta-Tricalcium Phosphate (β-TCP) and 70% PLGA provides the rigid initial fixation required for ACL/PCL reconstruction while offering an osteoconductive scaffold that promotes natural bony ingrowth as the implant absorbs over time.

The "ADVANCE" design features a significantly increased thread pitch and specialized distal-tip geometry. This allows for 83% less effort during initial bone engagement and cuts total insertion time in half compared to traditional interference screws, reducing the risk of graft laceration and driver-induced torque stress.

Key Specifications

• Manufacturer: DePuy Mitek (Johnson & Johnson)

• Product Type: MILAGRO ADVANCE™ BR Interference Screw

• Material: BIOCRYL® RAPIDE™ (70% PLGA / 30% β-TCP)

• Dimensions: 9mm Diameter x 23mm Length

• Absorption Type: Bio-absorbable / Osteoconductive

• Drive Type: Cannulated (Compatible with 1.1mm Nitinol guidewires)

• Quantity: Single Sterile Unit

Technical & Clinical Advantages

• Rapid Insertion Technology: The aggressive thread pitch allows for insertion approximately 2x faster than standard screws. This minimizes the duration of mechanical stress on the graft and reduces "hand fatigue" for the surgeon during high-torque femoral or tibial fixation.

• Osteoconductive Matrix: The 30% β-TCP component provides a mineral-rich environment that helps neutralize the local acidic environment during PLGA absorption. This promotes a more robust ossification within the implant site, leading to a more natural biological repair.

• Atraumatic Threadform: The threads are specifically rounded to maximize interdigitation with the graft and tunnel wall without "cleaving" or "sawing" the delicate soft tissue fibers of an autograft or allograft.

• Effortless Bone Engagement: The unique distal-tip geometry is designed to "self-start" in even the densest cortical bone, ensuring a flush-seated finish that prevents hardware prominence or irritation at the tunnel entrance.

• Cannulated Precision: The hollow core allows for precise delivery and alignment over a standard guidewire, ensuring the screw stays centered within the tunnel to prevent graft "divergence."

Applications

• Knee: Anterior Cruciate Ligament (ACL) and Posterior Cruciate Ligament (PCL) reconstructions.

• Ligamentous Repair: Medial Patellofemoral Ligament (MPFL) and Multi-ligamentous knee reconstructions.

• Shoulder: Proximal Biceps Tenodesis and heavy-duty soft tissue-to-bone transfers.
