category: Sports Medicine / Mobility Therapy
focus: ACL Reconstruction
product family: MILAGRO® Bioreplaceable Interference Screws

The MILAGRO^®BR Interference Screw is comprised of BIOCRYL^® RAPIDE™, a second generation Biocomposite material and the #1 Biocomposite Material in the United States¹. Since 2004, Milagro BR Interference Screws have provided orthopedic surgeons with reliable fixation for soft tissue repairs. Now, a published Human CT Imaging study of ACL reconstructions demonstrates that BIOCRYL RAPIDE absorbs and allows for ossification of the implant site in as little as 3 years². Trust Milagro BR, the proven choice in Biocomposite screw technology.

Features & Benefits

•30% Osteoconductive β-TriCalcium Phosphate.

•70% PLGA co-polymer offers improved absorption time relative to PLA polymers¹

•β-TCP has been shown to buffer PLGA as it undergoes the degradation process²

•Micro Particle Deispersion Technology allows for a homogenous blend of β-TCP and PLGA reducing material related stress concentrations, while ensuring close apposition of osteoconductive β-TCP to bone tissue²

•Chamfered proximal end atraumatically interfaces with graft or tendon material.

•Atraumatic threadform for contact with soft tissues.

Axial CT scan of Milagro screw site in Femur at 39 months. Black and gray arrows indicate bone plug and screw site, respectively¹.

A long term, controlled animal study evaluated 3mm diameter BIOCRYL RAPIDE rods implanted in femoral bone. Histologic evaluation revealed progressive absorption from minor changes at 3 months to marked absorption and bone formation within the implant profile at 24 months^3,4.
