MatrixRIB™ Fixation System

The DePuy Synthes MatrixRIB™ Fixation System consists of pre-contoured, shaped, and straight locking plates, locking screws, and intramedullary splints for the fixation and stabilization of the chest wall.

Features & Benefits

The DePuy Synthes MatrixRIB™ Fixation System

Used without removing periosteum to limit disruption of the blood supply to the bone¹
Drill bit with stop to prevent over-drilling
Self-retaining screwdriver blades

Pre-contoured plates

Plates are pre-contoured to fit an average rib shape, which minimizes intraoperative bending^2,3,4,5
Low profile, 1.5 mm thick plates
Plates are colour coded to distinguish left and right designs
Plates are etched on medial end to indicate the corresponding rib curvature

Intramedullary splints

Intramedullary splints allow less invasive procedures^5,6
Three widths available (3 mm, 4 mm, 5 mm)
One screw needed to secure splint

Locking screws

Locking design allows for stable fixation compared to non-locking screws^7,8
Self-drilling Locking Screw option does not require pre-drilling or tapping
Screws work with self-retaining screwdriver blades

Sternal body plates

Plates are shaped for sternal osteotomies and fractures^7,8
2.8 mm thickness for higher loads on sternal body^7,8

Universal/straight plates

A universal plate with 8 holes is available for smaller fracture areas and osteotomies
Straight plates with 24 or 30 holes are available for complex or custom bends

Minimally Invasive Plate Osteosynthesis (MIPO)

MIPO instruments offer additional approach options that are less invasive than the original MatrixRIB Fixation System. These instruments overcome various access challenges by extending their reach without increasing incision size.⁹
