The MatrixRIB Endo Thoracoscopic Rib Plating System is indicated for the fixation, stabilization, and fusion of rib fractures and osteotomies of normal and osteoporotic bone.

Device Description

The MatrixRIB Endo Thoracoscopic Rib Plating System consists of a pre-assembled stability plate with threaded locking posts, and locking caps intended for the minimally invasive thoracoscopic fixation and stabilization of ribs. The implants are manufactured from titanium (CPTi4) and titanium alloy (Ti-6Al-7Nb).

AI/ML Overview

The document provided is a 510(k) summary for the MatrixRIB Endo Thoracoscopic Rib Plating System. It discusses the device's indications for use, technological characteristics, and comparison to predicate devices, along with non-clinical performance data.

However, the document states specifically that "Clinical testing was not necessary for the determination of substantial equivalence." This means that there was no study performed to demonstrate the device meets acceptance criteria regarding clinical performance.

Therefore, I cannot provide information on acceptance criteria, a study proving the device meets them, sample sizes, data provenance, ground truth establishment, expert qualifications, adjudication methods, MRMC comparative effectiveness studies, or standalone performance, as these pertain to clinical studies which were explicitly stated as not being performed.

The document does mention non-clinical performance data:

Non-clinical performance data: Biomechanical Cadaveric Testing (Static Compression Bending, Dynamic Compression Bending).
Conclusion from non-clinical data: "The non-clinical performance data demonstrate that the mechanical performance of the proposed MatrixRIB Endo Thoracoscopic Rib Plating System is comparable to that of the predicates."

This implies that the acceptance criteria for non-clinical performance were based on demonstrating mechanical comparability to predicate devices through these biomechanical tests. However, the specific quantitative acceptance criteria and the detailed results showing how the device met these are not provided in this summary.

In summary, based on the provided document:

Acceptance Criteria & Device Performance: Not provided for clinical performance as no clinical study was deemed necessary. For non-clinical performance, the acceptance criteria were implicitly based on demonstrating mechanical comparability to predicate devices. The reported device performance for non-clinical testing was that it is "comparable to that of the predicates."
Sample Size (test set) & Data Provenance: Not applicable as no clinical test set was used.
Number of Experts & Qualifications: Not applicable.
Adjudication Method: Not applicable.
MRMC Comparative Effectiveness Study: No.
Standalone Performance Study: No clinical standalone study presented.
Type of Ground Truth: Not applicable for clinical performance.
Sample Size (training set): Not applicable as no machine learning algorithm or training data is mentioned.
How Ground Truth for Training Set was Established: Not applicable.

Comparison to Predicate Devices:

Indications

The MatrixRIB Endo Thoracoscopic Rib Plating System has the same general Indications for Use as the predicate devices.

Technological Similarities of MatrixRIB Endo Thoracoscopic Rib Plating System to Predicates

Same general principle of operation for all components; provide fixation and stabilization to rib fractures so that fusion may occur.
Both MatrixRIB Endo and RibLoc Systems rely on strong mechanical fixation that lags the plate to the rib.
All Systems are used with smaller incisions allowing a less invasive (RibLoc) or ● minimally invasive (MatrixRIB splint, MatrixRIB Endo) surgical technique to provide access to the fracture and implantation of internal fixation.
For all Systems, same or similar materials used for construction of fixation devices e.g. Titanium and/or Titanium Alloy
The MatrixRIB Endo stability plate lengths are within those of the predicates ●
o All Systems are designed to accommodate the anatomy of the rib
MatrixRIB Endo and RibLoc Systems both have plates that can be contoured both external to the patient and intraoperatively.
Both MatrixRIB Endo and MatrixRIB (splint) are designed to be used without removing periosteum in order to maximize blood supply to the bone.
Both the MatrixRIB Endo and RibLoc Systems "sandwich" the rib; the MatrixRIB Endo, the rib lies between the stability plate placed posteriorly and the locking caps placed anteriorly and the RibLoc, the rib lies between the plate which is placed anteriorly and supports with anterior, superior, and posterior rib surfaces due to its ushaped channel supports.

Technological Differences of MatrixRIB Endo

Stability Plates are pre-assembled with threaded locking posts that can pivot about the ● plate slot to accommodate both the surgical technique and the final implantation
Prior to fixation with the threaded locking caps, threaded locking post slides freely along the plate slot to accommodate intraoperative positioning.
Locking caps are sized to accommodate a variety of rib thicknesses ●
MatrixRIB Endo uses a standard thoracoscopic approach with anterior stab incisions; RibLoc uses a standard thoracoscopic approach with large incision over rib fracture
o MatrixRIB splints are placed into the intramedullary canal of the rib, while the MatrixRIB Endo "sandwiches" the rib; the rib lies between the stability plate placed posteriorly and the locking caps placed anteriorly.

Non-clinical performance data:

Non-clinical testing and analyses comparing the proposed devices to the predicates within this submission include:

Biomechanical Cadaveric Testing ●
o Static Compression Bending
. Dynamic Compression Bending

The non-clinical performance data demonstrate that the mechanical performance of the proposed MatrixRIB Endo Thoracoscopic Rib Plating System is comparable to that of the predicates.

Clinical performance data:

Clinical testing was not necessary for the determination of substantial equivalence.

Substantial Equivalence:

The proposed devices have the same intended use as the predicate devices. The mechanical testing included in this submission demonstrates that:

Any differences in technological characteristics of the predicates do not raise any new questions of safety and effectiveness.
The proposed devices are at least as safe and effective as the predicates.

It is concluded that the information included in this submission supports substantial equivalence.

Regulation Number and Section

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
