Intended Use

The DePuy Synthes MAXFRAME™ Multi-Axial Correction System is intended for external fixation of fractured long bones and bones of the foot, limb lengthening, and deformity correction in adult, children* (3-12), and adolescent* (12-21) patient populations. The DePuy Synthes MAXFRAME™ Multi-Axial Correction System utilizes software for assisting surgeons in treatment planning. *in which the growth plates have fused or will not be crossed.

Device Story

External ring fixation system for orthopedic deformity correction and fracture management. Inputs: patient anatomical data used in web-based software for treatment planning. Operation: surgeon assembles modular frame using rings, plates, transfixion wires, Schanz screws, and pins; six telescoping struts connect upper and lower rings in a 'Stewart Platform' configuration. Output: mechanical stabilization and multi-axial correction (length, rotation, angular) via strut adjustment. Used in clinical settings by surgeons to treat bone/soft tissue deformities and fractures. Benefits: modularity allows patient-specific frame construction; simultaneous multi-planar correction.

Clinical Evidence

No clinical data. Substantial equivalence determined via bench testing only, including static/dynamic compression, torsion, cantilever, fatigue, wire slip, and ring-to-wire interface testing.

Technological Characteristics

External ring fixation system. Materials: aluminum, elgiloy, stainless steel, polymers. Design: modular rings, plates, telescoping struts (Stewart Platform). Connectivity: web-based software for treatment planning. MR Conditional per ASTM F2503-13. Software lifecycle per EN IEC 62304:2006-05.

Indications for Use

Indicated for adults, children (3-12), and adolescents (12-21) with fused growth plates or where hardware does not cross growth plates for: fracture fixation (open/closed), pseudoarthrosis of long bones, limb lengthening (epiphyseal/metaphyseal distraction), joint arthrodesis, infected fractures/nonunions, correction of bony/soft tissue deformities, and correction of segmental defects.

Regulatory Classification

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.

| DEVICE DESCRIPTION | The DePuy Synthes MAXFRAME™ Multi-Axial Correction |
| | System, with adult and pediatric indications, is an external ring |
| | fixation system that is combined with web-based software in |
| | treatment of soft tissue and bone deformities. In the |
| | MAXFRAME system, implanted transfixion wires, Schanz screws |
| | and pins are attached to the rings and plates surrounding the |
| | deformity using bolts, nuts and connecting plates. Upper and |
| | lower rings are then connected to one another using six |
| | telescoping struts, creating a "Stewart Platform" type device. |
| | Adjusting the strut length allows for correction of length, |
| | rotation, and angular deformity at the same time. The modular |
| | nature of a ring fixation frame allows multiple frame options. A<br>ring fixation frame is assembled individually by the surgeon to |
| | address the different characteristics of each case. The materials |
| | of construction for this system include aluminum, elgiloy, |
| | stainless steel and various polymeric materials. This system has |
| | been validated as MR Conditional. |
| INTENDED USE | The DePuy Synthes MAXFRAME™ Multi-Axial Correction System is intended for external fixation of fractured long bones and bones of the foot, limb lengthening, and deformity correction in adult, children* (3-12), and adolescent* (12-21) patient populations. The DePuy Synthes MAXFRAME™ Multi-Axial Correction System utilizes software for assisting surgeons in treatment planning.<br>*in which the growth plates have fused or will not be crossed. |
| INDICATIONS FOR USE | The DePuy Synthes MAXFRAME™ Multi-Axial Correction System is indicated for the following treatments in adults, and in both children (3-12) and adolescents (12-21) in which the growth plates have fused or will not be crossed with hardware: fracture fixation (open and closed) pseudoarthrosis of long bones limb lengthening (epiphyseal or metaphyseal distraction) joint arthrodesis infected fractures or nonunions correction of bony or soft tissue deformities correction of segmental defects. |
| COMPARISON OF<br>TECHNOLOGICAL<br>CHARACTERISTICS<br>WITH THE PREDICATE<br>DEVICES | The DePuy Synthes MAXFRAME™ Multi-Axial Correction System has similar intended use, indications, design characteristics, functionality, materials, and performance characteristics in comparison to the predicate devices. The following assessments have been completed to demonstrate substantial equivalence performance specifications: Construct testing (ASTM 1541-02 2011) and component testing including Static & Dynamic Compression testing, Static Torsion, Static Cantilever, Static and Dynamic Fatigue, Wire Slip and Ring to Wire Interface Testing System Validation Software Verification (in accordance with Special Controls & EN IEC 62304:2006-05 Medical device Software life cycle processes) MR Conditional Technical Data (in accordance with FDA Guidance and ASTM F2503-13) Reprocessing of SUD in accordance with Special Controls |
| CLINICAL EVAL | Clinical testing was not necessary for the determination of substantial equivalence. |
| CONCLUSION | The objective evidence presented demonstrates that the mechanical performance of the proposed device is comparable to that of the predicate device(s) and supports substantial equivalence for safety and effectiveness. The proposed device has a similar intended use, indications for use, and |
