The MJ-FLEX THE NEW METAIZEAU NAIL™ is indicated to treat: - upper extremity and clavicle fractures in all patients except newborns and infants; - lower extremity fractures in pediatic patients, except newborns and infants, where the flexibility of the implant is paramount not to disrupt the growth plate; - lower extremity fractures in small adults where the medullary canal is narrow. ## Device Story Intramedullary implant system for Elastic Stable Intramedullary Nailing (ESIN) fracture fixation; consists of titanium alloy or stainless steel nails and instrumentation. Used by surgeons in clinical settings to stabilize long bone fractures. Implant flexibility allows fixation without disrupting pediatric growth plates; provides mechanical support for bone healing in narrow medullary canals. Surgeon selects appropriate nail diameter/length based on patient anatomy; device inserted into medullary canal to maintain fracture alignment. Benefits include stable fixation, preservation of growth plates in pediatric patients, and suitability for narrow anatomy. ## Clinical Evidence Bench testing only. Mechanical testing performed per ASTM F 1264-16e1 to evaluate strength and load-bearing capacity. Bacterial endotoxin testing conducted to ensure safety. No clinical data required. ## Technological Characteristics Intramedullary nail system; materials include titanium alloy and stainless steel. Design features elastic properties for ESIN. Mechanical performance validated per ASTM F 1264-16e1. Supplied in various diameters and lengths. Non-powered, mechanical fixation device. ## Regulatory Identification A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system. ## Predicate Devices - OrthoPediatrics PediFlex™ Flexible Nail System ([K082375](/device/K082375.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Characteristics
and Substantial
Equivalence | Documentation was provided to demonstrate that the Orthofix MJ-FLEX
THE NEW METAIZEAU NAIL™ is substantially equivalent to the legally
marketed Predicate, OrthoPediatrics PediFlex™ Flexible Nail System
(K082375). Implants and accessories included in the Orthofix MJ-FLEX
THE NEW METAIZEAU NAIL™ and the predicate device are both Smooth
or threaded metallic bone fastener as defined in 21 CFR 888.3040. They
are both elastic nails for internal fixation. The Orthofix MJ-FLEX THE NEW
METAIZEAU NAIL™ is substantially equivalent to the predicate device in
indications for use, site of application, patient population, conditions of
use, mechanical performances, basic design, operating principles,
materials. The Orthofix MJ-FLEX THE NEW METAIZEAU NAIL™ is
similar to its predicate in size and range of variants. Testing in accordance
with ASTM F 1264 shows the mechanical strength of the subject device
to be equivalent or better than the predicate devices. | |--------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| |--------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Performance Data | The potential hazards have been evaluated and controlled through a Risk
Management Plan. | |------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | | All testing met or exceeded the requirements as established by the test
protocols and applicable standards. A review of the mechanical data
indicates that the components of the Subject device are capable of
withstanding expected loads without failure. The Subject device was
therefore found to be substantially equivalent to the Predicates. Clinical
data was not needed to support the safety and effectiveness of the
Subject Device.
The following mechanical testing was performed:
• ASTM F 1264-16e1 "Standard Specification and Test Method for
Intramedullary Fixation Devices" | | | Furthermore, bacterial endotoxin testing was conducted on the Subject
Device, and was found to meet the expected endotoxin limits. | | Conclusion | Based on design, materials, indications for use, technological
characteristics, and comparison to predicate devices, the Subject Orthofix
MJ-FLEX THE NEW METAIZEAU NAIL™ has been shown to be
substantially equivalent to legally marketed predicate device, and is safe
and effective for its intended use. | --- **Source:** [https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/HTY/K173051](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/HTY/K173051) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
