Intended Use

The Precice Max System is indicated for limb lengthening, open and closed fracture fixation, pseudoarthrosis, mal-unions, non-unions, or bone transport of long bones in patients age 18 years and older and indicated for limb lengthening of the femur and tibia in pediatric patients (greater than 12 years old).

Device Story

Precice Max System is an intramedullary fixation device for limb lengthening and bone correction. Device consists of titanium alloy intramedullary nail, locking screws, endcaps, and surgical instruments. Operates via magnetic distraction osteogenesis; external remote controller (ERC) drives internal magnetic mechanism to achieve gradual bone lengthening or compression. Used in clinical settings by surgeons for long bone procedures. Output is mechanical distraction/compression of bone segments. Benefits include controlled limb lengthening and stabilization of fractures or non-unions. Compatible with previously cleared ERC models (ERC 1, 2P, 3P, 4P).

Clinical Evidence

Bench testing only. No clinical data provided. Performance verification included static and dynamic compression bending strength, torsion, dynamic 3-point bending, torque resistance, and axial pullout strength, conducted in accordance with ASTM F1264 and ASTM F543 standards.

Technological Characteristics

Materials: Medical grade titanium alloy (ASTM F136, UNS R56401). Principle: Magnetic distraction osteogenesis. Components: Intramedullary nail, locking screws, endcaps, reusable surgical instruments. Connectivity: Compatible with external remote controllers (ERC). Form factor: Various lengths/diameters/screw hole configurations. Sterilization: Not specified.

Indications for Use

Indicated for limb lengthening, fracture fixation (open/closed), pseudoarthrosis, mal-unions, non-unions, or bone transport of long bones in patients 18+ years; also indicated for femur and tibia limb lengthening in pediatric patients >12 years.

Regulatory Classification

Identification

An intramedullary fixation rod is a device intended to be implanted that consists of a rod made of alloys such as cobalt-chromium-molybdenum and stainless steel. It is inserted into the medullary (bone marrow) canal of long bones for the fixation of fractures.

Dear Miriam Cervantes:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
