ALTA INTRAMEDULLARY ROD SYSTEM by HOWMEDICA CORP.

The Alta® IM Rod System includes rods that are intended to provided temporary stabilization of femoral fractures. The new Alta rods are intended for use in stabilizing various types of fractures, osteotomies, malunions, and nonunions of the proximal, middle, and distal portions of the femur. TThey can be used in procedures such as femoral reconstruction, bone lengthening, ipsilateral neck/shaft fractures, prophylactic nailing of impending pathologic fractures and knee fusions. The rods are inserted into the intramedullary canal using either an antegrade or a retrograde approach.

Device Description

The IM rods in Alta® IM Rod System consist of a family of curved, fluted rods, cross-locking screws and cap screws for intramedullary nailing of femoral, tibial and humeral shaft fractures. This Alta IM Rod line extension is a modification of the currently marketed Alta IM rods and screws cleared under various 510(k) notifications. These new components will retain the major design features of the previously cleared Alta IM rods and screws and will be made from titanium alloy.

The new femoral IM rods will have two anterior/posterior (A/P) proximal holes and two medial/lateral (M/L) distal holes for dynamic or static locking with cross-locking screws. The cap screws will be available in the standard, low profile and extended designs.

AI/ML Overview

I am sorry, but based on the provided text, there is no information about acceptance criteria or a study that proves the device meets any such criteria. The document is a 510(k) summary for the Alta® Intramedullary Rod System, which outlines its intended use, materials, design, and its substantial equivalence to other marketed devices. It does not contain details about specific performance metrics, testing methodologies, sample sizes, or expert evaluations.

Therefore, I cannot provide the requested table or information regarding acceptance criteria and studies.

The Alta® IM Rod System includes rods that are intended to provided temporary stabilization of femoral fractures. The new Alta rods are intended for use in stabilizing various types of fractures, osteotomies, malunions, and nonunions of the proximal, middle, and distal portions of the femur. They can be used in procedures such as femoral reconstruction, bone lengthening/shortening, ipsilateral neck/shaft fractures, prophylactic nailing of impending pathologic fractures and knee fusions. The rods are inserted into the intramedullary canal using either an antegrade or a retrograde approach.

The substantial equivalence of these components is based on an equivalence in intended use, materials, design, and operational principles to Howmedica's Alta® IM Rod System and the Alta® CFX Reconstruction Rod, Richard'sTriMax Nail System, ACE Medical's ART™ Femoral Nail System and Biomet's Retrograde Femoral Nail.

Dear Ms. Kelly:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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 (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major requlations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or requlations.
