• Device Name: TROCHANTERIC DYAX NAIL SYSTEM
• Applicant: Howmedica Osteonics Corp.
• Product Code: HSB · Orthopedic
• Decision Date: Nov 14, 2001
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 888.3020
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The device is intended for use in stabilizing various types of intertrochanteric fractures of the proximal femur.

Device Story

Trochanteric Dyax Nail System is an intramedullary fixation rod used for stabilizing intertrochanteric fractures of the proximal femur. It serves as a line extension to the Trochanteric Gamma Nail System. The device is surgically implanted by orthopedic surgeons in a clinical or hospital setting. The system utilizes titanium alloy construction, replacing the stainless steel used in the predicate. Design modifications include changes to the proximal diameter and the distal screw hole configuration. The device is compatible with 5 mm diameter fully threaded locking screws from the T2 Nail System. The device provides mechanical stabilization of bone fractures to facilitate healing.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Intramedullary fixation rod; material: titanium alloy; design: proximal diameter and distal screw hole configuration modifications; compatible with 5 mm diameter fully threaded locking screws; mechanical fixation device.

Indications for Use

Indicated for patients with intertrochanteric fractures of the proximal femur requiring stabilization via intramedullary fixation.

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.

This Special 510(k) submission is intended to address a material modification and design modifications to the predicate Trochanteric Gamma® Nail System. The subject device, named the Trochanteric Dyax Nail System, is a line extension of the Trochanteric Gamma® Nail System. The predicate Trochanteric Gamma® Nail System is fabricated from stainless steel. The subject Trochanteric Dyax Nail System is fabricated from titanium alloy. The design change for the nail involves changing the proximal diameter and changing the distal screw hole diameter and configuration. The 5 mm diameter fully threaded locking screws from the T2 Nail System will be compatible with the Trochanteric Dyax Nail.

The predicate Trochanteric Gamma® Nails an intramedullary rod intended to be used for stabilizing various types of intertrochanteric fractures of the proximal femur. There is no change in intended use for the modified device when compared to the previously cleared product. The subject Trochanteric Dyax Nails are substantially equivalent to the existing design of Trochanteric Gammas Nails which were determined substantially equivalent via the 510(k) process.

Dear Ms. Ariemma:

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 (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. 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 (PMA), it may be subject to such 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.
