Intended Use

The AOS Trochanteric Nail is intended to treat stable and unstable proximal fractures of the femur including pertrochanteric, intertrochanteric and high subtrochanteric fractures and combinations of these fractures. The long trochanteric nail is additionally indicated for subtrochanteric fractures, pertrochanteric fractures associated with shaft fractures, pathologic fractures (including prophylactic use) in osteoporotic bone of the trochanteric and diaphyseal areas, long subtrochanteric fracture, ipsilateral femoral fractures, proximal and distal non-unions and malunions and revisions procedures.

Device Story

AOS Trochanteric Nail System components (Solid Locking and Telescoping Lag Screws) used for internal fixation of femoral fractures. Screws lock to intramedullary nail; telescoping design allows thread collapse within barrel. Used in clinical/surgical settings by orthopedic surgeons. Provides mechanical stabilization of bone fractures to facilitate healing. Benefits include fracture reduction and stabilization in osteoporotic or complex fracture scenarios.

Clinical Evidence

Bench testing only. Static and fatigue testing performed per ASTM F384. Torque testing performed per ASTM F543.

Technological Characteristics

Metallic orthopedic fracture fixation screws. Materials and design consistent with predicate systems. Testing conducted per ASTM F384 (static/fatigue) and ASTM F543 (torque).

Indications for Use

Indicated for patients with stable/unstable proximal femoral fractures, including pertrochanteric, intertrochanteric, high subtrochanteric, and combinations thereof. Long nail indicated for subtrochanteric fractures, pertrochanteric fractures with shaft fractures, pathologic fractures (including prophylactic use) in osteoporotic bone, long subtrochanteric fractures, ipsilateral femoral fractures, proximal/distal non-unions, malunions, and revision procedures.

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.

Both AOS screws can be locked to the nail. The Telescoping Lag Screw allows the threads to collapse within the barrel. INDICATIONS FOR USE: The AOS Trochanteric Nail is intended to treat stable and unstable proximal fractures of the femur including pertrochanteric, intertrochanteric and high subtrochanteric fractures and combinations of these fractures. The long trochanteric nail is additionally indicated for subtrochanteric fractures, pertrochanteric fractures associated with shaft fractures, pathologic fractures (including prophylactic

#### SUBSTANTIAL EQUIVALENCE: Information presented supports substantial equivalence of the AOS Solid Locking and Telescoping Lag Screws to the predicate devices. The proposed systems have the same indications for use, are similar in shape and design, have the same fundamental technology and are made of the same material.

PRECLINICAL TESTING: The AOS Solid Locking and Telescoping Lag Screws were each subjected to static and fatigue testing in accordance with ASTM F384, Standard Specifications and Test Methods for Metallic Angled Orthopedic Fracture Fixation Devices. The results demonstrate that the Solid Locking and Telescoping Lag Screws are substantially equivalent to the predicate devices. Additionally, the Telescoping Lag Screw was subjected to torque testing in accordance with ASTM F543, Standard Specifications and Test Methods for Metallic Medical Bone Screws.

#### Dear Ms. Glendrange:

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 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). You may, therefore, market the device, subject to the general controls provisions of the Act. However, you are responsible to determine that the medical devices you use as components in the [kit/tray] have either been determined as substantially equivalent under the premarket notification process (Section 510(k) of the act), or were legally on the market prior to May 28, 1976, the enactment date of the Medical Device Amendments. Please note: If you purchase your device components in bulk (i.e., unfinished) and further process (e.g., sterilize) you must submit a new 510(k) before including these components in your kit/tray. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, and labeling, and prohibitions against misbranding and adulteration.
