Intended Use

The Fixion"M Intramedullary Nailing System ("Fixion" Nail") is intended for use in the fixation of long bone fractures, including diaphyseal fractures in the humerus, femur and the tibia. It is indicated for use in shaft fractures 5cm below the surgical neck to 5cm proximal to the distal end of the medullary canal.

Device Story

Fixion Intramedullary Nailing System; single-use orthopedic implant for long bone fracture fixation. System components: expandable stainless steel nail, driver, and manual inflation pump. Surgeon inserts nail into medullary canal; uses driver to connect inflation device. Inflation device pumps sterile liquid into nail, expanding diameter to contact canal walls; expansion monitored via X-ray. Provides mechanical fixation equivalent to locking nails. Used in clinical settings by orthopedic surgeons. Benefits: secure fixation via expansion against medullary wall.

Clinical Evidence

Evidence includes in-vitro mechanical testing and animal studies. Mechanical testing performed per ASTM F1264 (4-point bending) and ASTM F383 (torsion). No human clinical trial data provided.

Technological Characteristics

Expandable non-slotted cylindrical stainless steel 316L nail (ASTM F138). Features reinforcement bars for structural integrity. Driver and manual inflation pump system. Mechanical expansion principle using sterile fluid. Dimensions/form factor: intramedullary rod. Sterilization: single-use.

Indications for Use

Indicated for fixation of long bone fractures, including diaphyseal fractures of the humerus, femur, and tibia, specifically shaft fractures located 5cm below the surgical neck to 5cm proximal to the distal end of the medullary canal.

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.

## Predicate Devices

- · CINTOR Orthopedic Div's Aginsky Nail (K803106
- · HOWMEDICA's Seidel Humeral Locking Nail (K883882, K924004, K925544, K931256)
- SYNTHES's AO Universal Tibial and Femoral Nails (K914453, and K914371
- · SYNTHES's AO Unreamed Humeral (UHN) Tibial (TNN) and Femoral (UFN) Nails (K933518, K932330, and K923580, respectively).

### Performance Standards

No performance standards applicable to Intramedullary Nails have been established by the FDA. However, the following standards were used:

- · Stainless steel 316L which is used to manufacture the Fixion™ Intramedullary Nailing System meets the requirements of ASTM F138 - Standard Specification for Stainless steel Bar and Wire for Surgical Implants.
- · The 4 point bending mechanical testing was performed according to ASTM F 1264 - standard for mechanical performance considerations for intramedullary fixation devices.
- · The torsional mechanical testing was performed according to ASTM F383 -Standard Practice for Static Bend and Torsion Testing of Intramedullary Rods.

### Intended Use

The Fixion"M Intramedullary Nailing System ("Fixion" Nail") is intended for use in the fixation of long bone fractures, including diaphyseal fractures in the humerus, femur and the tibia. It is indicated for use in shaft fractures 5cm below the surgical neck to 5cm proximal to the distal end of the medullary canal.

{2}------------------------------------------------

## System Description

The Fixion™ Intramedullary Nailing System is a single use system that features 3 main components: Nail implant, Driver, and Inflation device.

- · The Nail implant is an expandable non-slotted stainless steel cylindrical tube, with a conical shaped distal end and a cap protected, female threaded proximal end.
- · The Driver is a stainless steel cylinder with plastic handle. used for the nail insertion, location and adjustment at the intramedullary canal. In addition, it serves as a delivery system for the inflation liquid.

The Driver has a male threaded end to be connected to the Nail implant proximal end. A quick connector is located on the Driver to be connected to the Inflation device.

- · The Inflation device is a single use manual plastic "pump", filled with sterile inflation liquid, similar to a PTCA inflation pump but with higher pressure. The inflation device outlet pipe end has a female quick connector to be connected to the Driver connector.
Once the nail is positioned within the medullary canal, rotation of the "pump" handle allows for nail diameter increase to its intended diameter under X-ray and controlled pressure.

### Substantial Equivalence

The Fixion™ Nail has the same intended use and substantially similar indications for use as the predicates, i.e., fixation of long bone fractures of the humerus, tibia, and femur.

The performance characteristics of the Fixion Nail have been tested and approved through a series of in-vitro and animal studies.

The Fixion™ Nail, like the Synthes Universal Tibial and Femoral Nails, is a Stainless Steel 316L canulated design. The cross section of the Fixion™ Nail is circular with reinforcement bars, which was found to be equivalent in mechanical properties to the circular cross section of the predicate devices.

With respect to fixation, the expansion of the Fixion™ Nail results in the attachment of the 4 reinforcement bars to the medullary canal wall, providing equivalent fixation to the distal mechanism of the Seidel Humeral locking nail, in which the nail distal end's three leaves are expanded and attached to the medullar canal wall.

The expansion of the Fixion nail with saline, which is a non-compressible biocompatible fluid, does not raise any safety concerns.
