#### Device Description:

The OsteoBridge™ IDSF - Intramedullary Diaphyseal Segmental Defect Fixation Rod System is a series of modular intramedullary rod segments that may be used as either proximal or distal segments. The segments are designed to be attached together to form a complete intramedullary rod using semicircular hollow attachment shells that are clamped together with multiple screws to create a complete intramedullary rod. The complete unit is designed to accept interlocking bone screws for additional rotational stability.

The implants from this submission are an extension of the OsteoBridge™ IDSF - Intramedullary Diaphyseal Segmental Defect Fixation Rod System (K051965/K113303). The components from this submission can be used in combination with the rod segments from the OsteoBridge™ IDSF diameter 10 to 16 mm (K051965) as well as with the dia. 5 mm interlocking screws. In addition sterile intramedullary rod segments are available in diameters of 18 mm

{4}------------------------------------------------

and 20 mm in lengths of 90 mm and 110 mm. The hollow central attachment shell for use in the femur has a diameter of 34 mm and is available in four lengths 40 mm, 50 mm, 60 mm and 70 mm with reducing bushings to allow the use of different diameter rods proximally and distally to better fit the medullary canal. If the defect size is larger than 70 mm, two attachment shells can be connected by a spacer connector.

All components of the OsteoBridge™ IDSF system are manufactured from Ti-6Al-4V titanium alloy conforming to ASTM F 136-13.

#### Indications for Use

The device is intended to be used in the management of segmental diaphyseal bone loss of the femur in oncology patients secondary to radical bone loss and/or resection due to tumors. The intramedullary rods can be fixed with interlocking screws without or with bone cement.

## Substantial Equivalence:

The OsteoBridge™ IDSF System is technologically equivalent to the predicate devices.

## Legally marketed Devices to which substantial Equivalence is claimed

K051965 - OsteoBridge™ IDSF Intramedullary Diaphyseal Segmental Defect Fixation System

K113303 - OsteoBridge™ IDSF Intramedullary Diaphyseal Segmental Defect Fixation System

#### Non-Clinical Performance Data:

In order to demonstrate that the OsteoBridge™ IDSF has the mechanical properties necessary to perform its intended use, and that the device performs as well as or better than the predicate device. Merete has conducted mechanical and functional testing (according to ASTM F-1264-03). The tests represent the worst case scenario for the strength of the system. All products have successfully passed all tests. The OsteoBridge™ IDSF system has hereby been proven to be mechanically safe.
