Intended Use

The Zimmer Natural Nail System is intended for temporary fracture fixation and stabilization of the bone. Indications for use of the retrograde femoral nails in the femur include: Compound and simple shaft fractures Proximal, metaphyseal, and distal shaft fractures Segmental fractures Closed supracondylar fractures Severely comminuted supracondylar fractures with articular involvement Fractures involving femoral condyles Comminuted fractures Fractures involving osteopenic and osteoporotic bone Pathological fractures Fractures with bone loss Pseudoarthrosis, non-union, and mal-union Periprosthetic fractures Poly trauma patients

Device Story

The Zimmer Natural Nail System Retrograde Femoral Nails are temporary intramedullary fixation rods used for femoral fracture stabilization. The system consists of nails, screws, nail caps, cortical washers, and cortical nuts. The device is inserted into the femur in a retrograde mode; screws are passed through proximal and distal holes to secure the nail. Used by orthopedic surgeons in a clinical/surgical setting. The device provides mechanical stabilization to facilitate bone healing. Benefits include fixation for various fracture types, including those in compromised bone (osteopenic/osteoporotic).

Clinical Evidence

No clinical data was required or provided for this device. Substantial equivalence was demonstrated through non-clinical bench testing, including proximal and distal nail fatigue tests, midshaft analysis, torsional stiffness analysis, screw bending fatigue, insertion load/torque tests, and shelf-life testing of UHMWPE components.

Technological Characteristics

Intramedullary fixation rod system. Materials: Ti-6Al-4V alloy; UHMWPE (cortical nut). Design: Retrograde femoral nail with proximal/distal screw fixation. Mechanical stabilization principle. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring temporary fracture fixation and stabilization of the femur, including compound/simple shaft, proximal/metaphyseal/distal shaft, segmental, closed/comminuted supracondylar, condylar, pathological, and periprosthetic fractures, as well as fractures with bone loss, pseudoarthrosis, non-union, mal-union, and poly trauma. Suitable for use in osteopenic and osteoporotic bone.

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.

Zimmer® Natural Nail™ System Retrograde Femoral Nails

Intramedullary Fixation Rod

Intramedullary fixation rod, product code HSB 21 CFR § 888.3020

Supracondylar Intramedullary Nail, manufactured by Zimmer, Inc. (K962561, cleared September 25, 1996)

DePuy ACE Universal and Troch Entry Femoral Nail Systems, manufactured by DePuy ACE (K033329, cleared November 14, 2003)

The Zimmer Natural Nail System Retrograde Femoral Nails are a family of temporary fixation intramedullary nails designed for fracture fixation and stabilization of the femur. They are inserted into the femur in a retrograde mode and are available in a variety of lengths and diameters to meet assorted anatomical needs. Each of the intramedullary nails is secured by a series of screws that pass through holes manufactured into the proximal and distal sections of each nail. Nail caps, cortical washers and cortical nuts are available for use with the system. All components are

manufactured from Ti-6Al-4V alloy. The cortical nut also contains UHMWPE.

The Zimmer Natural Nail System is intended for temporary fracture fixation and stabilization of the bone.

Indications for use of the retrograde femoral nails in the femur include:

- . Compound and simple shaft fractures
- Proximal, metaphyseal, and distal shaft fractures
- Segmental fractures
- Closed supracondylar fractures ●
- Severely comminuted supracondylar fractures ● with articular involvement
- . Fractures involving femoral condyles
- Comminuted fractures �
- Fractures involving osteopenic and osteoporotic ● bone
- . Pathological fractures
- . Fractures with bone loss
- . Pseudoarthrosis, non-union, and mal-union
- Periprosthetic fractures
