• Attributes: Therapeutic

Intended Use

The primary indication for these devices is the replacement of segmental defects of long bone, including midshaft replacement, and arthrodesis of the knee. Indications include: 1. Treatment of patients who are not candidates for total knee arthroplasty. 2. Irretrievably failed total knee arthroplasty. 3. Limb salvage in oncology surgery. 4. Trauma. 5. Any other condition where there is little soft tissue or bony tissue available for support, and arthrodesis is the treatment of choice. These devices are intended for cemented use only.

Device Story

Modular Arthrodesis Nail provides rigid fixation for knee arthrodesis and long bone segmental defect replacement. Device consists of femoral and tibial adapter segments connected by a central locking collar. Adapter segments available in two resection lengths (1 cm or 3 cm) and two body styles (standard or elliptical). Used in surgical settings by orthopedic surgeons. Device requires cement for fixation. Provides structural support for patients with failed arthroplasty, trauma, or oncological defects.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench-top mechanical testing.

Technological Characteristics

Multi-component intramedullary fixation rod. Material: Ti-6Al-4V titanium alloy (ASTM F-136). Design: Modular femoral and tibial adapter segments with central locking collar. Resection lengths: 1 cm or 3 cm. Body styles: standard or elliptical. Fixation: Cemented use only.

Indications for Use

Indicated for patients requiring knee arthrodesis or long bone segmental defect replacement (including midshaft) due to failed total knee arthroplasty, oncology-related limb salvage, trauma, or conditions with insufficient soft/bony tissue support. Contraindicated for patients who are candidates for total knee arthroplasty. Intended for cemented use only.

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.

These devices are intended for cemented use only.

Summary of Technologies: The Modular Arthrodesis Nail has the same intended use (arthrodesis), the same functional characteristics (rigid fixation) as the predicate devices, and is made of the same titanium alloy material as the predicate Titanium Intramedullary Nails and Orthopedic Salvage System (OSS) components used with the Modular Arthrodesis Nail.

Non-Clinical Testing: Mechanical testing indicated that the Modular Arthrodesis Nails are substantially equivalent to the predicate devices for the uses indicated.

Clinical Testing: Clinical testing was not required for these components to support substantial equivalence.
