## Intended Use

The Titanium Ankle Arthrodesis Nail is intended for tibiotalocalcaneal arthrodesis (fusion). The process of tibiotalocalcaneal arthrodesis using an intramedullary nail usually involves an ankle arthrotomy, preparation of the joint surfaces, and then placement of the nail through a plantar incision. Screws are placed proximally into the tibia in a standard fashion and, after compression, the nail can be locked distally with screws into the calcaneus and the talus.

## Device Story

Titanium alloy intramedullary nail; used for tibiotalocalcaneal arthrodesis. Device inserted through plantar incision into medullary canal of tibia; stabilizes bone fragments to facilitate fusion. Transverse screws provide proximal and distal locking into tibia, calcaneus, and talus. Used in surgical setting by orthopedic surgeons. Provides mechanical fixation to maintain alignment during bone healing. Benefits include stabilization of complex ankle/hindfoot deformities or post-traumatic conditions.

## Clinical Evidence

Bench testing only. No clinical data provided. Substantial equivalence based on design, material, and intended use similarity to predicate devices.

## Technological Characteristics

Tubular intramedullary rod; titanium alloy construction. Diameters: 10, 11, 12 mm; lengths: 15 cm, 18 cm, up to 46 cm. Mechanical fixation via transverse locking screws. Standalone device; non-powered.

## Regulatory 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

- Biomet Titanium Intramedullary Nails ([K982953](/device/K982953.md))

## Summary of Safety and Effectiveness Titanium Ankle Arthrodesis Nail

Applicant/Sponsor: Biomet Orthopedics, Inc. P.O. Box 587 Warsaw, Indiana 46581-0587

- Contact Person: Lonnie Witham Telephone: (574) 267-6639 Fax: (574) 372-1683
Proprietary Name: Titanium Ankle Arthrodesis Nail

Common Name: Titanium Intramedullary Nail (Rod)

Classification Name: Intramedullary Rods (21 CFR 888.3020)

Legally Marketed Devices to Which Substantial Equivalence Is Claimed: These devices are substantially equivalent to Biomet Titanium Intramedullary Nails previously cleared in K982953.

- Device Description: Intramedullary rods made of titanium alloy are used for the same indications as stainless steel intramedullary rods that have been commercially available continually since the 1950s. These devices are to be implanted by insertion into the long bones for fixation of fractures, or the fixation of long bones that have been surgically prepared (osteotomy) for correction of deformity, or arthrodesis. Transverse screws can be used to further stabilize bone fragments distally and proximally, as needed. A wide variety of titanium intramedullary nails indicated for used in long bones (femur, tibia, fibula, humerus, radius, and ulna were cleared for commercial distribution in Biomet 510(k) premarket notification (K982953).
These ankle arthrodesis nails have the same general intended use (arthrodesis, internal fixation of bone), warnings and precautions as those nails previously cleared in K982953. The standard arthrodesis nails are10, 11, and 12 mm in diameter in 15 mm and 18 cm lengths. Longer lengths will be made upon request (up to 46 cm length). The longer nails will be used to treat patients who may require revision of a previously implanted arthrodesis nail due to tibial fracture. Substantially similar titanium femoral and tibial nails in 8, 9, 10, 11, 12, 13 and 14 mm diameters up to 46 cm in length were previously cleared in K982953.

Screws are placed proximally into the tibia in a standard fashion and, after compression, the nail can be locked distally with screws into the calcaneus and the talus.

# Indications for Use

### The indications for tibiotalocalcaneal arthrodesis include:

- 1. Avascular necrosis of the talus
- 2. Failed total ankle arthroplasty
- 3. Trauma (malunited tibial pilon fracture)
- 4. Severe deformity or instability as a result of talipes equinovarus, cerebral vascular accident, paralysis or other neuromuscular disease
- 5. Revision ankle arthrodesis
- 6. Neuroarthropathy
- 7. Rheumatoid arthritis
- 8. Osteoarthritis
- 9. Pseudoarthrosis

Summary of Technology: This device utilizes standard technology that is commonly known by physicians. This technology has been used in commercially available metallic internal fixation devices prior to May 28, 1976. This particular device is a tubular metal rod that is inserted through the talus and into the medullary canal of the tibia to stabilize bone fragments until healing has occurred.
