Intended Use

The BIOFOAM® Bone Wedge is intended to be used for internal bone fixation for bone fractures, fusions, or osteotomies in the ankle and foot, such as: · Cotton and Evans Wedges: · Opening wedge osteotomies of the bones of the foot including osteotomies for Hallux Valgus · Opening wedge of Medial Cuneiform or Cotton osteotomies · Lateral Column Lengthening (Evans Lengthening Osteotomy or Calcaneal Z Osteotomy) Metatarsal/Cuneiform arthrodesis · Midfoot Wedges: · Opening wedge osteotomies of the bones of the foot including osteotomies for Hallux Valgus Nonunion of arthrodesis of the Midfoot including Metatarsal/Cuneiform arthrodesis (TMT or Lapidus) This device is intended for use with ancillary fixation. The BIOFOAM® Bone Wedge is not intended for use in the spine.

Device Story

BIOFOAM® Bone Wedge is a titanium metal foam implant designed for angular correction of small bones in the foot and ankle. It functions as a structural spacer during osteotomies, fusions, or fracture repairs. The device is intended for use in conjunction with ancillary fixation hardware. It is utilized by orthopedic surgeons in clinical settings. By providing a porous titanium scaffold, the wedge supports bone fixation and stabilization, facilitating healing in procedures such as Cotton or Evans osteotomies and midfoot arthrodesis.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing including morphological characterization, abrasion, friction, compression, and fatigue testing, as well as biocompatibility and animal testing.

Technological Characteristics

Titanium metal foam bone wedge. Available in varying widths and thicknesses. Designed for use with ancillary fixation. Manufactured via modified technique compared to predicates.

Indications for Use

Indicated for patients requiring internal bone fixation for fractures, fusions, or osteotomies in the ankle and foot. Specific applications include Hallux Valgus correction, Cotton osteotomies, lateral column lengthening, and midfoot arthrodesis. Not for use in the spine.

Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

Dear Ms. Myles:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
