• Applicant: Avanta Orthopaedics, Inc.
• Product Code: JDW · Orthopedic
• Decision Date: Jul 17, 1998
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3040
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The intended use of the external fixation device is the same as that expressed in the predicate device 510k. The intended use of the external fixator is unilateral external fixation, device which is intended for use in the treatment of bone conditions including limb lengthening, osteotomies, arthrodesis, fracture fixation and other bone conditions amenable to treatment by use of the external fixation modality.

Device Story

External fixator system comprising frames, bars, pin clamps, pins, and instruments; used for unilateral external fixation. System couples to bone via pins secured by clamps; allows for compression or distraction of bone segments. Operated by clinicians in orthopedic settings to treat fractures, limb length discrepancies, and other bone pathologies. Provides mechanical stabilization to facilitate bone healing or correction.

Clinical Evidence

bench testing only

Technological Characteristics

Metallic bone fixation system; includes frames, bars, pin clamps, and pins. Pin lengths range from 50-90 mm. Mechanical design allows for compression and distraction. No software or electronic components.

Indications for Use

Indicated for patients requiring unilateral external fixation for bone conditions including limb lengthening, osteotomies, arthrodesis, fracture fixation, and other conditions amenable to external fixation.

Regulatory Classification

Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.
