Device Facts

• Record ID: K020905
• Device Name: NBX - NON-BRIDGING EXTERNAL FIXATOR
• Applicant: Biomet Orthopedics, Inc.
• Product Code: LXT · Orthopedic
• Decision Date: Apr 15, 2002
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 888.3030
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Stabilization of open and/or unstable fractures of the distal radius, where soft tissue injury may preclude the use of other fracture treatments such as IM rodding, casting and other means of external fixation.

Device Story

NBX Non-Bridging External Fixator is a radiolucent polycarbonate device for distal radius fracture stabilization. Non-bridging design allows wrist function during treatment. Device consists of two plates with multiple pin holes; pins are inserted through plates into bone and secured via plate interference. External bracket allows lateral pin insertion for additional fixation. Threaded pin in distal slot enables fracture site distraction. Used by clinicians in orthopedic settings. Output is mechanical stabilization of bone fragments, facilitating healing while maintaining joint mobility.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by mechanical bench testing.

Technological Characteristics

Materials: Radiolucent polycarbonate. Design: Non-bridging external fixator with two-plate interference pin fixation system. Features: Lateral bracket for additional pins, threaded pin slot for distraction. Energy source: None (mechanical). Connectivity: None. Sterilization: Not specified.

Indications for Use

Indicated for patients with open and/or unstable distal radius fractures where soft tissue injury precludes alternative treatments like IM rodding, casting, or other external fixation.

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.

Proprietary Name: NBX - Non-Bridging External Fixator

Common Name: External Fixator

Classification Name: Single/Multiple component metallic bone fixation appliances and accessories (21 CFR 888.3030)

Legally Marketed Device to which Substantial Equivalence is Claimed: Biomet External Wrist Plate (K003240)

Device Description: The device is an external wrist fixator made of radiolucent polymer, polycarbonate. The fixator is a non-bridging device, which means that it does not cross the wrist. A non-bridging device gives patients the ability to utilize wrist function.

The device consists of two plates with multiple pin holes. Pins are inserted through the plates, into the bone and held in place by the interference of the two plates. The plate has an external bracket that allows pins to be inserted from the side for additional fixation. If desired, distraction of the fracture site may be achieved with adjustment of a threaded pin placed within a slot on the distal end of the plate.

Intended Use: Stabilization of open and/or unstable fractures of the distal radius, where soft tissue injury may preclude the use of other fracture treatments such as IM rodding, casting and other means of external fixation.

Summary of Technologies: The technological characteristics (materials, design, sizing and indications) of the NBX – Non-Bridging External Fixator are similar to or identical to the predicate device.

Non-Clinical Testing: Mechanical testing was conducted to insure the design changes would not effect the safety of the device.

Clinical Testing: None provided
