No
The device description and performance studies focus on mechanical properties and equivalence to predicate external fixation systems, with no mention of AI or ML.

Yes
The device is intended for treatment of various indications in the tibia, including fracture fixation, correction of deformity, osteotomy, bone union, bone reconstruction, and leg lengthening, all of which are therapeutic interventions.

No

The device is an external fixation system used for treatment, correction, and reconstruction of bone conditions, not for diagnosing them. Its purpose is mechanical support and stabilization.

No

The device description explicitly states it is an external fixation device consisting of physical components like a fixation plate and pins made of stainless steel and aluminum alloy. It also describes mechanical testing of these physical components. There is no mention of software as a component or function of the device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
  • Device Description: The PK High Tibial Osteotomy Correction System is an external fixation device. It is surgically implanted onto the bone (tibia) to provide structural support and facilitate healing or correction.
  • Intended Use: The intended uses listed (fracture fixation, deformity correction, osteotomy, etc.) are all procedures performed on the patient's body, not on specimens taken from the body.

This device is a surgical implant/external fixation device, not an IVD.

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
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.(b)
Classification. Class II.

Device Description:

The PK High Tibial Osteotomy Correction System is a single-use external fixator which consisting of the following components: fixation plate, cortex pin and cancellous pin. Pins are available in various lengths and diameters according to practical requirements. These pins and other components are manufactured from 316L stainless steel (ASTM F138/ ISO 5832-1) and aluminum alloy. These devices are intended to be used in the tibia. Adjustment of the fixator is possible during the course of treatment. All components are provided sterile.

Intended Use:

The PK High Tibial Osteotomy Correction System is an external fixation device, which is intended for use in the treatment of the following indications in the tibia:

  • Temporary fracture fixation
  • Correction of deformity
  • Osteotomv
  • Bone union
  • Bone reconstruction
  • Fracture fixation and other bone conditions amenable to treatment by use of the external fixation modality
  • Leg lengthening

Technological Characteristics:

The subjective device narrows the application site from limbs to tibial; thus, the indications in joint arthrodesis and pelvic fixation are not included in the subjective device. Also, the pin size of 2 mm and 3 mm is not included in the subjective device due to those specifications are not intended for use in the lower extremity. The subjective device is made of stainless steel (ASTM F138/ ISO 5832-1) and aluminum alloy, which is the same as the predicate devices. In addition, the subjective device simplified the tradition external fixator; the pin holder clamp, articulation coupling and connecting rod has been incorporate as a fixation plate to improve the manipulation and easy for use. The fixation plate of the subjective device is a base intended to hold cortex and cancellous pins through tightening the respective set screws. The frame type of subjective device is termed unilateral, which is similar to the primary and additional predicates. The rotation angle and displacement between proximal and distal plate can be adjusted through manipulation of universal ring on the fixation plate. Therefore, the subjective device provides same function as the predicate devices.

In summary, the subjective device has the same or similar technological characteristics as the predicate devices.

Non-Clinical Performance Data:

Mechanical testing including static/dynamic axial load test, static torsion test, static cantilever bend test, and four-point bend test were conducted referring to ASTM F1541 to demonstrate substantial equivalence to the predicate system. In addition, grip testing was also performed to demonstrate substantial equivalence to the predicate system. The results demonstrate substantial equivalence of the PK High Tibial Osteotomy Correction System to legally marketed external fixation systems and therefore appropriate for use in the aforementioned indications.

Clinical Performance Data:

Clinical testing was not required for this submission.

Conclusion of Substantial Equivalence:

The PK High Tibial Osteotomy Correction System has been demonstrated to be substantially equivalent to predicate system with respect to intended use, material, technical characteristics and performance. The information provided within this premarket notification supports substantial equivalence of the subjective device to the predicate device.
