• Attributes: Therapeutic

Intended Use

Pins, when used in conjunction with the DePuy ACE Trippi-Wells Tong, DePuy ACE Standard Tong, DePuy ACE Universal Tong, or Open and Closed Back Halo Rings, may be used for stabilization of the cervical spine in stationary and mobile traction following: - Cervical fractures - Ligamentous injury of the cervical spine - Fusion or other surgery of the cervical spine

Device Story

Skull pins (Ring Skull Pin, Spring Loaded Tong Pin, Fixed Tip Tong Pin) function as invasive components of cervical traction devices (Halo rings or Tongs). Pins feature zirconia insert between body and tip to prevent electrical current conduction, mitigating risk of burning sensation at insertion sites during MRI. Used in clinical settings for cervical spine stabilization; operated by physicians. Output is mechanical fixation of cervical spine. Benefits include patient safety during MRI procedures by preventing thermal injury.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

Metallic bone fixation pins featuring a zirconia insert between the pin body and tip. Designed for use with halo rings or tongs. Non-conductive insert prevents electrical current passage.

Indications for Use

Indicated for patients requiring cervical spine stabilization in stationary or mobile traction due to cervical fractures, ligamentous injury, or post-surgical fusion/intervention.

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.

Predicate Devices

• DePuy ACE Standard Skull Pin (preamendment)
• DePuy ACE Spring Loaded (Trippi-Wells) Skull Pin (K810193A)

SUBSTANTIALLY EQUIVALENT DEVICE:

DePuy ACE Standard Skull Pin DePuy ACE Spring Loaded (Trippi-Wells) Skull Pin DePuy ACE Fixed Tip Tong

## INTENDED USE:

Pins, when used in conjunction with the DePuy ACE Trippi-Wells Tong, DePuy ACE Standard Tong, DePuy ACE Universal Tong, or Open and Closed Back Halo Rings, may be used for stabilization of the cervical spine in stationary and mobile traction following:

- 트 Cervical fractures
- Ligamentous injury of the cervical spine
- 이 Fusion or other surgery of the cervical spine

## DEVICE DESCRIPTION AND SUBSTANTIAL EQUIVALENCE RATIONALES:

The skull pins, which pass through the halo ring or tong, are the only invasive component of the DePuy ACE cervical traction device. The new skull pins, ring and tong (fixed tip and spring loaded), now include a zirconia insert between the pin body and the pin tip. The zirconia insert eliminates the possibility of an electrical current passing to the patient which may cause a burning sensation at the pin insertion points.

The DePuy ACE Ring Skull Pin - MRJ is similar in design and indications for use to the DePuy ACE Standard Skull Pin, a preamendment device. The DePuy ACE Spring Loaded Tong Pin - MRI and the DePuy ACE Fixed Tip Tong Pin - MRI are similar in design and indications for use to the DePuy ACE Spring Loaded (Trippi-Wells) Skull Pin, which received approval under 510(k) K810193A.

Based on the above information, DePuy ACE Medical Company firmly believes that the new skull pins are substantially equivalent to the previously approved versions.
