Intended Use

The Ceramic Tipped Skull Pins are intended for use in conjunction with the Jerome Halo System that provides cervical immobilization and/or traction for healing and rehabilitation of cervical spinal cord injuries.

Device Story

Ceramic Tipped Skull Pins are invasive components of Halo Traction Systems; used to immobilize cervical vertebrae following surgery or injury. Device consists of a threaded pin with a ceramic tip; designed to hold the skull firmly relative to the torso. Ceramic tip provides electrical non-conductivity; reduces risk of electric current passage to patient, preventing burning sensations at insertion points and imaging artifacts. Operated by physicians in clinical settings. Output is mechanical fixation of the skull. Benefits include improved patient safety during imaging and reduced risk of electrical injury compared to conductive metallic pins.

Clinical Evidence

No clinical data. Bench testing only. Both Ceramic Tipped Skull Pins and Titanium Skull Pins were tested for mechanical integrity per ASTM F 1831-97, section 11. Both designs met the standard requirements.

Technological Characteristics

Materials: Ti6Al4V Titanium, ZrO-ATP BIO-HIP Ceramic, Epoxy. Threaded pin design. Non-conductive electrical safety profile. Compatible with X-ray, CT, and MR imaging. Sterilization: EtO. Mechanical performance meets ASTM F 1831-97.

Indications for Use

Indicated for patients requiring cervical immobilization and/or traction following surgery or injury to the cervical spine, used as part of a Halo Traction System to hold the skull firmly in place relative to the torso.

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.

510(k) Summary As required by section 807.92(c)

Trade Name: Ceramic Tipped Skull Pins

Common Name: Traction Skull Pins

Classification Name: Single/multiple component metallic bone fixation appliances and accessories Sec. 888.3030 Class II LXT

Substantially Equivalent to: Jerome Traction Skull Pins (included in K822780 and K930153) also manufactured by Jerome Medical. Also similar to Traction Skull Pins included in Bremer Halo System Cervical Traction Skull Pin (K915800, K810193), DePuy Ace Skull Pin and Tong Pin (K974245) Friddle Halo System (K980689), and PMT Halo Systems. Copies of representative product literature are included in Competition (Tab 10).

Description: The Ceramic Tipped Skull Pins are similar to other skull pins which, when used as part of a Halo Traction System, are designed to hold the skull firmly in place relative to the torso so cervical vertebrae are immobilized following surgery or injury. They are the only invasive components of the Systems. The new Skull Pins include a ceramic tip. The ceramic tip reduces the possibility of an electric current passing to the patient. Such current may cause imaging artifact and/or a burning sensation at the pin insertion points. Engineering drawings of Ceramic Tipped Skull Pin assemblies are included in Device Name & Description, Tab 2.

The Ceramic Tipped Skull Pins are substantially equivalent to Skull Pins. Differences are the use of non-conductive materials for improved image quality and patient safety; and thicker material (Halo Skull Pin: 0.3125 inch major diameter Ceramic Tipped Skull Pin vs. 0.250 inch Titanium Skull Pin) for offset load strength. Both clinical and laboratory tests confirm that the new material and design meet the same standard for mechanical integrity as the predicate device.

Laboratory Tests: Both the Ceramic Tipped Skull Pins and Generation 80 (Titanium) Skull Pins were tested to the standard of ASTM F 1831-97, section 11. Both met the standard. A test summary is at page 5-1. The material and design changes do not adversely affect product performance.

Intended Use: The Ceramic Tipped Skull Pins are intended for use in conjunction with the Jerome Halo System that provides cervical immobilization and/or traction for healing and rehabilitation of cervical spinal cord injuries.

Conclusions: The Ceramic Tipped Skull Pins are similar to previously approved Skull Pins in function and indications for use. The devices are substantially equivalent.
