## Intended Use

Internal fixation devices to aid the surgeon in the stabilization of oral craniomaxillofacial skeletal bone, small bones of the hand, feet, wrist, ankles, fingers and toes, for the fixation of fractures, osteotomies, revision procedures, joint fusion and reconstructive procedures.

## Device Story

Rapidfire Self Drilling Screws are metallic bone fixation fasteners; 1.5 mm to 2.0 mm diameter; thread lengths up to 7 mm; center or cross drive head. Designed for self-drilling into bone without mandatory predrilling. System includes disposable cartridge containing five screws and disposable screwdriver blades. Used by surgeons in clinical settings for stabilization of craniomaxillofacial and small extremity bones. Cartridges delivered sterile; loaded into driver system for patient application. Provides mechanical fixation to support bone healing in fractures, osteotomies, and reconstructive procedures.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

Metallic bone fixation screws; 1.5-2.0 mm diameter; up to 7 mm thread length; center or cross drive head; self-drilling design; sterile, single-use disposable cartridge system.

## Regulatory 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.

## Predicate Devices

- Lorenz Self Drilling Screws ([K013954](/device/K013954.md))

## Summary of Safety and Effectiveness

| Device Name:         | Lorenz Self Drilling Screw |
|----------------------|----------------------------|
| Classification Name: | Screw, Fixation, Bone      |
| Device Product Code: | 87HWC (21 CFR 888.3040)    |

### Intended Use:

Internal fixation devices to aid the surgeon in the stabilization of oral craniomaxillofacial skeletal bone, small bones of the hand, feet, wrist, ankles, fingers and toes, for the fixation of fractures, osteotomies, revision procedures, joint fusion and reconstructive procedures.

### Description:

The self drilling screws are 1.5 mm to 2.0 mm in diameter and the thread lengths may range up to 7mm. The head may be center drive or cross drive. The screw is designed so that a predrilled hole is not required, but may be used. Five screws are placed within a disposable cartridge A disposable screwdriver blade is loaded between each screw. The cartridges are delivered to the user sterile. The cartridge is loaded into a driver blade system for delivery to the patient.

### Sterility Information:

The Rapidfire Self Drilling Screws will be marketed as sterile, single use devices.

### Substantial Equivalence:

Walter Lorenz considers the Rapidfire Self Drilling Screws equivalent to Lorenz Self Drilling Screws (K013954).

### Possible risks:

- 1. Poor bone formation, Osteoporosis, Osteomyelitis, inhibited revascularization, or infection can cause loosening of the device.
- 2. Nonunion or delayed union which may lead to breakage of the implant.
- 3. Migration, bending, fracture or loosening of the implant
- 4. Metal sensitivity, or allergic reaction to a foreign body.
- 5. Decrease in bone density due to stress shielding.
- 6. Pain, discomfort, abnormal sensation, or palpability due to the presence of the device.
- 7. Increased fibrous tissue response around the fracture site and/or the implant.
- 8. Necrosis of bone.

{1}------------------------------------------------

9. Inadequate healing.

Dear Ms. Reed:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good many:facturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
