Device Facts

• Record ID: K111447
• Device Name: ZIMMER PERIARTICULAR SCREWS
• Applicant: Zimmer, Inc.
• Product Code: HWC · Orthopedic
• Decision Date: Oct 5, 2011
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3040
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Temporary internal fixation devices are designed to stabilize fractures during the normal healing process.

Device Story

Zimmer Periarticular Plating System - Screws are metallic bone fixation fasteners used for temporary internal fracture stabilization. These devices are implanted by surgeons in a clinical setting to provide mechanical support during bone healing. The system consists of screws that function as fasteners to secure plates to bone. The primary modification in this submission is the provision of the screws in a sterile state, whereas previous versions were non-sterile. The device is used to maintain fracture alignment, potentially improving patient outcomes by facilitating stable bone union. The system is intended for prescription use only.

Clinical Evidence

No clinical data was required or provided for this device. Substantial equivalence was demonstrated through non-clinical bench testing, including sterilization validation (gamma dose 20kGy), shelf-life testing (10-year accelerated aging), sterile barrier integrity, and biocompatibility testing per ISO 10993-1.

Technological Characteristics

Metallic bone fixation fasteners (screws). Materials tested for biocompatibility per ISO 10993-1. Sterilization via gamma irradiation (minimum 20kGy). Features include varying diameters, partial vs. full threads, and drive head configurations. Designed for temporary internal fixation.

Indications for Use

Indicated for patients requiring stabilization of fractures during the normal healing process.

Regulatory Classification

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.

Performance Data (Nonclinical and/or Clinical):

- . Sterilization Validation - To demonstrate that at a minimum gamma dose of 20kGy the devices can be terminally sterilized to a SAL greater than or equal to 10-6.

# KI11447 (2/2

- . Shelf Life - Accelerated aging showed that the product has a shelf life of 10 years.
- . Sterile Packaging - To withstand normal distribution and storage conditions and maintain the sterile barrier properties throughout the specified product shelf life.
- . Biocompatibility - Biocompatibility testing on the screw material was conducted per ISO 10993-1 and Good Laboratory Practices (21 CFR § 58). All testing passed.

Providing these screws pre-sterilized did not change the intended use or the fundamental scientific technology of any of the devices. Each sterile device uses the same operating principle and incorporates the same basic labeling.

The results of either engineering evaluations and/or nonclinical (lab) performance testing demonstrate that the devices are safe and effective and substantially equivalent to the predicate devices.

Engineering evaluations included any differences between screw diameters, partial thread vs. full threads, starting load, bending or fatigue failure, material strength and the elimination of locking threads on the drive heads. Screw testing/analysis performed included: cross-sectional analysis, fatigue failure, insertion torque and torque to failure.

In summary, the sterile devices described in this submission are substantially equivalent to their predicates.

Clinical Performance and Conclusions:

Clinical data and conclusions were not needed for this device.
