Indications for Use
The PINNACLE Dual Mobility Metal Liners are designed to provide additional stability where there is an unstable joint and are for use in total hip arthroplasty which is intended to provide increased patient mobility and reduce pain by replacing the damaged hip joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components. The PINNACLE Dual Mobility Metal Liners are intended for single use only.
Device Story
DePuy PINNACLE Dual Mobility Liner is a cobalt-chrome-molybdenum alloy implant for total hip arthroplasty. Device functions as a modular dual-articulation construct; it features a taper-locking mechanism for assembly into PINNACLE Acetabular Shells. The inner surface articulates with a UHMWPE mobile bearing head. Used by orthopedic surgeons in clinical settings to replace damaged hip joint articulations; provides increased stability for patients with dislocation risks or failed prior surgeries. Benefits include improved joint stability and reduced pain. Device is provided sterile via gamma irradiation.
Clinical Evidence
No clinical tests were conducted. Substantial equivalence is supported by non-clinical bench testing, including range of motion (ISO 21535:2007/AMD 2016), product compatibility verification, standard walking wear testing, jump distance assessment, mechanical testing (partial compliance with ASTM F1820), taper performance testing, and bacterial endotoxin testing (ANSI/AAMI ST72:2011).
Technological Characteristics
Material: Cobalt-chrome-molybdenum alloy. Design: Modular dual articulation. Compatibility: Porous Ti6Al4V shells (48mm–72mm), UHMWPE mobile bearing heads (22.2mm and 28mm IDs). Sterilization: Gamma. Shelf life: 10 years. Packaging: Double PETG blister with Tyvek lid. Standards: ISO 21535:2007, ASTM F1820 (partial), ANSI/AAMI ST72:2011.
Indications for Use
Indicated for patients requiring total hip replacement due to severely painful/disabled joints (typically non-inflammatory degenerative joint disease), failed previous hip surgery, or dislocation risks. Intended for cementless applications.
Regulatory Classification
Identification
A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across the joint. This generic type of device has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.

Dear Melissa Cook:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's
{1}------------------------------------------------
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
