Indications for Use
Noninflammatory degenerative joint disease, including osteoarthritis and avascular necrosis; Rheumatoid arthritis; Correction of functional deformity; Revision procedures where other treatments or devices have failed; and, Nonunions, femoral neck fractures, and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques. Additional indications specific to the Restoration Modular Hip System: The Restoration® Modular Hip System is intended to be used for primary and revision total hip arthroplasty, as well as in the presence of severe proximal bone loss. These femoral stems are designed to be press fit into the proximal femur.
Device Story
Restoration® Modular Hip System is a bowed femoral distal stem used in total hip arthroplasty; designed for press-fit fixation in proximal femur. Device features plasma-sprayed commercially pure titanium coating and PureFix™ hydroxylapatite (HA) coating. Used by orthopedic surgeons in clinical settings for primary or revision hip procedures, particularly in patients with severe proximal bone loss. Device provides structural support for hip joint reconstruction. Modifications include addition of a Thermoplastic Polyurethane (TPU) sleeve to packaging and increased outer carton thickness to ensure sterile barrier integrity during transport.
Clinical Evidence
No clinical data required. Substantial equivalence based on design identity and non-clinical packaging validation.
Technological Characteristics
Bowed femoral distal stem; materials: commercially pure titanium plasma-spray, PureFix™ hydroxylapatite (HA) coating. Dimensions: 11-26 mm diameter, 317 mm length. Packaging: TPU sleeve, cardboard outer carton. Standards: ISO 11607-1, ASTM F1886, ASTM F88, ASTM F1929, ASTM D4169, ANSI/AAMI ST72:2011 (BET).
Indications for Use
Indicated for patients requiring primary or revision total hip arthroplasty due to noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, failed previous treatments, or proximal femur fractures (nonunions, femoral neck, trochanteric) with head involvement. Also indicated for cases with severe proximal bone loss.
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 Nora O'Connor:
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
May 27, 2020

{6}------------------------------------------------
#### Summary of Technological Characteristics
The subject device is identical in intended use, indications for use, product design, product materials, operational principles and sterile barrier materials as the predicate device. The subject device is different from the predicate device in terms of the packaging configuration. A TPU sleeve will be added to the packaging configuration. The thickness of the outer carton will be increased.
### Non-Clinical Testing
There have been no changes made to the device design or device materials. Non-clinical testing was not required as a basis for substantial equivalence.
A ship test study was completed on the subject device to qualify the introduction of the TPU sleeve to the packaging configuration. A compression test was included as part of the ship to qualify the increase in thickness of the outer carton on the subject device. Testing was completed as per ISO 11607-1, ASTM F1886, ASTM F88, ASTM F1929, and ASTM D4169.
Bacterial Endotoxin Testing (BET) as specified in ANSI/AAMI ST72:2011 was used for pyrogenicity testing on the subject device to meet an endotoxin limit of <20 Endotoxin Units (EU)/device.
### Clinical Testing
Clinical testing was not required as a basis for substantial equivalence.
#### Conclusion
The Restoration® Modular Hip System is substantially equivalent in intended use, indications for use, product design, product materials, operational principles and sterile barrier materials to the predicate device. The proposed modifications do not affect safety or effectiveness.
