Intended Use

The Delta Acetabular System is indicated for use in total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions: - Non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis and hip dysplasia; - Rheumatoid arthritis; - Post-traumatic arthritis, - Correction of functional deformity; - Fractures, dislocation of the hip and unsuccessful cup arthroplasty; - Revisions in cases of good remaining bone stock; - Revision of previously failed total hip arthroplasty (Delta Multihole TT Pro only). The Delta Acetabular System is intended for cementless use.

Device Story

Acetabular cup system for total hip arthroplasty; used in cementless orthopedic surgery. System components include titanium alloy cup, cross-linked UHMWPE liners with Vitamin E, and modular femoral heads (Biolox Delta ceramic or CoCrMo alloy). Cup features hemispherical design with cranial and caudal holes for fixation screws to enhance stability. Surgeons implant device to replace damaged hip joint surfaces; provides mechanical support and articulation. Benefits include pain reduction and improved hip function. Device is a passive orthopedic implant; no software or electronic components.

Clinical Evidence

No clinical data. Substantial equivalence demonstrated via bench testing, including push-out, lever-out, torque-out (ASTM F1820-13), stiffness (ISO 7206-12:2016), and unsupported anatomical fatigue deformation testing.

Technological Characteristics

Titanium alloy cup; cross-linked UHMWPE with Vitamin E liners; Biolox Delta ceramic or CoCrMo alloy femoral heads. Cementless fixation. Mechanical testing per ASTM F1820-13 and ISO 7206-12:2016. No software or electronic components.

Indications for Use

Indicated for skeletally mature patients undergoing total hip arthroplasty for pain relief or improved function due to osteoarthritis, avascular necrosis, hip dysplasia, rheumatoid arthritis, post-traumatic arthritis, functional deformity, fractures, hip dislocation, failed cup arthroplasty, or revision of failed total hip arthroplasty.

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 Stephen Peoples:

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 requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part

#### Common name:

Acetabular Cup System

#### Description:

The Delta Multihole TT Pro Acetabular System consists of a Delta Multihole TT Pro cup, an acetabular liner and a modular femoral head. Bone screws can also be used to provide additional stability of the cup.

The Delta Multihole TT Pro cup is manufactured from titanium alloy; the Delta Multihole TT Pro liners are manufactured from cross-linked UHMWPE with Vitamin E and the femoral heads made of Biolox Delta ceramic or Cobalt Chrome Molybdenum alloy.

The design of shell is similar to the Delta TT Pro Acetabular System (K182099) and the G7 Acetabular System (Biomet, Inc., K140669) devices. The acetabular liners, the Biolox Delta heads, the CoCrMo heads and the bone screws are the same as those cleared in K182099. The Multihole TT Pro cup has a hemispherical design and provides holes in cranial and caudal aspects of the cup to provide additional cup stability by means of fixation screws. The Multihole TT Pro cup is coupled with a Delta TT Pro acetabular liner that is available in neutral, protruded and high wall versions.

#### Intended Use/Indications:

The Delta Acetabular System is indicated for use in total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions:

- Non-inflammatory degenerative joint disease such as osteoarthritis, avascular ● necrosis and hip dysplasia;
- Rheumatoid arthritis;
- Post-traumatic arthritis, ●
- Correction of functional deformity; ●
