Intended Use

The subject ESL Marathon" Polyethylene Liners are intended to be used with the DePuy Pinnacle® metal acetabular shells, modular femoral heads, unipolar femoral heads, and selfcentering heads to resurface the acetabular socket in cementless total hip arthroplasty. The subject Ultima" " Unipolar and the Sclf-Centering" Hip Prosthesis, originally cleared for hemi-arthroplasty procedures, are also intended for use in total hip replacement when used in conjunction with a metal backed UHMWPE bearing surface having an inside diameter corresponding to the outside diameter of the metallic head/cup that is utilized. The Pinnacle" Enhanced Stability Liner is indicated for use in total hip replacement procedures. Total hip arthroplasty 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. Total hip replacement is indicated in the following conditions: - 1. A severely painful and/or disabled joint from osteoarthritis, traumatic arthritis, theumatoid arthritis, or congenital hip dysplasia. - 2. Avascular necrosis of the femoral head. - 3. Acute traumatic fracture of the femoral head or neck. - 4. Failed previous hip surgery including joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or total hip replacement. - 5. Certain cases of ankylosis. The Pinnacle" ESL is indicated for use with the Pinnacle" Acetabular Cup in cementless application. Self-Centering™ Hip Prostheses and unipolar femoral heads are also intended to be used for total hip arthroplasty 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, when used in conjunction with a UHMWPE bearing surface having an inside diameter corresponding to outside diameter of the metallic cup that is utilized. Use in total hip replacement is indicated in the following additional conditions: 1. A severely painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia 2. Failed previous hip surgery including joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty ,or total hip replacement.

Device Description

The Pinnacle® Acetabular System is part of a modular system designed to replace the natural articular surface of the hip joint in total hip replacement. The acetabular component is provided as two separate units, a porous coated hemispherical outer shell manufactured from titanium alloy (Ti-6Al-4V) and a liner manufactured from cross-linked ultra high molecular weight polyethylene (UHMWPE), which locks into the outer shell. The liner component articulates with a femoral head of an appropriate diameter. The subject Pinnacle® Enhanced Stability (ESL) Marathon™ liners are cross-linked UHMWPE acetabular cup liners that are available in a lateralized neutral, or lateralized face-changing orientation. The liners have inner diameters (ID) intended for use with modular, unipolar, or self-centering (bipolar) femoral heads within the 28mm-48mm size range. The outer diameters geometrically the same as other Pinnacle Acetabular Cup Liners, in a 44mm-76mm size ra offering. There is an addition of a Charnley-style bore on sizes 36mm-48mm ID to increase stability. The Ultima" Unipolar femoral head is provided in a size range of 38mm to 63mm OD, in Imm increments. The subject heads have a tapered bore which can receive a variety of adapter sleeves, originally cleared in K965156 (01-24-07) which are machined from CoCrMo alloy in wrought bar. The femoral head is also used in total hip arthroplasty when used in conjunction with a UHMWPE bearing surface having an inside diameter corresponding to the outside diameter of the modular femoral head that is utilized. The Self-Centering " Hip Prosthesis is a component consisting of a metallic cup and an UHMWPE insert and plastic retaining ring. It is used with a DePuy femoral hip stem and modular metal ball with a head diameter corresponding to the inside diameter of the Self-Centering " Hip polyethylene insert (22mm - 28mm), to replace the femoral head and neck. The Self-Centering Hips are provided in a size range of 39mm through 57mm OD, in 2 mm increments. The bearing inserts are offered in two inner diameters, to accept 22mm and 28mm femoral components. The Self-Centering Hip is being submitted as part of a Total Hip Prosthesis when used in conjunction with a UHMWPE bearing surface having an inside diameter corresponding to the outside diameter of the metallic cup that is utilized.

AI/ML (Artificial Intelligence / Machine Learning)

No
The device description focuses on the materials and mechanical design of hip replacement components (liners, femoral heads, acetabular shells). There is no mention of software, algorithms, data processing, or any terms related to AI/ML.

Therapeutic

Yes
The device explicitly states its intended use is to "provide increased patient mobility and reduce pain by replacing the damaged hip joint articulation," which aligns with the definition of a therapeutic device.

Diagnostic

The device description indicates that these are components for hip replacement surgery (e.g., liners, femoral heads), which are implantable medical devices used to restore joint function rather than to diagnose conditions.

SaMD (Software as a Medical Device)

The device description clearly details physical components made of titanium alloy and UHMWPE, indicating it is a hardware device for hip replacement.

IVD (In Vitro Diagnostic)

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

Intended Use: The intended use clearly describes the device as being used in vivo (within the body) for surgical procedures to replace damaged hip joints. IVDs are used in vitro (outside the body) to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
Device Description: The description details physical components like acetabular shells, liners, and femoral heads, which are implants used in surgery. This is consistent with a surgical device, not an IVD.
Anatomical Site: The anatomical site is the hip joint, which is an internal part of the body. IVDs typically analyze samples like blood, urine, or tissue outside the body.

The information provided strongly indicates that this device is a surgical implant for total hip arthroplasty, not an in vitro diagnostic device.

Regulation Number and Section

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.

(a)
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.(b)
Classification. Class II.
