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. ## Device Story Modular acetabular cup liner for total hip replacement; manufactured from cross-linked ultra-high molecular weight polyethylene (UHMWPE). Device locks into titanium alloy (Ti-6Al-4V) hemispherical shell; articulates with metal or ceramic femoral heads (28mm-48mm). Used in orthopedic surgery to replace damaged hip joint surfaces; aims to increase patient mobility and reduce pain. Marketing claim: reduced wear when articulated against ceramic femoral heads compared to cobalt-chromium heads. Device is identical to previously cleared predicate; submission supports updated wear performance claims based on in-vitro hip simulator testing. ## Clinical Evidence Bench testing only. In-vitro hip simulator wear study conducted over 5 million cycles, followed by 2 million cycles with roughened heads. Compared AltrX liners (with ceramic vs. CoCrMo heads) against Enduron control liners. Results showed 3.32 ± 0.38 mg/MC wear rate for AltrX/ceramic group vs. 4.99 ± 0.66 mg/MC for AltrX/CoCrMo group. Note: In-vitro wear results have not been shown to quantitatively predict clinical wear performance. ## Technological Characteristics Material: Cross-linked UHMWPE (irradiated to 7.5 Mrad in vacuum, remelted). Shell: Titanium alloy (Ti-6Al-4V). Form factor: Hemispherical liner, neutral/lateralized/lipped/face-changing orientations. Connectivity: None (mechanical implant). Sterilization: Not specified. ## Regulatory 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. ## Predicate Devices - DePuy Pinnacle® AltrX™ Acetabular Liners ([K062148](/device/K062148.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

K062148, October 24, 2006 | ### DEVICE DESCRIPTION: The DePuy Pinnacle AltrX Acetabular Liner is part of a modular system designed to replace the natural articular surface of the hip joint in total hip replacement. The liner is manufactured from ultra high molecular weight polyethylene (UHMWPE), which locks into a porous coated, hemispherical outer shell component manufactured from titanium alloy (Ti-6A1-4V). The liner component articulates with a metal or ceramic femoral head of an appropriate diameter. The subject Pinnacle AltrX liners are cross-linked UHMWPE acetabular cup liners that are available in a neutral, lateralized neutral, lipped or lateralized face-changing orientation. The {1}------------------------------------------------ K072913 * 2/3 subject liners are intended for use with modular, self-centering (bipolar), M-Spec or ceramic femoral heads within the 28mm-48mm size range. The following marketing claim will be made for the Pinnacle Altrx liner: Pinnacle AltrX UHMWPE liners (articulated against ceramic heads) reduce wear by 33% compared to articulation against cobalt-chromium heads. An in-vitro hip simulator wear study was conducted to support these wear claims. The study was conducted using test devices identified as AltrX Polyethylene Liners and control devices identified as AltrX or Enduron™ Polyethylene Acetabular Cup Liners (inner diameter of 28 mm or 36 mm) used with DePuy cobalt chromium or Delta Ceramic Femoral Heads. The control devices are manufactured by DePuy Orthopaedics, Inc. of ram-extruded bars and machined into Pinnacle liners. The test devices are manufactured by DePuy Orthopaedics, Inc. of ram-extruded bars, irradiated to 7.5 Mrad in vacuum, remelted and machined into Pinnacle liners. The subject liners were not terminally sterilized prior to testing. Test and control liners were tested for 5 million cycles using a 12-station orbital bearing hip simulator manufactured by Shore Western Manufacturing Inc. The thickness of the test liner was 5.53 mm. The heads were roughened after 5 million cycles by tumbling for 30 minutes with a bauxite/alumina abrasive media in a tabletop tumbler made by A.E. Aubin Co. and tested for an additional 2 million cycles against the liners. The articulating components for the test and control liners include 28 mm and 36 mm CoCrMo femoral heads, and 36 mm ceramic femoral heads. The lubricant used in the study was 90% bovine serum with 0.2% NaN3 and 20mM EDTA. The wear rates determined at the conclusion of the study were 34.3 ± .51 mg/million cycles (mg/MC) for the 28 mm CoCrMo femoral head/Enduron group (control), 31.54 ± 0.8 mg/MC for the 36 mm CoCrMo femoral head/Enduron group (control), 4.99 ± 0.66 mg/MC for the 36 mm CoCrMo femoral head/AltrX (control), and 3.32 ± 0.38 mg/MC for the 36 mm ceramic femoral head/AltrX test group. Note: Reduced Wear Claims are based on the results of in-vitro hip wear simulator tests which have not been shown to quantitatively predict clinical wear performance ## INDICATIONS AND INTENDED USE: ### Indications: The Pinnacle AltrX Acetabular Cup Liners are indicated for use in total hip replacement procedures. Total hip replacement is indicated in the following conditions: - 1. A severely painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia. - 2. Avascular necrosis of the femoral head. {2}------------------------------------------------ - 3. Acute traumatic fracture of the femoral head or neck. - Failed previous hip surgery, including joint reconstruction, internal fixation, 4. arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or total hip replacement. - 5. Certain cases of ankylosis. The Pinnacle AltrX Acetabular Cup Liners are indicated for use with Pinnacle Acetabular Cups in cementless applications. ## Intended Use: The subject liner is intended to be used with the DePuy Pinnacle metal acetabular shells, and DePuy metal or ceramic femoral heads to resurface the acetabular socket in cementless total hip arthroplasty. 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. ### BASIS OF SUBSTANTIAL EQUIVALENCE: The DePuy Pinnacle AltrX Acetabular Liner described in this submission is identical to the DePuy Pinnacle AltrX Acetabular Liner previously cleared in K062148 on October 24, 2006. The subject liners have not been modified from the previously cleared Pinnacle AltrX liners, and based upon the referenced testing, DePuy wishes to make a claim of reduced wear when the subject liners are used with ceramic femoral heads. {3}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/3/Picture/1 description: The image is a black and white logo for the U.S. Department of Health and Human Services.
