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. ## Classification Rationale Class II. ## Recent Cleared Devices (13 of 13) | Record | Device Name | Applicant | Decision Date | Decision | | --- | --- | --- | --- | --- | | [K201157](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K201157.md) | Prime BIOFOAM® Multi-Hole Shells | Microport Orthopedics, Inc. | Aug 24, 2021 | SESE | | [K201701](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K201701.md) | R3 HA Coated Acetabular Shells | Smith & Nephew, Inc. | Oct 6, 2020 | SESE | | [K182535](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K182535.md) | R3 Anteverted Liners | Smith & Nephew, Inc. | Nov 19, 2018 | SESE | | [K161233](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K161233.md) | OXINIUM DH Fermoral Heads | Smith & Nephew, Inc. | Dec 14, 2016 | SESE | | [K122382](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K122382.md) | DYNASTY BIOFOAM SHELL | Wrightmedicaltechnologyinc | Oct 22, 2012 | SESE | | [K113848](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K113848.md) | R3 XLPE LINERS | Smith & Nephew, Inc. | Apr 27, 2012 | SESE | | [K102370](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K102370.md) | R3 XLPE ANTEVERTED LINERS | Smith & Nephew, Inc. | Jan 19, 2011 | SESE | | [K093363](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K093363.md) | COCR AND OXINIUM FEMORAL HEADS AND R3 XLPE LINERS | Smith & Nephew, Inc. | Jan 26, 2010 | SESE | | [K092386](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K092386.md) | R3 MULTI-HOLE SHELLS AND 36MM XLPE ACETABULAR LINERS | Smith & Nephew, Inc. | Nov 3, 2009 | SESE | | [K070756](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K070756.md) | SMITH AND NEPHEW REFLECTION 3 ACETABULAR SYSTEM | Smith & Nephew, Inc. | Jun 6, 2007 | SESE | | [K061253](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K061253.md) | REFLECTION 3 ACETABULAR SYSTEM | Smith & Nephew, Inc. | May 31, 2006 | SESE | | [K960094](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K960094.md) | REFLECTION DUAL DIMENSION SHELL | Smith & Nephew Richards, Inc. | Mar 27, 1996 | SESE | | [K931107](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL/K931107.md) | LOGYK ACETABULAR COMPONENT SYSTEM | Arthronics, Inc. | Mar 28, 1994 | SESE | ## Top Applicants - Smith & Nephew, Inc. — 9 clearances - Arthronics, Inc. — 1 clearance - Microport Orthopedics, Inc. — 1 clearance - Smith & Nephew Richards, Inc. — 1 clearance - Wrightmedicaltechnologyinc — 1 clearance --- **Source:** [https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/MBL) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
