DEPARTMENT OF HEALTH AND HUMAN SERVICES Food and Drug Administration ### Indications for Use 510(k) Number (if known) K170473 Device Name C2 femoral stem Indications for Use (Describe) Monolithic cementless stems are indicated for use in partial or total hip arthroplasty and they are intended for press-fit (uncemented) use. When used in total hip arthroplasty, monolithic cementless stems are with modular heads and compatible acetabular cups. When used in partial hip arthroplasty, they are intended for use with bipolar heads. Hip arthroplasty is intended for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions: · non-inflammatory degenerative joint disease including osteoarthritis, avascular necrosis and dysplasia; • rheumatoid arthritis; · revisions in cases of good remaining femoral bone stock; · treatment of femoral head and neck fractures. Type of Use (Select one or both, as applicable) > Prescription Use (Part 21 CFR 801 Subpart D) Over-The-Counter Use (21 CFR 801 Subpart C) #### CONTINUE ON A SEPARATE PAGE IF NEEDED.

It is a monolithic collarless stem available in 14 sizes for both standard and lateralized versions and 8 sizes in revision version. When used in total hip arthroplasty C2 femoral stems are coupled to previously cleared Limacorporate components: - . Biolox Delta femoral heads or Limacorporate Femoral Heads articulating with Limacorporate Cemented Cups or - Biolox Delta heads or Limacorporate Femoral Heads articulating with Delta TT ● Acetabular System. When used in partial hip arthroplasty the C2 femoral stem is coupled to previously cleared Limacorporate Lock Bipolar Heads. The C2 femoral stem is made of Ti6Al4V conforming to the specifications ASTM F1472 - ISO 5832-3. The stem is characterized by a 12/14 conical taper to be coupled to Limacorporate Femoral Heads, Biolox Delta femoral heads or Lock Bipolar Heads. In Traditional 510(k) – C2 femoral stem November 08, 2017 {4}------------------------------------------------ addition necks are mirror-polished to reduce abrasion of the UHMWPE cups in case of abnormal contact. The stem has a rectangular section and is characterized by a "V" shaped A-P profile to improve adaptability to the most common bone morphologies and to facilitate insertion of the stem in the canal. The C2 femoral stem is suitable for both first implant and revision versions. The first implant versions are available in standard and lateralized versions with different CCD angles (131° and 134°), offsets and stem lengths. #### Intended Use: Monolithic cementless stems are indicated for use in partial or total hip arthroplasty and they are intended for press-fit (uncemented) use. When used in total hip arthroplasty, monolithic cementless stems are intended for use with modular heads and compatible acetabular cups. When used in partial hip arthroplasty, they are intended for use with bipolar heads. Hip arthroplasty is intended for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions: · non-inflammatory degenerative joint disease including osteoarthritis, avascular necrosis and dysplasia; - rheumatoid arthritis; - · revisions in cases of good remaining femoral bone stock. - · treatment of femoral head and neck fractures. #### Predicate Devices: - H-MAX S stem (Limacorporate, K112091 K150855 K160011). ● - Alloclassic Zweymüller Stems (Zimmer, K962101, K030373, K033664); ● - SL-PLUS stem (Smith&Nephew, K072852, K120211, K143096); #### Reference Devices: - Modulus stem (Limacorporate, K112158). ● - Tibial winged broach (Limacorporate, K141934). o - H-MAX broach (Limacorporate, K112091). - Stem Impactor (Limacorporate, K100858). ● - Manual Impactor (Limacorporate, K151739). #### Comparable Features to Predicate Device(s): The C2 stems are similar to the predicate devices in terms of intended use, indications, design and materials. The C2 stems can be used in total hip arthroplasty as all predicates and they can be used also in partial hip arthroplasty in the same way of the previously cleared H-MAX S stem. All stems are intended for cementless use. The C2 femoral stems have a design which is similar to predicates. Like predicates, the Traditional 510(k) – C2 femoral stem November 08, 2017 {5}------------------------------------------------ subject device is available for first implant (in standard and lateralized versions, with different CCD angles, offsets and sizes) and for revision implant (in different sizes). The C2 stems are manufactured from the same materials as the H-MAX S stem. #### Non-Clinical Testing: The C2 femoral stem was tested for fatigue resistance. The following tests were performed to demonstrate substantial equivalency of the C2 femoral stem to predicate devices: - . Fatigue Test according to ISO 7206-4; - Fatigue Test according to ISO 7206-6. . A simulation of Range of Motion has been performed to ensure the device design does not overly limit range of motion. All mechanical tests were performed on worst case components or constructs. The tests results demonstrated the device's ability to perform under expected clinical conditions. Endotoxin testing has been performed on Limacorporate products. #### Clinical Testing: Clinical testing was not necessary to demonstrate substantial equivalence of the C2 femoral stem to the predicate devices.
