Substantial equivalence is supported by non-clinical bench testing performed on the predicate TaperSet Hip System, including stem fatigue testing, range of motion analysis, porous coating characterization, polyethylene insert retention testing, and modular connection (fretting/corrosion) analysis. ## Technological Characteristics Materials: Titanium alloy (stem/shell), CoCr (femoral head), UHMWPE (insert). Coatings: CPTi plasma spray and CPTi beaded porous coatings. Design: Monolithic tapered stem, 12/14 Morse taper, hemispherical acetabular shell. Connectivity: None. Sterilization: Not specified. Software: None. ## 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 - Consensus Total Hip System ([K922561](/device/K922561.md)) - Consensus 22mm CoCrMo Femoral Head ([K960339](/device/K960339.md)) - Consensus 32mm CoCrMo Femoral Head ([K960156](/device/K960156.md)) - Consensus Apex Dome Hole Plug ([K960340](/device/K960340.md)) - Consensus TaperSet Hip System ([K102399](/device/K102399.md)) - CS2 Plus Acetabular Insert ([K100933](/device/K100933.md)) - Consensus Acetabular Shell, Ti Coated ([K020153](/device/K020153.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

uncemented prosthesis (21 CFR 888.3358, Class II device,
Product Code LPH). | | #### Device Description: The HELICON Hip System (HHS) is a porous-coated, semi-constrained, hip prosthesis designed for either primary or revision hip arthroplasty. The HHS includes a femoral stem, a CoCr femoral head, non-crosslinked UHMWPE insert, acetabular shell and bone screws. The HHS stem is a monolithic, titanium alloy, tapered hip stem available with a proximal CPTi plasma porous coating. The stem has a dual wedge geometry and is available in both standard and 7mm lateral offsets in sizes ranging from 7.5mm to 24mm. The stems feature a neck shaft angle of 135° and a 12/14 Morse taper trunnion. HHS stems are compatible with the HHS CoCr femoral head and HHS acetabular insert. The HHS CoCr head is highly polished and available in multiple offsets and diameters (22, 28, and 32mm). The HHS acetabular components include a titanium alloy shell and a mating UHMWPE insert. The shell is a hemispherical design, is available with or without screw holes, and employs a CPTi beaded, porous coating. The UHMWPE insert is available in 20° hooded or nonhooded (neutral) configurations in inner diameters of 22, 28, and 32mm. Titanium alloy bone screws are available for additional fixation. #### Indications for Use: The HELICON™ Hip System is designed for total hip arthroplasty. The indications for use are: - A. Significantly impaired joints resulting from rheumatoid, osteo, and post-traumatic arthritis. {1}------------------------------------------------ #### TGM Medical, Inc Premarket Traditional 510(k) Notification: HELICON Hip System Page 2 of 3 - B. Revision of failed femoral head replacement, cup arthroplasty or other hip procedures. - C. Proximal femoral fractures. - D. Avascular necrosis of the femoral head. - E. Non-union of proximal femoral neck fractures. - F. Other indications such as congenital dysplasia, arthrodesis conversion, coxa magna, coxa plana, coxa vara, coxa valga, developmental conditions, metabolic and tumorous conditions, osteomalacia, osteoporosis, pseudarthrosis conversion, and structural abnormalities The HELICON™ hip stem is indicated for cementless use. The HELICON™ acetabular shell component is indicated for cemented or cementless use. ### Substantial Equivalence: ## Technological Characteristics/Substantial Equivalence: The HHS is equivalent to predicate systems in design geometry, materials, performance testing and indications for use. Consensus Orthopedics, Inc. (COI) licensed their previously cleared hip components to TGM Medical, Inc. The hip components consist of the previously cleared TaperSet Hip System femoral stem (K102399), CoCr femoral heads (K922561, K960339, and K960156), UHMWPE inserts (K922561 and K020153), acetabular shell (K922561) and titanium bone screws (K922561). The HHS hip components therefore have the same technological characteristics to those used in the Consensus Taper Set Hip System. Based on the identical material, characterization data, geometry and mechanical testing, the HHS system is substantially equivalent to legally marketed predicates (Table 2.1). | 510(k)

The HELICON Hip System (HHS) implant components use the identical materials, design construct features (e.g., including locking mechanisms of the polyethylene insert to the metal shell and the exterior coatings) of the predicate components. No changes were made to the predicate components that required additional testing. The HHS implant components + {2}------------------------------------------------ ### TGM Medical. Inc Premarket Traditional 510(k) Notification: HELICON Hip System Page 3 of 3 -111472 were evaluated using a Failure Modes and Effects Analysis (FMEA). No additional nonclinical bench testing was deemed necessary over that used in support of the predicates based on identical design and materials. Predicate bench testing included distal and proximal stem fatigue testing of the worst-case stem consistent with the "Guidance for Industry and FDA Staff Non-clinical Information for Femoral Stem Prostheses;" Range of Motion analysis; CPTi plasma sprayed and CPTi beaded metallic coating characterization per the "Guidance Document for Testing Orthopedic Implants with Modified Metallic Surfaces Apposing Bone or Bone Cement;" CPTi plasma spray characterization per the "Guidance for Industry on the Testing of Metallic Plasma Sprayed Coatings on Orthopedic Implants to Support Reconsideration of Postmarket Surveillance Requirements;" polyethylene insert retention mechanism testing; and bone screw mechanical strength testing. Additionally, modular connection analyses including fretting and corrosion of the metallic femoral heads for compatibility and pin-on-flat testing of the non-crosslinked UHMWPE/CoCr material combination were also performed. Both the CPTi plasma sprayed coating and the CPTi beaded coating characterizations meet the regulatory definition of porous coating for the hip construct per 21 CFR 888.3358. All of the observed results for the predicate TaperSet Hip System had been found substantially equivalent prior to devices currently marketed. The subject Helicon Hip System is identical in material and design to that of the TaperSet Hip System. Therefore, the subject device is as safe, as effective, and performs at least as safely and effectively as legally marketed predicates. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for the Department of Health & Human Services USA.
