The 510(k) summary describes a modular hip system with minor modifications to existing components. There is no mention of AI, ML, image processing, or any software-driven analysis or decision-making capabilities. The performance studies focus on material properties and fatigue testing, not algorithmic performance.
Yes.
The device is a hip implant system intended to treat significantly impaired joints due to various arthritic conditions, fractures, and other anatomical abnormalities, which demonstrates its therapeutic purpose.
No
This device is a hip implant system, which is a therapeutic device used for joint replacement, not a diagnostic device used for identifying medical conditions.
No
The device description clearly states it is a "modular hip system" consisting of "three primary components: the neck, the body, and the stem," which are physical implants.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant for replacing or revising hip joints due to various conditions like arthritis, fractures, and developmental abnormalities. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details a modular hip system consisting of physical components (neck, body, stem) designed to be implanted in the body.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting markers, or providing information for diagnosis.
- Performance Studies: The performance studies focus on mechanical properties and fatigue performance of the implant, which are relevant to a surgical device, not an IVD.
IVD devices are used in vitro (outside the body) to examine specimens from the human body to provide information for diagnosis, monitoring, or screening. This device is an in vivo (within the body) implant used for treatment.

Device Description
The UniSyn Hip System was originally cleared as a modular hip system for Hayes Medical under the name "Triton", modifications to the system were cleared in a subsequent submission by Hayes under the UniSyn name. Hayes Medical changed its name to Consensus Orthopedics in 2008. This system consists of three primary components: the neck, the body, and the stem. This submission is to addition of a set of modified ("Plus") stems.
These minor modifications in body thickness are designed to allow for better contact between the implant and the inner surface of the medullary canal during revision surgery. The sizes of stems offered with the modified design are within the ranges previously cleared for the UniSyn system. The Plus stems are offered in neutral or +1 mm styles, short or long, in 10 to 20 mm diameters, and lengths from 110 to 210 mm. There is no change to the manufacturing, packaging, or sterilization processes. This change will not affect the indications for use nor any of the labeling.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The UNISYN Hip System (UHS) implant components use the identical materials, design construct features of the predicate components. The UHS implant components were evaluated using a Failure Modes and Effects Analysis (FMEA). Distal fatigue performance of the UniSyn Plus grit blasted stem was evaluated per ISO 7206-4 on a worst case example. No other nonclinical bench testing was deemed necessary over that used in support of the predicates based on identical design and materials.

§ 888.3360 Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis.
(a)
Identification. A hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth.(b)
Classification. Class II.

Substantial Equivalence:
Technological Characteristics/Substantial Equivalence:
The new "Plus" stems for the UniSyn hip systems employ the same materials, basic design features, manufacturing processes, packaging, and indications as the predicate stems for the UHS. Therefore, the new Plus stems for use with the UNISYN Hip System are substantially equivalent to legally marketed predicate devices (Table 2.1).

Dear Mr. Hull:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
