Intended Use
The TaperSet™ Hip System is designed for total or partial hip arthroplasty and is intended to be used with compatible components of the Consensus Hip System. The indications for use are: - A. Significantly impaired joints resulting from rheumatoid, osteo, and post-traumatic arthritis. - 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 TaperSet™ hip stem is indicated for cementless use.
Device Description
The TaperSet Hip System (THS) is a monolithic, titanium alloy tapered hip stem design with a proximal, plasma sprayed, porous CPTi coating. The stem has a dual wedge geometry and is available in both standard and 7mm lateral offsets in sizes designated as 7.5mm to 24mm. The stems feature a neck shaft angle of 135° and a 12/14 Morse taper trunnion. The TaperSet Hip System is designed for total or partial hip arthroplasty and is intended to be used with compatible components of the Consensus Hip System. The stem is compatible with previously cleared CoCr heads, zirconia or Biolox delta ceramic heads, unipolar heads, bipolar heads, UHMWPE inserts and acetabular cups. The modification addressed here is the addition of a line of stems with a reduced distal profile (RDP) in sizes 10.5mm to 24mm.
More Information

No
The summary describes a mechanical hip implant and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

Yes.
The device is a hip implant designed to treat various joint conditions and injuries, which falls under the definition of a therapeutic device as it treats or alleviates a disease or injury.

No

This device is a hip implant system designed for hip arthroplasty, which is a surgical procedure to replace parts of the hip joint. It is not used to diagnose a medical condition.

No

The device description clearly states it is a monolithic, titanium alloy tapered hip stem, which is a physical implant, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Description: The TaperSet™ Hip System is a physical implant (a hip stem) designed to be surgically placed within the human body to replace or augment a damaged hip joint.
  • Intended Use: The intended use clearly describes a surgical procedure (total or partial hip arthroplasty) to address structural and functional issues of the hip joint. It does not involve testing samples outside the body.

Therefore, the TaperSet™ Hip System falls under the category of a surgical implant or prosthetic device, not an in vitro diagnostic.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

No additional non-clinical testing was performed because there was no proximal design change from the predicate TaperSet and distally the new smallest size is still larger than the smallest predicate TaperSet stem which was previously tested.

Based upon engineering analysis of the design modification the new reduced distal profile stems for the TaperSet Hip System by Consensus are substantially equivalent to devices currently marketed. Therefore, the device is as safe, as effective, and performs at least as safely and effectively as legally marketed predicates.

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.

(a)
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.(b)
Classification. Class II.

The TaperSet™ hip stem is indicated for cementless use.

Substantial Equivalence:

Technological Characteristics/Substantial Equivalence:

The new Reduced Distal Profile (RDP) stems for the TaperSet Hip System have the identical neck and taper design, porous coating, and sizing as the predicate TaperSet stems cleared under K 102399 in design and indications. A reduced distal profile femoral hip stem design was previously cleared by FDA under K101086 for the Biomet Taperloc Complete Hip System. The subject Consensus RDP stems are still compatible with previously cleared CoCr heads, zirconia and Biolox delta ceramic heads, unipolar heads, bipolar heads, UHMWPE inserts and acetabular cups. Based on the material, characterization data, and geometry, the TaperSet Hip RDP stem is substantially equivalent to the legally marketed predicates.

Non-Clinical Performance Data:

No additional non-clinical testing was performed because there was no proximal design change from the predicate TaperSet and distally the new smallest size is still larger than the smallest predicate TaperSet stem which was previously tested.

Based upon engineering analysis of the design modification the new reduced distal profile stems for the TaperSet Hip System by Consensus are substantially equivalent to devices currently marketed. Therefore, the device is as safe, as effective, and performs at least as safely and effectively as legally marketed predicates.
