Intended Use

The TaperSet™ Hip System is designed for total hip arthroplasty and is intended to be used with compatible components of the Consensus Hip System including the CS2™ Acetabular Cup 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. The Consensus acetabular cup components are intended for cemented or cementless use. The CS2 Ti plasma coated acetabular shell is intended for cementless use. The Consensus all-poly acetabular cup is intended for cemented use. The intended use or indications for use of the TaperSet™ Hip System are similar to its original clearance K102399 except the removal of ‘partial hip arthroplasty’ as the DAA surgical technique is only applicable to the total hip system.

Device Story

TaperSet™ Hip System comprises femoral stems and CS2™ acetabular components for total hip arthroplasty. System utilizes Direct Anterior Approach (DAA) surgical technique. Femoral stems (5-24mm) and RDP stems (10.5-24mm) are titanium alloy (Ti-6Al-4V) with proximal plasma-sprayed titanium. Acetabular shells (42-68mm) are titanium alloy with porous coatings (sintered/diffusion-bonded beads or plasma spray) and optional screw fixation. Liners consist of highly cross-linked UHMWPE or Vitamin-E blended UHMWPE (VitalitE). Components feature circumferential scallops for rotational security. Device is implanted by orthopedic surgeons in clinical/OR settings. No changes to device design, materials, or manufacturing were made for this clearance; submission focuses on validation of DAA surgical technique. System provides structural replacement for diseased/damaged hip joints, aiming to restore function and mobility.

Indications for Use

Indicated for total hip arthroplasty in patients with significantly impaired joints due to rheumatoid, osteo, or post-traumatic arthritis; failed prior hip procedures; proximal femoral fractures; avascular necrosis; non-union of femoral neck fractures; or conditions like congenital dysplasia, metabolic/tumorous conditions, or structural abnormalities.

Regulatory Classification

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.
