Device Description

The Converge Acetabular System consists of the following shell components:

I. Hemispherical: The Converge Hemispherical Shell is a porous coated, Ti-6A1-4V (ASTM F136) shell. The outer surface of the shell has CSTi porous coating (commercially pure titanium) to provide for biological fixation. The shell is available in various sizes ranging from 39mm to 65mm (in 2mm increments). The shell features 2 screwhole plugs that are sintered in place. The screwhole plugs can be removed intraoperatively before or after implantation if the surgeon opts to enhance fixation of the shell with bone screws. When left in place (no supplemental screws used), the screwhole plugs limit material ingress and egress (e.g., tissue, debris particles, cement, etc.).
II. Rim-Flare: The Converge Rim Flare Shell is a Ti-6AI-4V metallic acetabular shell coated with CSTi porous coating. It is designed with an offset outer radius in the rim region which permits the loads to be transmitted to the periphery of the outer surface. An initial press-fit of the component is achieved by the offset radius in this region. Additionally, the outer design of the shell incorporates three pegs which are press-fit into the cancellous bone of the reamed acetabulum to minimize the potential for tilting or rotation of the device. The shell is available in various sizes ranging from 39mm to 71mm (in 2mm increments).
III. Revision: The Converge Revision Shell is a Ti-6Al-4V metallic acetabular shell coated with CSTi porous coating. The Revision shell has up to nine screwholes which allow for screw placement into the illum, ischium and pubis. Those screwholes that are not utilized may be plugged after implantation to limit passage of tissue, debris particles, cement, etc. The shell is available in various sizes ranging from 43mm (in 2mm increments).
All three Converge shells feature a central dome hole which allows for interface with the impactor/alignment instrument as well as for visualization of the acetabulum to ensure complete seating of the device. The dome hole may be plugged using a threaded cover to restrict unwanted material migration through the hole.
All three of the Converge shell components will use existing Inter-Op instrumentation and will mate with currently marketed Inter-Op Acetabular Inserts (oxygenless packaged polyethylene, Durasul, or Metasul).

AI/ML Overview

The provided text is a 510(k) summary for the Sulzer Orthopedics Converge Acetabular System. It details the product, its intended use, and claims substantial equivalence to a previously cleared device. However, it does not contain any information regarding acceptance criteria, device performance studies, sample sizes, expert qualifications, or ground truth establishment.

Therefore, I cannot provide the requested table or answer the specific questions about the study that proves the device meets the acceptance criteria. The document focuses on regulatory compliance through substantial equivalence, not on a performance study with defined acceptance criteria.

III. Revision

The Converge Revision Shell is a Ti-6Al-4V metallic acetabular shell coated with CSTi porous coating. The Revision shell has up to nine screwholes which allow for screw placement into the illum, ischium and pubis. Those screwholes that are not utilized may be plugged after implantation to limit passage of tissue, debris particles, cement, etc. The shell is available in various sizes ranging from 43mm (in 2mm increments).

All three of the Converge shell components will use existing Inter-Op instrumentation and will mate with currently marketed Inter-Op Acetabular Inserts (oxygenless packaged polyethylene, Durasul, or Metasul).

SPECIFIC DIAGNOSTIC INDICATIONS

Components of the Converge Acetabular System are intended for use in total hip arthroplasty for treatment of the following:

patient conditions of noninflammatory degenerative joint disease (NIDJD); e.g., avascular ● necrosis, osteoarthritis, and inflammatory joint disease (IJD), e.g., rheumatoid arthritis.
those patients with failed previous surgery where pain, deformity, or dysfunction persists. ●
revision of a previously failed arthroplasty where there is sufficient bone stock to support the . implant.

SUBSTANTIAL EQUIVALENCE

Substantial equivalence is based on comparison to the Inter-Op Acetabular System. The fundamental scientific technologies previously incorporated into the Inter-Op Acetabular System have not changed in the Converge Acetabular System. The main difference is relative to changes being made to the manufacturing process which should provide additional assurance of cleanliness. These manufacturing process changes have also necessitated some minor changes in design for the Converge, all of which were assessed relative to the Inter-Op and found to be acceptable.

Based on conformance with the design control requirements as specified in 21 CFR 820.30 and similarities in design, materials, sterilization, intended use and indications for use, we believe that the Converge Acetabular System is substantially equivalent to the previously cleared Inter-Op Acetabular System.

Regulation Number and Section

§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.

(a)
Identification. A hip joint metal/polymer semi-constrained cemented 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 includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.
