The Prime Acetabular Cup System is intended for use in total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions:
-
- non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, ankyloses, protrusio acetabuli, and painful hip dysplasia:
-
- inflammatory degenerative joint disease such as rheumatoid arthritis;
-
- correction of functional deformity; and,
-
- revision procedures where other treatments or devices have failed.
Shells with BIOFOAM® metal foam coating are intended only for uncemented arthroplasty.
The Prime Acetabular Cup System includes acetabular shells, acetabular liners, and optional cancellous bone screws. The design features are summarized below:

- Manufactured from A-CLASS® (highly crosslinked ultra-high molecular o weight polyethylene)
- Lipped Available in in Standard, or Face-changing Lateralized O configurations with 12 anti-rotational tabs
- Inner Diameter sizes 22mm to 44mm O
- Bone Screws ●
- Manufactured from titanium alloy o
- 6.5mm diameter O
- 0 Available in lengths 15mm to 80mm in 5mm increments
The subject Acetabular Liner has undergone design changes in regard to the locking detail; all other design aspects, intended use, fundamental scientific technology, and material remain identical to the predicate K170444 Acetabular Liner.
This looks like a 510(k) summary for a medical device (Prime Acetabular Cup System), which focuses on demonstrating substantial equivalence to a predicate device rather than presenting detailed clinical study results with acceptance criteria.
As such, it does not contain the specific information requested in your prompt regarding acceptance criteria, a study proving device meets acceptance criteria, sample sizes for test/training sets, data provenance, expert adjudication, MRMC studies, standalone performance, or ground truth establishment.
The document primarily provides:
- Device Description and Intended Use: Details the components of the Prime Acetabular Cup System (Acetabular Shells, Liners, Bone Screws) and their intended applications in total hip arthroplasty.
- Substantial Equivalence Justification: States that the device is substantially equivalent to predicate devices (PROCOTYL® PRIME Acetabular Cup System, K170444) based on identical indications for use, similar materials (for the liner, drawing on K052026), and unchanged design features for shells and screws since K170444.
- Nonclinical Testing: Lists bench tests performed on the subject device (liner push-out, lever-out, torque-out per ASTM F1820, ASTM STP1301) and references tests performed on the predicate device and deemed applicable (deformation, frictional torque, wear, fatigue, range of motion, screw properties).
- Clinical Testing: Explicitly states that clinical data was not provided for the subject devices.
- Biocompatibility: Justifies not performing specific biocompatibility tests on the subject implants as their materials and patient contact are identical to predicate devices.
- Compatibility Tables: Details compatibility with other MicroPort Orthopedics products.
- Sterilization Residuals: Discusses previous evaluations and current applicability.
Therefore, I cannot populate the requested table and answer your questions directly from the provided text. The document does not describe a study with acceptance criteria in the context of clinical performance or diagnostic accuracy, which is implied by your prompt's questions. It focuses on engineering and material equivalence testing for an orthopedic implant.
§ 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)
