The hip prostheses QUADRA-P and QUADRA-P collared are designed for cementless use in total or partial hip arthroplasty, for primary or revision surgery. The hip prosthesis QUADRA-P cemented is designed for cemented use in total or partial hip arthroplasty in primary or revision surgery. Hip replacement is indicated in the following cases: · Severely painful and/or disabled joint as a result of arthritis, rheumatoid polyarthritis or congenital hip dysplasia · Avascular necrosis of the femoral head · Acute traumatic fracture of the femoral head or neck · Failure of previous hip surgery: joint reconstruction, arthrodesis, partial hip arthroplasty, hip resurfacing replacement or total hip arthroplasty
The Quadra-P implant subject of this submission is a line extension to the currently cleared Ouadra-P implants (K181254 and K192827). The stem subject of this submission is a range extension of the Quadra-P Short Neck Standard stem cleared under K192827. The Quadra-P implant subject of this submission is the Quadra-P Short Neck STD stem size 00, a coated cementless stem, commercial reference 01.12.249. The Quadra-P implants are part of the Medacta Total Hip Prosthesis system. The Medacta Total Hip Prosthesis system consists of femoral stems, modular femoral heads, and acetabular components. Ouadra-P family includes cementless and cemented stems. Quadra-P, Quadra-P Short Neck, and Quadra-P Collared implants are cementless stems made with a titanium alloy substrate (Ti6Al7Nb) according to ISO 5832-11 Second Edition 2014-09-15: Implants for Surgery - Metallic Materials - Part 11: Wrought Titanium 6-Aluminium 7-Niobium Alloy. The femoral stems have a Eurocone (12/14 taper) and polished necks. Quadra-P, Quadra-P Short Neck, and Quadra-P Collared implants have an air plasma sprayed Titanium Y367 and Hydroxyapatite Osprovit (HA) dual layer coating on the proximal end of the shaft. The dual coating covers approximately 50% of the stem length. The distal part of the stem is coated with hydroxyapatite after sandblasting. Also included in Quadra-P family, are the Quadra-P Cemented stems manufactured from High Nitrogen Stainless Steel. The acetabular components consist of metal cups and liners made of ultra-high molecular weight polyethylene (UHMWPE) or Highcross highly crosslinked ultra-high molecular weight polyethylene (HXUHMWPE). Acetabular components include the Mpact DM (K143453). VersafitCup (K083116 and K092265), VersafitCup CC Trio (K103352), Mpact (K103721 and K132879), Mpact 3D Metal (K171966), and Medacta Bipolar Head (K091967). The Quadra-P implants can be combined with the CoCr Ball Heads (K072857 and K080885). Endo Head (K111145), MectaCer Biolox Option Heads (K131518), or MectaCer BIOLOX® Forte (K073337) or MectaCer BIOLOX® Delta Femoral Heads (K112115).
This document is a 510(k) Premarket Notification for a medical device (hip prosthesis). It does not contain information about an AI/ML-driven medical device or a study involving AI/ML performance. Therefore, it is impossible to extract the requested information regarding acceptance criteria and study details for an AI-driven device.
The document primarily focuses on demonstrating substantial equivalence of a new size of a Quadra-P hip prosthesis to previously cleared versions and other predicate devices. The "Performance Data" section details non-clinical mechanical studies (fatigue tests, range of motion, pull-off force, coating tests, pyrogenicity) conducted on the physical device, not on an algorithm's performance. It explicitly states: "No clinical studies were conducted."
To answer the user's request, I would need a document describing the validation of an AI/ML-driven medical device.
§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.
(a)
Identification. A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.(b)
