WHERE THE USE OF A MORE CONSERVATIVE PROCEDURE HAS FAILED OR IS UNACCEPTABLE
INTENDED FOR NON-CEMENTED USE SINGLE USE ONLY
The Signal Medical Corporation HHS Acetabular Component is manufactured of ASTM I-136 or F-75. The design is made available in twelve (12) sizes ranging from 48mm to 70mm, in two mm increments. The cup is coated with an F-67 sintered beaded surface for F-136 or F-75 beads for an F-75 cup to enhance bone ingrowth. The device is designed in three models, one with three circumferentially spaced pins or spikes at 120 degree intervals to provide for a primary skeletal fixation and reduce the chance of rotation, one with screw holes and one with both screw holes and spikes. The ultra high molecular weight polyethylene inserts, ASTM F648, are secured to the acetabular shell using a crown-taper fit. They are designed to accept 28mm femoral heads on their inside diameter from 48mm to 70mm and 32mm femoral heads from 54mm to 70mm. This device is intended for single use only.
This document is a 510(k) summary for a medical device (HHS Acetabular Component), not a study report for an AI/ML powered device. As such, it does not contain information about acceptance criteria, device performance, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, or training set details that are typically found in such studies.
Therefore, I cannot provide a table of acceptance criteria and reported device performance or other requested information as it is not present in the provided text.
§ 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)
