The ESKA Modular Hip System is indicated for use in the treatment of severely disabled hip joints resulting from painful osteo-, rheumatoid, and post-traumatic arthritis, and the late stages of avascular necrosis, and for the revision of previous hip surgeries.
The ESKA Modular Hip System is a total hip system used for the replacement of severely disabled hip joints. It consists of femoral stems and heads, acetabular shells and modular liners, bipolar femoral heads, and bone screws. The femoral stems are anatomically designed in left and right configurations, with anteverted femoral necks. There are fully porous, proximally porous. collared and collarless options. The acetabular components are porous, with various liner options and screws for supplementary fixation. Pre-assembled bipolar and unipolar components are also available.
The provided text describes the ESKA Modular Hip System, a total hip replacement system, and its 510(k) premarket notification. However, it does not contain any information about acceptance criteria, device performance studies, sample sizes, expert involvement, or any other data related to clinical or performance testing.
The document is a submission summary to the FDA and the FDA's response letter, which asserts substantial equivalence to predicate devices based on design, function, material, and intended use, rather than detailed performance data from a specific study of the ESKA Modular Hip System itself.
Therefore, I cannot populate the table or answer the specific questions about acceptance criteria and study details based on the provided text.
No information regarding acceptance criteria or a study proving the device meets said criteria is 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)
