AI/ML Overview

The provided text describes the regulatory review for a medical device called the "Origin™ TT Stem," which is a femoral hip prosthesis. However, the document does not contain any information regarding acceptance criteria, study methodologies for device performance, sample sizes, expert involvement, ground truth establishment, or multi-reader multi-case studies.

The document primarily focuses on:

Regulatory classification and product codes for the device.
Indications for Use of the hip replacement system, including various components beyond just the Origin™ TT Stem.
Comparison to predicate devices to establish substantial equivalence.
Non-clinical performance testing (Range of Motion, Stem and Neck Fatigue FEA, Stem and Neck Fatigue Testing) conducted according to established ISO and ASTM standards to demonstrate the strength and safety of the device.

Therefore, I cannot provide the requested table or answer the specific questions about the study that proves the device meets acceptance criteria, as this information is not present in the provided text.

The document states:

"Non-clinical testing and engineering evaluations were conducted to verify that the performance of the Signature Orthopaedics Origin™ TT Stem is adequate for anticipated in-vivo use."
"The results of non-clinical testing show that the strength of the Signature Orthopaedics Origin™ TT Stem is sufficient for their intended use and substantially equivalent to the legally marketed predicate device."

This indicates that internal testing was performed, but the details of the "acceptance criteria" and the specific data from these tests are not provided in the 510(k) summary. The document focuses on demonstrating that the device meets existing standards (ISO, ASTM) and is substantially equivalent to predicate devices, rather than presenting a clinical study with detailed performance metrics against specific acceptance thresholds.

Regulation Number and Section

§ 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)
Classification. Class II.
