DePuy Modular M Heads are indicated for use in total hip replacement procedures. Total hip arthroplasty is intended to provide increased patient mobility and reduce pain by replacing the damaged hip joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components. Total hip replacement is indicated in the following conditions:

1. A severely painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia.
2. Avascular necrosis of the femoral head.
3. Acute traumatic fracture of the femoral head or neck.
4. Failed previous hip surgery including joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or total hip replacement.
5. Certain cases of ankylosis.

I am sorry, but the provided text is a 510(k) summary for a medical device (DePuy Modular M Heads), and it does not contain any information about acceptance criteria, device performance studies, or clinical trial data.

The document focuses on:

• Device Description and Intended Use: What the device is made of, its sizes, and what medical conditions it's used for.
• Classification and Product Codes: Regulatory categories.
• Substantial Equivalence: Comparing the new device to previously cleared devices.
• FDA Correspondence: The official letter from the FDA regarding the 510(k) clearance.

Therefore, I cannot extract the specific information you requested regarding acceptance criteria and study details (like sample size, ground truth, expert qualifications, adjudication methods, or MRMC studies) because that information is not present in the provided text. This type of detailed study data is typically found in the full 510(k) submission, not in the public summary.
