The document is a 510(k) Premarket Notification Summary for a medical device (Osteonics® Universal Distal Hole Plug), which focuses on demonstrating substantial equivalence to previously cleared predicate devices.

Therefore, I cannot populate the table or answer the specific questions related to acceptance criteria and study details. The document primarily describes:

• Device Identification: Osteonics® Universal Distal Hole Plug (K992462)
• Sponsor Information: Howmedica Osteonics Corp.
• Classification: Surgical Mesh 21 CFR §878.3300
• Predicate Devices: Osteonics® Omnifit® Universal Distal Cement Spacer (K914406) and Osteonics® Universal Distal Spacer (K894708)
• Device Description: Single-use, made from PMMA or PMMA mixed with Barium Sulfate, cylindrical, rounded tip, friction-fit design to secure in the distal hole of a cemented hip stem.
• Intended Use: For cement spacers, mid-shaft restrictors, and cement plugs in cemented hip arthroplasty, when the device is considered advantageous.
• Technological Comparison: Substantially equivalent in material and basic mechanical function to predicate devices, but lacks fins and is available in one universal size.

The FDA's letter (pages 2-3 of the input) confirms the substantial equivalence determination but does not detail performance studies or acceptance criteria.

In summary, the provided text does not contain the information requested in your prompt regarding acceptance criteria and performance studies.
