The Impact PEEK Union Nail System is indicated for maintenance of alignment and fixation of bone fractures, osteotomies, arthrodeses or bone grafts in the presence of appropriate additional immobilization (e.g. rigid fixation implants, cast, brace).

The Impact PEEK Union Nail System represents a cutting-edge fixation device crafted from advanced HA Enhanced PEEK. The system is versatile, offering a range of lengths and diameters to suit various clinical needs, and features a cannulated design for precise k-wire guidance. Additionally, it integrates tantalum pins to ensure optimal imaging visibility, enhancing surgical accuracy and outcomes.

The SnapHammer Hammertoe Correction System is indicated for the fixation of osteotomies and reconstruction of the lesser toes following correction procedures for hammertoe, claw toe, and mallet toe. Cannulated implants in the SnapHammer Hammertoe Correction System can be used with K-wires for the delivery of implants or the temporary stabilization of outlying joints (e.g. MTP Joint).

The SnapHammer Hammertoe Correction System is comprised of an additively manufactured titanium fixation device attached to a snap-off post. The snap-off post aids in a quick insertion and snaps off after implant has been threaded in. The implants are offered in Ø3.0mm and Ø3.50mm diameters and in lengths ranging from 12mm to 15mm. The system includes drills, implant inserters, and sizers manufactured from medical grade stainless steel.

The provided FDA 510(k) Clearance Letter for the "SnapHammer Hammertoe Correction System" describes a medical device, specifically a metallic bone fixation fastener. This document is a regulatory clearance for a physical medical device, not a software or AI-based medical device.

Therefore, the information requested in your prompt regarding acceptance criteria and studies for an AI/software medical device (e.g., sample size for test set, data provenance, number of experts, adjudication methods, MRMC study, standalone performance, ground truth, training set information) is not applicable to the provided document.

The document states:

• "No FDA performance standards have been established for the SnapHammer Hammertoe Correction System."
• The non-clinical testing performed focused on:
  • "Engineering analysis comparing device characteristics including materials, intended use and processes (cleaning and sterilization methods)"
  • "The steam sterilization process has been validated per ISO 17665-1 & 17665-2 to a sterility assurance level of 10⁻⁶"
• The basis for equivalence is that the device "maintain[s] the same features as the previously cleared devices, but steam sterilization is being added as an alternative sterilization method."
• "This modification does not change the intended use or performance of the device and does not raise additional questions of substantial equivalence."

In summary, this clearance is for a physical orthopedic implant and is based on demonstrating substantial equivalence to a predicate device, primarily by showing that a new sterilization method does not alter its safety or efficacy, rather than AI/software performance metrics.
