Page Type
Product Code
Definition
An ankle joint metal/polymer non-constrained uncemented prosthesis is a device intended to be implanted to replace an ankle joint. The device limits minimally (less than normal anatomic constraints) translation in one or more planes. It has no linkage across-the-joint. This generic type of device includes prostheses that have a tibial component made of alloys, such as cobalt-chromium-molybdenum, and a talar component made of ultra-high molecular weight polyethylene.

No Linked CFR Text

The FDA has not linked product code NTG to any particular section of the CFR (Code of Federal Regulations). There are multiple reasons why this might be the case:

  • The product code was created for a class III submission that does not follow the normal PMN or PMA path - e.g., for a device that falls under HDE (Humanitarian Device Exemption) or EUA (Emergency Use Authorization).
  • The FDA has generated the product code for an existing Class III device, as a result of a PMA supplement that modifies the device in a way that it can't fit under the existing product code originally assigned
  • The product code was created for internal use at the FDA, and not for classification or regulatory-related purposes.
