This specification covers total wrist implants that provide articulation function through radial carpal components. However, this specification does not include implants with ceramic coated or porous coated surfaces, one-piece elastomeric implants, and those used for custom applications. Implants covered by this specification are of the constrained, partially constrained, or unconstrained joint prosthesis type. The implants shall be manufactured from biocompatible materials made of unalloyed titanium, cobalt-28chromium-6molybdenum alloy, wrought cobalt-20chromium-15tungsten-10nickel alloy, wrought titanium-6aluminum-4vanadium extra low interstitial alloy, wrought 35cobalt-35nickel-20chromium-10molybdenum alloy, wrought cobalt-20nickel-20chromium-3.5molybdenum-3.5tungsten-5iron alloy, cobalt-28chromium-6molybdenum alloy, titanium-6aluminum-4vanadium alloy, or wrought cobalt-28chromium-6molybdenum alloy with dimensions in conformity to the requirements specified. Tests for polymeric creep (cold flow), wear, and range of motion of the device as well as in vitro laboratory testing shall be performed and shall conform to the requirements specified. Per service requirement, metallic implants shall undergo fluorescent penetrant inspection, while cast metallic implants shall undergo radiography.
