Hi jwelch_81,
The rods, plates, screws, wires, pins and other internal fixation devices used in orthopedic reconstruction most often are made of a special stainless steel alloy, although occasionally they may be made from titanium or non-metallic biomaterials.
Those with metallic devices sometimes do complain of localized discomfort in cold environments, especially when the devices are set close to the surface of the body, as they often would be in the facial area.
If your friend plans on diving largely in warm tropical waters, this probably would not be a major problem.
Helpful?
Regards,
