The metal is rarely the problem
Screws and plates generate more anxiety in applicants than they generate concern in reviewers. What a reviewer wants to know is why the hardware was needed and what the joint does now. The metal itself is mostly inert, mostly permanent and mostly beside the point. Seven things people believe about it, checked one at a time.
Checked
What people believe about hardware
“Metal in your foot is an automatic disqualification.” What actually applies
Retained hardware is assessed, not prohibited. The questions are whether it is stable, whether it causes symptoms, and what the underlying repair means for function. Three separate things, none of which is answered by the presence of metal.
Plenty of people serve with screws and plates in place, including in the foot and ankle. The reason to be careful is the injury the hardware was fixing, not the fixing.
“I should have it removed before applying.” Why that usually backfires
Removal is surgery, and surgery resets the clock. You trade a settled situation that has been quiet for years for a fresh operation, a recovery period, and a new question about whether the repair holds without support.
Where removal is genuinely indicated (prominent hardware causing pressure in a boot, loosening, or a screw sitting where it will be repeatedly struck) it is a good idea for medical reasons that happen also to help the application. Doing it purely to present a cleaner set of X-rays rarely pays.
“It will set off airport scanners and metal detectors.” What actually happens
Most orthopedic implants are titanium or stainless alloys in small volumes, and modern walk-through detectors are generally not tripped by a couple of screws in a foot. Some people do get flagged, more often with larger implants.
Nothing in accession or retention turns on this. It is a genuinely common worry and a genuinely irrelevant one.
“Cold weather makes hardware ache, so I would struggle in the field.” What is really going on
The reported ache is common and the usual explanation, metal conducting cold, does not survive scrutiny, since a screw inside a foot sits at body temperature. The likelier drivers are the surrounding scarred tissue, altered blood flow and stiffened joints responding to cold, which they would do with or without the implant.
The practical point stands regardless: if cold reliably makes your foot worse, field conditions will find that out, and it is worth knowing before you sign rather than after.
“Hardware makes the bone weaker.” What the mechanics are
Fixation exists to hold bone in position while it heals, and a healed bone with hardware in it is generally as strong as it was going to be. The implant is not carrying the load once union is complete.
The caveat: screw holes and plate edges create stress concentrations, and a bone can occasionally fracture at those points under a large enough force. That is a low-probability event and not a general weakness, and it is one reason a reviewer will want to see that union was achieved properly.
“If I do not mention it, nobody will find out.” How this ends
Hardware is visible on any imaging of the area, and imaging happens: after an ankle injury on exercise, before an unrelated procedure, during a medical board. It also comes with a scar that an examiner will ask about.
Undisclosed history is fraudulent enlistment. Discovering it years in, attached to an injury, converts an ordinary disclosure into a serious problem with career consequences. There is no version of this where concealment is the better bet.
“Old childhood hardware is the same as recent hardware.” Why the difference is large
A pin placed at eight years old and quiet ever since has thirty years of demonstrated tolerance behind it. A plate fitted eighteen months ago has eighteen months. Reviewers weigh time heavily because time is the only real evidence of durability anyone has.
This works in the favor of most people reading this site, whose hardware went in during childhood clubfoot (club foot) treatment and has been unremarkable since. Say how long it has been there, plainly, because it is the strongest fact you have.
What a reviewer is actually asking
Strip away the anxiety about metal and the review reduces to three questions, in order of weight.
Notice that only the middle one is about the implant at all, and it is the easiest of the three to document. If you have a recent film showing solid union and hardware in good position, that question is closed before it is asked.
Nobody is worried about the screw. They are worried about why the screw was necessary.
The one hardware issue that genuinely affects service
Prominence. A screw head or plate edge sitting just under the skin, in a place where a boot collar or a strap presses on it, produces a small, stupid, persistent problem that no amount of motivation solves. It rubs, it inflames, and it does so every day because you cannot take the boot off.
This is worth checking before you apply instead of discovering in week three. Press along the scar and over any hardware you can feel, then put on the stiffest boot you own and walk in it for a few hours. If something localized starts complaining, that is the conversation to have with a surgeon. And it is one of the few situations where removal is straightforwardly the right answer.

One sentence in the instruction settles most hardware questions
The paragraph on retained fixation ends by saying hardware is not disqualifying where fractures are healed, ligaments are stable and there is no pain. Three conditions, all documentable. That paragraph is quoted whole, with its number, in a 14-page guide covering ten others besides.
