Relapse hub

Something has changed

You are not sure it is anything. That is the normal place to be. Start from what you are actually seeing.

Written by Heath, who has lived it: casts from birth, a fusion at sixteen, the US Army, and distance running.

Most people start here The foot feels tighter → Telling an ordinary stiff spell from a change that is going somewhere. The brace The brace got harder → Usually fit, growth or routine. Rule those out before anything else. By age Walking looks different → What is expected at each age, and what is not. Background Does this even happen? → How common relapse is, and why it is a known feature rather than a failure. Ongoing Nothing is wrong yet → What actually protects the correction over the years it takes. Step back Where am I in all this? → The whole treatment sequence, from diagnosis onward.

The distinction that decides it

Almost every relapse question resolves into one comparison, and it is worth learning early because it saves a great deal of worry:

What changed	Usually means
The brace got harder to tolerate	Fit, growth, illness or routine. Fixable, and common.
The foot got harder to position	A change in the foot. Worth a call rather than a wait.

A child who is fighting the boots is usually a child who is fighting the boots. A foot that resists going into a boot that fitted fine last month is a different conversation.

Start with what you see

What changed?

Pick the closest match. Each one tells you what it usually means, where to read next, and when it is worth a call.

The brace got harder to tolerate

Usually fit, growth, illness or routine. Fixable, and common.

Check firstBoot size, strap order and whether the heel is seating. A disrupted week counts too.

Read nextBrace fit, step by step.

Call whenIt keeps resisting after the fit is sorted, or the foot itself is harder to move into position.

The foot is harder to position

That is a change in the foot rather than the brace, and it is worth a call rather than a wait.

Why soonerEarly relapse is often handled with a short return to casting. Late relapse more often means surgery.

You do not needTo be sure before you call.

Walking looks different

What counts as normal changes with age, so the useful question is whether it is new, one-sided and repeating.

Worth notingToe-walking or turning in only on the treated side, or a heel that will not come down.

Read nextSigns at each age.

Call whenThe same change repeats over two weeks, or several appear together.

Nothing has changed, but I worry about it

That is a reasonable place to be. Relapse is a known feature of the condition, and the things that protect against it are mostly habits.

Read nextWhat protects the correction.

Worth knowingGood bracing lowers the risk substantially. It does not remove it, and a relapse would not be a verdict on you.

KeepFollow-up appointments, even when nothing seems wrong.

You do not need to be sure before you call

Waiting for certainty is the most common mistake here, and it is an expensive one. Early relapse is often handled with a short return to casting; late relapse more often means surgery. Nobody minds a call about a pattern that turns out to be nothing.

Is this relapse?

How do I know if this is relapse?

Relapse is a pattern, not a moment. One stiff day is noise; the same change repeating across two weeks, or several changes appearing together, is the signal worth acting on.

Should I call about one bad week?

If the change is in the foot and not the routine, yes. A foot becoming harder to position is worth a call even after a week, because early relapse is far easier to treat than late relapse.

Can relapse be reversed?

Early relapse is often managed with a short return to casting and a reset of bracing. Later relapse, in a stiffer foot, more often needs surgical options, which is why timing matters more than certainty.

Is a hard brace night a sign of relapse?

Usually not on its own. Brace resistance is common and often traces to fit, growth, illness or routine. It becomes a relapse question when the foot itself resists going in.
