Qué bien que en urgencias no le hayan puesto yeso y que ya pueda andar sin muletas.

It is an exclamatory reaction meaning something like How good that..., That’s great that..., or So good that....

It is not just describing a fact; it shows the speaker’s positive feeling about the situation. That emotional reaction is important, because it helps explain why the subjunctive is used later.

Because Qué bien que expresses emotion or evaluation. In Spanish, when you react to a situation with feelings such as खुशी, surprise, relief, sadness, etc., the following clause usually goes in the subjunctive.

So in this sentence, the speaker is pleased about two things:

• que ... no le hayan puesto yeso
• que ya pueda andar sin muletas

Both are presented as things the speaker is happy about, not as neutral facts.

Hayan puesto is the present perfect subjunctive of poner.

It is made from:

• hayan = subjunctive of haber
• puesto = past participle of poner

So:

• poner → puesto
• not ponido — puesto is irregular

This form is used here because the action of putting on a cast is seen as already completed.

Because the sentence is still under the emotional trigger Qué bien que. After that kind of expression, standard Spanish uses the subjunctive, not the indicative.

So:

• Qué bien que no le hayan puesto yeso = correct
• Qué bien que no le han puesto yeso = not the normal choice here

The indicative han puesto would sound like a straightforward statement of fact, but the speaker is reacting emotionally to it.

For the same reason: it depends on Qué bien que, which triggers the subjunctive.

• pueda = present subjunctive of poder
• puede = present indicative

The speaker is saying they are happy that the person is now able to walk without crutches, so Spanish uses the subjunctive in that subordinate clause.

Because the two clauses refer to different time relationships.

• no le hayan puesto yeso: this is a completed action in the past, connected to the present result. That is why Spanish uses the present perfect subjunctive.
• ya pueda andar sin muletas: this is a present or current ability. That is why Spanish uses the present subjunctive.

So the tense choice matches the meaning:

• first: something that has already happened
• second: something that is true now

Le is an indirect object pronoun here, meaning to him, to her, or to you (formal singular), depending on context.

In this sentence, it refers to the person who might have received the cast:

• ponerle yeso a alguien = to put a cast on someone

Spanish often uses an indirect object pronoun with verbs like poner when something is being put on a person.

So no le hayan puesto yeso literally works like they haven’t put plaster/cast on him/her.

Yes. Le does not tell you the gender.

It can mean:

• to him
• to her
• to you (formal singular)

You need context to know who the person is.

In Spain, urgencias commonly means the emergency department, ER, or A&E.

It is normally used in the plural as a fixed expression:

• ir a urgencias = to go to the ER
• estar en urgencias = to be in the ER

So en urgencias means in/at the ER.

This is very common in Spain. In English it may feel strange because urgencies does not work the same way, but in Spanish this is normal.

Because in Spanish, certain places and services often appear without an article in common expressions, especially when the meaning is institutional or functional rather than physical.

So en urgencias sounds natural as at the ER.

You may also hear fuller versions such as en el servicio de urgencias, but en urgencias is the everyday way to say it.

Literally, yeso means plaster. In this medical context, it refers to a cast.

So poner yeso means to put a cast on someone.

In Spain, you may also hear escayola for a plaster cast, depending on the speaker and region.

Both can exist, but they feel slightly different.

• poner yeso focuses on the treatment/material in a general way
• poner un yeso points more to a specific cast

In medical Spanish, leaving out the article is very natural when talking about treatment or procedure in a general sense.

So no le hayan puesto yeso sounds like that they didn’t put him/her in a cast.

Because there are two coordinated subordinate clauses, and both depend on Qué bien:

• que en urgencias no le hayan puesto yeso
• y que ya pueda andar sin muletas

Repeating que is the normal and clearest way to link two full clauses like this.

In English we might sometimes avoid repeating that, but in Spanish repeating que is very common and often preferred.

Here andar means to walk or to get around on foot.

In many contexts, andar and caminar can both be translated as to walk, but they are not always identical in feel.

In this sentence, andar sounds very natural because the focus is on mobility after an injury:

• ya pueda andar sin muletas = that he/she can now walk/get around without crutches

Caminar would also be possible, but andar is especially common in everyday Spanish.

Ya means already or now.

It shows progress or a change in situation. The idea is that before, the person could not walk without crutches, but now they can.

So ya pueda andar sin muletas suggests:

• can already walk without crutches
• is now able to walk without crutches

Without ya, the sentence would lose that sense of improvement.

Yes, in practice it works a lot like English they, but Spanish often leaves the subject unstated when it is obvious or unimportant.

Here the implied subject is something like:

• the doctors
• the hospital staff
• the people in the ER

Spanish does not need to say that explicitly. The important point is what they did not do: they didn’t put a cast on him/her.

Because sin muletas means without crutches in a general sense.

When Spanish talks about doing something without a tool, aid, or item in general, it often leaves out the article:

• sin gafas = without glasses
• sin coche = without a car
• sin muletas = without crutches

If you said sin las muletas, it would usually mean without the specific crutches already mentioned or known in the conversation.

So here sin muletas is the natural general expression.
