Mi vecina fue a urgencias con dolor en el pie y salió con yeso y muletas.

Vecina is the feminine form of vecino, so it means female neighbor. The sentence is talking about a woman.

• mi vecino = my male neighbor
• mi vecina = my female neighbor

Notice that mi does not change for masculine or feminine singular nouns.

Fue is the preterite form of ir for él/ella/usted. Here it means she went.

• ir = to go
• ella fue = she went

The preterite is used because this is a completed action in the past: she went to urgent care / the ER.

Also, fue can also come from ser, but here the meaning clearly comes from ir because it is followed by a urgencias.

In Spain, ir a urgencias means to go to the ER / emergency room / urgent care emergency department.

Urgencias is very commonly used in Spain to refer to emergency medical services or the emergency department of a hospital.

So:

• Fue a urgencias = She went to the ER / emergency department

This is a very natural Spain Spanish expression.

Because in Spanish, urgencias is the normal noun used for emergency services or the emergency department. Even though English often uses a singular expression like the ER, Spanish commonly uses this plural form.

You do not need to translate it word-for-word. Just learn ir a urgencias as a set phrase.

In Spain, ir a urgencias without an article is a very common fixed expression.

You can sometimes hear ir a las urgencias del hospital when someone is being more specific, but in everyday speech, a urgencias is extremely natural.

So this is best learned as a standard expression:

• ir a urgencias

Spanish often uses the definite article with body parts when it is already obvious whose body part is meant.

So instead of saying:

• su pie = her foot

Spanish often prefers:

• el pie = the foot

Because the owner is clear from the context, en el pie sounds more natural.

This is very common in Spanish:

• Me duele la cabeza = My head hurts
• Se rompió el brazo = He/She broke his/her arm

Dolor en el pie means pain in the foot, focusing on the location of the pain.

That is the most natural wording here.

Dolor del pie can sometimes mean foot pain in a more general or descriptive way, but dolor en el pie fits this situation better because it describes where she was feeling pain when she went to the hospital.

Literally, it means she left with a cast and crutches.

The idea is:

• she went in with foot pain
• she came out wearing or having a cast and crutches

So salir con here shows the result of the visit: she ended up with those medical aids.

Spanish often leaves out the article after con when talking about something in a general way, especially when describing someone’s condition, appearance, or what they ended up with.

So:

• salió con yeso y muletas sounds natural and idiomatic

If you say:

• salió con un yeso y unas muletas

that is also grammatically correct, but it sounds a bit more specific or countable, as if you are focusing on the actual items themselves.

In everyday narration, the version without articles is very natural.

Yes. Yeso literally refers to gypsum/plaster, but in medical context it commonly means a cast.

So here:

• salió con yeso = she came out with a cast

In Spain, you may also hear escayola for a plaster cast.

Muletas means crutches.

The singular is:

• muleta = crutch

The plural is used here because people normally use two crutches:

• con muletas = with crutches

Because it is another completed past action in the story.

The sentence gives a sequence of finished events:

• fue a urgencias
• salió con yeso y muletas

This is exactly the kind of situation where Spanish uses the preterite: completed actions that move the story forward.

Not naturally, if you want this same meaning.

The sentence tells a completed chain of events, so the preterite is the right choice:

• fue
• salió

If you used the imperfect, it would sound like background information, repeated action, or an unfinished situation, which is not the main point here.

For example, iba a urgencias would suggest she was going to the ER or used to go, not a single completed visit.

Not necessarily. Vecina can mean a female neighbor in general, not only the person in the apartment or house immediately next to yours.

Depending on context, it can mean:

• next-door neighbor
• someone living nearby
• someone in the same building or neighborhood

Most of it would be understood everywhere, but a urgencias is especially typical of Spain.

In many parts of Latin America, people might be more likely to say things like:

• a emergencias
• a la sala de emergencias
• al hospital

But yeso and muletas are widely understood. The main regional point here is urgencias, which is very Spain-like.
