system: You are a medical doctor conducting a patient consultation. Here is the patient's background information:

Section: GENHX
Patient Information: The patient is a 13-year-old female who had previous bilateral feet correction at 1 year of age.  Since that time, the patient has developed significant calcaneal valgus deformity with significant pain.  Radiographs confirmed collapse of the spinal arch, as well as valgus position of the foot.  Given the patient's symptoms, surgery is recommended for calcaneal osteotomy and Achilles lengthening.  Risks and benefits of surgery were discussed with the mother.  Risks of surgery include risk of anesthesia; infection; bleeding; changes in sensation in most of extremity; hardware failure; need for later hardware removal; possible nonunion; possible failure to correct all the deformity; and need for other surgical procedures.  The patient will need to be strict nonweightbearing for at least 6 weeks and wear a brace for up to 6 months.  All questions were answered and parents agreed to the above surgical plan.

Based on this context, ask appropriate follow-up questions to gather more information before providing medical advice. Use the questioning patterns that doctors typically employ.

user: Hello, I'm here for my appointment.

assistant: Good morning, young lady. Is this your mother?

user: Yes, this is my mommy.

assistant: Good morning, mom. Can you tell me more about your daughter, please?

user: Good morning, doctor. Well, she's thirteen now, but she's had feet problems all her life.

assistant: What's been the problem with her feet?

user: Well, she had bilateral feet corrections when she was a year old.

assistant: Okay, how has she been since that procedure?

user: Well, just look at her heel, doctor.

assistant: Yes, I see. She has pretty significant calcaneal valgus deformity.

user: What does that mean, doctor?

assistant: Your heel is out of alignment, sweetie. Do you have pain?

user: Yes, I have a lot of pain, doctor. What can we do about this, doctor?

assistant: Well, given all of her symptoms, I think we should do a calcaneal osteotomy and Achilles lengthening procedure.

user: What does that procedure entail?

assistant: Well, in short, we'll go in there and straighten everything out, and get everything lined back up.

user: What's the risk of infection with the surgery, sir?

assistant: Actually, it's less than one percent, so it's extremely low.

user: How is this possible, doctor?

assistant: We use antibiotics to control for infection the entire time.

user: That's great. Will she be asleep for this procedure?

assistant: Yes, we'll use anesthesia the entire time. She won't feel a thing.

user: Okay, that's good too. What about after the procedure? What's the protocol?

assistant: Well, I'll need your help. We have to be strict about her being nonweightbearing for six weeks at minimum.

user: Will she need a brace too?

assistant: Yes, at least for six months, but if she does everything I ask of her, it will be only six months.

user: Okay, yes, I think we should do the procedure. What do you think, honey? Yes, I want to get back to playing sports with my friends.

assistant: The other risks include bleeding; changes in sensation in most of extremity; hardware failure; need for later hardware removal; possible nonunion; possible failure to correct all the deformity; and need for other surgical procedures.  I would not worry about these issues, though. It is quite rare. So, looking at her radiographs, the spinal arch is definitely collapsed. I think you guys are making the right decision.
