Final answer:
The frequency of cast changes for an infant with clubfoot is typically weekly for several weeks. After any necessary surgery, the cast stays for 6 to 8 weeks, followed by part-time bracing for up to four years.
Step-by-step explanation:
The student has asked about the frequency of cast changes needed for an infant with talipes equinovarus, also known as clubfoot. Clubfoot treatment ideally should start within the first two weeks after birth and involves a process where the infant's foot is gently stretched and then held in place with a cast.
This corrective casting and stretching process is typically repeated weekly for several weeks. In severe cases, after necessary surgery, the foot may remain in a cast for 6 to 8 weeks. After treatment, either surgical or nonsurgical, a brace must be worn part-time for up to four years, along with special exercises and shoes. Parents should closely monitor the child and follow postoperative instructions to reduce the risk of a relapse.
