Final answer:
The statement is true; most children with bilateral clubfeet can eventually walk without major difficulties, and serial casting is usually effective. Surgery may be required if casting fails.
Step-by-step explanation:
Most children with bilateral clubfeet are eventually able to walk without significant difficulty, and the assertion that most cases can be corrected without the need for prosthetic devices is true. Serial casting, with weekly adjustments, is often successful. In instances where casting does not provide the desired results, surgical intervention may become necessary. However, with early treatment, the majority of children can expect to lead normal, active lives. Notably, special shoes and braces, along with regular exercises, will support the treatment post cast removal, and compliance with these elements is crucial to minimize the risk of relapse.
