Final answer:
Residual cavus after surgical clubfoot correction is typically caused by an imbalance in muscle strength between the muscles on the top and bottom of the foot, leading to a high-arched position. Close adherence to postoperative instructions is essential for preventing this complication.
Step-by-step explanation:
Residual cavus after surgical clubfoot correction is often caused by an imbalance in muscle strength, where the muscles on the top of the foot are stronger than those on the bottom. This imbalance can pull the foot into a high-arched position. Treatment for clubfoot typically begins with non-surgical approaches such as gentle stretching and corrective casting, followed by the application of a holding cast. In severe cases, surgery might be necessary. Postoperative care, including special exercises, the use of braces, and special shoes, is crucial to prevent relapse and ensure the best outcome for the child. It is essential for parents to closely monitor and adhere to postoperative instructions to minimize the likelihood of complications such as residual cavus.
