What is the most common complication of clubfoot casting?

• A. Skin breakdown
• B. Rocker-bottom deformity
• C. Recurrence of foot deformity
• D. Painful callus

Answer: (B)

The main idea here is recognizing the most characteristic mechanical complication that can arise during clubfoot casting. A rocker-bottom deformity signifies a collapse of the midfoot into a plantarflexed, arch-less configuration as the casts fail to fully correct the cavus and midfoot instability. This pattern reflects incomplete or relapsed correction of the deformity during casting, especially when the sequence of abduction and dorsiflexion doesn’t achieve a stable arch and midfoot alignment. Because it represents a distinct, weight-bearing change in the foot’s structure after casting, it’s the complication clinicians most readily identify as a casting-related failure. Skin issues like irritation or breakdown, and weight-bearing changes such as a painful callus, can occur with casting but don’t define the common mechanical failure pattern as clearly. Recurrence of the deformity is also a concern, but rocker-bottom describes the specific flattening and rounding of the foot that signals a casting failure pattern that often requires adjustment in treatment strategy.
