Which shoe modification is commonly used after first metatarsophalangeal joint arthrodesis?

• A. Metatarsal pad
• B. Metatarsal bar
• C. Rockers bottom
• D. Arch support

Answer: (B)

After first MTP joint arthrodesis, the big toe cannot dorsiflex during push-off, which tends to shift more load onto the forefoot and, specifically, the first metatarsal head. The goal of a shoe modification here is to redistribute that load and reduce peak pressure under the forefoot so the fused joint is protected and gait remains comfortable. A metatarsal bar sits proximal to the metatarsal heads and shifts pressure away from the forefoot toward the midfoot and hindfoot during stance. This redistribution lowers plantar pressures at the first met head, helping prevent forefoot pain and transfer lesions and aiding a smoother rollover without requiring motion at the fused joint. Metatarsal pads can help but are less effective for broad forefoot offloading; a rocker bottom facilitates rollover but doesn’t target load avoidance at the first met head as directly; arch supports don’t address forefoot pressure in this context.
