Which metatarsal is commonly subject to trauma due to having a large tuberosity?

• A. First metatarsal
• B. Third metatarsal
• C. Fifth metatarsal
• D. Fourth metatarsal

Answer: (C)

The fifth metatarsal is commonly subjected to trauma due to its prominent tuberosity, located at its base. This tuberosity serves as an attachment point for ligaments and muscles, making it a site for stress during weight-bearing activities. The anatomy of the fifth metatarsal means that it is predisposed to injuries such as fractures, especially in sports or activities that involve lateral movements or twisting forces. This anatomical feature contributes to its vulnerability, particularly in cases of excessive force or awkward foot positioning.

In contrast, while the first metatarsal also has a prominent structure, it does not experience the same level of trauma as the fifth. The third and fourth metatarsals have less pronounced tuberosities and are therefore not as commonly associated with such trauma.
