A "met head" typically refers to the head of a metatarsal bone in the foot. The metatarsal heads are the rounded ends of the long bones in your forefoot, located just before your toes.
Understanding Metatarsal Heads
- Location: They're found in the forefoot, connecting the metatarsal bones to the proximal phalanges (the first bones of your toes).
- Anatomy: Each metatarsal head is covered with cartilage. This cartilage provides a smooth, low-friction surface that allows the metatarsals to articulate (move) with the phalanges during walking, running, and other foot movements. The cartilage extends from the plantar (bottom) to the dorsal (top) surfaces of the metatarsal head.
- Function: They are crucial for weight-bearing and distributing pressure across the forefoot during movement.
- Range of Motion: The articulation at the metatarsal head allows for significant range of motion – typically up to 75 degrees of extension (bending upwards) and 40 degrees of flexion (bending downwards).
- Common Issues: Pain in the metatarsal heads (metatarsalgia) is a common foot problem. This can be caused by factors such as high-impact activities, improper footwear, foot deformities (like bunions or hammertoes), or nerve compression (Morton's neuroma).
The Importance of Cartilage
The cartilage covering the metatarsal heads is essential for proper foot function. It:
- Reduces friction during movement.
- Absorbs shock.
- Allows for smooth articulation between the metatarsals and phalanges.
Damage or deterioration of this cartilage can lead to pain, stiffness, and limited range of motion in the forefoot.
In Summary
The "met head" is the head of a metatarsal bone in your foot, a critical weight-bearing structure covered in cartilage that allows for smooth and flexible movement of your toes. Problems in this area can lead to forefoot pain and dysfunction.
