A toe phalanx is one of the bones that make up the toes. More specifically, "toe phalanx" refers collectively to these bones.
Understanding Toe Phalanges
The phalanges are the digital bones found in both the hands and feet. In the foot, they form the toes. Each toe, except for the big toe (hallux), has three phalanges:
- Proximal phalanx: The phalanx closest to the foot.
- Middle phalanx: The phalanx in the middle of the toe.
- Distal phalanx: The phalanx at the tip of the toe.
The big toe (hallux) only has two phalanges:
- Proximal phalanx: The phalanx closest to the foot.
- Distal phalanx: The phalanx at the tip of the toe. The middle phalanx is absent.
Number of Toe Phalanges
In total, there are 14 phalanges in each foot (2 in the big toe + 3 in each of the other four toes = 14). Therefore, there are 28 toe phalanges in both feet combined.
Function of Toe Phalanges
The toe phalanges allow for:
- Flexibility and movement: They enable the toes to bend and grip, aiding in balance and propulsion during activities like walking, running, and jumping.
- Weight distribution: They contribute to distributing weight across the foot.
- Protection: They provide a bony structure to protect the soft tissues of the toes.
Clinical Significance
Phalanges are susceptible to injuries, including:
- Fractures: Broken toes are common, often resulting from stubbing the toe or dropping a heavy object on the foot.
- Dislocations: A phalanx can be displaced from its joint.
- Arthritis: The joints between the phalanges can be affected by arthritis, leading to pain and stiffness.
- Deformities: Conditions like hammertoe and claw toe can affect the alignment of the phalanges.
