- What it is
- A common tendon passes under the extensor retinacula in front of the ankle and fans into four slips on the dorsum of the foot, forming the dorsal (extensor) expansions of toes 2-5.
- Function
- Lifts (extends) the lateral four toes.
- Size
- Common tendon about 5 mm; slips about 2 mm wide.
- Clinical note
- The slips stand out under the skin of the dorsum when the toes are raised - a quick test of the deep fibular nerve.
