Peroneus (Fibularis) longus
Origin: Proximal 2/3 of fibula and lateral condyle of tibiaInsertion: 1st Cuneiform and base of 1st MetatarsalsAction: Plantarflexion and Eversion
The peroneus longus muscle, also called the fibularis longus muscle, is a long, thin muscle located on the lateral (outer) side of the leg. It runs from the head of the fibula (the smaller bone in the lower leg) down to the first metatarsal bone of the foot.
Function:
The peroneus longus muscle is responsible for several important functions including:
1. Plantarflexion: The muscle plays a role in plantarflexion, which is the movement of the foot downward, towards the ground.
2. Eversion: It also functions to evert the foot, or move it outward away from the midline.
3. Support: The peroneus longus muscle is also involved in supporting the arch of the foot, as it attaches to the plantar structures of the foot.
4. Stabilize: In addition, the muscle helps to stabilize the ankle joint during movements such as walking, running or jumping.
Injuries:
Injuries to the peroneus longus muscle can occur due to overuse, acute trauma or repetitive stress. Common injuries include peroneal tendonitis, strain or tears of the muscle fibers, and ankle sprains. Symptoms of an injury to the peroneus longus muscle can include pain, swelling, bruising, weakness or decreased range of motion.
Treatment:
Treatment for peroneus longus muscle injuries may include rest, ice, compression, and elevation (R.I.C.E), physical therapy, or surgery in severe cases. It is important to seek a consultation with a healthcare professional if you experience any persistent pain or other symptoms.
