Summary
Variations in peroneus longus tendon insertion were observed in cadaver feet. Two new lateral insertion bands were identified, challenging traditional anatomical descriptions.
Area of Science:
- Anatomy
- Biomechanics
- Orthopedics
Background:
- The peroneus longus tendon traditionally inserts onto the plantar surface of the medial cuneiform and the base of the 1st metatarsal.
- This insertion is considered a primary factor in the plantarflexed first ray, a characteristic of cavus foot deformities.
Purpose of the Study:
- To investigate and document the anatomical variations in the insertion of the peroneus longus tendon.
- To identify the presence of sesamoid bones within the tendon and describe any atypical insertion patterns.
Main Methods:
- Dissection and examination of the peroneus longus tendon insertion in 26 adult cadaver feet.
- Detailed recording of insertional points, presence of sesamoid bones, and any observed anatomical variations.
Main Results:
- The majority of feet showed the main insertion at the base of the 1st metatarsal and medial cuneiform.
- Significant variations were observed, including the presence of a sesamoid bone under the cuboid in 16 feet.
- Twelve of these feet with sesamoid bones also exhibited additional lateral insertion bands.
Conclusions:
- The study identified considerable variations in the insertion of the peroneus longus tendon.
- Two novel lateral insertion bands of the peroneus longus tendon are described, expanding current anatomical knowledge.

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:28Muscles of the Leg that Move the Foot and Toes
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
