Summary
Peroneal tendon longitudinal tears often occur with ankle sprains due to impingement. Cadaver studies identified specific plantar flexion angles causing these injuries, leading to better surgical repair outcomes.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Anatomy
Background:
- Longitudinal tears of the peroneal tendon can cause persistent lateral ankle pain and swelling after initial injury.
- Retrospective clinical observations noted these symptoms in athletes with lateral ankle sprains.
Purpose of the Study:
- To elucidate the precise injury mechanism of peroneal tendon longitudinal tears.
- To correlate clinical findings with biomechanical factors in cadaveric models.
Main Methods:
- Retrospective review of 8 athletes with peroneal tendon tears and ankle sprains.
- Cadaveric dissection and biomechanical testing of 15 lower extremities.
Main Results:
- Cadaver studies revealed tears occur between 15-25 degrees plantar flexion due to impingement of peroneus longus and brevis tendons.
- Clinical cases showed persistent retrofibular pain and popping despite stable ankles after initial sprain management.
Conclusions:
- Impingement of the peroneal tendons against the fibula during plantar flexion is a key mechanism for longitudinal tears.
- Surgical repair of these tears yielded excellent long-term results.

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...
01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:23Muscles that Move the Leg
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

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.
