Summary
Lateral intersection syndrome, an overuse condition of the foot, involves the peroneus longus and brevis tendons. This study established baseline anatomical measurements for this underreported pathology.
Area of Science:
- Anatomy
- Orthopedics
- Sports Medicine
Background:
- Lateral intersection syndrome, affecting the peroneus longus and brevis tendons, is an underreported overuse condition.
- Similar intersection syndromes are documented in the wrist and medial foot/ankle.
Purpose of the Study:
- To establish baseline anatomical measurements relevant to lateral intersection syndrome.
- To provide foundational data for further research and clinical recognition.
Main Methods:
- Dissection of eight fresh-frozen cadaveric lower limbs (4 matched pairs).
- Measurement of key lateral foot structures: plantar fascia width, peroneus brevis width, distance between peroneus brevis and plantar fascia, and distance between cuboid groove and fifth metatarsal.
Main Results:
- Average plantar fascial width was 4.99 mm.
- Average peroneus brevis width was 6.64 mm.
- Right-sided specimens exhibited larger measurements than left-sided specimens.
Conclusions:
- This cadaveric study provides essential anatomical data for understanding lateral intersection syndrome.
- Further research and increased clinical awareness are needed for this condition.

1.9K
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...

01:10Bones of the Lower Limb: Tibia and Fibula
5.4K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

01:16Bones of the Lower Limb: Femur and Patella
3.1K
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...

01:28Muscles of the Leg that Move the Foot and Toes
2.5K
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....

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

01:07Development of the Limb Synovial Joints
1.6K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
