Summary
Ultrasound imaging effectively diagnoses posterior tibial tendon disorders, including chronic tendinopathy and ruptures. This method is crucial for evaluating medial ankle pain and instability.
Area of Science:
- Orthopedics
- Radiology
- Musculoskeletal Imaging
Background:
- The tibialis posterior tendon is vital for ankle stability and function.
- Disorders of this tendon can lead to significant medial ankle pain and functional limitations.
Purpose of the Study:
- To outline the sonographic assessment of the tibialis posterior tendon.
- To detail common disorders affecting the tibialis posterior tendon.
Main Methods:
- Utilizing high-frequency, linear-array transducers for sonography.
- Employing specific scanning planes: transverse retromalleolar, longitudinal retromalleolar, and distal longitudinal views.
- Incorporating dynamic sonographic studies to assess tendon function and stability.
Main Results:
- Sonography is a key tool for investigating tibialis posterior tendon pathologies.
- Common lesions include chronic tendinopathy with progressive rupture, often presenting as a "chewing gum" lesion.
- Specific patient demographics, such as overweight women over 50 with valgus flat feet, are more prone to certain lesions.
Conclusions:
- Sonography is essential for diagnosing a range of tibialis posterior tendon disorders.
- Accurate sonographic evaluation aids in managing medial ankle pain and instability.
- Dynamic ultrasound maneuvers are critical for assessing functional deficits and instability.

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.

01:10Bones of the Lower Limb: Tibia and Fibula
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...
01:23Muscles 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...

01:10Ankle 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...
01:20Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
01:15Veins of Lower Limbs
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the knee,...
