Ankle Joint01:10

Ankle Joint

3.4K
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...

Bones of the Lower Limb: Tibia and Fibula

14.3K
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...

Bones of the Lower Limb: Femur and Patella

9.0K
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...

Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

4.6K
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....

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Anatomy

Background:

  • Total talar dislocations are infrequent, accounting for 3.4% of major talar injuries.
  • Common complications include osteomyelitis and avascular necrosis.
  • Existing literature is limited to case reports and small series.

Purpose of the Study:

  • To review the anatomy and blood supply of the talus.
  • To discuss the mechanism of injury, clinical presentation, and management of total talar dislocations.
  • To outline potential complications associated with these injuries.

Main Methods:

  • Literature review of total talar dislocations.
  • Analysis of anatomical structures and vascular supply to the talus.
  • Synthesis of information on injury mechanisms, diagnosis, and treatment strategies.

Main Results:

  • Detailed description of talar anatomy and its critical blood supply.
  • Discussion of various injury mechanisms leading to total talar dislocation.
  • Overview of current treatment options and their associated outcomes.

Conclusions:

  • Total talar dislocations require a thorough understanding of talar anatomy and vascularity.
  • Early diagnosis and appropriate management are crucial to minimize complications.
  • Further research with larger cohorts is needed to optimize treatment protocols.
