Muscles of the Leg that Move the Foot and Toes

Muscles 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.

Ankle Joint

Ankle 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...

Pulse Assessment Sites

Pulse Assessment Sites

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...

Bones of the Lower Limb: Femur and Patella

Bones 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...

Bones of the Lower Limb: Tibia and Fibula

Bones 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...

Knee Joint

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

Summary

Pastern injuries cause lameness in performance horses. Understanding breed and activity links aids diagnosis, with soft tissue injuries being harder to diagnose but having a good prognosis for return to use.

Area of Science:

Equine Orthopedics
Veterinary Sports Medicine

Background:

Pastern region injuries are a frequent cause of lameness in performance horses.
Diagnosing pastern injuries requires considering breed and activity-specific predispositions.
Common differential diagnoses include osteoarthritis, osteochondrosis, fractures, infection, and soft tissue injuries.

Purpose of the Study:

To highlight the importance of breed- and activity-associated injuries in the pastern region for accurate diagnosis.
To differentiate the diagnostic and prognostic implications of soft tissue versus osseous injuries in the equine pastern.

Main Methods:

Review of common pastern region disorders in performance horses.
Analysis of diagnostic challenges and prognostic factors for different injury types.

Main Results:

Soft tissue injuries in the pastern are often challenging to diagnose.
Osseous (bone) injuries are generally easier to diagnose.
Horses with soft tissue injuries have a reasonable chance of returning to their intended use.
Osseous injuries have a good prognosis, particularly if arthrodesis (joint fusion) is a viable treatment option.

Conclusions:

Accurate diagnosis of equine pastern injuries relies on understanding breed and activity correlations.
Prognosis varies significantly between soft tissue and osseous injuries.
Arthrodesis can offer a favorable outcome for specific osseous pastern injuries.
