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...

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...

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.

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...

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...

Muscles that Move the Leg

Muscles 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...

Summary

This summary is machine-generated.

Complete neurovascular assessment is crucial for all limb injuries. A missed assessment in a young patient with patellar dislocation led to foot drop, highlighting the need for thorough emergency department evaluations.

Area of Science:

Orthopedics
Emergency Medicine
Neurology

Background:

Limb injuries require thorough neurovascular assessment, often overlooked in emergency settings.
Delayed diagnosis of neurovascular compromise can impede recovery and treatment.
Prompt identification enables timely orthopedic intervention and management.

Observation:

A young patient with patellar dislocation experienced a missed neurovascular assessment in the emergency department.
This oversight resulted in the development of foot drop and sensory numbness.
The symptoms were localized to the distribution of the deep peroneal nerve.

Findings:

The case represents the first reported instance of foot drop associated with patellar dislocation.
Conservative treatment led to complete recovery of neurovascular function within three and a half months.
This highlights the potential for significant neurovascular sequelae from seemingly isolated injuries.

Implications:

Emphasizes the critical importance of routine neurovascular assessments in all limb injury evaluations.
Suggests that patellar dislocations may carry a higher risk of neurovascular injury than previously recognized.
Underscores the need for enhanced training and protocols in emergency departments to prevent missed diagnoses.
