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...

Muscles that Move the Thigh

Muscles that Move the Thigh

The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar fascia...

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...

Area of Science:

Orthopedics
Radiology
Sports Medicine

Background:

Femoroacetabular impingement (FAI) is a significant cause of early-onset hip osteoarthritis.
FAI results from abnormal morphology of the proximal femur or acetabulum.
Repetitive abutment leads to labral and cartilage damage, progressing to osteoarthritis.

Purpose of the Study:

To highlight the role of FAI in hip osteoarthritis.
To explain the pathomechanics of FAI.
To emphasize the diagnostic capabilities of MRI in FAI.

Main Methods:

Review of literature on FAI and hip osteoarthritis.
Analysis of the diagnostic accuracy of Magnetic Resonance Imaging (MRI).
Correlation of anatomical variations with FAI and subsequent joint damage.

Main Results:

FAI, stemming from morphological abnormalities, is a primary driver of hip osteoarthritis.
MRI accurately identifies labral lesions, cartilage damage, and subtle anatomical variations.
The repetitive trauma associated with FAI initiates a cascade towards osteoarthritis.

Conclusions:

FAI is a key precursor to hip osteoarthritis.
MRI is a crucial non-invasive tool for diagnosing FAI and associated pathologies.
Understanding FAI's anatomical basis is vital for early detection and management.
