Bones of the Lower Limb: Femur and Patella01:16

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 Leg01:23

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...
Knee Joint01:23

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
This summary is machine-generated.

Crouch gait in spastic diplegic cerebral palsy (CP) can lead to knee extensor disruption (KED), hindering ambulation. Early diagnosis via gait analysis is crucial for managing this often-overlooked complication in CP patients.

Area of Science:

  • Neurology
  • Orthopedics
  • Biomechanical Engineering

Background:

  • Spastic diplegic cerebral palsy (CP) frequently presents with crouch gait, a challenging ambulatory dysfunction.
  • While CP is non-progressive, crouch gait can precipitate knee extensor disruption (KED), leading to ambulation decline.
  • KED diagnosis in the context of crouch gait is often missed, impacting patient management.

Observation:

  • A 28-year-old active woman with diplegic CP and severe crouch gait reported reduced walking speed and endurance.
  • The patient was referred for comprehensive gait analysis to investigate her functional decline.
  • Clinical observation highlighted gait patterns suggestive of KED.

Findings:

  • Gait analysis revealed kinematic indicators characteristic of knee extensor disruption.
  • Radiological imaging confirmed the presence of KED in the affected individual.
  • This case underscores the link between severe crouch gait and underlying KED.

Implications:

  • Highlights the importance of considering KED in ambulant CP patients with crouch gait.
  • Suggests gait analysis as a valuable diagnostic tool for identifying KED.
  • Emphasizes the need for timely diagnosis and intervention to preserve ambulation in CP.
