Insights

Bone mineral density in children with cerebral palsy (CP) is significantly lower, especially in those with severe hip instability or higher Gross Motor Function Classification System (GMFCS) levels. This impacts hip joint health.

Area of Science:

  • Orthopedics
  • Pediatric Radiology
  • Neurology

Background:

  • Cerebral palsy (CP) can affect bone development and density.
  • Hip joint complications are common in children with CP.
  • Assessing bone mineral density is crucial for managing CP-related orthopedic issues.

Purpose of the Study:

  • To evaluate hip joint bone mineral density in pediatric patients with cerebral palsy (CP).
  • To determine the correlation between bone density, hip instability, and motor function in CP.
  • To identify factors influencing bone attenuation in the hip joint of children with CP.

Main Methods:

  • Computed tomography (CT) scans of the hip joint were analyzed in 126 children with CP and 86 controls.
  • Bone attenuation (Hounsfield units) of the acetabulum and femur was measured.
  • Adjustments were made for hip instability (migration percentage) and Gross Motor Function Classification System (GMFCS) levels.

Main Results:

  • Children with CP exhibited significantly lower bone attenuation in the acetabulum and femur compared to controls.
  • Lower bone attenuation was strongly associated with higher GMFCS levels (IV and V) and increased hip migration percentage (>37%).
  • Bone attenuation decreased notably with increasing severity of hip instability and motor impairment.

Conclusions:

  • Hip joint bone mineral density is significantly reduced in children with cerebral palsy.
  • Both the severity of hip instability and the GMFCS level are critical determinants of bone attenuation in the hip.
  • These findings highlight the need for targeted interventions to address bone health in pediatric CP patients.

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...

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...

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
