Insights

Children's gluteal muscle contracture (GMC) significantly impacts skeleton development, causing pelvis obliquity and other skeletal changes. The iliac hyperdense line on pelvic X-rays may be a characteristic sign of GMC.

Area of Science:

  • Pediatric Orthopedics
  • Skeletal Development
  • Biomechanical Analysis

Context:

  • Gluteal muscle contracture (GMC) in children is a condition that can affect musculoskeletal development.
  • Understanding the skeletal sequelae of GMC is crucial for timely diagnosis and intervention.

Purpose:

  • To investigate the effects of pediatric gluteal muscle contracture (GMC) on skeletal development.
  • To identify characteristic radiographic findings associated with GMC.

Summary:

  • Analysis of pelvic X-rays and CT scans from 368 children with GMC and 200 controls revealed significant differences in pelvic obliquity, iliac hyperdense lines, centre-edge (CE) angle, and neck shaft angle between groups.
  • Pre-operative findings in the GMC group showed significant deviations (P < 0.01) compared to controls, with most normalizing post-operatively (P > 0.01).

Impact:

  • Pediatric GMC can lead to developmental abnormalities including pelvis obliquity, coxa valga, and leg length discrepancies.
  • The presence of an iliac hyperdense line on pelvic plain films is likely a characteristic indicator of gluteal muscle contracture in children.

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...

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...

Introduction to the Skeletal System

The skeletal system is the central framework of the body, consisting of different connective tissues: bones, cartilage, tendons, and ligaments.
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...
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...
Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
