Insights

This study details the timing of hip ossification centers and growth plate closure in healthy individuals aged 3-21. Findings provide crucial data for assessing hip development and potential pathologies.

Area of Science:

  • Orthopedics
  • Radiology
  • Human Anatomy

Context:

  • The development of the hip joint involves complex ossification processes.
  • Accurate timing of these events is essential for diagnosing developmental abnormalities.

Purpose:

  • To establish normative data for the appearance of secondary ossification centers and closure of growth plates in the acetabulum and proximal femur.
  • To provide a reference for evaluating hip joint development in pediatric and adolescent populations.

Summary:

  • Utilized MRI scans from 45 healthy patients (ages 3-21) to map the timing of ossification for the triradiate cartilage, acetabular roof, subcapital, major trochanter, and minor trochanter growth cartilages.
  • Detailed sex-specific timelines for the appearance of major and minor trochanter ossification centers and complete ossification of key hip growth plates.
  • Documented the appearance of secondary ossification centers for the pubic bone and acetabular roof, noting variations between sexes and age ranges.

Impact:

  • Enhances understanding of normal hip joint development and maturation.
  • Facilitates more accurate assessment and diagnosis of hip pathologies in children and adolescents.
  • Provides valuable reference data for orthopedic surgeons, radiologists, and researchers.

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
Ankle Joint01:10

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...
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...
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...
Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...
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...
