Insights

This study establishes standard intrauterine hip development values using ultrasound, revealing that fetal posture influences hip development. These findings aid in interpreting hip joints in premature infants.

Area of Science:

  • Orthopaedics
  • Fetal Medicine
  • Medical Imaging

Background:

  • Congenital dislocation of the hip (CDH) etiology and pathogenesis remain incompletely understood.
  • High-resolution ultrasound technology enables in vivo investigation of the fetal hip joint.

Purpose of the Study:

  • To establish standard values for intrauterine hip development using ultrasound.
  • To investigate the influence of intrauterine conditions on fetal hip development.

Main Methods:

  • Ultrasound examination of 146 fetuses (141 pregnancies) from 20 weeks gestation to birth.
  • Establishment of standard intrauterine hip development values and Alpha-angles.

Main Results:

  • Standard values for intrauterine hip development were established from 20 weeks gestation to birth.
  • Prenatal Alpha-angles, averaging 59.7 (SD 8.9) at term, suggest intrauterine posture influences hip development.
  • Achieved Alpha-angles align with Graf's standards for postnatal hip development.

Conclusions:

  • Established standard intrauterine hip development values are crucial for interpreting fetal hip joints.
  • Findings provide a basis for understanding hip development in premature infants and potentially in early CDH detection.

Ultrasonography01:17

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...
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...
