Insights

Children with developmental dysplasia of the hip (DDH) do not typically experience a significant delay in walking. This study found that while walking age was slightly later, it remained within normal developmental limits for all affected children.

Area of Science:

  • Pediatrics
  • Orthopedics
  • Developmental Biology

Background:

  • Developmental dysplasia of the hip (DDH) is a condition affecting hip joint development.
  • A common clinical assumption is that DDH leads to delayed ambulation in children.

Purpose of the Study:

  • To investigate the actual age of walking in children diagnosed with DDH.
  • To compare the walking age of children with DDH against a control group.

Main Methods:

  • Retrospective review of 86 children with established DDH.
  • Comparison with an age- and sex-matched control cohort.
  • Analysis of the median age of walking in both groups.

Main Results:

  • Children with DDH walked at a median age of 1 month later than controls.
  • This difference was not clinically significant.
  • All children in the DDH group achieved walking within established normal developmental timelines.

Conclusions:

  • Developmental dysplasia of the hip does not appear to be a cause of significant delay in walking.
  • Clinical practice should not assume late walking based solely on a DDH diagnosis.

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...

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...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
