Insights

Developmental dysplasia of the hip (DDH) screening improved with sonography. This diagnostic tool reduced both the incidence and treatment duration for DDH in infants.

Area of Science:

  • Pediatric Orthopedics
  • Diagnostic Imaging
  • Public Health

Background:

  • Developmental dysplasia of the hip (DDH) poses a significant challenge in pediatric orthopedics.
  • Understanding its prevalence, risk factors, and treatment is crucial for early intervention.
  • The introduction of sonographic examination in 1993 marked a potential shift in DDH management.

Purpose of the Study:

  • To evaluate the impact of sonographic examination on the prevalence and treatment of DDH.
  • To analyze changes in DDH incidence and treatment duration before and after the adoption of sonography.
  • To identify and confirm risk factors associated with DDH, particularly late-onset cases.

Main Methods:

  • A retrospective analysis of 1,469 infants followed for clinical findings or risk factors related to DDH.
  • Comparison of data from infants examined via X-ray versus sonography.
  • Statistical analysis to assess changes in prevalence, risk factors, and treatment duration post-sonography introduction.

Main Results:

  • Overall DDH prevalence was 1.14%, with 0.92% in neonates and 0.22% as late DDH.
  • Introduction of sonography correlated with a decrease in newborn DDH (1.06% to 0.77%) and a significant reduction in treatment duration (6.2 to 4.2 months).
  • Confirmed risk factors included maternal pre-pregnancy weight and weight gain during the last trimester for late DDH cases.

Conclusions:

  • Sonographic examination has demonstrably reduced the treatment rate and duration for DDH.
  • Early detection through sonography improves management outcomes for infants with DDH.
  • Continued research into risk factors can further refine screening and treatment protocols.

Sex-linked Disorders01:43

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

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...
