Swedish metacarpophalangeal standards compared with previously published norms
1Department of Radiology, Astrid Lindgren Children's Hospital, Stockholm, Sweden.
Insights
This study established Swedish metacarpophalangeal length standards for children. Local standards are recommended for accurate skeletal dysplasia assessment due to observed deviations from previous norms.
Area of Science:
- Pediatric orthopedics
- Medical imaging analysis
Background:
- Metacarpophalangeal lengths are crucial for diagnosing skeletal dysplasias and malformation syndromes.
- Pattern profiles derived from these lengths aid in clinical assessment.
Purpose of the Study:
- To establish normative standards for metacarpophalangeal lengths in a healthy Swedish pediatric population.
- To compare these newly established Swedish standards with existing international norms.
Main Methods:
- Longitudinal study of healthy Swedish children from 1 month to 18 years.
- Radiographic measurement of hand tubular bone lengths, including diaphyseal lengths.
- Data collection involved conventional measurements and isolated diaphyseal length recordings.
Main Results:
- Presentation of mean and standard deviation values for metacarpophalangeal lengths, stratified by gender and age.
- Detailed data for Swedish children's skeletal development is provided.
Conclusions:
- While Swedish standards show reasonable correlation with previous norms, significant deviations were observed.
- The study recommends utilizing local, population-specific standards for improved diagnostic accuracy in skeletal assessments.
Purpose:
Metacarpophalangeal lengths are used to create pattern profiles that are useful for assessment of skeletal dysplasias and malformation syndromes. The purpose of this study was to establish Swedish standards and compare them with previously published norms.
Material And Methods:
A group of healthy Swedish children was followed longitudinally from the age of 1 month to 18 years. The length of the tubular bones of the hand was measured on radiographs. In addition to the conventional measurements including epiphyses, diaphyseal lengths alone were recorded.
Results:
Means and standard deviations of the metacarpophalangeal lengths are presented by gender and age.
Conclusion:
In spite of reasonably good correlation to previously published norms, demonstrated deviations encourage us to recommend the use of local standards whenever available.
