    Summary

    This study examines arthrogryposis, a congenital joint disorder, in two children. Findings suggest connective tissue abnormalities may play a significant role in its development.

    Area of Science:

    • Pediatrics
    • Genetics
    • Neurology

    Background:

    • Arthrogryposis multiplex congenita (AMC) is a heterogeneous group of non-progressive congenital disorders characterized by multiple joint contractures.
    • Diagnostic criteria for AMC include joint limitations present at birth, absence of progressive neurological involvement, and evident amyotrophy.

    Observation:

    • Two cases of arthrogryposis in children aged 7.5 and 13 years are presented.
    • The cases were diagnosed using Fisher's criteria, emphasizing congenital joint limitations across multiple regions.

    Findings:

    • Literature review indicates heterogeneity in myopathic arthrogryposis cases, with variable histopathological findings and insufficient histoenzymological studies.
    • Neurological anomalies are often associated with arthrogryposis but are not consistently present or solely explanatory.
    • Connective tissue changes, particularly excessive proliferation of connective tissue and excessive synthesis of connective proteins, are highlighted as potentially underestimated factors.

    Implications:

    • Further research into the role of connective tissue abnormalities in arthrogryposis pathogenesis is warranted.
    • Understanding the interplay between neurological and connective tissue factors is crucial for accurate diagnosis and potential therapeutic strategies.
    • This study contributes to the ongoing debate on the etiopathogenesis of arthrogryposis, emphasizing a multifactorial etiology.
