Summary

Femoral neck torsion develops physiologically from birth to skeletal maturity. Pathological decreases in this antetorsion angle are clinically significant for hip and knee issues, while increases are less important.

Area of Science:

  • Orthopedics
  • Developmental Biology
  • Radiology

Background:

  • Femoral neck torsion is a crucial developmental parameter affecting hip biomechanics.
  • Understanding normal torsion progression is essential for identifying pathological deviations.

Purpose of the Study:

  • To detail the physiological development of femoral neck torsion.
  • To outline relevant diagnostic methods for torsion abnormalities.
  • To clarify the clinical significance of altered antetorsion angles.

Main Methods:

  • Description of physiological torsion development from birth to skeletal maturity.
  • Review of diagnostic procedures including clinical examination, X-ray, and tomography.
  • Pathogenetic analysis correlating torsion with hip and knee symptoms.

Main Results:

  • Normal femoral neck antetorsion decreases from approximately 35 degrees at birth to 15 degrees at skeletal maturity.
  • Decreased antetorsion angle is identified as the most clinically relevant pathological finding.
  • Historically overestimated significance of increased antetorsion angle is highlighted.

Conclusions:

  • The study provides a comprehensive overview of femoral neck torsion development and diagnosis.
  • Clinical relevance is emphasized for decreased antetorsion, impacting hip and knee joint health.
  • Accurate assessment of femoral neck antetorsion is vital for orthopedic diagnosis and management.
