Episode notes
Cause And Demographics Of Femoral Anteversion
- Femoral anteversion is a congenital packaging disorder from intrauterine positioning that increases femoral neck antiversion and causes compensatory internal rotation.
- Most cases are bilateral, seen in early childhood, and more common in girls with possible heredity.
Natural History And Age Changes
- Normal femoral anteversion at birth is 30–40° and decreases to about 15° by skeletal maturity.
- Minimal change occurs after age 8, which informs timing for intervention decisions.
Classic Presentation And Key Exam Findings
- Presentation includes intoeing, W-sitting, possible knee pain with tibial torsion, and awkward running; pain is usually absent.
- Examine hips prone for internal rotation >70° and external rotation <20° to identify femoral anteversion.
