Medial femoral torsion.

1. Medial femoral torsion is a common benign, spontaneously resolving deformity of childhood. 2. Nonoperative treatment is ineffective and therefore inappropriate. 3. It is fortunate that surgical correction is rarely necessary, for it carries significant risks of complications. 4. Severe medial femoral torsion is rare but carries the potential for disability. Surgery is the only method of correction, and should be undertaken only for serious persisting disability, not for prophylaxis.
