Atlantoaxial instability in monozygotic twin sisters: degenerative or congenital disease?
The authors report on two 70-year-old monozygotic twin sisters who both suffered severe nontraumatic atlantoaxial instability. If either had been a solitary case, degenerative atlantoaxial instability would have been the most straightforward diagnosis. In this case report the authors attempt to answer the question of whether an underlying congenital predisposition might be involved.
