Two divots today.

Latha, today I scanned two patients, and each demonstrated the divot sign (indentation of the skin of the back of the neck by the cord). In each patient the spine was anterior. One patient was an insulin dependent diabetic with a BMI of 45.1, about 37 weeks. The cord could be traced on either side of the neck, but as usual I could not determine if the cord wrapped around the front of the neck, because this area was deeply shadowed by the neck itself.

The other patient was about 32 weeks (cannot remember for sure) and the cord clearly went down the left side of the neck and the right side of the skull. In other words, on the right the cord must have moved in the superior direction. Again, I could not tell if it went around the front of the neck.

I reported both of these.

Allen

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
