ABSTRACT
A study to determine the degree of normal talar tilt in individuals with no history of ankle injuries was performed on 404 ankles of 202 midshipmen at the U.S. Naval Academy. Manual inversion stress roentgenograms were used to test this group of young healthy adults, most of whom were males. Of the 404 ankles tested, only 39 (9.7%) had any measurable talar tilt and only 7 ankles (1.7%) had a tilt over 5 degrees. Normal talar tilt does not range to 23 degrees. A normal ankle in a healthy young adult with no history of trauma has a small probability of having any talar tilt. When stress roentgenograms are used to evaluate a fresh lateral ankle ligament sprain in this type of individual, there is a very high probability that talar tilt over 5 degrees would represent significant injury to one or more of the lateral supporting structures.

Congenital idiopathic dilatation of the common bile duct, called commonly and incorrectly congenital cyst of the common bile duct, is sometimes diagnosed during pregnancy. The latter may be the source of severe complications. The disease should thus be treated rapidly, even if the pregnancy is at a late stage. In a case of this type we carried out surgical treatment in two stages: firstly simple external drainage of the common bile duct and of the gall bladder and only after labour has been brought to term by Caesarian section, for breech presentation, was a cystojejunostomy carried out on a Y shaped jejunal loop.
