Pathogenesis of Volkmann's ischemic contracture of the first web space and treatment.

Reporting three cases of sequelae of Volkmann's ischemia of the first web space of the hand, following barbiturate overdose, the authors suggest several pathogenic hypothesis. The major factor is obviously an elective compression of the top of the first commissure on its dorsal aspect but it due to a compartmental syndrome or to a stoppage in the blood flow? The second explanation seems the best; the radial artery compressed at the top of the first commissure over the first dorsal intermetacarpal ligament is not able to vascularize the dorsal digital artery of the thumb and the first dorsal interosseous artery. These arteries being terminal in type, an elective muscle necrosis is takes place in the adductor pollicis and the first dorsal interosseous.

[Ureter opening into the seminal vesicle (author's transl)].

The authors present a case of ectopic opening of the left ureter into the seminal tract. This was a very young child (14 months). The diagnosis was made on intravenous pyelography on direct signs (opacification of the malformation).
