[Intermaxillary immobilization using ring-screws in adults]. / Blocage intermaxillaire par pitons chez l'adulte.

We have been unsatisfied with the mandibular ligatures (binding) using Ivy type steel dental wire alone or with arch bars. The principal risks are: instability of ligature in patients with missing teeth AIDS, Hepatitis B and Hepatitis C infections periodental lesions We propose the use of anterior titanium implant screws or the monocortical "piton" which have been used up till now in maxillofacial bone reconstruction. Eight patients in one year have benefited from this procedure. This involved the implant of 32 "pitons" in fractured jaws and, for this study, in parasymphyseal areas

[Neurovascular sequelae related to the removal of forearm fasciocutaneous free flaps with radial pedicle. Preliminary study]. / Séquelles neuro-vasculaires liées au prélèvement des lambeaux libres fascio-cutanés anti-brachiaux à pédicule radial. Etude préliminaire.

The authors study the consequences of amputation of the radial artery in order to create a Chinese forearm graft on the blood supply and innervation of the upper limb. After a brief review of the anatomy, the haemodynamics of the upper limb are studied in detail. Preoperative assessment by Hallen's test is generally sufficient. Postoperatively, pulsed Doppler studies provide the most useful information. Compensatory development of the interosseous artery is always observed and, in seven out of nine cases, this is associated with a marked increase in the blood flow in all of the arteries of the upper limb, especially in the hand. Of all of the methods of investigation available, this examination is able to demonstrate the safety of forearm grafts in the very great majority of cases.
