Abstract
Knowledge of nail physiology is mandatory to understand nail pathologies, and to know what to repair and what to expect from your repair. Unfortunately, nail physiology in humans is not completely understood. However, there are some data that have been validated and must be known before treating patients. The nail plate is mostly made of keratins. It is produced solely by the nail matrix. The nail bed is mostly responsible for nail pate adhesion. At the hyponychium, the plate loses its adherence. The hyponychium is the first barrier of defense preventing bacteria and fungi from invading the subungual area. All these structures, along with the nail folds, are responsible for the orientation of nail-plate growth.
However, many questions, such as whether to replace the nail plate at end of procedure, remain open.
期刊介绍：
As the official publication of the French, Belgian and Swiss Societies for Surgery of the Hand, as well as of the French Society of Rehabilitation of the Hand & Upper Limb, ''Hand Surgery and Rehabilitation'' - formerly named "Chirurgie de la Main" - publishes original articles, literature reviews, technical notes, and clinical cases. It is indexed in the main international databases (including Medline). Initially a platform for French-speaking hand surgeons, the journal will now publish its articles in English to disseminate its author''s scientific findings more widely. The journal also includes a biannual supplement in French, the monograph of the French Society for Surgery of the Hand, where comprehensive reviews in the fields of hand, peripheral nerve and upper limb surgery are presented.
Organe officiel de la Société française de chirurgie de la main, de la Société française de Rééducation de la main (SFRM-GEMMSOR), de la Société suisse de chirurgie de la main et du Belgian Hand Group, indexée dans les grandes bases de données internationales (Medline, Embase, Pascal, Scopus), Hand Surgery and Rehabilitation - anciennement titrée Chirurgie de la main - publie des articles originaux, des revues de la littérature, des notes techniques, des cas clinique. Initialement plateforme d''expression francophone de la spécialité, la revue s''oriente désormais vers l''anglais pour devenir une référence scientifique et de formation de la spécialité en France et en Europe. Avec 6 publications en anglais par an, la revue comprend également un supplément biannuel, la monographie du GEM, où sont présentées en français, des mises au point complètes dans les domaines de la chirurgie de la main, des nerfs périphériques et du membre supérieur.
