Some measures are absolutely essential during primary care of injured hands in order to achieve primary healing (e. g., immediate closure of the wounds), whereas under certain circumstances other procedures may be endanger healing and should preferably be carried out secondarily (e. g., suturing of tendons and nerves). The author attempts to arrive at certain principles for the primary care of severely injured hands. On the basis of examples the author demonstrates in what manner the basis for sub- sequently necessary reconstructive procedures is created by planned primary care. Both procedures may be regarded as reconstruction in two steps and can be ca, rried out without unnecessary loss of time. The technique of dressing, type and duration of immobilization and follow-up treatment are also factors for the achievement of a good functional result. Dr. D. BUCK-GRAMCKO Handchirurg. Abteilung Berufsgenossenschaftliches Unfallkrankenhaus 205 Hamburg 80, Bergedorfer Strasse 10 N euere Operationstechniken in der Beugesehnenchirurgie Von W. PIEPER Der Erfolg einer Beugesehnennaht und Beugesehnenplastik im Verlaufe eines Fingers oder der Hand hangt, wie wir wissen, davon ab, dass die Naht- stelle und das Transplantat moeglichst narbenarm in das Sehnenlager ein- heilen. Die Gefahr der Vernarbung besteht wahrend der fur die Heilung der Sehnennahtstelle bzw. Einheilung des Sehnentransplantates notwendigen dreiwoechigen Ruhigstellung. Erst nach dieser Zeit sind die Sehne und das Tranplantat auf Zug und Dehnung fur die Bewegung belastungsfahig.
