La lamina elicoidale che forma le spire presenta alcune fissurazioni longitudinali a forma di scalpello che, incidendo chirurgicamente l’osso, ne asportano piccoli frammenti senza comprimere e in particolare permette di creare realmente una madrevite eliminando il maschiatore, previsto per ogni altro tipo di vite (fig.3).

The screws for the "tuber" area as an elongated tip which extends to a length of 35 mm. and has threads with a 5,5 mm. The helical blade which form the threads presents some scalpel fixtures which, when making a surgical bone incision, remove small fragments without compression and, in particular, permit the creation of a female screw eliminating a screw tap, necessary for every other type of screw (fig. 3).

spiral blade forming (or which forms) the thread...

Results: In nail SS, the proximally directed oblique locking screw came into contact with the ascending branch of the axillary nerve in 6 of 10 specimens. Mean distance from spiral blades in nails SS and SL were 26 mm to the axillary nerve and 16 mm to its ascending branch. Interlocking screws for nails SZ, SN, and SL did not violate the axillary nerve or its branches in any specimen.
