Characteristics of the TWIN compression screw
TheTWIN compression screw has one thread at thescrew head and one thread at the screw tip.
The thread at the screw head has a larger diameterand a smaller pitch than on the screw tip. When thehead thread enters into the bone, this pulls the distantfragment in, that is, it produces compression.Theresult is therefore stable internal fixation of thefragment by means of compression
