1 TWIN TWIN Screw Ø 3.0 / 3.9mm Thread Diameter: 3.00mm Core Diameter: 2.05mm Head diameter: 3.90mm Thread pitch: 1.25mm Cannulation: 1.15mm 8 30mm Hexagon socket: 2.4 mm I (gold) General description: Reconstruction plates have lateral notches between the holes, whereby they can be bent and folded in two levels. The bending angle should amount to at no point more than 15. It should be noted that the strength of the board is reduced by the bending. The lockig plates can with fixed with locking and non-locking screws.

2 WINSTA-R WINSTA-R distal radius system General description: The problem posed by metaphyseal and intra-articular fractures lies in the fact that even though implants can be wellanchored in the distal section of the shaft, fixation stability is however limited in the spongiose bones of the fragment close to the joint. Multifragmentary, intra-articular fractures as well as senile osteoporosis exacerbate this problem. In relation to the long proximal shaft section, the lever arm of the short distal joint fragment mechanically unfavourable during functional treatment places high demands on the stability of the implant itself as well as on its fixation in the distal fragment. In contrast to conventional implants, angle stable ones enable early functional treatment (especially desirable in the case of fractures close to joints), which is of great importance for the rapid restoration of a joint s functional integrity. Adaptation of the plate form and of the direction of the distal angle stable plate screws or pins to the physiological articular surface axes and curvatures facilitates correct reposition as well as the ideal repositioning of the implant components, thus increasing postoperative fracture stability. System characteristics High stability in the case of small implant dimensions. Anatomically correct form with volar bending to reconstruct the palmar tilt, and secure support of the volar contour of the distal radius. The four distal plate holes are adjusted to the radioulnar curvature of the articular surface, and enable secure fixation of the distal radius even in the case of intra-articular fractures via subchondral positioning of the stabilization screws and pins. The given direction of the locking screws or pins at the distal plate end corresponds to the physiological dorsovolar inclination of the articular surface, and enables the screws or pins to be placed in the ulnar fragment as well as in the styloid process of the radius. For fixation in the distal fragment, either self-tapping locking cortical screws Ø 3.0 mm or locking buttress pins Ø 2.0 mm are available. For fixation of the plate, self-tapping cortical screws Ø 2.7 mm are available. In the case of osteoporotic bones, selftapping locking cortical screws Ø 3.0 mm can be used as an alternative. Precision drilling and length measurement for angle stable screws / pins via screw-in drill sleeve. For all screws and pins, only a Ø 2.0 mm drill bit is required. A cross-oval plate-hole enables reposition of intra-articular fragments as well as possible defect filling with spongiosa or bone substitute after plate fixation. The clearly laid-out instrumentarium facilitates handling. Various different plate lengths also suit the requirements of multiple metaphyseal fractures. Special surface treatment of plates and angle stable screws and pins by anodization type II Properties of processed products: - reduced tendency of cold welding of Titanium implants by screw in the locking pins and screws - hardened Titanium surface - increased fatigue resistance of implants - significant reduction of AL and V release Pfad: H:\QM_RA\Product data sheet\noch nicht geprüft\10 - Hand System.docx Page 2 of 8
