Zusammenfassung: | The modular complex for hip prosthesis comprises a femoral shank 1 which receives a set of collars 2 in a connected and interchangeable way which are able to act together with a spherical femoral head 3. Each collar 2 has a common frustoconical base 2a which is capable of being threaded into a recess of matching frustoconical shape formed angularly in the proximal part of shaft 1 and angularly with respect to its vertical axis, this base 2a being extended by a positioning member 2b which is intended to be engaged in different angular orientations with matching shapes 1b present in the base of the bore with the ability to lock angularly in the position in question.
Il complesso modulare per protesi di anca comprende un gambo femorale (1) che riceve in modo raccordato e intercambiabile una serie di colli (2) atti a cooperare con una testa sferica femorale (3). Ogni collo (2) presenta una base troncoconica comune (2a) atta ad essere infilata in un alesaggio di forma troncoconica complementare formato angolarmente nella parte prossimale dell'asta (1) e angolarmente rispetto al suo asse verticale, tale base (2a) essendo prolungata da un elemento di posizionamento (2b) destinato ad essere impegnato secondo differenti orientamenti angolari in forme complementari (1b) presenti nel fondo dell'alesaggio con capacità di bloccaggio angolare nella posizione considerata. |
