Abstract
Official abstract text for this publication.
The invention discloses a support element for humeral implant comprising a central body extending along an axis and at least three arms extending outwardly from the central body, the arms being transversal to said axis and bearing a ring element at their ends opposite to said central body, wherein at least a first and a second pair of arms form different angles.
First claim
Opening claim text (preview).
The invention claimed is: 1. Support element for humeral implant comprising a central body extending along an axis and at least three arms extending outwardly from said central body, said arms being transversal to said axis and bearing a ring element at their ends opposite to said central body wherein an angle α formed between a first and a second adjacent arms being different from an angle β formed between a third arm that is adjacent to the first arm and the second arm, wherein there are no other arms between adjacent arms. 2. Support element according to claim 1 , wherein said angle α varies between 90° and 155°. 3. Support element according to claim 2 , wherein said angle α varies between 140° and 150°. 4. Support element according to claim 1 , wherein said angle β varies between 50° and 180°. 5. Support element according to claim 4 , wherein said angle β varies between 60° and 80°. 6. Support element according to claim 1 , wherein at least one of said arms has an outer rim on the side opposite to ring element—that is rectilinear. 7. Support element according to claim 1 , wherein at least two of said arms have an outer rim on the side opposite to ring element that is curvilinear. 8. Support element according to claim 1 , wherein said arms have a transversal section tapering from the central body towards the ring element. 9. Support element according to claim 8 , wherein the transversal section of said arms at the portion proximal to the ring element is 20-40% smaller than the transversal section at the portion distal from the ring element. 10. Support element according to claim 1 , wherein said central body is provided with an internal coaxial threaded blind hole. 11. Support element according to claim 1 wherein said ring element has a trabecular structure. 12. Support element according to claim 1 made of trabecular titanium. 13. Support element for humeral implant comprising a central body extending along an axis and at least three arms extending outwardly from said central body, said arms being transversal to said axis and bearing a ring element at their ends opposite to said central body wherein at least a first and a second pair of arms form different angles, wherein said ring element comprises a first cylindrical portion coaxial to said axis and a second integral cylindrical portion coaxial to a further axis forming an angle γ with said axis.
