## Abstract

An acetabular cup for a hip prosthesis, which includes a cotyle body provided with a number of holes for the passage of fixing screws. T holes are connected to each other by a number of ribs which define a grid.

## Claims

### Claim at position 1

1-13. (canceled)

### Claim 14

A cotyle for a hip prosthesis, which comprises a cotyle body provided with a plurality of holes for the passage of fixing screws, said holes being connected to each other by a plurality of ribs which define a grid.

### Claim 15 (depends on 14)

The cotyle according to claim 14, wherein said holes are surrounded by reinforcement rings.

### Claim 16 (depends on 14)

The cotyle according to claim 14, further comprising a base region which is provided solid and is frustum-shaped internally.

### Claim 17 (depends on 15)

The cotyle according to claim 15, wherein said ribs connect said reinforcement rings to each other.

### Claim 18 (depends on 14)

The cotyle according to claim 14, further comprising a polar central hole.

### Claim 19 (depends on 18)

The cotyle according to claim 18, further comprising a reinforcement ring arranged around said polar central hole.

### Claim 20 (depends on 19)

The cotyle according to claim 19, wherein said base region is covered externally by a porous mesh.

### Claim 21 (depends on 19)

The cotyle according to claim 19, further comprising a full-thickness porous mesh in areas of a surface of the body without ribs or reinforcement rings of the holes.

### Claim 22 (depends on 20)

The cotyle according to claim 20, wherein there are pointed regions on the surface of said porous mesh that covers said base region, of said mesh, of said ribs and reinforcement rings.

### Claim 23 (depends on 14)

The cotyle according to claim 14, wherein said base region has a height comprised between 12 and 14 mm.

### Claim 24 (depends on 14)

The cotyle according to claim 14, wherein said holes are arranged in a configuration according to a spiral.

### Claim 25 (depends on 21)

The cotyle according to claim 21, wherein said porous mesh that covers said base region is thinner than said full-thickness porous mesh that covers the areas of the surface of the body without ribs or reinforcement rings of the holes.

### Claim 26 (depends on 14)

The cotyle according to claim 14, provided with EBM or SLM techniques.
