Spacer device for treating infections of the shoulder articulation

Spacer A spacer device for the two-stage treatment of infections of shoulder prostheses, comprising a humeral component equipped with a stem, wherein said humeral component comprises a proximal portion, wherein said stem is suitable for being inserted in use in the humerus of a patient and wherein said proximal portion is suitable for facing in use towards the glenoid cavity of the patient's shoulder, wherein said humeral component comprises a joining portion positioned between said stem and said proximal portion, wherein said spacer device comprises a head component and connection or articulation means of said humeral component with said head component, and said humeral component is obtained in a single piece with said stem, said proximal portion and said joining portion stably constrained to each other, and said proximal portion comprises a concave seat having a configuration substantially cup-shaped, or hemi-spherical or half-spherical regular, irregular or incomplete that makes said concave seat, wherein said proximal portion comprises a side or perimeter wall that makes said concave seat, defined by said wall, wherein said concave seat, during use, is suitable for at least partially containing or articulating with said head component, whereby said spacer device is capable of replacing in use various shoulder prosthesis types, in particular, both the prosthesis of “conventional” or “anatomic” type and that of “reverse” type and wherein said proximal portion also comprises a recess or notch which extends from said concave seat, within said joining portion towards the stem.
