Abstract

A subacromial spacer (10) is provided as a device for treating a shoulder with, a severe or irreparable lesion of the rotator cuff, by keeping a predetermined distance between an acromion and a corresponding humeral head. The subacromial spacer (10) has an articulating surface (11) whose radius of curvature (R) is longer than the radius of curvature of the humeral head of any possible patient, in particular radius (R) is longer than 60 mm, such that articulating surface (11) of subacromial spacer (10) and humeral head (52) reciprocally engage in a substantially punctiform contact, and humeral head (52) and articulating surface (11) roll without sliding with respect to each other. This way, a low friction arrangement is obtained, which drastically reduces articulation wear, i.e. the patient's healthy humeral head wear. The subacromial spacer according to the invention is therefore particularly suitable for treating those patients whose humeral head is not substantially compromised.
