A kit comprising:

• an implant for maintaining a space between a humerus and a corresponding acromion, the implant comprising:
• a biocompatible member for maintaining a relative position between the humerus and the acromion, the biocompatible member comprising:
• a generally rounded second surface;
• and
• one or more attachment features disposed on the biocompatible member, wherein:
• the first surface configured to abut a humeral head of the humerus;
• the second surface configured to abut an inferior surface of the acromion;
• and
• at least one of the attachment features disposed on the second surface, configured to affix the biocompatible member to a proximal anatomical architecture;
• and
• a plurality of trial devices.

An apparatus for maintaining a space between a humerus and a corresponding acromion, comprising:

• an inflatable bladder for maintaining a relative position between the humerus and the acromion, the inflatable bladder comprising:
• a generally rounded second surface;
• and
• one or more attachment features disposed on the inflatable bladder, wherein:
• the first surface is configured to abut a humeral head of the humerus;
• the second surface is configured to abut an inferior surface of the acromion;
