Abstract
A prosthesis assembly for use with a scapula in one embodiment includes an acromion spacer unit, a first articulation surface on an inferior surface of the acromion spacer unit, a bone contacting surface on a superior surface of the acromion spacer unit, and a bone mounting member extending sideways from the acromion spacer unit and oriented such that when the acromion spacer unit is mounted on a scapula, the acromion spacer unit is positioned at a height above the height of a midpoint of a glenoid fossa of the scapula.
Claims10
A prosthesis assembly for use with a scapula, comprising:
- an acromion spacer unit configured such that when mounted on a scapula, the acromion spacer unit is separate from any component implanted at a midpoint of a glenoid fossa of the scapula such that a force against the mounted acromion spacer unit is not transferred to the component implanted at the midpoint;
- a first articulation surface on an inferior surface of the acromion spacer unit;
- a bone contacting surface on a superior surface of the acromion spacer unit;
- and
- a bone mounting member extending sideways from the acromion spacer unit and oriented such that when the acromion spacer unit is mounted on a scapula, the bone mounting member extends medially from the acromion spacer unit through an upper portion of the glenoid fossa and the acromion spacer unit is positioned at a height above a height of the midpoint of the glenoid fossa of the scapula.
A prosthesis kit for use with a scapula, comprising:
- a plurality of acromion spacer unit components, the plurality of acromion spacer unit components providing
- at least one first articulation surface of an acromion spacer unit configured to be movable with respect to any component located at a midpoint of a glenoid fossa of a scapula when the acromion spacer unit is mounted on the scapula such that a force against the mounted acromion spacer unit is not transferred to the component located at the midpoint,
- at least one bone contacting surface on a surface opposite the at least one first articulation surface of the acromion spacer unit, and
- at least one bone mounting member configured to extend sideways from the acromion spacer unit through an upper portion of the glenoid fossa when the acromion spacer unit is positioned above the midpoint of the glenoid fossa of the scapula.
