Reduced-pressure, compression systems and apparatuses for use on a curved body part

A system for providing a force to a treatment area on a patient, comprising:

• a dressing assembly for placing on the treatment area, comprising:
• a longitudinal portion with a first end and a second end,
• a dressing bolster having a first surface and a second, inward-facing surface, and
• an envelope member surrounding the dressing bolster, wherein the envelope member comprises:
• an interior surface member having a first surface and a second, inward-facing surface, wherein the second, inward-facing surface of the dressing bolster is disposed proximate the first surface of the interior surface member, and
• an exterior surface member having a first surface and a second, inward-facing surface, wherein the second, inward-facing surface of the exterior surface member is disposed proximate the first surface of the dressing bolster;
• and
• a sealing subsystem for providing a fluid seal over the dressing assembly.

A dressing assembly adapted to provide a force to a treatment area on a patient, comprising:

• a longitudinal portion with a first end and a second end, the first end adapted to be coupled to the second end for releasably attaching the dressing assembly to the treatment area;
• a dressing bolster having a first surface and a second, inward-facing surface;
• and
• an envelope member surrounding the dressing bolster.
