A system for communicating fluid to or from a bone includes an insert. The insert includes a shaft extending between proximal and distal ends of the insert, a fenestration, and an expandable portion coupled to the shaft. The shaft is cannulated along at least a portion of the shaft between the proximal and distal ends. The fenestration is disposed along the cannulated portion of the shaft. Outer surfaces of the expandable portion are configured to expand laterally outward to increase the cross-sectional area of the expandable portion orthogonal to the shaft. |
