Its hemostatic effect is physical rather than biochemical. Pressure from the plug, together with adherence to the bone surface, occludes vascular channels in cancellous bone and limits blood flow. Because this action does not depend on the coagulation cascade, the plug can provide local control where mechanical blockage of the bleeding bone surface is the intended outcome.
Cancellous bone contains vascular channels that can contribute to bleeding when a bone surface is exposed during a procedure. A moldable plug can conform to that surface and obstruct these channels through pressure and adherence. This relationship explains why placement at the bleeding bone surface is central to achieving local hemostasis and maintaining a workable operative field.
Persistence is an important consideration because the material may remain at the treated site rather than quickly disappearing. Its continued presence can interfere with bone healing or tissue integration, so the local biological response matters alongside immediate bleeding control. This creates a balance between effective hemostasis and the potential effects of retained material on surrounding skeletal tissues.
Placement should focus on the bleeding bone surface, where pressure and adherence can occlude vascular channels. The material is moldable, allowing it to be positioned to achieve local mechanical tamponade while preserving visibility of the operative field. Careful placement is important because the same material may persist and affect healing or integration in nearby tissue.
They are useful during procedures involving bone when local hemorrhage must be controlled and a clear operative field is needed. In experimental tissue preparation, they can also support handling of skeletal specimens. Their value therefore extends beyond immediate surgical hemostasis, although investigators must consider how retained material could influence the surrounding biological preparation.
The decision should weigh the need for mechanical bleeding control against the possibility that persistent material may interfere with bone healing or tissue integration. Site-specific biological effects are therefore relevant, particularly when the surrounding tissue must recover or incorporate with adjacent structures. This consideration helps determine whether the benefits of local hemostasis justify use at that location.
