Abstract
Selectively demineralized bone-derived implants are provided. In one embodiment, a bone sheet for implantation includes a demineralized field surrounding mineralized regions. In another embodiment, a bone defect filler includes a demineralized cancellous bone section in a first geometry. The first geometry is compressible and dryable to a second geometry smaller than the first geometry, and the second geometry is expandable and rehydratable to a third geometry larger than the second geometry.
Claims20
A method of providing a bone implant comprising:
- demineralizing a block of cancellous bone having a first geometry;
- wetting the block;
- compressing the block from the first geometry to a second geometry smaller than the first geometry;
- permitting the block to harden after the block has been compressed to the second geometry.
A method of providing a bone implant comprising:
- demineralizing a block of cancellous bone having a first configuration;
- softening the block;
- compressing the block from the first configuration to a second configuration smaller than the first configuration;
- permitting the block to harden after the block has been compressed to the second configuration.
A method of providing a bone implant comprising:
- softening a block of demineralized, cancellous bone having a first volume;
- compressing the block to a second volume smaller than the first volume;
- permitting the block to harden after the block has been compressed to the second volume.
