-12. (canceled)
A bone filling material comprising a bone-filling cement material and crimped fiber,
- wherein when the bone filling material is applied to an affected area of a patient, the crimped fiber is contained in a dispersed state within a cement matrix composed of the cement material, and
- wherein the crimped fiber contained in a dispersed state is obtained by cuffing, at intervals of from 0.5 mm to 10 mm, a loose web of short fibers composed of entangled crimped fibers, and comprises individual fibers having lengths of substantially not more than 10 mm.
A kit for preparing a bone filling material, comprising:
- a bone-filling cement material prepared in powder form, and
- a fibrous material which is used for mixture in the cement material, is obtained by cutting, at intervals of from 0.5 mm to 10 mm, a loose web of short fibers composed of entangled crimped fibers, and is composed of crimped fiber that comprises individual fibers having lengths of substantially not more than 10 mm.
