| 摘要 |
A method of local treatment of specific bone defects such as osteoporosis or bone cysts comprises the step of local administration of a formulation comprising a fusion peptide containing a first domain comprising PTH or BMP 2 or BMP 7, and a second domain comprising a covalently crosslinkable substrate domain; and a material suitable of forming a biodegradable matrix suitable for cellular growth or in-growth, wherein the fusion peptide is covalently linked to the matrix. In one embodiment, the matrix contains one or more contrast agents, and is preferably formed in the absence of a growth factor. The matrix may be used in the treatment of fluid-filled cysts such as Tarlov cysts, ovarian cysts, arachnoid cysts, aneurysmal bone cysts or hepatic cysts.
