Devices to repair bone defects prevent the formation of depressions and palpable tissue at bone repair sites. The devices can be used to repair burr holes in the cranium, providing an improved cosmetic result that reduces or eliminates functional handicaps that can result from combing and hairdressing. The devices are secured in bone defects with filament elements, by expanding the device inside the bone defect, or by gluing. Tissue in-growth into the device regenerates bone at the defect site, and prevents the formation of depressions or palpable tissue. The devices preferably comprise a ceramic and poly-4-hydroxybutyrate or copolymer thereof, or a ceramic and poly(butylene succinate) or copolymer thereof. |
