Abstract: A synthetic bone substitute, includes a mixture of osteoconductive particles of first and second average particle sizes, suspended in a water-soluble reverse-phase hydrogel carrier in which the first average particle size is less than about 100 ?m, and the second average particle size is about 100-500 ?m. A method of producing the same is also described.

Abstract: A hip resurfacing femoral component is designed to be used with a prepared femur. The hip resurfacing femoral component comprises a head portion which has a substantially spherical outwardly facing bearing surface with an attachment surface opposing the bearing surface of the head portion. The femoral component further comprises a skirt portion with an outer skirt surface which depends from the substantially spherical bearing surface and an inner skirt surface. The inner skirt surface and the attachment surface are configured to fit over the prepared femur.
