| 发明名称 | Ball joint prosthesis and method | ||
| 摘要 | A ball joint prosthesis can include a shell, having an outer articular surface of a first material and an open distal end, configured to receive a sealing receptacle. A volume of a second material, within the shell, can be more compressible than the first material. The ball joint prosthesis can have an effective compressibility that is intermediate between a compressibility of the first material and a compressibility of the second material. | ||

| 主权项 | 1. A ball joint prosthesis, comprising: a shell, comprising: an outer articular surface of a first material having a first compressibility; andan open distal end, configured to receive a portion of a sealing receptacle; and a volume of a second material, within the shell, the second material having a second compressibility that is greater than the first compressibility of the first material, wherein the sealing receptacle is coupled to the first material or formed of the first material, and is configured to accept a portion of a prosthetic orthopedic stem to the ball joint prosthesis, wherein the ball joint prosthesis has an effective compressibility that is intermediate between the first compressibility of the first material and the second compressibility of the second material. | ||
