Abstract

A plurality of differently configured bone spinal implants for insertion in a spine have a cylindrical bore for receiving an insertion head stud. A plurality of instruments are disclosed each of which have a first connection element which is either a male or female member such as e.g., a ball and socket, a cylinder and socket and so on for forming either a stationary or articulating interchangeable joint for a plurality of disc processing heads or implant insertion heads. The plurality of disc space processing heads or implant insertion heads have a complementary second joint member for interchangeable attachment to the first connection element. The implant insertion heads or disc processing heads have different configurations for different shaped implants. Different instrument insertion or disc processing heads such as implant inserters, impactors, rasps, distractors, curettes, rongeur, and so on are disclosed as being interchangeable with a common instrument in which articulating or fixed joints are provided the interchangeable heads.
