Patent number: 7347873Abstract: An allogenic intervertebral implant for fusing vertebrae is disclosed. The implant is a piece of allogenic bone conforming in size and shape with a portion of an end plate of a vertebra. The implant has a wedge-shaped profile to restore disc height and the natural curvature of the spine. The top and bottom surfaces of the implant have a plurality of teeth to resist expulsion and provide initial stability. The implant according to the present invention provides initial stability need for fusion without stress shielding.Type: GrantFiled: June 9, 2005Date of Patent: March 25, 2008Assignee: Synthes (U.S.A.)Inventors: David C.

Publication number: 20060241763Abstract: An implant comprising two or more bone fragments that are combined to form a single unit. Cancellous bone or cortical bone is removed from a source and fashioned into bone components with desirable shapes and sizes. The bone components may be integrated to form implants for implantation in the body. Bone stock may be formed by combining sections of various bones of the body, and the bone stock may be further fashioned for use as implants with particular geometries.Type: ApplicationFiled: June 20, 2006Publication date: October 26, 2006Inventors: David Paul, Hansjuerg Emch, Beat Schenk, Michael Boyer, Thomas Higgins

Patent number: 6261296Abstract: A distractor for separating adjacent elements, such as vertebrae. The distractor preferably has a scissors-type distracting mechanism, either in a simple scissors or double-acting scissors configuration. Additionally, one or more of the blades, distracting mechanism, and handles are offset with respect to the other to facilitate visualization and to increase the space available for an implant holder. The blades are configured to enhance versatility of the distractor. In a first embodiment, the blades are removable from the jaws of the distractor such that different blades may be used depending on the patient and situation with which the distractor is to be used. In a second embodiment, curved portions are provided between the blades and jaws such that the blades are offset from the jaws in a smooth transition which does not expose sharp edges to internal organs or vasculature of the patient.Type: GrantFiled: October 1, 1999Date of Patent: July 17, 2001Assignee: Synthes U.S.A.Inventors: Max Aebi, Thomas Steffen, David C.

Patent number: 6143033Abstract: An allogenic intervertebral implant for fusing vertebrae is disclosed. The implant is an annular plug conforming in size and shape with end plates of vertebrae. The implant has either an exterior surface identical to that of the harvest bone or an exterior surface machined to have a uniform shape such as an oval or a rectangle. The top and bottom surfaces of the implant have a plurality of teeth to resist expulsion and provide initial stability. The top and bottom surfaces can be either flat planar surfaces or curved surfaces. Preferably, the anterior height of the implant is greater than the posterior height so that the implant is wedge-shaped profile to help restore disc height and the natural curvature of the spine. In one embodiment, the top and bottom surfaces each have a channel oriented in the anterior, lateral, or anterolateral direction for receiving a surgical instrument. The implant can also have a hole for attachment of an inserter.Type: GrantFiled: December 23, 1998Date of Patent: November 7, 2000Assignee: Synthes (USA)Inventors: David C. Paul, Hansjuerg W.
