摘要： An interbody implant is provided. The interbody implant includes a body having a cavity configured to retain material deposited in the cavity. The cavity has an opening defining a passageway in communication with the cavity. The implant further includes a membrane disposed about the opening of the cavity having a first configuration covering the opening and a second configuration such that the membrane exposes the passageway in communication with the cavity.

摘要： A dilator includes a first portion and a second portion movable between a first position and a second position. The first portion includes a first wall that defines a first cross section and a first cavity. The second portion includes a second wall that defines a second cross section, which is less than the first cross section, and a second cavity. The second portion dilates and/or dissects tissue adjacent a surgical site. In the first position, the second cavity provides direct visualization of the surgical site and the first cavity supports an instrument. In the second position, the second cavity is expandable such that the instrument is movable along the longitudinal axis in the second cavity. Methods of use are disclosed.

摘要： A retractor assembly for surgery in a patient includes at least one retractor member removably engageable to a support member. The retractor assembly includes a housing assembly engaged to the support member and to an arm that extends from a retraction portion of the retractor member. A drive mechanism in the housing assembly is coupled to the retractor member and is operable to rotate the retraction portion of the retractor member relative to the support member to a desired angular orientation.

摘要： Vertebral column manipulation systems include spinal derotation instrumentation to affect one or more derotation maneuvers on a scoliotic spine or on a spine having one or more displaced, misaligned or curved vertebral levels. Derotation instrumentation is attached to at least one vertebral body, with the instrumentation including at least two elongated extensions mounted to and extending proximally from the at least one vertebral body. A linking assembly extends between and links proximal ends of the extensions to one another. The linking assembly includes first and second mounting assemblies movably engaged to an elongate link member extending transversely to the extensions. Each of the mounting assemblies includes a movable joint for receiving the proximal end of a respective one of the extensions and a cam assembly for securing the mounting assembly in position relative to the link member and to fix the joint around the extension.
