Abstract
Abstract An apparatus for use in retaining spinal elements in a desired spatial relationship includes a fastener for engaging a spinal element. A longitudinal member is positionable along the spinal column. A connector member interconnects the fastener and the longitudinal member. The connector member has a mounting section with surface means defining a first opening through which the fastener extends. The longitudinal member extends through a second opening in the connector member. The axis of the opening through which the longitudinal member extends is perpendicular to top and bottom surfaces of the connector member. The mounting section has a side surface extending at an acute angle to the top and bottom surfaces. The connector member includes a surface that is parallel to the longitudinal axis of the opening through which the longitudinal member extends. The side surface of the mounting section extends at an acute angle to the surface of the connector member which is parallel to the longitudinal axis of the opening through which the longitudinal member extends.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
An apparatus for use in retaining spinal elements in a desired spatial relationship, said apparatus comprising: a fastener for engaging a spinal element; a longitudinal member positionable along the spinal column; and a connector member for interconnecting said fastener and said longitudinal member, said connector member including surface means defining a first opening through which said longitudinal member extends, said connector member having a mounting section with surface means defining a second opening extending through a side surface of said mounting section and through which said fastener extends, the axis of the first opening through which said longitudinal member extends being perpendicular to top and bottom surfaces of said connector member, said side surface of said mounting section, through which said second opening extends, intersecting said top and bottom surfaces and extending at an acute angle to said top and bottom surfaces.
Claim 2
Independent Claim
142 words
An apparatus for use in retaining spinal elements in a desired spatial relationship, said apparatus comprising: a fastener for engaging a spinal element; a longitudinal member positionable along the spinal column; and a connector member for interconnecting said fastener and said longitudinal member, said connector member including surface means defining a first opening through which said longitudinal member extends, said connector member having a mounting section with surface means defining a second opening extending through a side surface of said mounting section and through which said fastener extends, the axis of the first opening through which said longitudinal member extends being perpendicular to top and bottom surfaces of said connector member, said side surface of said mounting section, through which said second opening extends, intersecting said top and bottom surfaces and extending at an acute angle to said top and bottom surfaces.
Claim 3
Dependent Claim
57 words
An apparatus as set forth in claim 1 wherein said side surface of said mounting section, through which said second opening extends, extends at an acute angle to a surface of said connector member perpendicular to said top and bottom surface and parallel to the longitudinal axis of the first opening through which said longitudinal member extends.
Claim 4
Independent Claim
155 words
An apparatus for use in retaining spinal elements in a desired spatial relationship, said apparatus comprising a one-piece connector member for interconnecting a fastener for attaching said connector member to a vertebra of the spinal column and a longitudinal member, means for clamping said connector member to the fastener, and means for clamping said connector member to the longitudinal member, said connector member having first surface means defining a first opening extending through a first surface of said connector member in a first direction and through which the longitudinal member is extendable, said connector member having second surface means defining a second opening extending through said connector member in a second direction through which the fastener is extendable, said first direction extending perpendicular to said first surface of said connector member, said first surface of said connector member lying in a first plane, said second direction extending at an acute angle to the first plane.
Claim 5
Independent Claim
155 words
An apparatus for use in retaining spinal elements in a desired spatial relationship, said apparatus comprising a one-piece connector member for interconnecting a fastener for attaching said connector member to a vertebra of the spinal column and a longitudinal member, means for clamping said connector member to the fastener, and means for clamping said connector member to the longitudinal member, said connector member having first surface means defining a first opening extending through a first surface of said connector member in a first direction and through which the longitudinal member is extendable, said connector member having second surface means defining a second opening extending through said connector member in a second direction through which the fastener is extendable, said first direction extending perpendicular to said first surface of said connector member, said first surface of said connector member lying in a first plane, said second direction extending at an acute angle to the first plane.
Claim 6
Dependent Claim
53 words
An apparatus as set forth in claim 3 wherein said first direction extends parallel to a second surface of said connector member, said second surface of said connector member extending perpendicular to said first surface and lying in a second plane, said second direction extending at an acute angle to the second plane.
Claim 7
Dependent Claim
48 words
An apparatus as set forth in claim 3 wherein said connector member has a mounting section through which the second opening extends, said mounting section having a side surface, through which the second opening extends, extending at an acute angle to said first surface of said connector member.
Claim 8
Dependent Claim
35 words
An apparatus as set forth in claim 5 wherein said side surface of said mounting section, through which the second opening extends, extends at an acute angle to said second surface of said connector member.
