Abstract
Abstract An implant for correcting scoliotic, kyphotic and lordotic curves comprising a rigid member bearing at its ends on vertebrae adjacent but not included in the curve, and bridging the concave side of the curve. Threaded connecting members having hooks for engagement with vertebrae in the curve extend through apertures in the rigid bridge member and are connected to the rigid bridge member by nuts at the side of the rigid member remote from the vertebrae. Turning the nuts causes displaced vertebrae to be drawn towards the rigid member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
128 words
A surgical implant device for correcting a scoliotic curve and maintaining such correction, comprising: 1. a rigid bridge member of a material compatible with living animal tissue having a length dimension at least 10 times its width dimension to provide opposite ends to engage spaced vertebrae adjacent the curve with the intermediate portion of the bridge member spanning the curve; 2. tension means including at least two elongated members each configured to be hooked about a vertebra and extending from the same side of the bridge member to hook about a vertebra in the curve; 3. adjustable securing means on the tension means engaging the bridge member and serving to hold the tensiOn means which are hooked about the vertebrae in the curve drawn toward the bridge member.
Claim 2
Dependent Claim
128 words
A surgical implant device for correcting a scoliotic curve and maintaining such correction, comprising: 1. a rigid bridge member of a material compatible with living animal tissue having a length dimension at least 10 times its width dimension to provide opposite ends to engage spaced vertebrae adjacent the curve with the intermediate portion of the bridge member spanning the curve; 2. tension means including at least two elongated members each configured to be hooked about a vertebra and extending from the same side of the bridge member to hook about a vertebra in the curve; 3. adjustable securing means on the tension means engaging the bridge member and serving to hold the tensiOn means which are hooked about the vertebrae in the curve drawn toward the bridge member.
Claim 3
Dependent Claim
34 words
tension means including at least two elongated members each configured to be hooked about a vertebra and extending from the same side of the bridge member to hook about a vertebra in the curve;
Claim 4
Dependent Claim
34 words
tension means including at least two elongated members each configured to be hooked about a vertebra and extending from the same side of the bridge member to hook about a vertebra in the curve;
Claim 5
Dependent Claim
37 words
A surgical implant device according to claim 1 wherein the adjustable securing means on the tension means includes a threaded shank portion which extends through an aperture in the bridge member and is engaged by a nut.
Claim 6
Dependent Claim
19 words
A surgical implant device according to claim 2, wherein a plurality of said apertures are provided in said bridge.
Claim 7
Dependent Claim
32 words
adjustable securing means on the tension means engaging the bridge member and serving to hold the tensiOn means which are hooked about the vertebrae in the curve drawn toward the bridge member.
Claim 8
Dependent Claim
32 words
adjustable securing means on the tension means engaging the bridge member and serving to hold the tensiOn means which are hooked about the vertebrae in the curve drawn toward the bridge member.
Claim 9
Dependent Claim
56 words
A surgical implant device according to claim 3, wherein said apertures define a slot and discrete holes, the holes extending between the bottom of said slot and a surface of said bridge, each of said holes having a bounding surface conforming to a portion of a sphere for cooperation with a corresponding surface of a nut.
Claim 10
Dependent Claim
36 words
A surgical implant device according to claim 1 wherein each of said end portions of said bridge includes a lug for bearing against a portion of a vertebra adjacent to but not included in the curve.
Claim 11
Dependent Claim
118 words
A surgical implant device for correcting a scoliotic curve and maintaining such correction, comprising: a rigid elongate bridge member of a material compatible with living animal tissue for placement against the concave side of the curve so as to span the curve and have opposite ends thereof bear against spaced vertebrae; said bridge including a plurality of apertures; at least two tension members for extending independently from said apertures to vertebrae within the curve, each of said tension members having a screw-threaded portion and a hook portion for engagement with a vertebra, the hook members all extending in the same direction; and nuts for screw-threaded engagement with said screw-threaded portion of said tension members and with said bridge.
