Spinal implant system and method
A spinal implant comprises a body including an inner surface that defines a cavity configured for disposal of a member. A locking element is engageable with the member within the cavity to fix the member with the body. The body further includes a wall that defines a bay configured for disposal of a longitudinal element being engageable with the wall to fix the longitudinal element with the body independent of the member. Systems and methods are disclosed.
1. A spinal implant comprising:
a body including an inner surface that defines a cavity configured for disposal of a member; and
a locking element engageable with the member within the cavity to fix the member with the body, the locking element comprising a screw and a fixation element that is connected with the screw by a pin to allow rotation of the screw relative to the fixation element,
the body further including a wall that defines a bay configured for disposal of a longitudinal element being engageable with the wall to fix the longitudinal element with the body independent of the member,
wherein the fixation element is engageable with the member within the cavity, the inner surface further defining a slot having a proximal end and a distal end, the fixation element being engageable with the inner surface adjacent to the ends to define a range of translation of the locking element within the cavity, the fixation element including an outer flange that is engageable with the inner surface adjacent to the ends.
2. A spinal implant as recited in claim 1 , wherein the cavity is separate from the bay.
3. A spinal implant as recited in claim 1 , wherein the cavity is separate and oriented transverse relative to the bay.
4. A spinal implant as recited in claim 1 , wherein the locking element is movable within the cavity between a non-locking orientation such that the member is movable relative to the body and a locked orientation such that the member is disposed between the locking element and the inner surface to fix the member with the body.
5. A spinal implant as recited in claim 1 , wherein the fixation element comprises teeth.
6. A spinal implant as recited in claim 1 , wherein the fixation element comprises a cleat.
7. A spinal implant as recited in claim 1 , wherein the screw translates relative to the body to engage and disengage the fixation element with the member.
8. A spinal implant as recited in claim 1 , wherein the locking element has a reduced diameter portion including a frangible torque limit.
9. A spinal implant as recited in claim 1 , further comprising a coupling member engageable with the longitudinal element to engage the longitudinal element with the wall.
10. A spinal implant as recited in claim 9 , wherein the coupling member comprises a screw that translates relative to the body.
11. A spinal implant comprising:
a body including an inner surface that defines a cavity configured for disposal of a member, the inner surface further defining a slot having a proximal end and a distal end; and
a cleat being translatable within the cavity and comprising a screw that is connected with the cleat by a pin to allow rotation of the screw relative to the cleat,
the body further including a wall that defines a bay configured for disposal of a longitudinal element being engageable with the wall to fix the longitudinal element with the body independent of the member,
wherein the cleat is engageable with the member within the cavity, the cleat being engageable with the inner surface adjacent to the ends of the slot to define a range of translation of the cleat within the cavity, the cleat including an outer flange that is engageable with the inner surface adjacent to the ends of the slot.
12. A spinal implant system comprising:
a connector including an inner surface that defines a cavity;
a tether configured for disposal within the cavity,
a locking element engageable with the tether within the cavity to fix the tether with the connector, the locking element comprising a screw and a fixation element that is connected with the screw by a pin to allow rotation of the screw relative to the fixation element to facilitate translation of the locking element into contact with the tether to engage and disengage the locking element with the tether,
the connector further including a wall that defines a bay configured for disposal of a spinal rod being engageable with the wall to fix the spinal rod with the connector independent of the tether,
wherein the fixation element is engageable with the tether within the cavity, the inner surface further defining a slot having a proximal end and a distal end, the fixation element being engageable with the inner surface adjacent to the ends to define a range of translation of the locking element within the cavity, the fixation element including an outer flange that is engageable with the inner surface adjacent to the ends.
13. A spinal implant system as recited in claim 12 , wherein the cavity is separate and oriented transverse relative to the bay.
14. A spinal implant system as recited in claim 12 , wherein the fixation element comprises a cleat.
15. A spinal implant system as recited in claim 12 , wherein the inner surface further defines a slot having a proximal end and a distal end, the fixation element being engageable with the inner surface adjacent to the ends to define a range of translation of the locking element within the cavity.
16. A spinal implant system as recited in claim 12 , wherein the locking element has a reduced diameter portion including a frangible torque limit.
