Abstract
Interspinous process implants are disclosed. Also disclosed are systems and kits including such implants, methods of inserting such implants, and methods of alleviating pain or discomfort associated with the spinal column.
Claims13
A method of installing an implant between adjacent spinous processes comprising:
- inserting an implant between adjacent spinous processes, the implant having an elongate body having a longitudinal axis, the elongate body including a leading end portion, a trailing end portion, and a central support portion disposed between the leading and trailing end portions, wherein the trailing end portion includes a flange defining a sidewall configured and dimensioned to contact at least one of the adjacent spinous processes;
- a pair of tabs independently attached to the leading end portion, each tab having a first end and second end, wherein each tab has teeth radially disposed around the first end;
- and a gear barrel insert extending through the trailing end portion and the central support portion;
- and
- extending the pair of tabs by rotating the gear barrel insert such that the second end of each of the pair of tabs extends outwardly from the leading end portion, and wherein the leading end portion extends from a proximal portion to a distal portion, and the pair of tabs are rotatably attached to the proximal portion of the leading end portion,
- wherein the gear barrel insert has a worm gear configured and dimensioned to engage the teeth on the first end of each of the pair of tabs.

- and a gear barrel insert extending through the trailing end portion;
- and
- moving the one or more tabs by rotating the gear barrel insert such that the one or more tabs extend outwardly from the leading end portion, and wherein the leading end portion extends from a proximal portion to a distal portion, and the one or more tabs are rotatably attached to the proximal portion of the leading end portion,
- wherein the gear barrel insert has a worm gear configured and dimensioned to engage the teeth on the first end of each of the pair of tabs.

A method of installing an implant between adjacent spinous processes comprising:
- inserting an implant between adjacent spinous processes, the implant having an elongate body having a longitudinal axis, the elongate body including a leading end portion, a trailing end portion, and a central support portion disposed between the leading and trailing end portions, wherein the trailing end portion extends from a proximal end to a distal end, and the trailing end portion includes a flange proximate to the distal end;
- a pair of tabs independently attached to the leading end portion, each tab having a first end and second end, wherein each tab has teeth radially disposed around the first end;
- and a gear barrel insert extending through the trailing end portion, wherein the pair of tabs are generally recessed within the leading end portion to facilitate lateral insertion between the adjacent spinous processes;
- and
- maintaining the adjacent spinous processes between the pair of tabs by rotating the gear barrel insert such that the second end of each of the pair of tabs extend outwardly from the leading end portion, and wherein the leading end portion extends from a proximal portion to a distal portion, and the pair of tabs are rotatably attached to the proximal portion of the leading end portion,
- wherein the gear barrel insert has a worm gear configured and dimensioned to engage the teeth on the first end of each of the pair of tabs.
