Filed:

Apr 13, 2012

Appl. No.:

13/506365

Inventors:

Roger P. Jackson - Prairie Village KS, US
James L. Surber - Kansas City MO, US

International Classification:

A61B 17/04
A61B 17/84
A61F 2/08

US Classification:

606300, 606305

Abstract:

A polyaxial bone screw assembly includes a threaded shank body having an integral upper portion receivable in an integral receiver, the receiver having an upper channel for receiving a longitudinal connecting member and a lower cavity cooperating with a lower opening. A down-loadable compression insert with tool receiving arm extensions, a down-loadable friction fit split retaining ring and an up-loadable shank upper portion cooperate to provide for pop- or snap-on assembly of the shank with the receiver either prior to or after implantation of the shank into a vertebra. The shank and receiver once assembled cannot be disassembled.

International Classification:

A61B 17/70

US Classification:

606269, 606264, 606266, 606305, 606306

Abstract:

A polyaxial bone screw assembly includes a threaded shank body having an integral upper portion receivable in a receiver, the receiver having an upper channel for receiving a longitudinal connecting member and a lower cavity cooperating with a lower opening. The upper portion expands a retaining member in the receiver cavity to capture the shank upper portion in the receiver. In some embodiment either the retaining member or an insert provide for a friction fit of the shank upper portion in the receiver resulting in non-floppy placement of the shank with respect to the receiver. Some retainers and inserts have a lock-and-release feature. Final locking of the polyaxial mechanism is provided by frictional engagement between the shank upper portion and the retaining member. A pre-assembled receiver, retaining member and optional insert may be popped-on or snapped-on to the shank upper portion prior to or after implantation of the shank into a vertebra.

International Classification:

A61B 17/70
A61B 17/88

US Classification:

606264, 606279

Abstract:

A dynamic fixation medical implant having at least two bone anchors includes a longitudinal connecting member assembly having rigid sleeves for attachment to the bone anchors, at least one spacer engaging the bone anchors and the sleeves, and in some embodiments, an end elastic bumper. A flexible cord is initially slidingly received within the rigid sleeves, the spacer and the bumper. The spacer may include an optional inelastic inner liner, with at least one of the sleeves having an extension slidingly receivable within the liner. Some sleeves include apertures for receiving a closure top portion for locking the cord against the sleeve, or alternatively receiving a closure top that does not extend into the aperture, the slip or grip option provided by the aperture in each sleeve resulting in an overall connector with variable segmental stiffness.

International Classification:

A61B 17/70

US Classification:

606264

Abstract:

A spinal implant having at least two bone anchors includes a longitudinal connecting member assembly having hard, non-elastic sleeves for attachment to the bone anchors, at least one spacer engaging the bone anchors and the sleeves, and in some embodiments, an end elastic bumper. A cord is initially slidingly received within the rigid sleeves, the spacer and the bumper. The sleeves include a lower radiused surface for direct engagement with a radiused surface of a shank of the cooperating bone anchor. The sleeves include an aperture for receiving a closure top portion for locking the cord against the sleeve, or alternatively receiving a closure top that does not extend into the aperture, the slip or grip option provided by the aperture in each sleeve resulting in an overall connector with variable segmental stiffness.

Inventors:

Roger P. Jackson - Prairie Village KS, US
James L. Surber - Kansas City KS, US

International Classification:

A61B 17/86

US Classification:

606305

Abstract:

A polyaxial bone screw assembly includes a threaded shank body having an integral upper portion receivable in an integral receiver, the receiver having an upper channel for receiving a longitudinal connecting member and a lower cavity cooperating with a lower opening. The receiver can have crimp tabs, but is devoid of spring tabs and collet-like flexible structures. A down-loadable compression insert (some with lock and release feature), a down-loadable friction fit split retaining ring having super structure for temporary friction fit with an up-loadable shank upper portion cooperate to provide for pop- or snap-on assembly of the shank with the receiver either prior to or after implantation of the shank into a vertebra. The shank and receiver once assembled cannot be disassembled.

Abstract:

A polyaxial bone screw assembly includes a threaded shank body having an integral upper portion receivable in a receiver, the receiver having an upper channel for receiving a longitudinal connecting member and a lower cavity cooperating with a lower opening. The shank upper portion expands a retaining member in the receiver cavity to capture the shank upper portion in the receiver. The retaining member and attached shank are pivotable with respect to the receiver until locked in place with respect to the receiver. A pre-assembled receiver, retaining member and compression insert may be popped-on or snapped-on to the shank upper portion prior to or after implantation of the shank into a vertebra.

International Classification:

A61B 17/70

US Classification:

606259, 606264

Abstract:

A spinal implant having at least two bone anchors includes a longitudinal connecting member assembly having hard, non-elastic sleeves for attachment to the bone anchors, at least one spacer located between the bone anchors, and in some embodiments, an end elastic bumper and cord blocker. A cord is received within the rigid sleeves, the spacer and the bumper, the cord being in fixed or sliding relationship with cooperating sleeves. The sleeves include portions for direct engagement with bone screw inserts and closure tops and may include a channel for receiving a projected portion of a spacer.
