Instruments, kits, and methods are disclosed for installing an implant spacer through an incision and down a surgical corridor. The instruments also serve to align a drill guide and align and insert a spacer stabilizer for stabilization of adjacent bone portions. An inserter instrument comprises an elongated guide bar body having a guide portion for aligning instruments with said spacer and for introducing a stabilizer to secure the spacer in a predetermined position between the bone portions. In preferred embodiments a stabilizer implant portion comprising a base wall separated by a retaining member by a web wall is introduced into a pre-bored hole in a bone and secured with a stabilizer anchor extending through a central bore. Included is a retractable graft block for securing graft material within an aperture of a spacer during insertion of the spacer.

An expandable spinal implant configured for positioning within a space between adjacent vertebral bodies includes an upper body, a lower body, a ratchet mechanism, and a plurality of bone screws. The upper body and lower body are pivotably affixed at a first end and are capable of movement relative to each other. The ratchet mechanism is slidably disposed on one of the upper and lower body and is capable of engaging the opposite one of the upper and lower body thereby permitting movement of the upper and lower body relative to each other in a first direction, but not in a second direction. An insertion instrument capable of being attached to the expandable spinal instrument and a method of performing spinal surgery is also disclosed.

A fibre-based surgical implant stabilized against fraying, includes a thermally crimped flat-knitted fabric of a biocompatible, optionally biodegradable, polymer material having a glass transition temperature or other thermally induced secondary conformational mobility threshold in the temperature range of from 20 C. to +170 C. Also disclosed is a corresponding fabric and methods of producing the implant and the fabric.

An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

A bone graft delivery system and method for using same to deliver graft material into a surgical site. The system includes an interbody implant having a securing site disposed on a surface of the implant and a holder having an elongated, hollow handle including a distal end. The distal end of the holder is configured to removably engage the securing site of the interbody implant to secure the interbody implant to the distal end of the holder until such time as a user desires to disengage the holder from the interbody implant. The interbody implant may be a cage implant having opposing anterior and posterior surfaces, opposing first and second lateral surfaces, and opposing top and bottom surfaces, wherein the top surface comprises a first aperture and the bottom surface comprises a second aperture, the posterior surface comprising a third aperture, the first, second, and third apertures all linking to a main cavity, the main cavity generally extending between the top surface and the bottom surface.

The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

A spinal implant is disclosed for engagement to portions of a spinal segment after a laminectomy procedure. The spinal implant includes a first member and a second member in orthogonal relation relative to the first member such that the spinal implant generally defines a t-shape configuration. The spinal implant is formed using biocompatible materials to safely adapt to the surgical area. The spinal implant may include hooks or apertures for engaging with portions of bodily tissue. The spinal implant may be engaged to other spinal implants along the spine using one or more arms of an interconnecting arrangement.

Expandable fusion devices, systems, and methods thereof. The expandable fusion implant may include upper and lower endplates configured to engage adjacent vertebrae and an actuator assembly for expanding the upper and lower endplates to independently control anterior and posterior heights of the implant. The actuator assembly may be operated in two modes: (1) to force the upper and lower endplates apart resulting in parallel expansion; and (2) to increase the anterior height of the implant resulting in an increase in lordotic angle.

Devices, systems and methods for surgical treatment of mid-foot disorders such as osteoarthritis, spacing disorders, or alignment disorders, including mid-foot arthroplasty devices and systems for the 2.sup.nd and 3.sup.rd tarsometatarsal (TMT) joint, implants for post-osteotomy spacing and realignment, arthroplasty articular implants, dowel grafts for TMT arthrodesis or fusion, dowel grafts for navicular cuneiform (NC) arthrodesis, dowel grafts for intercuneiform arthrodesis, and/or locking dowels for joint fusion.

Internal beam plates and associated instrumentation may be utilized for performing arthrodesis procedures, bone fracture procedures, osteotomy procedures, etc. Exemplary surgical methods that may be performed using the internal beam plates and associated instrumentation include, but are not limited to, lapidus bunionectomy procedures, metatarsophalangeal (MTP) procedures, chevron procedures, fracture repair procedures, etc. The exemplary internal beam plates incorporate an integral beam that is configured to increase strength and stiffness across a fusion site. The exemplary cutting/prep guides are configured to allow surgeons to reduce, prepare, and cut bones for receiving the beam of the internal beam plate using one or more guides.
