An expansion member for distributing graft material through a cage and into an intervertebral space is provided. The expansion member has a central beam with an entry port in fluid communication with an exit port for distribution of the graft material. The central beam is inserted into a cage having a reversible collapse from an expanded state into a collapsed state, the expanded state forming a graft distribution window. The expanded state, for example, can be configured to open the graft distribution window which at least substantially closes upon the reversible collapse.

A method of treating a patient in need of an orthopedic implant is described. The method includes obtaining the T-score or bone density of the patient's native bone at a site of implantation, said T-score or bone density being determined by a DEXA scan or other means of determining a T-score or bone density. The method further includes selecting an orthopedic implant that has about the same density as the native bone at the site of implantation, and implanting the orthopedic implant at the site of implantation.

An expandable intervertebral implant (10) includes superior (20) and inferior (30) bone contacting members and at least one vertical wire netting (50) interconnecting the superior and inferior bone contacting members. The superior and inferior bone contacting members include at least two bone contacting components interconnected via one or more lateral wire nettings such that the implant is vertically and laterally expandable in situ from a first insertion configuration to a second expanded configuration. The vertical and lateral wire netting are preferably constructed of a plurality of individual link members. The present invention also preferably relates to an associated method of manufacturing the intervertebral implant such that the intervertebral implant can be manufactured as an integral component or part.

A surgical device is provided. The surgical device includes a tubular outer shaft having a longitudinal axis and an angled guide positioned on a first end of the surgical device. The angled guide may be angled relative to the longitudinal axis of the outer shaft. The surgical device includes an elongated inner shaft having a second end and a third end. The inner shaft is removably coupled to the outer shaft and configured to axially translate through the outer shaft. The surgical device includes pivotal device having at least one joint and an access tool. The at least one joint may be pivotally coupled to the third end of the inner shaft and to an end of the access tool. The pivotal device may be configured to axially translate through the angled guide into a deployed position.

Disclosed are devices for the fixation and support of vertebrae, particularly spinal implant devices formed from modular components of different materials.

An intervertebral fusion cage (1). The intervertebral fusion cage (1) is provided with a filler hole (11), which runs through both ends of the intervertebral fusion cage (1), and a plurality of pore areas (14) with spacings are provided on a side face of the intervertebral fusion cage (1). By means of a reasonable arrangement of the pore areas (14), a spacing is provided between the adjacent pore areas (14) so as to ensure that the intervertebral fusion cage (1) has a sufficient strength while having a predetermined elastic modulus, thereby preventing the intervertebral fusion cage (1) from being cracked or even broken when being subjected to an external force, which facilities solution of a technical problem of an insufficient strength of an intervertebral fusion cage (1) due to pore structures in the prior art.

Disclosed is an expandable interbody fusion implant that is configured to have an initial configuration having a first footprint width suitable for being inserted into an intervertebral space and an expanded configuration having a second footprint width that is greater than the first footprint width. The implant may include a first body member and a second body member that is pivotally coupled to the first body member. The implant may be expanded using an inflatable balloon. The implant may be expanded bilaterally such that both body members rotate relative to the other or the implant may be expanded unilaterally such that one of the body members rotates relative to the other.

The invention primarily relates to fastening and stabilizing tissues, implants, and/or bondable materials, such as the fastening of a tissue and/or implant to a bondable material, the fastening of an implant to tissue, and/or the fastening of an implant to another implant. This may involve using an energy source to bond and/or mechanically to stabilize a tissue, an implant, a bondable material, and/or other biocompatible material. The invention may also relate to the use of an energy source to remove and/or install an implant and/or bondable material or to facilitate solidification and/or polymerization of bondable material.

A bone graft delivery kit includes a hollow tube having a proximal end and a distal end, an implant and a plunger. The hollow tube is configured to be connected to the implant, and to convey bone graft material to a graft receiving area in a patient. The plunger is configured to facilitate moving the bone graft material through the hollow tube. The implant includes openings configured for passage of the bone graft material therethrough, and internal ramps configured to direct the bone graft material to the openings.

An intervertebral implant for implantation in an intervertebral space between vertebrae. The implant includes a body extending from an upper surface to a lower surface. The body has a front end, a rear end and a pair of spaced apart first and second side walls extending between the front and rear walls such that an internal chamber is defined within the front and rear ends and the first and second walls. The body defines an outer perimeter and an inner perimeter extending about the internal chamber. At least one of the side walls is defined by an integral porous structure.
