An instrument and inserter kit for providing a load to insert or retract an implant 2000 is provided. The instrument includes a cover having an engagement end opposite a distal end. The engagement end is configured to mount to an engagement feature of a handle of an inserter. The cover is an elongated member having a C-shaped profile having a dimension configured to receive a sliding member. The sliding member is seated over the cover and is weighted. The sliding member is configured to slide between a first radial lip and a second radial lip so as to provide an impacting force or retracting force on the instrument.

Methods and apparatus are disclosed for distracting tissue. The devices and methods may include insertion of first and second elongated members into the space between two tissue layers, with an augmenting elongated member at least partially inserted therebetween to form a distraction device between the tissues to be distracted. At least one of the first and second elongated members may be formed of a flexible core member with a plurality of rigid veneer members spaced along the length of the core member. At least one of the elongated members may include a shaping member that automatically moves from a generally linear configuration to a generally less linear configuration. A deployment catheter may include a deformable distal end to allow augmentation of the tissue distraction device during implantation. An injection aid may be provided for introducing a filler material into an interior defined by a deployed tissue distraction device.

A spinal implant configured for positioning within a space between adjacent vertebral bodies includes an upper end plate including an outer surface extending between first and second end surfaces and opposed side surfaces. The outer surface includes a first convex profile extending between the first and second end surfaces and a second convex profile extending between the opposed side surfaces. The first convex profile and the second convex profile have different curvatures. The spinal implant further includes a lower end plate and a core disposed between the upper and lower end plates and coupled thereto. A method of assembling a spinal implant and a method of performing spinal surgery are also disclosed.

The present invention relates generally to medical devices, systems, and methods for use in surgery. In particular, the disclosed system and methods relate to an intervertebral spinal implant sized and dimensioned for the lumbar spine implantable via a posterior approach. The system includes an implant, instruments for delivering the implant.

A bone fusion method, system and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable tabs having a central rib. The bone fusion device includes one or more support channels configured to receive an insertion instrument that is then secured to the bone fusion device via a coupling mechanism. As a result, the coupled device is able to be securely positioned between vertebrae using the insertion instrument with minimal risk of slippage.

An implant insertion tool for use during a surgical procedure to implant an acetabular cup component into a surgically-prepared acetabulum of a patient's hip includes a metallic elongated shaft, a removable polymeric grip, and a locking nut to secure the grip to the elongated shaft. Such a modular design allows the implant insertion tool to be dissembled prior to sterilization.

Disclosed herein are systems and methods for intervertebral body fusion that provide more robust support within the disc space. Intervertebral body fusion devices can have a unitary monolithic body including a plurality of body segments interconnected with each other by flexure members. Devices can be configured to be inserted through an opening in a compressed configuration and then expanded within the disc space to an expanded configuration. In the expanded configuration, devices can have a greater mediolateral or transverse to the disc space footprint. This wider footprint provides greater support for the vertebrae relative to the size of the opening through which the device is inserted. Insertion devices for inserting, expanding and extracting such implants are also disclosed.

Systems are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The systems include a drill guide having a bone dislodging member adapted to create a pilot SI joint opening in the dysfunctional SI joint through an incision comprising a length no greater than 3.0 cm; portions of the pilot SI joint opening being disposed in the sacrum and ilium bone structures. The drill guide includes a tri-mode fixation system adapted to position and stabilize the drill guide during creation of the pilot SI joint opening in the dysfunctional SI joint and delivery of the SI joint prosthesis therein. The systems also include a SI joint prosthesis configured to be inserted into the pilot SI joint opening of the dysfunctional SI joint, a prosthesis deployment assembly configured to engage the SI joint prosthesis and advance the SI joint prosthesis into the dysfunctional SI joint, and a bone harvesting assembly adapted to extract and collect dislodge bone material from the bone dislodging member after creation of the pilot SI joint opening.

An orthopaedic surgical instrument may include an elongated body with an implant end and an impactor end. A latch lever may be pivotally coupled to the elongated body. The latch lever may be moveable between an open position and a latched position in which the latch lever is retained within the body. An acetabular shell component may be rigidly attached to the implant end of the elongated body. An automated surgical impactor may be attached to the impactor end.

Implants and instruments for providing an ideal trajectory for the insertion of instruments and screws during implantation of an interbody implant in a spinal surgery are disclosed.
