The tubular member comprises a proximal opening, a distal opening and a channel disposed therebetween. The proximal opening, the distal opening and the channel of the tubular member are configured to receive at least the portion of the plunger. The tubular member is movable in a first position to align the proximal opening of the tubular member with the second opening of the housing to allow the tubular member to receive at least the portion of the plunger to dispense the bone material. A method of implanting bone material with the bone material dispensing device is also provided.

A cement restrictor inserter instrument (130) comprises an inserter (131) having a handle (132) at a proximal end, a cement restrictor attachment formation (137) at a distal end for releasably attaching a cement restrictor (150), a shaft (136) extending from the proximal end to the distal end and a stop (138) on the shaft and between the proximal end and the distal end; and a body (140) having a shape corresponding to the shape of an orthopaedic prosthetic implant, a spacer (142), a visible depth guide feature (190) and a releasable attachment mechanism by which the body is releasably attachable to the shaft, and wherein the spacer is configured to position the visible depth guide feature at a fixed position relative to the inserter when the spacer abuts the stop corresponding to a target cement restrictor position when the visible depth guide feature is aligned with a feature of a bone of a patient in which the cement restrictor is to be inserted.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

A bone material dispensing device is provided. The bone material dispensing device comprises a housing having a proximal end, a distal end, and a longitudinal axis. The proximal end has a first opening and the distal end has a second opening. The first opening and the second opening are configured to slidably receive at least a portion of a plunger. A tubular member is provided that is pivotably connected to the housing and is configured for lateral movement relative to the longitudinal axis of the housing. The tubular member comprises a proximal opening, a distal opening and a channel disposed therebetween. The proximal opening, the distal opening and the channel of the tubular member are configured to receive at least the portion of the plunger. The tubular member is movable in a first position to align the proximal opening of the tubular member with the second opening of the housing to allow the tubular member to receive at least the portion of the plunger to dispense the bone material. A method of implanting bone material with the bone material dispensing device is also provided.

Methods and systems are provided for robotic assisted surgery. A robotic system includes a localizer, at least one controller, and a surgical robotic manipulator which separately and detachably receives an energy applicator and an implant insertion tool that detachably receives an implant specifically for knee, hip or shoulder replacement surgery. The at least one controller determines a location within a portion of a patient's anatomy in which to form a cavity for the implant. The surgical robotic manipulator is controlled to form the cavity with the energy applicator. The surgical robotic manipulator is then controlled to insert the implant into the cavity with the implant insertion tool.

A bone material dispensing device is provided. The bone material dispensing device comprises a housing having a proximal end, a distal end, and a longitudinal axis. The proximal end having a first opening and the distal end having a second opening. The first opening and the second opening configured to slidably receive at least a portion of a plunger. A locking member is provided that is pivotably connected to an upper surface of the housing and extends adjacent to the upper surface of the housing. The locking member comprises a locking surface extending adjacent to the distal end of the housing configured to engage a portion of a tubular member, a funnel, or a combination thereof. The locking member is movable in a locking position to lock the portion of the tubular member, the funnel, or the combination thereof with the housing. A bone material dispensing system and a method of implanting bone material with the bone material dispensing system are also provided.

Orthopaedic instruments for use in a direct anterior approach orthopaedic surgical hip replacement procedure on a patient's femur are disclosed. One such orthopaedic instrument may be embodied as a cement nozzle sized for insertion in a medullary canal of the patient's femur. The cement nozzle may include a first lumen for introducing a bone cement composition into the medullary canal. The cement nozzle may also include a second lumen for removing one or more bodily fluids from the medullary canal during introduction of the bone cement composition. The first and second lumens may each be curved along a distal portion of the cement nozzle.

A method for delivering a substance to bone includes placing a stabilizing wire in a bone, creating a hole in the bone around the stabilizing wire, and providing a multichannel cannula. The multichannel cannula includes a first channel having an open proximal end and distal end, the first channel being configured to receive the stabilizing wire, and a second channel having an inlet portal and an exit portal that are in fluid communication. The cannula further includes a cap having a delivery port in fluid communication with the inlet portal and a channel for receiving the cannula therein, and a distal tip. The method further includes inserting the multichannel cannula into the hole in the bone such that the first channel receives the stabilizing wire, and delivering the substance into the bone by introducing the substance into the second channel such that the substance exits through the exit portal.

A spinal implant comprises a body including an inner surface that defines a cavity. The inner surface includes a baffle. The body is disposable between a contracted configuration and an in vivo expandable configuration. Systems and methods are disclosed.

Apparatus is provided that includes a surgical tool for use with solid particles and a physiological liquid solution. The surgical tool includes (a) a shaft unit, which is shaped so as to define a delivery lumen, and a distal opening, which is disposed within 10 mm of a distal end of the shaft unit, in fluid communication with the delivery lumen; (b) a composition source, which is coupled in fluid communication with the delivery lumen, and which is configured to provide a solid-liquid composition of the solid particles and the physiological liquid solution; and (c) a pump, which is configured to pump the solid-liquid composition through the distal opening via the delivery lumen.
