A device for storing and mixing bone cement components. The device includes a housing, a safety device, and a vacuum indicator. The housing defines a mixing chamber configured to store a first bone cement component therein. In a first safety position, the safety device prevents contact between the first bone cement component and a second bone cement component in the mixing chamber. In a second safety position, the safety device permits contact between the first and second bone cement components in the mixing chamber. The vacuum indicator restricts movement of the safety device from the first safety position to the second safety position when in a first vacuum indicator position. The vacuum indicator permits movement of the safety device from the first safety position to the second safety position when in a second vacuum indicator position.

A robotic system for use in performing an arthroplasty procedure of a patient is provided. The robotic system includes a robotic mechanism, a cutting tool coupled to the robotic mechanism for resecting a portion of a bone of the patient through an incision in the skin of the patient, and a computer coupled to the robotic mechanism and configured to control the robotic mechanism. The robotic system also includes at least one navigation member positionable into engagement with tissue in the patient, an optical system coupled to the computer, a position sensor configured to provide movement information of the robotic mechanism relative to the bone, and an interface coupled to the computer, the interface configured to operate the computer.

A robotic surgical system is provided. The robotic surgical system includes a robotic mechanism having a force transmitting member and a computer connected with the robotic mechanism. The robotic surgical system also includes an optical sensing system connected with the computer, at least one navigation member configured to couple to one or more tissues of a patient, and a tool suitable for use in resecting at least a portion of a first bone of a joint in a patient and at least a portion of a second bone of the joint in the patient.

A method for stabilizing a leaking implanted device capable of being hydraulically adjusted by introducing or withdrawing hydraulic fluid to/from the device, the device having an inner space for enclosing the hydraulic fluid. The method comprises at least one of the steps of introducing at least one of: a solidifying fluid, an initiator adapted to exert influence on a solidifying fluid or the hydraulic fluid, and a mixture of a solidifying fluid and an initiator, into said leaking implanted hydraulically adjustable device for solidifying the solidifying fluid or the hydraulic fluid for permanently defining the volume and/or shape of the device, and repairing a leakage, puncture or rupture of the implanted hydraulically adjustable device by the introduction of a sealing component which forms a layer on the inside of the implanted hydraulically adjustable device preventing further leakage with retained function of the device, such that the repaired implanted hydraulically adjustable device can be hydraulically adjusted by introducing or withdrawing fluid to/from the device.

The embodiments provide provides devices, instruments, and associated methods for treating joint pain. A joint is evaluated using magnetic resonance imaging to detect any defects in the subchondral bone. For example, using T2-weighted MRI images, bone marrow lesions or edemas can be identified, and using T1-weighted MRI images, associated regions of sclerotic bone adjacent to the bone marrow lesion can be identified. The treatment method may involve introducing a bone void filler material at the site to address the bone marrow lesion or edema, and/or drilling and inserting an implant to address the sclerotic bone, bone marrow lesion or edema, and insufficiency or stress fractures. An access path is mapped to a location in the subchondral region where the insufficiency fracture resides. The access path attempts to preserve an articular surface of the joint. A reinforcing member that stabilizes the insufficiency fracture is then implanted via the access path.

Reduced bone fracture fixation devices and methods for using the same are provided. Aspects of the reduced bone fracture fixation devices include a body dimensioned to be positioned in a reduced bone fracture, wherein the body has a wedge shape configuration sufficient to exert a force on bone of the reduced bone fracture and maintain reduction of the reduced bone fracture. The devices, kits and methods of the invention find use in a variety of applications, such as in applications in which it is desired to repair a reduced bone fracture.
