Systems and methods for ligament balancing during robotic surgery. One or more transducers are positioned within a knee joint to detect forces indicative of tension in ligaments and to provide output based on the detected forces. A distraction device is used to provide a distraction force to cause movement of a distal end portion of a femur relative to a proximal end portion of a tibia to increase tension in the ligaments. Information associated with output from the transducers is displayed for viewing.

Techniques and systems for distracting a spinal disc space and supporting adjacent vertebrae are provided. Trial instruments are insertable into the disc space to determine a desired disc space height and to select a corresponding implant. Implants can be also be self-distracting and the implant providing the desired disc space height can be implanted in the spinal disc space.

The present disclosure provides a system of gender specific pharmaceuticals. The system includes a first package of a pharmaceutical for use by a male and a second package of a pharmaceutical for use by a female. The first package includes a pharmaceutical for use by a male and a first label coupled to the first package, wherein at least one of the first package and first label includes a male specifier and a recommended male dosage. The second package includes a pharmaceutical for use by a female and a second label coupled to the second package, wherein at least one of the second package and second label includes a female specifier and a recommended female dosage.

Methods for treating an annulus fibrosis having a defect include inserting a flexible device into the defect. The flexible device is advanced distally beyond an outer layer of the annulus fibrosus. The flexible device is then expanded such that a width of the flexible device is larger than the defect, where the flexible device prevents escape of nucleus pulposus through the defect. The flexible device may have at least two appendages made from a shape-memory metal. Alternatively, the flexible device may have a U-shaped structure that includes a central portion and two legs. The flexible device may also be anchored to the annulus fibrosis and/or the vertebrae.

Methods for preparing a bone in surgery using an imaging system, a navigation system having a locating device, and a robotic system having a cutting tool. A cannula is guided into an incision to expand the incision and provide access to the bone so that the cutting tool is insertable through the cannula to remove material from the bone. An implant is insertable through the cannula to be placed in the bone.

Described herein is a method comprising molding a first component from a first feedstock comprising a first material powder and a first binder, molding a second component from a second feedstock comprising a second material powder and a second binder, placing the first component and the second component in physical communication with each other in order to form an assembled component, removing the first binder and the second binder from the assembled component and performing a sintering operation on the assembled component so as to bond the first component and the second component together.

A method and apparatus for replacing a selected portion of the anatomy is described. In particular, a prosthesis can be provided to replace a portion of an articulating joint, such as an elbow. The apparatus can be modular for various reasons and each of the modular portions can include a different dimension to achieve a selected result. For example, the prosthesis can achieve a different size condylar replacement, a selected offset, a selected articulation, or combinations thereof.

A medical device for treating hip joint osteoarthritis by providing a joint surface is provided. The medical device comprises at least two artificial hip joint surface parts, wherein said at least two artificial hip joint surface parts are adapted to be connected to each other to form an artificial hip joint surface during an operation. Furthermore a method of treating a hip joint of a human patient by providing said the medical device is provided. The hip joint comprising a caput femur and an acetabulum, the method comprises the steps of: cutting the skin of said human patient, dissecting an area of the pelvic bone on the opposite side from said acetabulum, creating a hole in said dissected area, said hole passing through said pelvic bone and into said hip joint of said human patient, and providing said medical device to said hip joint, through said hole in said pelvic bone of said human patient.

The invention relates to a femoral component (2) of a knee prosthesis. The component comprises a curved outer surface (4) for bearing against a tibial component. Said curved outer surface includes a posterior end and an anterior end. The curved outer surface includes an area (A) which extends from a first position closer to the posterior end to a second position closer to the anterior end, wherein said area (A) includes no parting line.

Mould and method for realizing a temporary prosthesis of hip or shoulder, which comprises a shaft and a head. The mould comprises: a first mould portion (1) comprising a first half-shell (2); a second mould portion (3) comprising a second half-shell (4); the first mould portion (1) and the second mould portion (3) being able to be coupled with respect to each other so that the first and second half-shell (2, 4) are counter-faced and define a chamber (5) which conforms a shaft portion (5a), a head portion (5b) and an opening (5c) for injection of a fluid (preferably viscous) material; fixing means (6) for fixing the first and the second portion (1, 3); a first insert (7) comprising a cap portion (8) which is realized as a unique body, is dimensioned to be inserted in the head portion (5b) and is conformed to give shape to the head of the prosthesis. The first mould portion (1), the second mould portion (3) and the first insert (7) are mutually conformed to obtain a temporary prosthesis, when the first mould portion (1) and the second mould portion (3) are coupled together, the first insert (7) is inserted in the head portion (5b) and the fluid (preferably viscous) material is injected in the opening (5c).
