Abstract: Navigated instrument guide systems and related methods can identify an absolute position of an instrument received within an instrument mount of a robotic arm. A navigation array unit of the guide system can include a main array and a mounted array. The main array can identify a position of the robotic arm and the instrument mount, while the mounted array can identify a depth position of a distal end of an instrument received within the instrument mount. The instrument can be passed through a lumen of the mounted array as the instrument is inserted into the instrument mount. The mounted array can be configured to translate relative to the instrument mount and the main array with distal translation of the instrument. In this manner, a position of the mounted array can identify a depth position of the instrument without a mechanical connection between the mounted array and the instrument.

Abstract: A control instrument 100 for a guidewire comprising a first component moveable from a first position, in which the guidewire can move axially relative to the first component, to a second position in which the guidewire is fixed relative to the first component and a second, rotatable, component, wherein rotation of the second component causes the first component to move axially, only when the first component is in its second position, thereby moving the guidewire move axially.

Abstract: Provided are methods and systems for enlarging a spinal canal of a vertebra. Using the methods and systems disclosed the spinal canal of the vertebra is enlarged by cutting the posterior arch portion of the vertebra to create one or two implant receiving spaces in the posterior arch portion. The cutting of the posterior arch portion is completed through a minimally invasive approach. Once cut, the detached portion of the posterior arch portion is repositioned and an implant is positioned in the implant receiving space of the posterior arch portion to thereby enlarge the spinal canal such that the spinal cord is no longer compressed. The insertion of the implant is also completed through a minimally invasive approach.

Abstract: A bone anchor coupler assembly is configured to couple a bone anchor to a spine stabilization member, and includes a coupler body and an angular adjustment member movably coupled to the coupler body.

Abstract: A mobile device includes a near field communications (NFC) radio and at least one sensor. A radio frequency (RF) signal emission status is modified in response to a change in state of the mobile device as determined by sensor data. Sensors may include motion sensors, light sensors, location sensors, time sensors, and others.

Abstract: An intervertebral implant comprising a lower implant part, having a central axis and an apposition section, designed to rest against the covering surface of the adjacent lower vertebra and an upper implant part comprising a bore with an internal thread, a central axis and an apposition section, designed to rest against the covering surface of the adjacent upper vertebra. Specifically, the lower and upper implant parts are secured in relation to each other against rotation about the central axis and a threaded screw with an external thread is guided in the upper implant part and connected to the lower implant part, the external thread cooperating with the internal thread. The lower and upper implant parts, and the threaded screw lie coaxially along their common central axis, the threaded screw being connected to the lower implant part so that it is axially fixed but able to rotate.

Abstract: An intervertebral implant having a lower implant part and an upper implant part. The lower implant part has an outer casing, a hollow cylindrical cavity, an axis of rotation, and an apposition part for contacting the lower vertebra. The upper implant part has an essentially circularly cylindrical shaft, which has an external thread, for extending into the cavity of the lower implant part, an axis of rotation, and an apposition part for contacting the upper vertebra. The two implant parts may be secured to prevent rotation about their axis of rotation. The implant also includes a ring with an internal thread, disposed between the two implant parts and interacts with the external thread of the upper implant part. Rotating the ring permits the distance between the two apposition parts to be adjusted. The ring may be axially fixed but rotatively movably with the lower implant part.
