摘要： Systems are disclosed for hybrid knee arthroplasty including manual posterior femoral resection using a reusable cut guide and computer-assisted resection of other cuts. The cut guide includes a fixed component including an adjustment mechanism, an anterior portion, and a central portion between distal contact portions. Tracks are disposed between the central portion and each of the distal contact portions. The cut guide also includes an adjustable component that includes adjustable portions configured to be received by the tracks. An interior portion extends from the adjustable portions and is coupled to an exterior portion at a central divider. The interior portion is spaced from the exterior portion on the sides of the central divider to form cut slots. An actuator is coupled to the interior portion, in operable communication with the adjustment mechanism, and configured to move the adjustable component relative to the fixed component.

摘要： A bone alignment system (100) and method for aligning a fractured bone is disclosed. The system enables moving or pushing a bone fragment away from a bone alignment device (e.g., bone plate). Thus arranged, the system may be used to medialize a bone fragment to produce proper reduction and alignment prior to final fixation of the fractured bone. In addition, the system may enable fine adjustment of the bone fragment after provisional fixation without loss of reduction. The system includes a bone alignment device (e.g., bone plate 112), a guide (130), and a push rod (150). The guide being operative coupled to the bone alignment device. The push rod being threadably coupled to the guide. The push rod including a tip to contact, move, and maintain the bone fragment away from the bone alignment device.

摘要： A motorized strut for use in a motorized spatial frame in disclosed. The motorized strut including an adjustment mechanism arranged and configured to enable the motorized strut to be transitioned between first and second modes of operation. In the first mode of operation, the motorized strut is arranged and configured so that actuation of the motor is not required to translate an inner body of the motorized strut relative to an outer body of the motorized strut to adjust an overall length of the motorized strut. As such, in the first mode of operation, the overall length of the strut can be manually adjusted to facilitate more efficient (e.g., faster) length adjustment. In the second mode of operation, actuation of the motor is required to adjust the overall length of the motorized strut to facilitate slower, more precise adjustment of the motorized strut.

摘要： Described herein are systems and methods for the placement and design of the stability components of implant systems. Further, stability component assemblies, such as dual-mobility assemblies, for implant systems are also described herein. The systems and methods include using a standing sacral slope and a sitting sacral slope associated with a spine of a patient, determining a spine mobility based on the standing sacral slope and the sitting sacral slope, receiving poses of the implant system components, determining contact points between the components and locations of at least one of the components through a range of motion, receiving updated inclination and anteversion angles for the stability components of the implant system, and outputting an updated configuration for the stability component.

摘要： Methods and devices for bone adjustment, such as limb lengthening, are disclosed. For example, in one embodiment, a bone adjustment device may include a proximal portion configured to attach to a first bone portion, a distal portion configured to attach to a second bone portion, a motorized drive assembly, a control circuitry operably coupled to the motorized drive assembly, the motorized drive assembly and the control circuitry being hermetically sealed within a motor compartment, a driving element having a first end operatively coupled to the motorized drive assembly and a second end operatively coupled to the distal portion, the control circuitry is operative to receive wireless control signals from an external computing device, the motorized drive assembly is configured to be actuated based on the control signals to force rotation of the driving element to cause movement of the distal portion away from the proximal portion. Other embodiments are described.

摘要： The present disclosure provides a machine learning model to model a normal version of a bone from an abnormal version of the bone. The machine learning model can be trained with a training set including abnormal bone images and corresponding normalized, or post-operative, bone images. The abnormal bone image and the inferred normal bone image can be used to plan a surgery to correct the abnormal bone with a surgical navigation system.

摘要： An implant delivery system (40) is disclosed. The implant delivery system includes a delivery shaft (36) and a detachable frame (46) coupled to the distal portion of the delivery shaft and longitudinally advanceable relative to a delivery sheath (34). The detachable frame includes a body portion (56) and a plurality of attachment arms (64a-64c) extending away from the body portion; the body portion further includes a first support strut (65a) positioned adjacent to a second support strut (65b). The first support strut converges with the second support strut at a first convergence region, and a first attachment arm (64c) of the plurality of attachment arms extends away from the first convergence region. A tether (82) is secured to the detachable frame and extends through a lumen of the delivery shaft to a handle. The tether may be secured to a connection assembly (74), including a tack member (84), a tack disk (80) and a collar (76). The connection assembly may be attached to the detachable frame. The handle may include a tether clamp to secure the tether relative to the handle.

摘要： The present disclosure provides a surgical navigation system that utilizes multimodal tracking along with low profile/small diameter bone pins to fix FBG sensors to a patient. With some embodiments, a multi-core fiber optic cable having both an infrared (IR) tracking sensor disposed at a known location in the multi-core fiber optic cable and FBGs. The FBGs can be used to locate the tip of the cable relative to the IR marker, where the tip of the cable is embedded in a bone, the location of the done can be determined.
