    Abstract: A method of pre-operatively developing a reverse shoulder arthroplasty plan can include receiving an image of a patient shoulder comprising a humerus and a glenoid. The image can be segmented to develop a 3D shoulder model. Virtual surgery can be performed on the 3D shoulder model to generate a modified shoulder model. The virtual surgery can include resecting and reaming a virtual humerus of the 3D shoulder model, and reaming a virtual glenoid of the 3D shoulder model. Selection of a humeral implant and selection of a glenoid implant can be received. A virtual representation of the humeral implant can be implanted on the virtual humerus and a virtual representation of the glenoid implant on the virtual glenoid to virtually update the modified shoulder model. A range of motion of the patient shoulder can be determined and a reverse shoulder arthroplasty can be finalized based on the range of motion.

  • Patent number: 10515324
    Abstract: A crew planning system includes a demand forecasting module and an optimization module. The system forecasts anticipated reserve demand levels, and determines suitable reserve staffing approaches to meet anticipated reserve demand. The forecasting is based upon probabilistic distribution models which take into account variability associated with reserve demand for a particular day. Via use of the crew planning system, reserve staffing expenses may be reduced and/or reserve demand may be met with a higher degree of probability.

  • Patent number: 10492916
    Abstract: A shoulder implant for reestablishing a coracoacromial arch in a subject, the shoulder implant comprising: a dorsal surface substantially shaped as a coracoacromial arch of a shoulder, the dorsal surface for engaging at least a posterior portion of the acromium of the subject when implanted in the subject; and an inferior surface substantially shaped as an acromiohumeral arch of a shoulder, the dorsal surface being opposite the inferior surface. The implant may have a spacer having a convex shape to simulate the anatomic contour of a acromiohumeral arch and the spacer coupled to a baseplate. In certain embodiments, the baseplate and the spacer have a convex surface that may extend the length of the inferior surface of the acromium and anteriorly to the coracoid process.

  • Patent number: 10478308
    Abstract: A humerus head implant includes a head cap, a fixing component, and a bone-screw component. The head cap has a shape of half-an-ellipsoid extending into a positive z-direction along the z-axis, in positive and negative x-directions, and in positive and negative y-directions. The extension along the x-direction is in a range of 0.8 to 0.95 of the extension in the y-direction. There is a conical recess having a center axis that is displaced in the negative y-direction with respect to the z-axis and configured to interface with a conical section of the fixing component. This allows for rotation of the head cap relative to the fixing component.

  • Patent number: 10342669
    Abstract: A glenoid system (100) includes a baseplate (102) configured to attach to a glenoid cavity of a patient. In a primary configuration, a biocompatible plastic liner (332) can snap into a circumferential groove (120) on the baseplate, to attach to a lateral facing surface (104) of the baseplate, at one or more locations around the groove. In a reverse configuration, a glenosphere (544, 644) can attach to an adapter (542, 642), which in turn can attach to the lateral-facing surface of the baseplate. The adapter can introduce lateral and/or angular offsets between the baseplate and the glenosphere, which can correct for unwanted offsets or inclinations. A middle peg extension (752) can screw onto a medial end of the middle peg (114), which can offer different combinations of peg length and peg material. The baseplates can be made available in various discrete sizes, each of which has the same distance between the middle peg and an inferior screw hole (112).

  • Patent number: 10251755
    Abstract: Method and set of surgical instruments for fitting a shoulder prosthesis, and the shoulder prosthesis. The proposed method seeks to interpose a bone graft between the previously prepared glenoid surface (G) of a scapula (S) of a patient's shoulder and the face of a glenoid prosthetic component opposite the articular surface. The set of instruments permit the bone graft to be taken from the upper epiphysis of the humerus (H), either in situ or ex vivo.

  • Patent number: 10245164
    Abstract: A glenoid trial and implant assembly for use in reverse total shoulder arthroplasty is provided along with a method for using the same. The glenoid trial and implant assembly includes a baseplate assembly, an adapter assembly, a glenoid trial, a glenoid implant, a humeral cup, and a positioning guide. The glenoid trial is coupled to the adapter assembly when the glenoid trial and implant assembly is assembled in a trialing configuration. The glenoid implant is coupled to the adapter assembly when the glenoid trial and implant assembly is assembled in an installed configuration. A temporary connection, which may be magnetic, releasably couples the glenoid trial to the adapter assembly and provides separation of the glenoid trial and the adapter assembly without requiring disassembly of the adapter assembly. A permanent connection fixes the glenoid implant to the adapter assembly.
