  • Publication number: 20210322100
    Abstract: An apparatus includes a processor and a non-transitory memory. The processor is configured to receive pre-operative patient specific data. The pre-operative patient specific data is inputted to a first machine learning model to determine a first predicted post-operative joint performance data output including first predicted post-operative outcome metrics. A reconstruction plan of the joint of the patient is generated based on a medical image of the joint, and at least one arthroplasty surgical parameter obtained from the user. The at least one arthroplasty surgical parameter is inputted into a second machine learning model to determine a second predicted post-operative joint performance data output including second predicted post-operative outcome metrics.

  • Patent number: 9526627
    Abstract: Provided is an intervertebral implant to be implanted within an intervertebral space between endplates of adjacent vertebra during use. The implant includes an upper member having an inferior surface including an upper guide track and a superior surface to contact an endplate of an upper one of the adjacent vertebra during use, a lower member having a superior surface including a lower guide track and an inferior surface to contact an endplate of a lower one of the adjacent vertebra during use, and an insert having a superior surface including an upper guide rail to engage the upper guide track during use and an inferior surface including a lower guide rail to engage the lower guide track during use. Engagement of the upper and lower guide rails with the upper and lower guide tracks, respectively, guides insertion of the insert between the upper and lower members during use, and insertion of the insert between the upper and lower members facilitates expansion of the intervertebral implant.

  • Patent number: 9233003
    Abstract: Various embodiments of the present invention relate to an apparatus and method for reverse shoulder arthroplasty (e.g., reverse total shoulder arthroplasty). In one specific example, a glenoid component used to resurface the scapula may be provided. Of note, unlike traditional total shoulder arthroplasty the glenoid component in a reverse shoulder is convex rather than concave; it acts as a physical stop to prevent the superior migration of the humeral head—a typical occurrence in patients suffering from rotator cuff tear arthropathy (CTA).
