Abstract: A system for processing patient data associated with a joint of a patient. The system including a computing device executing instructions to provide a bone model of the joint that is representative of the joint of the patient in a first pose. The instructions further including rearranging the bone models relative to each other to mimic a second pose of the joint of the patient from at least one image or model representative of the joint of the patient in the second pose. The instructions further including planning a joint replacement procedure with the bone models after rearranging the plurality of bone models to mimic the second pose of the joint of the patient from the at least one image or model representative of the joint of the patient in the second pose.

Abstract: Methods of extracting bone and/or cellular material from a patient for possible use in a later surgical procedure, which involves that patient or even a different patient, are provided. An embodiment of the method generally comprises extracting bone and/or cellular material from a patient undergoing a routine surgical procedure, saving the material, and then sending it to a storage, separation, and processing facility (e.g., a “biobank”) for use in a later surgical procedure involving that patient, or a different patient. The material may be cancellous bone, cortical bone chips, or bone marrow. The extracted bone and/or cellular material can be processed at the biobank and used in a multitude of different medical procedures (e.g., as an allograft infused with stem cells for use in a fusion procedure).

Abstract: A powered surgical tool system. The system includes a handpiece having a motor and a front end attachment removably coupled to the handpiece. The attachment has a nose defining a bore for receiving a shaft of a cutting accessory connectable to a motor of the powered surgical tool for rotation. The nose also defines an enclosed channel separate from the bore. The channel extends longitudinally and helically along the nose such that the enclosed channel curves around the nose to curve around the bore. The channel has a variable pitch as the enclosed channel extends longitudinally. An irrigation fitting is in fluid communication with the enclosed channel in the nose and is adapted to receive an irrigating fluid and flow the fluid through the enclosed channel.

Abstract: In one embodiment, an expander set includes a first and second expander. The first expander includes an outer surface having a first engagement feature and a groove and the second expander includes an inside surface having a second engagement feature adapted to engage with the first engagement feature. The inside surface of the second expander is shaped to correspond to a portion of the outer surface of the first expander. Additionally, the groove on the outer surface of the first expander is sized and shaped to accommodate a rod of a retraction system such that when the first expander is advanced within the retraction system, the rod remains within the groove. When the first and second expanders are engaged with one another, they define an oblong cross-section.

Abstract: A front end attachment for a powered surgical tool. The front end attachment includes a nose. The nose defines a bore for receiving a shaft of a cutting accessory that is connectable to a motor of the powered surgical tool. The nose also defines a groove separate from the bore. The groove is formed in an outer surface of the nose and extends longitudinally along the nose. An irrigation fitting includes a tube that is seated in the groove of the nose. The irrigation fitting is adapted to receive an irrigating fluid. A heat shrink tubing is disposed over the outer surface of the nose to extend over and enclose the groove. The heat shrink tubing secures the irrigation fitting to the nose.

Abstract: A method of generating a correction plan for correcting a deformed bone includes inputting to a computer system a first image of the deformed bone in a first plane and inputting to the computer system a second image of the deformed bone in a second plane. Image processing techniques are employed to identify a plurality of anatomical landmarks of the deformed bone in the first image. The first image of the deformed bone is displayed on a display device. A graphical of the deformed bone is autonomously generated and graphically overlaid on the first image of the deformed bone on the display device, the graphical template including a plurality of lines, each line connected at each end to a landmark point corresponding to one of the anatomical landmarks. A model of the deformed bone may be autonomously generated based on the graphical template.
