Abstract: A gap balancing assembly includes an alignment plateau adapted to abut against an articular surface of a first bone, and at least one gap spacer portion adapted to space the articular surface from a second bone, the at least one gap spacer portion having a thickness profile. A spacer member has a first contact surface for being abutted against said tibial alignment plateau, and a second contact surface oriented and spaced relative to the first contact surface to correspond to the thickness profile of the at least one gap spacer portion, the second contact surface adapted to contact a cut guide to align same with the articular surface of the first bone.

Abstract: Disclosed herein are surgical guides, surgical supports, surgical systems, and methods of use thereof. The surgical guides, supports, and systems discloses herein can include an instrument and a patient-specific support. The instrument can be connectable to a surgical support arm and include a guide surface. The patient-specific support can comprise an instrument engagement portion and an anatomy contacting surface. The instrument engagement portion can be configured to receive a portion of the instrument and the anatomy contacting surface contoured to match a contour of an anatomical surface of a patient. When coupled to the patient-specific support, the surgical support arm and the patient-specific support can position the instrument and the guide surface in a predetermined location and orientation relative to the anatomical surface of the patient with increased stability.

Abstract: A device for registering a bone for a robotic shoulder arthroplasty with a surgical robot. The device can include a first portion engageable with a first portion of a bone and can include a second portion engageable with a second portion of the bone, the second portion connected to the first portion and rotatable with respect to the first portion. The device can include a registration device connectable to the first portion and configured to interface with the surgical robot for registration of the device and the bone. The device can include an actuator engageable with the first portion and the second portion to move the second portion toward a closed position away from an open position.

Abstract: An reaming system can be connectable to a robotic surgical system including an end effector of a robotic arm. The reaming system can include a reaming guide and a reamer. The reaming guide can include a body releasably couplable to the end effector at a proximal portion of the body and a housing located at a distal portion of the body. The reamer can be operable to ream bone. The reamer can include a support releasably couplable to the housing to secure the reamer to the reaming guide and the end effector. The reamer can include a cutting head connected to the support, the cutting head rotatable with respect to the housing when the support is coupled to the housing.

Abstract: Patient-specific instrumentation for reverse shoulder surgery includes a jig having a contact surface including a patient-specific surface portion negatively shaped as a function of a glenoid surface and configured to be applied against the glenoid surface in unique complementary engagement. A first throughbore opens into the contact surface, the first throughbore having an axis corresponding to a first altered bone plane in the glenoid surface. A second throughbore opens into the contact surface, the second throughbore having an axis corresponding to a second altered bone plane in the glenoid surface. The axes of the first throughbore and of the second throughbore are not parallel to one another.
