Abstract: A surgical assistance system may obtain a pre-revision model of a bone of a patient. The pre-revision model of the bone represents a pre-revision state of the bone after a prior orthopedic surgery on the bone. In this example, an orthopedic prosthesis was attached to the bone during the prior orthopedic surgery. Additionally, the surgical assistance system may obtain intra-revision imaging data of the bone. The intra-revision imaging data represents an intra-revision state of the bone during the orthopedic revision surgery after removal of the orthopedic prosthesis from the bone. The surgical assistance system may determine, based on the intra revision imaging data, damaged and intact parts of the bone. The surgical assistance system may then generate a second intra-revision model of the bone by modifying the pre-revision model of the bone to exclude damaged parts of the bone.

Abstract: Disclosed herein are apparatuses and methods for performing joint balancing procedures. The apparatus may have femoral paddle and a tibial paddle attached to a housing. The housing may include a distraction mechanism to vary the space between the femoral paddle and the tibial paddle. The tibial paddle may lie entirely within the femoral paddle in a closed position. A load sensor may be placed in the femoral paddle to measure ligament tension. The apparatus may be inserted into a knee joint and positioned to remain within the knee joint during flexion and extension of the knee without everting a patella.

Abstract: Guides for guiding a tool into a medullary canal of a bone. The guides can include a base and a guide feature. The base can include a first surface configured to contact the bone and a second surface opposite the first surface. The guide feature can be disposed to guide the tool along a central portion of the medullary canal.

Abstract: In some embodiments, the present disclosure relates to a method of securing an implant into a body of a patient. Initially, the implant is placed into the body of the patient. Then, an impactor tool is used to apply a force to the implant. Subsequent to the application of force to the implant, a portion of an impaction pad on an end of the impactor tool is monitored. When the portion is observed to be deformed, the application of force onto the implant is discontinued.

Abstract: A High Energy Beam Processing (HEBP) system provides feedback signal monitoring and feedback control for the improvement of process repeatability and three-dimensional (3D) printed part quality. Signals reflecting process parameters and the quality of the fabricated parts are analyzed by monitoring feedback signals from artifact sources with a process controller which adjusts process parameters. In this manner, fabricated parts are produced more accurately and consistently from powder feedstock by compensating for process variation in response to feedback signals.

Abstract: An implant is produced by fabricating first and second layers. The first layer of repeated and truncated building units is fused together to define pores. The second layer of repeated and truncated building units are fused together to define pores and fused onto the first layer of truncated building units. The first and the second layers form at least part of a porous portion of the implant. The formed porous portion is attached onto a base portion of an implant. The truncated building units of each of the first and the second layers are in the form of spatially overlapping three-dimensional shapes.

Abstract: An example method includes determining, by the one or more processors, an actual orientation of a surgical pin as installed in a bone of a patient; obtaining, by the one or more processors, a planned orientation of the surgical pin; determining, by the one or more processors and based on a comparison between the actual orientation of the surgical pin and the planned orientation of the surgical pin, whether the surgical pin was installed as planned; and responsive to determining that the surgical pin was not installed as planned, outputting, via a visualization device, virtual guidance to assist a surgeon in correcting the installation of the surgical pin.

Abstract: A method of generating a correction plan for a knee of a patient includes obtaining a ratio of reference bone density to reference ligament tension in a reference population. A bone of the knee of the patient may be imaged. From the image of the bone, a first dataset may be determined including at least one site of ligament attachment and existing dwell points of a medial femoral condyle and lateral femoral condyle of the patient on a tibia of the patient. Desired positions of contact in three dimensions of the femoral condyles of the patient with the tibia of the patient may be obtained by determining a relationship in which a ratio of bone density to ligament tension of the patient is substantially equal to the ratio of reference bone density to reference ligament tension.
