A method for predicting sagittal balance state of pelvis after hip replacement surgery includes obtaining evaluation imaging data of full body sagittal posture of a patient before surgery under different body postures, and obtaining fixed flexion deformity information of bilateral hip joints and an evaluation result of functionality of hip extension muscle clusters through physical examination. The method includes performing posture analysis on the evaluation imaging data of full body sagittal posture under different body postures obtained to obtain analysis results of degree of sagittal imbalance and severity of hip abduction deformity of the patient before surgery. The method further includes predicting pelvic posture rebalance state in a sagittal plane of the patient after hip replacement surgery according to the analysis results of the degree of sagittal imbalance the severity of hip abduction deformity, and the evaluation result of functionality of hip extension muscle clusters of the patient before surgery.

Prostheses are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses have an integral structure with opposed elongated sections connected by a bridge section. The elongated sections, in some instances, have an unequal length.

Systems and methods for generating a surgical plan for altering an abnormal bone using a generic normal bone model are discussed. For example, a system for planning a surgery on an abnormal bone can include a model receiver module configured to receive a generic normal bone model. The generic normal bone model, such as a parametric model derived from statistical shape data, can include a data set representing a normal bone having an anatomical origin comparable to the abnormal bone. An input interface can be configured to receive an abnormal bone representation including a data set representing the abnormal bone. A surgical planning module can include a registration module configured to register the generic normal bone model to the abnormal bone representation by creating a registered generic model. A surgical plan formation module can be configured to identify one or more abnormal regions of the abnormal bone using the registered generic model.

A system and method for determining patient-specific anatomical parameters to improve surgical outcomes. Some embodiments include processes for predicting the parameters of occluded anatomy. Some embodiment includes processes for more accurately identifying a center point of a ball and socket joint, such as a center point or center of rotation of a femoral head. Some embodiments include processes for identify a patient-specific spinal curvature, including more precisely determining patient specific spinal inflection points. The various steps can be performed automatically through trained computing devices and graphically presented to a surgeon for review and any necessary modifications.

This invention is directed to a wearable device to be worn around a pelvis of an object, comprising: a first compressive element configured to embrace the ASIS and PSIS anatomical structures of the object pelvis; a second compressive element configure to embrace the Ischial Tuberosities and Greater A Trochanter anatomical structures of the object pelvis; at least one sensor for sensing pelvic rotation asymmetry of the object in real time during stride motion; at least two actuators for applying a corrective pressure on at least one PSIS and/or Ischial Tuberosities in real time during said stride motion so as to balance a measured pelvis rotation asymmetry of the object the pelvis rotation; and a control unit configured and operable to receive data in real time from said at least two sensors during the stride motion, calculate the pelvis symmetry based on the data received, and activate at least one of said actuators to apply a corrective pressure upon recognition of a pelvis rotation asymmetry.

A device for determining the location of a pelvis of a person, comprising at least one first pressure transmission element designed for absorbing a sitting pressure/contact pressure exerted by the coccyx/pubic bone of the person and at least one second pressure transmission element designed for absorbing a contact pressure exerted by the sacrum of the person and an evaluation unit, the evaluation unit being designed for performing the following steps: receiving measuring signals from the pressure transmission elements and evaluating them; determining a first characteristic pressure distribution in which, during a rotation of the person's pelvis around his or her horizontal axis, the first pressure transmission element is charged with a sitting pressure of the coccyx or the first pressure transmission element is charged with at least part of the contact pressure of the pubic bone; and determining a second characteristic pressure distribution in which the sitting pressure of the coccyx exerted on the first pressure transmission element exhibits a sudden drop and the contact pressure of the sacrum exerted on the second pressure transmission element exhibits a sudden rise.

An orthopedic system configured for pre-operative, intra-operative and post-operative assessment of a musculoskeletal system. The orthopedic system comprises a first screw, a second screw, a first device, a second device, and a computer. The first screw and the second screw are respectively coupled in a first bone and a second bone of a musculoskeletal system. The first and second screws each include electronic circuitry, one or more sensors, and an IMU. In one embodiment, a first device and a second device can be respectively located in proximity to the first and second screws. The first and second devices respectively transmit a radio frequency signal to the first and second screws. The first and second screws harvest a predetermined amount of energy and then are enabled to perform at least one task and an orderly shutdown. The computer receives measurement data from the first and second screws.

Various systems and methods are provided for surgical and interventional planning, support, post-operative follow-up, and functional recovery tracking. In general, a patient can be tracked throughout medical treatment including through initial onset of symptoms, diagnosis, non-surgical treatment, surgical treatment, and recovery from the surgical treatment. In one embodiment, a patient and one or more medical professionals involved with treating the patient can electronically access a comprehensive treatment planning, support, and review system. The system can provide recommendations regarding diagnosis, non-surgical treatment, surgical treatment, and recovery from the surgical treatment based on data gathered from the patient and the medical professional(s). The system can manage the tracking of multiple patients, thereby allowing for data comparison between similar aspects of medical treatments and for learning over time through continual data gathering, analysis, and assimilation to decision-making algorithms.

A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load, and joint alignment. The system further includes a remote system for receiving, processing, and displaying quantitative measurements from the sensors. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation. The kinetic assessment increases both performance and reliability of the installed joint by reducing error that is introduced by elements that load or modify the joint dynamics not taken into account by prior assessment methods.
