A computerized model simulates the human spinal cord and makes it possible to draw inferences about the probability of future injury or the likelihood that specific injuries occurred in the past. The spinal cord is modeled by a plurality of two-dimensional graphs formed of a large number of finite elements. The two-dimensional graphs are stacked in positions corresponding to the measured positions of the spinal cord at various vertebral levels of a patient. The stacked graphs yield a three-dimensional model, which may be compared with similar data taken from other patients. The model may include the simulation of stress, applied to all or part of the spinal cord, resulting in a perturbed three-dimensional model which may again be compared with similar data taken from patients having known injuries. The invention can therefore be used, among other things, to verify claims of spinal injury as a result of vehicular or sporting accidents.

The invention discloses a cervical vertebrae and lumbar vertebrae intelligent recovery device. The cervical vertebrae and lumbar vertebrae intelligent recovery device comprises a rectifier, a controller and a massage drug pillow. An automatic control device and a program are arranged in the controller, the controller is connected with the massage drug pillow through an air tube and a wire and controls three indexes of timing, air pressure and temperature in the massage drug pillow for program control, the massage drug pillow forms an arced surface after an airbag is inflated to match with a curve part of a human waist or neck, activity and elasticity of muscle are enhanced by multiple effects such as promoting blood circulation for sterilization by drugs, physiological curvature of vertebra is recovered gradually by physical jacking, jacking of the neck and the waist can be automatically relieved by controlling time, and normal blood supply of a brain is recovered. Sleep and cure of a person are integrated, and accordingly long-term persistence is convenient, a great amount of time can be saved, safety and reliability are achieved without any negative effect, operation is convenient, the person can sleep well and be cured by pressing gently before sleep, clinical practice shows that the cervical vertebrae and lumbar vertebrae intelligent recovery device is evidently effective in prevention and curing of neck and waist diseases caused by modern ways of act.

The present invention relates to a device (2) for determining an optimal placement of a pedicle screw (4). The device comprises a processing unit (14), wherein the processing unit is configured to receive a model data set representing a model surface (22) of a human vertebra model (18) and a pedicle screw model (30) being optimally placed in a span of a pedicle section (28) of the model surface; the processing unit is configured to receive 5 image data representing a surface image (26) of at least one human vertebra (6); the processing unit is configured to adapt the model data set for each ofa number of the at least one human vertebra, such that an adapted model data set representing a correspondingly adapted model surface (36), which fits to the surface image of the respective human vertebra, is provided for each of the number of the at least one human vertebra; and each of the 10 adapted model data sets also represents a correspondingly adapted pedicle screw model (38). The presentinvention further relates to a corresponding method, a corresponding computer program element and a corresponding computer readable medium.

A machine-based learning method estimates a probability of bone fractures in a 3D image, more specifically vertebral fractures. The method and system utilizing such method utilize a data-driven computational model to learn 3D image features for classifying vertebra fractures. A three-dimensional medical image analysis system for predicting a presence of a vertebral fracture in a subject includes a 3D image processor for receiving and processing 3D image data of a 3D image of the subject, producing two or more sets of 3D voxels. Each of the sets of 3D voxels corresponds to an entirety of the 3D image and each of the sets of 3D voxels consists of equal 3D voxels of different dimensions. The system also includes a voxel classifier for assigning the 3D voxels one or more class probabilities each of the 3D voxels contains a fracture using a computational model, and a fracture probability estimator for estimating a probability of the presence of a vertebral fracture in the subject.
