The present application relates to a prosthesis comprising a flexible portion (1) and at least one less flexible portion (2), which flexible portion comprises a fiber-reinforced hydrogel. In addition to that, the application relates to a prosthesis consisting of a fiber-reinforced hydrogel, which prosthesis is intended to replace cartilaginous materials. The application further relates to the use of the prosthesis and to a method for manufacturing the prosthesis. The application furthermore relates to a method of preparing the flexible portion for a prosthesis. Finally, the application relates to a fiber material apparently intended for use in the prosthesis.

A vertebral-column device that is suitable to be received in an intervertebral space between two dorsal vertebrae, the prosthesis comprising a curved strip of biocompatible material. The width of the strip being such that after placement, the strip makes contact with the vertebrae. The strip is manufactured from a material that can undergo great deformations before permanent deformation arises. The strip is curved in a shape in which the extremities are situated apart from one another and the radius of the curved parts and the thickness of the strip are chosen in such a way that when the strip is bent out into an approximately straight strip, scarcely any permanent deformation arises. Thus, the strip which has been bent out into an approximately straight strip is capable of being introduced into an intervertebral space where the strip assumes its original curved shape.

A method and an X-ray apparatus for imaging anatomical parts of the human anatomy, in particular for imaging the human spine. In order to improve the quality and the diagnostic value of projection images of the anatomical parts the invention acquires at least one initial projection image of at least the region of interest of the anatomy, to determine the positions and/or orientations of the anatomical parts in the region of interest from the at least one initial projection image and/or from other sources of information, to determine the optimum imaging parameters for the anatomical parts from their positions and/or orientations, and to acquire images of the anatomical parts while using the optimum imaging parameters. The complexity of the scene and the mixture of over-projecting structures limiting the diagnostic reliability of the projection images are thus taken into account. In a preferred embodiment a scanning trajectory is determined while using the information of the at least one initial projection image along which the source-detector unit is moved while acquiring the projection images of the spine.

The invention relates to a corset for the treatment of a patient suffering from a back complaint, such as scoliosis, comprising a lower part to be supported by the hip, and an upper part to be fitted around the patient's chest. There is a flexible coupling provided to connect the lower part and the upper part. Both the lower part and the upper part are provided with an adjustable springy element to enable the lower part and the upper part to apply a pressure force on the patient's body.
摘要:
An instrument in particular suitable for being inserted into the cavity within a vertebra, which instrument features a collapsed position and an expanded position, in which collapsed position the instrument can be inserted into the cavity through an opening in the vertebral wall. The instrument includes a first upper elongated contact element and a second lower elongated contact element, and member for moving said elements apart in a direction substantially transversely to their contact surfaces to a particular end position, in which the elements are locked in position relative to each other.
