Abstract: The invention concerns a system for partially cutting a bone, comprising a device for guiding a cutting tool. According to the invention, the device comprises: —an upper face forming a mechanical stop for a first part of the cutting tool, the upper face being non-cutting and thicker than the blade, so as to limit the insertion of the blade into said bone in order to partially cut said bone, the upper stop face having a profile that is a homothety of the edge profile of said hinge, the guide device having a pre-defined range to ensure the steering of the blade of the cutting tool in a pre-defined direction of partial cutting of the bone, —a second part that fastens to the bone and a first fastening means for fastening the guide device to the second part and —a means for adjusting the orientation of the guide device relative to the second part.

Abstract: The invention relates in particular to a system for attaching a first bone segment to a second bone segment, the two segments belonging to the same bone, in which the first and second segments are held together via a hinge resulting from the partial transverse cutting of said bone, characterized by the fact that said system comprises: two targets suitable for attaching to the two segments of said bone; a navigation system suitable for acquiring the three-dimensional positions and orientations of the targets; —a processing system suitable for calculating, based on the data sent from the navigation system, the angles corresponding to the three-dimensional alignment of said two segments; a display unit suitable for displaying the information to the surgeon; at least one milling guide; a plurality of implants of different sizes.

Abstract: An osteosynthesis device is provided. The device includes a first screw for attaching a first holding base to a first section of a bone, a second screw for attaching a second holding base to a second section of the bone, and a rigid linking element mutually connecting the first and second bases. Either the first screw or the first base has a cavity for receiving a bracket of an associated position-marking device.

Abstract: The invention relates to a mixture for the production of a vat-dyed amber glass; an amber glass formed from the vitrifiable mixture, based on a silico-sodo-calcic composition; and a method for the production of tubes and blanks (2) for bulbs (1) using said glass. The mixture contains 100% by weight of the following ingredients: 0.01%-1% by weight molybdenum bisulphur and 0.01%-7% strontium sulphur by weight. The glass thus obtained is devoid of harmful products such as cadmium and no additional heat treatment is required in order to obtain the desired colour thereof.

Abstract: The invention relates to a bulk-tinted red glass formed from a glass batch based on a soda-lime-silica composition, to a process for manufacturing red glass and to a bulb obtained from a blank or a tube manufactured with such a glass. The batch comprises, per 100% by weight of the batch, 0.1 to 1% by weight of copper, 0.2 to 2% by weight of tin and 0.01 to 2.5% by weight of oxide of the lanthanide group and/or 0.01 to 0.5% by weight of silver in silver oxide or nitrate form.

Abstract: Method for selecting one or several knee prosthesis elements, by acquiring spatial data concerning spacing and tensioned femorotibial position, including the corresponding HKA angle, for at least three angular positions, of 20°, of 0°, and of the order of 90° in flexion, processing the data thus obtained to verify whether the HKA angles are substantially equal and included within the tolerable limits, and processing the data, in particular those corresponding to extension and flexion of 90° to determine the dimensions and/or positions of the implant.

Abstract: A bone nail for the medical care of spoke bone (i.e., radius) fractures comprises a hollow shaft (10) curved in a plane, which shaft is to be distally and posteriorly inserted into a spoke bone medullary canal and which includes a proximal end portion which is slotted so as to be able to be spread apart by a spreading body. A straddling member (36) having an outer threaded portion (44) cooperates with an inner threaded portion (18) in the slotted portion (12) of the shaft (10) of the nail so as to radially expand the proximal nail end when the straddling body (36) is rotated. A cross bore (22) at the distal end of the shaft (10) receives a bone screw extending approximately vertical to the plane of the curvature.
