An apparatus and modeling method of the present invention includes the successive steps of generating cartographic data representative of points belonging to a glenoid surface; distinguishing from among the cartographic data a first group of cartographic data corresponding to a first part of the glenoid surface, the first surface part being situated farthest down in the vertical direction in relation to the scapula; calculating from the first group of cartographic data a first ellipsoid portion that coincides substantially with the first surface part; and obtaining a theoretical glenoid surface from the first ellipsoid portion. By virtue of the theoretical glenoid surface obtained by this method, it is possible to assist the surgeon in optimizing the position of implantation of a glenoid component and to produce a glenoid component 'made to measure' for the scapula that is to be fitted with a prosthesis.

Method for modeling a glenoid surface of a scapula, apparatus for implanting a glenoid component of a shoulder prosthesis, and method for producing such a component

This glenoidal component for a shoulder prosthesis comprises a base which may be immobilized on the glenoid cavity of a shoulder, and an element provided to be mounted on this base and forming a convex surface of articulation centred on an axis of symmetry. This axis of symmetry is non perpendicular to a rear face of the base intended to abut against the glenoid cavity, this making it possible to compensate a defect in parallelism between the resectioned surface of the glenoid cavity and the axis of the patient's spinal column. A surgeon can select the component in which the axes of symmetry of the components are oriented differently with respect to their rear faces.

The nucleotomy device makes it possible to produce a nuclear space Es in an intervertebral disc Di using a transosseous approach previously pierced in the body of a vertebra Va. The device includes a tool holder () provided with first connection elements () ensuring the placement of an electric rotary driving motor (), second connection elements () for the placement of a blade cutting tool (), driving elements () imparting rotational and longitudinal translational movements to the cutting tool (), and injection and suction elements () making it possible to evacuate the debris from the nucleus resulting from cutting when it is formed inside the intervertebral disc.

A nucleus implant includes a core () arranged inside a nucleus pulposus space (Es) obtained after nucleotomy of the intervertebral disk (Di) and at least one extension () penetrating inside at least one channel (Co) formed in the vertebral body of the corresponding vertebra (Va, Vb) to strengthen and ensure a connection between the nucleus implant () and the bone body of the vertebra (Va) and/or (Vb) through the diffusion or migration of the viscoelastic material making up the nucleus implant in the cancellous bone of the vertebra.

This glenoidal component for a shoulder prosthesis comprises a base which may be immobilized on the glenoid cavity of a shoulder, and an element provided to be mounted on this base and forming a convex surface of articulation centered on an axis of symmetry. This axis of symmetry is non perpendicular to a rear face of the base intended to abut against the glenoid cavity, this making it possible to compensate a defect in parallelism between the resectioned surface of the glenoid cavity and the axis of the patient's spinal column. A surgeon can select the component in which the axes of symmetry of the components are oriented differently with respect to their rear faces.

The drilling device for forming an osseous channel () with a curved profile () via a straight cannula () previously fixed in the body of a vertebra () with a cortical plateau () of a spinal segment (Sr) of a vertebral column (Cv) includes a guide pin () which is provided from a guide pin kit and has at one of its ends a curved profile () of which the radius of curvature R is less than 20 millimeters, and a sharpened tip () arranged in a direction defined by an angle Y which is less than 90 degrees to the longitudinal axis of said pin, the profile of said guide pin () making it possible to define, after insertion thereof into the body of the vertebra (), two contact points a and b ensuring the guidance of the free end of an articulated drill bit () so as to position said free end in a direction substantially perpendicular to that of the cortical plateau () of the vertebra () to be drilled.

There is provided a posterior lumbar joint prosthesis which includes prosthetic elements reproducing the movements of the joint facets and vertebral anchors which adapt to the variations in the anatomy of vertebra. In use, the prosthesis has lower and upper connectors on each side of the lumbar vertebra. The lower connectors are coupled with, and pivotably mounted onto, respective lower pedicular screws, and a member defining a member axis links lower and upper connectors on each side of the lumbar vertebra. Upon lateral flexion of one of the upper and lower vertebrae relative to the other, each lower connector is capable of multiaxis pivotable movement relative to the respective lower pedicular screws such that each member is capable to pivot with respect to (i) the axis of the lower screw, (ii) a first axis intersecting the lower screw and the lower connector, and/or (iii) an axis intersecting the above first axis and the lower screw, while the member can also move along the member axis.

Disclosed is a polyaxial screw including a friction element () positioned between the head () of the threaded bone anchoring portion () and the head () of the mechanical thread anchoring portion () on the one hand, and a retaining element () ensuring that the anchoring portions () cannot separate from each other while guaranteeing that the anchoring portion with the mechanical thread () is free to move in vertical translation and angular pivoting with respect to the threaded bone anchoring portion () so as to be able to axially preposition the mechanical thread anchoring portion () with respect to the axial anchoring position of the threaded bone anchoring portion ().

The drilling device is composed of an articulated drill () provided with a metal tube () including, along its longitudinal axis XX', and at one of its ends, fixing elements () that cooperate with a device () for driving it in an oscillatory movement, while the other end includes a profile () with a succession of alternately concave and convex loops () ensuring the deformation of the profile along a radius of curvature r, and at least one series of teeth () with cutting edges ().

This glenoidal component for a shoulder prosthesis comprises a base which may be immobilized on the glenoid cavity of a shoulder, and an element provided to be mounted on this base and forming a convex surface of articulation centered on an axis of symmetry. This axis of symmetry is non perpendicular to a rear face of the base intended to abut against the glenoid cavity, this making it possible to compensate a defect in parallelism between the resectioned surface of the glenoid cavity and the axis of the patient's spinal column. A surgeon can select the component most adapted to the orientation of the resectioned surface from a set of components in which the axes of symmetry of the components are oriented differently with respect to their rear faces.
