Abstract: This guidance device (100) comprises two vertebral units (110, 120) respectively designed to be fixed to the posterior side of two adjacent vertebrae (1, 2) of the spine. In order to guide these vertebrae stably and effectively in order to reproduce an intervertebral articulated joint between them, these teo vertebral units respectively define substantially spherical complementary articulation surfaces (111P, 121A) which, when the units are fixed to the vertebrae, extend overall on the posterior side of the vertebrae and slide against one another, being centered at one and the same geometric point (C) located in the intervertebral space that separates the vertebrae, while mechanical means (130) limit the amplitude of the relative sliding of the articulation surfaces.

Abstract: The aim of this method is to improve the efficiency and ease of implanting a means for suturing a soft tissue to a bone, while allowing it to be carried out by arthroscopy in particular.

Abstract: The invention concerns a prosthetic mounting clip (1) having a monolithic structure, made of a biologically absorbable plastic material, comprising a distal anchoring element (2) in an anatomical support (8), a proximal stop element (3) relative to a prosthetic part (9), and a connecting rod (4) linking the distal anchoring element (2) and the proximal stop element (3), the connecting rod (4) being arranged relative to the distal anchoring element (2), to determine at least two positions of said connecting rod (4), namely an inoperative position wherein the connecting rod (4) is arranged along a direction (R) relative to the distal anchoring element (2), and another stressed position wherein the connecting rod (4) is folded back against the distal anchoring element (2) along a second direction (P).
