A tibial component of a knee prosthesis includes a tibial plate and a tibial insert, and anterior and posterior abutments projecting from an upper face of the tibial plate. The anterior abutment extends along at least part of the tibial plate and the posterior abutment extends for at least part of the tibial plate and comprises a part forming a promontory and an anterior cut-out, in particular central, in the form of a window formed in the anterior abutment opening onto the posterior face of the latter opposite the part forming the promontory. The tibial insert has a face upper, a face lower and a lateral face, which has a shape matching the part forming the promontory, characterised in that at least one flexible tab in the form of a hook projects centrally from an anterior face of the insert and locks by snap-fitting, into the anterior cut-out.

A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.

A surgical implant and a surgical kit. The surgical implant has a body portion comprising a first hole formed in an exterior surface of the body portion, a second hole adjacent the first hole, and at least one through-hole within the body portion and extending entirely thought a depth of the body portion extending entirely thought a depth of the body portion. The implant has a central opening abutting the body portion and extending through the body portion. The first hole has a first sidewall and a first cavity in the body portion, the second hole has a second sidewall and a second cavity in the body portion, and the first cavity and the second cavity have an interconnected opening there between. The surgical kit includes the surgical implant and an intervertebral insertion device.

A standalone anterior cervical interbody spacer (ACIF) that includes a spacer body and plate rigidly couple via flexible pins.

Various embodiments of an intervertebral implant comprise a body extending longitudinally along a primary axis, a baseplate, a plurality of elongated arms having a vertebral support surface, the arms being articulated such that the implant has a folded-back position in which the arms are close to each other, and a deployed position in which the arms are moved away from each other, and expansion means between the folded-back and deployed positions, comprising at least two branches pivotably mounted relative to each other and attached to the elongated arms by guide means such that translation of the expansion means parallel to the primary axis causes pivoting of the branches and moves the arms away from each other.
