An intramedullary nail, comprises a proximal portion, a middle portion and a distal portion. The proximal portion has a longitudinal slot and the distal portion has at least one transversal bore. The proximal portion has a longitudinal axis and a longitudinal bore extending over the longitudinal extension of the slot in the distal direction. The longitudinal bore has an internal thread. An insert which is intended to be inserted in the longitudinal bore. The insert comprises a guiding bore in the form of a slot which is intended to receive fixing elements. The alignment of the guiding bore of said insert is transverse with respect to the longitudinal axis of the proximal portion. The insert has a compression screw adapted to be screwed into said internal thread of the longitudinal bore of the proximal portion to move a fixing element in the direction of the longitudinal axis of the intramedullary nail.

Modular intramedullary nail

The tibia nail comprises a tube including a continuous longitudinal bore and includes a proximal anchoring portion with several cross-bores, an adjoining connecting portion which is flexurally resilient in an anterior and posterior direction, a shank adjoining it, and a distal anchoring portion. The anchoring portion is bent away with respect to the shank and has an elongated hole through which a locking screw may be placed. The tibia may be compressed by means of a compression screw inserted into a longitudinal threaded bore. The tibia nail enables retrograde implantation, which has been considered to be impossible for the tibia up to now.

Retrograde tibial nail

An intramedullary nail apparatus comprises a nail having a proximal portion, a middle portion and a distal portion. The proximal portion has a longitudinal slot adapted to receive at least one fixing element and the distal portion has at least one transverse bore. The proximal portion has a longitudinal axial bore. The apparatus further includes a set of inserts, each of which is adapted to be inserted in the longitudinal bore. Each insert has at least one guiding bore, the orientation and position of which is different for each of the inserts. A method of treating fractures utilizing the intramedullary nail apparatus is also disclosed.

The actabular socket supporting ring has a modular construction and is formed of a supporting ring having two securing straps for a cement-free attachment in and on the corresponding bone portions, of a socket cup which is pivotably adjustable in the supporting ring and attachable to the supporting ring by a securing element without the use of bone cement, and of an insert receiving the joint head. The modular construction, and in particular, the pivotable arrangement of the socket cup in the supporting ring, allows a biomechanically optimal alignment of the socket cup, and thus, of the insert receiving the joint ball, and the securing of the socket cup to the supporting ring by a securing element allows an entirely cement-free anchorage of all components.
