Abstract: An osteosynthetic aid for tubular bones includes a locking nail which has a shank and, at the two ends of said shank, has at least one cross-bore for a headed locking screw. A biasing sleeve is resiliently deformable in an axial direction and is disposed between the head of the locking screw and the shank of the locking nail. The sleeve maintains the cross-locking screw under tension to keep the shank of the nail from shifting during use.

Abstract: A targeting system has a targeting device for a locking nail which is proximally provided with cross-bores the axes of which are disposed in an offset relationship from each other by predetermined distances and/or by predetermined angles. The apparatus has a target arm having at least one target bore and a holding device mounted on the target arm to engage the distal end of the nail. The holding device has a reception bore in which a retaining or locating bar is guided. The locating bar extends in parallel with the target arm and generally perpendicular to the cross-bore. The locating bar has fasteners to fix it to the nail. The retaining bar has several recesses in the area of the reception bore. The reception bore has associated therewith a radially movable locking element or detent element which can be moved into engagement with one of the recesses by use of a handle to locate the axial and rotational positions of the retaining bar in the reception bore.

Abstract: A device for installation of a guide wire for a drilling tool in a correct positional arrangement in a bone. The device includes a tissue protection sleeve, which has at one end a laterally projecting grip or handle. A trocar is provided, which trocar can be introduced into the tissue protection sleeve from the handle end and whose other end is closed. The trocar is rotatable in the tissue protection sleeve and has a central bore hole and a plurality of eccentric axially parallel bore holes, through which a guide wire can be passed. A second handle is provided which extends approximately in the same direction of the first handle and whose one end engages the end of the trocar situated the outside of the tissue protection sleeve, so that the normally freely rotatable trocar is fixed in the direction of rotation relative to the tissue protection sleeve, when both handles are manually clamped against each other.

Abstract: An implantation device and method for applying the same has an implantation device for implantation in a target structure such as a bone. The implantation device comprises a shaft region, wherein the shaft region has at least one protrusion. The protrusion comprises a material which is modifiable by using mechanical energy. In particular, the modifiable material may be liquefiable and/or shearable by the mechanical energy. Preferably, the material may be adapted in such a way that the modifications may be achievable by a mechanical energy input which does not destroy human tissue.

Abstract: An implantation device for implantation in a target structure such as a bone includes a base region. The base region includes a connecting portion, wherein the connecting portion is adapted to interact with a coupling region of a handling device. In particular, the connecting portion and the coupling region may be engageable with each other. The device may be polymeric and is capable of being softened by mechanical energy such as sound energy.

Abstract: An aiming device for a locking nail has a first portion detachably connectable with the exposed end of the nail. An aiming arm is connected to the first portion, which, in turn, is connected to an accommodation arm portion which runs approximately parallel to the nail. The accommodation portion has at least one transverse bore for receiving a guiding sleeve. The accommodation portion being provided with a locking portion which is movable in relation to the accommodation portion against a spring force, with the transverse bore being approximately aligned towards an opening in the locking portion. The transverse bore and the opening being disposed such that when the locking portion is relaxed an accommodated guiding sleeve is held slightly clamped and the sleeve is freely movable in a position locking upon a movement of the portion against the spring force.

Abstract: A humeral nail for the surgical care of fractures of the proximal humerus, with a shaft which has a longitudinal axis and is provided in a proximal portion with at least transverse bores spaced apart in the axial direction. The axis of the three bores is circumferentially offset in respect to each other in planes perpendicular to the longitudinal axis of the shaft. The nail is provided with at least two additional transverse bores in a portion located towards the distal end of the nail, the proximal transverse bore running diagonally to the longitudinal axis and being located in the same plane as is the axis of the additional transverse bores.

Abstract: An implant for osteosynthesis, for example a bone nail, has an implant body which has at least one bore with a threaded portion and a bone screw which engages the thread when it is threaded into a bone for the fixation of the implant body. The threaded bore has an annular groove the diameter of which is larger than the thread outer diameter, and which receives a ring of a deformable material with an inner diameter which is smaller than the outer diameter of the thread of the bone screw so that the ring extends partially into the bore.
