A set of at least two osteosynthesis plates () for implantation, anatomical reduction and internal splinting of bone fragments, in particular after fractures of the distal humerus. The two osteosynthesis plates () according to the invention are provided with drilled holes () which are arranged or formed so that the bone crews () passing through them come to rest in different directions in space, so that bone screws () can pass more completely than in the past through the bone space of the splinted bone ().

Osteosynthesis plate set

A telescopic body for an external bone fixation device includes a central core body and cylindrical outer parts having a bore extending therethrough, all disposed about a center axis. The outer surface of the core body is in the form of a keyed shaft, and the bore in the outer parts has keyways that mate with the shaft, thereby permitting the outer parts to be telescoped in a rotationally fixed, torsion-resistant fashion. Threaded drive spindles housed in the outer parts can be screwed into and out of the core body at either end, permitting the overall length of the telescopic body to be changed. Terminal elements are provided in the ends of the outer parts to limit travel of the drive spindles. At least one of the terminal elements may be a dynamic progression cap which, when progressively unscrewed, allows the axial clamping tension of the threaded spindle to be released in millimeter increments to permit relaxation of the axial clamping of the spindle. The degree of rigidity of the telescopic body as a whole is selectable by suitable choice of materials for each component.

Telescopic body for an external fixation system

An external bone fixation system for clamping bone pins and a connecting element is provided. The system includes a jaw and an upper element for retaining bone pins therebetween, a middle element, and a lower element, with the elements being disposed about a common axis. The upper element swivels relative to the middle element, and the lower element rotates relative to the middle element. A borehole extending through the lower element permits demountable attachment of the device to the connecting element, as well as rotation thereabout. Opposing surfaces of at least two of the elements are positively engageable. The upper, middle, and lower elements are coupled by a common fastener disposed along the common axis, while the jaw and upper element are coupled by at least one fastener that is not disposed on the common axis. A single fastener can be used to arrest two or three degrees of freedom of movement.
