Abstract: The present invention relates to a medical instrumentation for implanting an acetabular cup, comprising at least one medical guiding instrument for a first reaming tool, wherein the guiding instrument comprises a shaped body, wherein the shaped body has a patient-specific bone abutment surface facing in the distal direction and deviating from a spherical surface section, wherein the bone abutment surface is shaped so as to correspond or substantially correspond to a bone surface of the patient, and wherein a guiding shaft, defining a longitudinal axis, for guiding the first reaming tool protrudes from the shaped body and faces in the proximal direction.

Abstract: The present invention relates to a method for the generation of chondrons and of cartilaginous tissue. In particular, the present invention relates to the ability of Mg ions to stimulate the growth and regeneration of chondrons, particularly of pseudo-chondrons as an intermediate in the regeneration and growth of cartilaginous tissue. Especially, Unphysiologically high extracellular concentrations of Mg are able to regenerate hyaline cartilage, elastic cartilage and/or fibrocartilage via the intermediate form of chondrons.

Abstract: The use of a magnesium substance, whose corrosiveness is altered as a result of modification with halogenides, enables medical implants, prostheses or prosthesis parts and medical instruments, devices and auxiliary contrivances, especially surgical instruments or tools, for use in and on the human or animal body to be produced, whereby the degree of corrosion-resistance thereof can be adjusted to full corrosion-resistance.

Abstract: The invention provides a method of enhancing the healing of bone fractures in an animal subjected to distraction osteogenesis, the method comprising administering, to the animal in need thereof, a growth hormone or a growth hormone secretagogue in an amount sufficient to provide bone formation simultaneous with the distraction procedure.
