    Abstract: The present disclosure is for a device for filling the gap (kerf) left in the repair of a craniotomy and the methods for using and manufacturing such a device. The kerf device may be a preparation of demineralized or partially demineralized bone or bone substitute formed into a malleable strip that can be pressed or molded into the opening in between the skull and bone flap in order to allow bone healing without a gap or indentation.

    Abstract: Bolzen mit Außengewinde und einem zylindrischen Bolzenschaft aus allogenem, kortikalen Knochenmaterial für die chirurgisch operative Osteosynthese, wobei es sich bei dem Außengewinde um ein symmetrisches Spitz- oder Trapezgewinde handelt, das zumindest einen Gewindegang pro Millimeter aufweist, und das Knochenmaterial von Osteonen (5) gebildet und mit Havers-Kanälen (6) durchzogen ist. Erfindungsgemäß wird vorgeschlagen, dass die ein Gewindetal begrenzenden Gewindeflanken (9a, 9b) des symmetrischen Spitz- oder Trapezgewindes über einen Gewindetalabschnitt (8) ineinander übergehen, dessen in einem Axialschnitt des Bolzens erscheinende Länge im Bereich von 0.02 mm bis 0.6 mm liegt. Auf diese Weise gelingt es Knochenschrauben (1) mit erhöhter Festigkeit herzustellen, sodass auch weniger geeignetes Spendermaterial für die Herstellung qualitativ hochwertiger Knochenschrauben (1) verwendet werden kann.

    Abstract: Disclosed herein are minimally invasive systems and method for stabilizing the spine, while preserving a degree of spinal flexion and extension of the spine at the level of the stabilized vertebrae postoperatively. The methods can include the steps of, for example, inserting a hollow needle through a central lumen of an introducer cannula into the interior of a first vertebral body, through an intervertebral disc, and into the interior of a second vertebral body adjacent the first vertebral body; inserting an anchor through a central lumen of the hollow needle such that a distal end of the anchor is within the interior of the second vertebral body, a proximal end of the anchor is within the interior of the first vertebral body, and a central portion of the anchor spans the intervertebral disc; expanding the distal end of the anchor within the interior of the second vertebral body; expanding the proximal end of the anchor within the interior of the first vertebral body; flowing a first volume of bone cement media into the distal end of the anchor within the interior of the second vertebral body; flowing a second volume of bone cement media into the proximal end of the anchor within the interior of the first vertebral body; and inserting a flexible rod through the central lumen of the hollow needle, such that a distal portion of the flexible rod is positioned within the interior of the second vertebral body and in contact with the first volume of bone cement media, the proximal portion of the flexible rod is positioned within the interior of the first vertebral body and in contact with the second volume of bone cement media, and a central portion of the rod spans the intervertebral disc, wherein the flexible rod resides at least partially within an interior of the anchor.
