Problems solved by technology

Quadrangular objects are locked to each other when imported, so these quadrangular objects may not be imported into the space within the cone
Therefore, the disadvantage of the disclosed method is that the object that has been injected into the vertebral body may leak out when stressed, and / or the object to be injected cannot be injected into the vertebral body.

Embodiment Construction

[0042] FIG. 1 shows a bone 4, in particular a vertebral body with an intraosseous space 4a, in a top view. The term "intraosseous space 4a" refers to the entire volume occupied by the bone 4 . In the intraosseous space 4a there is a bone cavity 4b into which the injection cannula 6 opens. Bone cavities 4b can arise, for example, as a result of degenerative events and especially as a result of osteoporosis. The bone cavity 4b can also be artificially created or enlarged using suitable instruments.

[0043] Figure 2 shows a vertebral body 4 with an intraosseous space 4a and a supply device 5 comprising an injection cannula 6 and a pressure applying device 9 comprising an operating handle 9b and a plunger 9c. The injection cannula 6 opens into the intraosseous space 4a, which in this embodiment does not have a bone cavity 4b. In the lumen of the injection cannula 6 and of the pressure-applying device 9, a plurality of biocompatible supports 2 are arranged one behind the other ...

Abstract

The invention relates to dry free-flowing filler (1) for forming a support structure in a bone cavity (4a). Said filler comprises a plurality of biocompatible support bodies (2) which are resistant to deformation or fracture under the physiological loads usually occurring in the bone cavity (4a). Said support bodies (2) have a size between 2 mm and 10 mm and an axis (A) and two opposite abutments (2g) spaced apart in the direction of the axis (A).

Description

technical field [0001] The invention relates to a filler for forming a support structure in an intraosseous space according to the preamble of claim 1 . The invention also relates to a feeding method according to the preamble of claim 25 for feeding a filler into an intraosseous space. The invention also relates to a method for filling an intraosseous space with a supporting structure according to the preamble of claim 31 . [0002] The present invention relates to the treatment of human or animal bones. Background technique [0003] As societies age, the incidence of motion braces of the bones in particular increases in an above-average manner. Bone can be injured or weakened in various ways, for example due to trauma, infection, wear and tear, tumor growth or degenerative diseases such as osteoporosis. Osteoporosis, the so-called depletion of cancellous bone mass, is a problem especially in the elderly, since the weight-bearing capacity of the bones is thereby reduced, ...
