Abstract
The present invention provides a bone anchor, and a method of using the same, the bone anchor comprising a hollow cylindrical housing, buttress means attached to the distal end of said cylindrical housing comprising one or more releasable anchors, a threaded rod rotatably placed within the internal space of said housing, said threaded rod is mechanically linked to the buttress means, wherein said anchors are capable of being moved between an open conformation and a closed conformation and vice versa by means of manipulating the proximal end of said threaded rod.

20. An anchoring device, comprising:
-
a cylindrical housing having a longitudinal axis; at least one support pin placed in said cylindrical housing; and a rod configured for being mechanically linked to said at least one support pin in said cylindrical housing; wherein said mechanically linkage allow said rod to to manipulate an axial extraction of said at least one support pin, from a distal end of said cylindrical housing, substantially along a perpendicular to said longitudinal axis. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. An anchoring device, comprising:
-
a cylindrical housing having a longitudinal axis and distal and proximal ends; at least one support pin placed in said cylindrical housing; a rod configured for being mechanically linked to said at least one support pin in said cylindrical housing; a fixation plate configured for being tightened to said proximal end substantially in perpendicular to said longitudinal axis; wherein said rod is configured for moving along said longitudinal axis to induce and extraction of said at least one support pin from said cylindrical housing via said distal end. - View Dependent Claims (32, 33, 34, 35)

36. A method for bone fixation, comprising:
providing a bone anchor having a cylindrical housing encircling at least one supporting pin and a rod being mechanically linked thereto; drilling a bore in a bone to be fixated between a proximal cortex and a distal cortex; inserting said bone anchor into said bore so that said bone anchor simultaneously traversing said distal and proximal cortexes; and manipulating the rod to induce an extraction of said at least one support pin from said cylindrical housing via said distal cortex, externally to said bone. - View Dependent Claims (37, 38, 39, 40)

41. A method for bone fixation, comprising:
providing a bone anchor having a cylindrical housing encircling at least one supporting pin and a rod being mechanically linked thereto; drilling a bore in a bone to be fixated between a proximal cortex and a cancelous bone segment; inserting said bone anchor into said bore so that said bone anchor simultaneously traversing said proximal cortex and said cancelous bone segment; and manipulating the rod to induce an extraction of said at least one support pin from said cylindrical housing via said proximal cortex, in said cancelous bone segment.
