• at least one supporting member for implantation into or between a subject's bones;
• and
• an insertion tool configured to guide the at least one supporting member into or between the subject's bones;
• wherein each at least one supporting member comprises a main body having two opposite sides defined respectively as an upper side and a lower side;
• a first connecting portion formed at the upper side of the main body and shaped as a male or female part of a dovetail joint;
• a second connecting portion formed at the lower side of the main body, shaped as the other of the male or female part of the dovetail joint and corresponding in shape to the first connecting portion;
• and
• a guiding structure formed at a side of the main body and configured to mate with the insertion tool;
• wherein a first supporting member of the at least one supporting member is vertically connectable with a second supporting member of the at least one supporting member such that the first connecting portion of the first supporting member is connectable with a second connecting portion of said second supporting member to form said dovetail joint;
• wherein a front side of the first connecting portion further includes a first positioning portion and a front side of the second connecting portion further includes a second positioning portion corresponding in shape and position to the first positioning portion;
• wherein the first positioning portion is a positioning block and the second positioning portion is a positioning hole;
• wherein the insertion tool comprises a plurality of connecting pins, an extension portion, and a grip portion, wherein the extension portion has one end connected to the plurality of connecting pins and an opposite end connected to the grip portion, wherein the extension portion and/or the grip portion comprises a third connecting portion, which is formed on an upper side of the extension portion and/or the grip portion, and is a dovetail projection, and a fourth connecting portion, which is formed on a lower side of the other of the extension portion and/or the grip portion, and is complementary in shape to the third connecting portion dovetail projection;
• and
• wherein the plurality of connecting pins can be correspondingly engaged with the guiding structure of each supporting member.
