The thread spicule comprises a fixing segment, a first support segment and a second support segment, wherein the fixing segment is connected with proximal bone cortex; and the first support segment and the second support segment are used for supporting offside bone cortex and are not equal in length. According to the scheme, the thread spicule comprises the first support segment and the second support segment which are different in length. In an actual operation, the first support segment or the second support segment with a proper length is selected to support the offside bone cortex according to the bone fracture position, so that the thread spicule can be applicable to support different bone fracture parts; the application range of the thread spicule is expanded; and the operation preparation work is simplified.

A pin made of cortical bone may be inserted into adjoining bones of a toe to align and secure the bones. The pin may have barbs to prevent migration of the pin. The pin may include a shoulder to further prevent migration of the pin from the bones, to increase the strength of the pin, and to increase the surface area between the bone pin and the host bone. The pin may further include flattened portions on its circumference to aide in rotating the pin during insertion. The pin may be treated to reduce brittleness.

The invention relates to a novel high-efficiency and easy-to-pull-out bone spicule, include a metal needle body, a levo-polylactic acid needle, an L-polylactic acid sheath and a metal needle handle. The metal needle body is provided with a positioning groove on that front end face and the rear end face, the positioning groove is coaxially distributed with the metal needle body. At least two connecting slots are uniformly arranged on that outer surface of the metal needle. the left-hand polylactic acid needle head comprises a connecting post and a cone head, the metal needle handle comprises aguide post and a tail shank, and the left-hand polylactic acid sheath is a hollow tubular structure coaxially distribute with the metal needle body, and is coated on the outer surface of the metal needle and interconnected with the outer surface of the metal needle through the connecting slot.
