Osteosynthesis device

摘要

An osteosynthesis device that is used, in particular, for securing joint fragments and for the temporary splinting of toes, more particularly for treating hammer toes or other malalignments of toes. The device comprises a pin with the center axis and the length. The pin consists largely of a bioresorbable material. The pin has at least in one section of the length a non-circular cross-section that is orthogonal to the center axis and has a radius of curvature.

1. An osteosynthesis device comprising a pin having a central axis and a predetermined length defined between a proximal-most rear end and a distal-most front end,
wherein the pin consists of a bioresorbable material selected from the group consisting of a copolymer of lactic acid and glycol acid, a copolymer of poly-L-lactide and poly(DL-lactide-co-glycolic acid), a copolymer of poly-L,D-lactide, and a caprolactone, wherein the pin has a non-circular cross section orthogonal to the central axis over its entire predetermined length, wherein the pin has a core diameter between 1.0 mm and 2.5 mm, wherein a maximum diameter that can be taken through the pin orthogonal to the central axis remains constant over its entire predetermined length, wherein the maximum diameter is between 1.5 mm and 3.5 mm, wherein the pin does not include an enlarged head portion, wherein the pin has, on its peripheral surface, one of (a) at least three longitudinal edges and (b) at least three longitudinal ridges, and wherein the one of (a) at least three longitudinal edges and (b) at least three longitudinal ridges are separated from each other by concave depressions.
