A bone binding braid (1, 11, 12) has a braid main body (2). The braid main body (2) is composed of multiple base wires (21). The base wires (21) are woven to form the hollow braid main body (2). Each of the base wires (21) is composed of one or multiple metallic filaments. A penetrating blade (3) is provided at one end of the braid main body (2), and a buckle (4) is provided at the other end of the braid main body (2). When it is intended to bind a breast bone (5) which has been cut, a physician allows the braid main body (2) to pass around the breast bone (5) while incising tissues surrounding the breast bone (5) with the penetrating blade (3). At this time, the braid main body (2) extends in the length direction while keeping the cross-sectional shape of the braid main body (2) in a circular or oval shape. Therefore, the braid main body (2) hardly damages the tissues. Thereafter, when the physician allows one end of the braid main body (2) to pass through a long hole (41) in the buckle (4) and then pulls the one end, the braid main body (2) is pushed against the periphery of the breast bone (5) while further extending, resulting in the deformation of the braid main body (2) into a flat plate-like shape. In this manner, the breast bone (5) can be bound stably.Linvention concerne une tresse de ligature osseuse (1, 11, 12) qui présente un corps principal de tresse (2). Le corps principal de tresse (2) est composé de multiples fils de base (21). Les fils de base (21) sont tissés pour former le corps principal de tresse creux (2). Chacun des fils de base (21) est composé dun ou de plusieurs filaments métalliques. Une lame de pénétration (3) est située à une première extrémité du corps principal de tresse (2) et une boucle (4) est située à lautre extrémité du corps principal de tresse (2). Lorsque lon souhaite ligaturer un sternum (5) qui a été coupé, un médecin permet au corps principal de tresse (2) de passer autour du sternum (5) tout en incisant les tissus entourant
