The humeral nail comprises a nail longitudinal axis extending from the proximal portion to the distal portion, a first proximal through hole defining a first threaded trajectory, a second proximal throughbore defining a second threaded trajectory , A third proximal through hole defining a third screw trajectory, a descending through hole defining a descending screw trajectory, and a distance through hole defining a range trajectory. The first, second and third threaded tracks extend across the nail longitudinal axis and the descending screw trajectory extends from the anterior to the posterior and from the proximal to the distal path trajectory from the distal to the proximal, from the anterior Behind, and from the outside to the inside. In some embodiments, the through hole defines at least two screw thread trajectories.(FIG.上腕骨用釘は、近位部から遠位部に延びる釘長手軸線と、第1のねじ軌道を定める第1の近位貫通孔と、第2のねじ軌道を定める第2の近位貫通孔と、第3のねじ軌道を定める第3の近位貫通孔と、下降ねじ軌道を定める下降貫通孔と、及び、距ねじ軌道を定める距貫通孔とを含むことがある。第1、第2、及び第3のねじ軌道は、釘長手軸線を横切って伸び、下降ねじ軌道は前方から後方及び近位から遠位に伸び、距ねじ軌道は遠位から近位、前方から後方、及び外側から内側に延びる。一部の実施例では、距貫通孔は、少なくとも2つの距ねじ軌道を定める。【選択図】図1E
