Abstract

An osteosynthetic aid for tubular bones includes a locking nail which has a shank and, at the two ends of said shank, has at least one cross-bore for a headed locking screw. A biasing sleeve is resiliently deformable in an axial direction and is disposed between the head of the locking screw and the shank of the locking nail. The sleeve maintains the cross-locking screw under tension to keep the shank of the nail from shifting during use.
