Axial intramedullary screw (AIMS) for the operative treatment of fractures of long bones in human bone surgery (orthopaedic and traumatology) and veterinary surgery (for large and small animals), characterised by the feature that the osteosynthetic effect of stabilisation is created by the thread of the AIMS cutting into the internal cortical tubular part of the diaphysis of long bones in their axial direction. Application is simplified because of the two - wayness - it possesses two self-tapping tips on both sides and two screwdriver connections on them (3). It may be applied in a single type or in an interlocking type of AIMS for complex multi fragmented fractures. Transverse screws may approach central AIMS with different angles, they may be one-sided, two-sided, with cylindrical conical or threaded for compressive connection or combined (12, 13). AIMS is produced of stainless steel, titanium or resorptive osteosynthetic materials.
