- Instrument set for implant insertion and removal when the treatment has been completed, - Instructions for use (surgical technique). Intramedullary osteosynthesis of humerus provides stable fixation in the following cases: - comminuted fractures of the shaft of the humerus, - severe closed and open fractures of I degree, - pathological fractures, mal-union or non-union of the fragments of the humeral shaft after treatment using other methods. Static method Static fixation is used in multi-fragmental fractures with non-axial stability of bone fragments. Use holes in the distal part of the nail, and one round or both holes - round and oval-shaped - in the proximal part to lock the nail statically. Dynamic method Dynamic fixation may be used in the case of good cortex contact of bone fragments in transverse and oblique fractures, as well as in pseudoarthroses. All distal holes and one oval-shaped proximal hole of the i ntra medullary humeral nail are used in that fixation. Dynamic fixation enables axial movement of bone fragments while loading the limb. In this way, a physiological stimulus is formed to create to create callus and transform it into the lamellar bone. Dynamic method with compression In dynamic fixation with compression (compressive fixation) the compression screw shall be axially inserted into internal threaded hole of the nail shaft in order to put pressure on the screw that locks the nail. The compressive fixation eliminates all micro-movements in the initial stage of fracture treatment.
