Abstract: CURRENT CONCEPTS REVIEW SOUBORNÝ REFERÁTnon-union are open fracture types, open surgical revision and postoperative wound infection parallel to the mentioned contributing factors.Fracture non-union occurs as atrophic non-union if e.g.vascular supply to the fracture zone is marginal or potent mesenchymal cells for bony union are too spare.Non-union is then due to a failure of biology as well as inadequate mechanical conditions consecutively.In the case of a hypertrophic non-union mechanical instability is the cause for non-healing of the fracture zone.Another reason for development of a non-union is infection, which will hinder the original fracture zone to heal. Clinical and radiological assessmentFor the definition of non-union in diaphyseal bone a careful clinical and radiological assessment is mandatory.Patients with non-union will describe pain, reduced loading capacity, neurological symptoms if callus of hypertrophic non-unions will compress nerves or even the plexus brachialis.Clinical evaluation should involve documentation of the remaining range of motion.Documentation should respect clinical presentation of the arm or forearm with potential angular deformity of the affected limb, shortening of the limb and state of the soft tissues.Assessment of the vascular potential, presence of movement on stressing the non-union site and range EtiologySeveral etiological factors are contributing to the genesis of non-union.External factors are the severity of the initial injury, comminution of fracture, soft tissue damage and conditions (open vs. closed fracture type), as well as bone loss in open fractures.Internal factors are genetic predisposition, diabetic disease, peripheral vascular disorders, cortisone therapy, mental disorders, smoking and previous skeletal injuries (8,10,19,24,27).Risk factors for the development of an infected Non-Union in Upper Limb Fractures -Clinical Evaluation and Treatment OptionsPaklouby u zlomenin horní končetiny -klinické zhodnocení a možnosti léčby
