Primary Objective :

To evaluate the incidence of radial nerve palsy for adult patients with humeral shaft fractures

Secondary Objective :

To establish management protocol for traumatic humeral shaft fractures in adults at AUH

Diaphyseal humeral shaft fracture is defined as an extra articular fracture of the humerus with Exclusion of both 5 cm of both upper and lower ends (Muller et al,1990) Within the last Century, many conservative and surgical techniques developed all over the world to solve this problem (Welter D et al, 1991) Conservative treatment was a gold standard since the full research which was published by Sarmiento (Sarmiento, 1977 ) Within the last few decades, with the establishment of osteosynthesis and surgical fixation of long bone which had better outcome in comparison to conservative treatment, it led to a changes in the protocols of treating fractures of the humerus (Muller et al,1990) Within the last decade, with the revolution of biological non anatomical fixation of the humeral shaft fractures, a new era of management was established and became popular all over the highly qualified trauma centres (Balam KM et al, 2014) So, the rational of this work, is to document different surgical strategies of biological fixation of humeral shaft fractures in adults with its results.
