There is no consensus for treatment of radial nerve palsy associated with humeral shaft fracture. We reported 3 cases closed humeral shaft fractures in adults that showed sign of radial nerve palsy. The purpose of this study to discuss management strategy, management options and outcome radial nerve palsy associated with closed humeral shaft fracture. Conclusion Radial nerve palsy associated with closed humeral shaft fracture can be treated either by conservative or operative method. There is no significant outcome in recovery and onset to recover between conservative and operative management. The waiting time of 16 to 24 weeks before early exploration is recommended.
