Humeral shaft fractures are relatively common, representing approximately 1% to 5% of all fractures.
Conservative management is the treatment of choice for most humeral shaft fractures and offers functional results and union rates that are not inferior to surgical management.
Age and oblique fractures of the proximal third are risk factors for nonunion. Surgical indication threshold should be lower in patients older than 55 years presenting with this type of fracture.
Functional outcomes and union rates after plating and intramedullary nailing are comparable, but the likelihood of shoulder complications is higher with intramedullary nailing.
There is no advantage to early exploration of the radial nerve even in secondary radial nerve palsy.
