Although standardized criteria for indications of conservative treatment exist, surgery is often recommended due to its better functional results and shorter rehabilitation period. Intramedullary nailing (IMN) was introduced by Küntscher in 1939 and remains the method of choice for treating these fractures, both closed and open ones, especially because the surgical technique is considered to be simple, standardized and replicable; does not cause major soft tissue damage and allows early loading. This technique is associated with a higher consolidation rate and lower incidence of complications, among which infections are included.
