A clinical case of diaphyseal fracture and nonunion of the humerus

Abstract

A 33-year-old female patient was admitted following a car accident, presenting with a diaphyseal fracture of the humerus (wedge-shaped, intact, classified as type B2 according to the AO classification). Osteosynthesis using a plate was initially performed; however, an incorrect choice of plate thickness led to migration of the metal structure three days post-operation. The causes of this error, diagnostic approaches, and corrective surgical treatment are discussed. To prevent such complications, careful selection of the osteosynthesis method and implant type is essential, along with close attention to the donor site during bone autografting.
