Pronation-Type Galeazzi-Equivalent Fracture: A Case Report.

Fractures of the forearm are common among children and adolescents. Radial shaft fracture with dislocation of the distal radioulnar joint (DRUJ), called Galeazzi fracture, is unusual in pediatrics. The Galeazzi-equivalent fracture is a variant of the classic Galeazzi fracture that occurs in children and adolescents. It is a radius fracture associated with a distal ulnar displaced physeal injury without dislocation of the DRUJ. Our patient was a male, aged 15 years, who visited our emergency department after falling off a scooter onto his left hand. Left wrist X-rays showed a displaced Galeazzi-equivalent fracture. After a trial of close reduction, an X-ray showed a displaced and unstable fracture pattern. The patient was subsequently hospitalized for surgical intervention. Open reduction and internal fixation (ORIF) with a plate and screw were used for the radius fracture. The ulna fracture was irreducible; therefore, ORIF with two crossed smooth Kirschner wires (K-wires) was performed. Complete bone union was achieved, and he had a normal range of motion six months postoperatively. The patient is now able to perform daily and sports activities. At two-year follow-up, complications such as DRUJ instability or joint deformity did not occur. In conclusion, open reduction is desired for patients with malalignment or older patients who have a lower potential for sufficient bone remodeling. Regular serial follow-up sessions are required to assess growth arrest and the occurrence of other complications.
