Abstract Objective To mesure the fracture area of Mason type Ⅱ radial head fractures using three-dimensional reconstruction and compare the relationship with the safe zone.Methods We collected forty patients (31 males and 9 females)，which aged from 18 to 69 years old，with an average of (38±13)years old.The patients were diagnosed of radial head fractures in the Second hospital of Shanxi Medical University between January 2015 and September 2018.The 3D models of radial head fractures were created.We assumed the articular surface of the radial head to be a circal，and the start angle，end angle and fracture area of the radial head were measured by three separate observers in each case，and the data were statistically analyzed.We divided the fitting circle according to a clock face of 360°，with every interval of 10° considered a sector.The averages of the start angle，end angle，fracture area，and bisector angle of the fracture area of the radial head were calculated，and their relationships with the safe zone (110°) were determined.Results We found 30° to 120° as the common fracture area of Mason type Ⅱ radial head fractures，with 39％ (35°) in the safe zone and 61％ (55°) not in the safe zone.No patient had involvement in any sector among the six intervals between 210° and 270°，we considered this area to be the rare fracture area.We regarded the area from 2°~153° as the average fracture area of Mason type Ⅱ radial head fractures.In the average fracture area，42％ (63°) was in the safe zone and 58％(88°) was not.Conclusion Mason type Ⅱ radial head fracture area is mainly located in the anterolateral and anteromedial，while the safe zone is located in the anterolateral and posterolateral.It is proved that the fracture of radial head often involves the unsafe area.It provides intuitive guidance for clinicians to choose suitable therapeutic treatment and internal fixator.
