Posttraumatic proximal radioulnar synostosis (PPRUS) is a severe complication of radial head and neck fractures known to occur after severe injury or operative fixation. Cases of PPRUS occurring after minimally displaced, nonoperatively treated radial neck injuries are, by contrast, extremely rare. Here, we present a pediatric case of PPRUS that developed after a nonoperatively treated minimally displaced radial neck fracture with concomitant olecranon fracture. While more cases are needed to establish the association between this pattern of injury and PPRUS, we recommend that when encountering patients with a minimally displaced radial neck fracture and a concomitant elbow injury, the rare possibility of developing proximal radioulnar synostosis should be considered.
创伤后近端桡尺关节融合（PPRUS）是桡骨头和颈部骨折的一种严重并发症，已知在严重损伤或手术固定后会发生。相比之下，在移位极小、非手术治疗的桡骨颈部损伤后发生PPRUS的病例极为罕见。在此，我们报告一例小儿PPRUS病例，该病例发生于非手术治疗的移位极小的桡骨颈部骨折并伴有鹰嘴骨折之后。虽然需要更多病例来确定这种损伤模式与PPRUS之间的关联，但我们建议，当遇到移位极小的桡骨颈部骨折并伴有肘部损伤的患者时，应考虑发生近端桡尺关节融合这种罕见可能性。
