3D打印下精准截骨术治疗先天性尺桡关节脱位1例报道

Accurate osteotomy under 3D printing for the treatment of congenital dislocation of radial and ulnar joint:a case report

肘关节由尺骨、桡骨上端及肱骨下端构成,其正常功能对上肢的屈伸和前臂旋转至关重要。尺桡关节脱位影响正常肘关节功能,临床上尺桡关节脱位多为创伤导致,如孟氏骨折、尺骨骨折、桡骨骨折等^([1])。先天性的尺桡关节脱位罕见,有尺骨近端缺如(尺骨棒球手)、尺桡关节融合等[2]。本文病例为双侧桡骨近端过长致尺桡关节脱位。
