A 41-year-old man with a fracture of the upper sacrum and forward and downward displacement of the superior sacral fragment and upper spine on the lower sacrum, developed partial deficit of cauda equina function. Similar fractures rarely have been reported. Signs of lumbar pain, contusion, and fractured transverse processes should lead the surgeon to carefully examine the radiologic fractures of the area of injury; otherwise, this lesion may heal unrecognized. With the spine in flexion, the fracture may create mechanical instability. Early closed or open reduction is theoretically ideal. Surgical treatment must be weighed in terms of the risks and needs of the individual.
一名41岁男性，上骶骨骨折，骶骨上段骨折块及上脊柱向前下方移位至下骶骨，出现马尾神经功能部分缺损。类似骨折鲜有报道。腰痛、挫伤及横突骨折的体征应促使外科医生仔细检查损伤区域的影像学骨折情况；否则，该病变可能在未被识别的情况下愈合。脊柱处于屈曲位时，骨折可能导致机械性不稳定。理论上，早期闭合或切开复位是理想的。手术治疗必须根据个体的风险和需求进行权衡。
