Multiple fractures of the atlas and axis are rare. The management of multiple fragment axis fractures and unstable atlas fractures is still challenging for the spinal surgeon. There are no published reports of similar fractures with 3-part fracture of axis associated with an unstable atlas fracture.
We present a patient with concurrent axis and atlas fractures, which have not been reported. The patient suffered hyperextension injury with neck pain and numbness of the bilateral upper extremity associated with weakness after a 2-m fall. The axis fractures included an odontoid type IIA fracture and traumatic spondylolisthesis of C2-C3. The atlas fracture was unstable. The neurological examination manifested as central canal syndrome, which was due to the hyperextension injury of cervical spine and spondylolisthesis of C2-C3. The patient was diagnosed as multiple unstable upper cervical fractures with spinal cord compromise. We performed posterior arthrodesis of C1-C3. Postoperatively, the patient showed neurological improvement, and C1-C3 had fused at the 3-month follow-up.
Posterior arthrodesis of C1-C3 could provide a stable fixation for the 3 parts of axis (an odontoid type IIA fracture and traumatic spondylolisthesis of C2-C3) combined an unstable atlas fracture. Both the patient and the doctor were satisfied with the results of the treatment. So posterior arthrodesis of C1-C3 is a suitable treatment option for the treatment of a concurrent unstable atlas fracture and multiple fractures of the axis.
寰椎和枢椎的多发骨折较为罕见。对于枢椎多块骨折及不稳定的寰椎骨折的处理,脊柱外科医生仍面临挑战。目前尚无关于枢椎三部分骨折合并不稳定寰椎骨折的类似骨折的报道。
我们报告一例同时发生的枢椎和寰椎骨折病例,此前未见报道。该患者在2米高处坠落致颈部过伸伤,伴有颈部疼痛、双侧上肢麻木及无力。枢椎骨折包括齿状突IIA型骨折和C2-C3创伤性椎体滑脱。寰椎骨折不稳定。神经学检查表现为中央管综合征,这是由于颈椎过伸伤和C2-C3椎体滑脱所致。该患者被诊断为多发不稳定上颈椎骨折伴脊髓损伤。我们对C1-C3进行了后路融合术。术后,患者神经功能改善,3个月随访时C1-C3已融合。
C1-C3后路融合术可为枢椎三部分骨折(齿状突IIA型骨折和C2-C3创伤性椎体滑脱)合并不稳定寰椎骨折提供稳定固定。患者和医生对治疗结果均满意。因此,C1-C3后路融合术是治疗同时存在的不稳定寰椎骨折和枢椎多发骨折的合适治疗选择。
