三维CT重建成像在创伤性寰枢椎失稳治疗中的应用

背景：CT三维重建的运用对于复杂的解剖结构如头颈、脊柱、骨盆、四肢的精确评价有确切的作用。目的：观察三维CT重建成像在诊断和治疗创伤性寰枢椎失稳的作用。方法：选择解放军沈阳军区总医院骨科收治的创伤性寰枢椎失稳患者21例，三维CT重建检查，以明确诊断及损伤类型，并依据损伤类型，进行植骨融合内固定治疗。结果与结论：三维CT重建成像可清楚观察寰枢椎失稳惰况，并依据进行内固定，所有病例未出现脊髓、椎动脉及神经根损伤等并发症。全部病例均获得有效随访，随访时间6~15个月，平均9个月。寰枢椎获得骨折愈合和骨性融合，寰枢椎不稳现象均获得有效纠正。提示三维CT重建成像对诊断寰枢椎失稳有较大帮助，并有助于制定恰当的手术方式。

Application of three-dimensional CT reconstruction in traumatic atlantoaxial destabilization

BACKGROUND:The three-dimensional CT reconstruction has an exact role in precise evaluation of complex anatomical structures such as head and neck, spine, pelvis, limbs.OBJECTIVE: Toevaluate the three-dimensional CT reconstruction in diagnosis and treatment of traumatic atlantoaxial destabilization.METHODS:Twenty-one cases of traumatic atlantoaxial destabilization were reviewed. Each case was examined with the three-dimensional CT reconstruction to diagnose and analyze traumatic atlantoaxial destabilization and was operated according to the three-dimensional CT reconstruction images.RESULTS AND CONCLUSION:The three-dimensional atlantoaxial images were reconstructed clearly with the three-dimensional CT reconstruction techniques. According to the three-dimensional images, there was no damage to the spinal cord, vertebral artery and nerve root during operation. All patients got healing of bone fracture and bony fusion during follow-up period (6-15 months, averagely 9 months) and the atlantoaxial destabilization was effectively corrected. It is helpful to diagnose and treat  traumatic atlantoaxial destabilization with the three-dimensional CT reconstruction images.
