颈椎侧块钢板内固定材料植入技术在颈椎骨折脱位后路治疗中的特点

为探讨颈椎侧块钢板内固定植入技术在颈椎后路手术中的应用情况及特点,在颈椎后路手术中采用颈椎侧块钢板内固定加植骨融合术治疗颈椎骨折脱位患者12例。手术由后正中入路,颈椎骨折脱位根据情况复位,一侧或双侧椎板减压,采用Magerl法进钉,选用3.5mm皮质螺钉,双皮质固定。结果表明,术后3~5个月获得良好骨性融合,颈椎椎间高度无丢失,无螺钉松动及断钉现象,脊髓神经功能有不同程度的恢复。可见颈椎侧块钢板固定植入技术的手术操作相对简单,固定节段短,力学强度好。

Characteristics of internal fixation with cervical lateral mass plate in posterior approach of cervical spine fracture dislocation

To discuss the character and application of internal fixation with cervical lateral mass plate fixation in posterior approach of cervical spine operation. Twelve patients with cervical fracture dislocation treated with posterior cervical lateral mass fixation and bony fusion were selected. The patients received spinal decompression or reduction and decompression according to different diseases. A suitable 3.5 mm bi-cortical screw was inserted using Magerl technique. The results showed that solid bony fusion could be obtained at 3-5 months after the surgery, and the intervertebra heights as well as physiological curves were kept well without screw loosening or breaking. Neurological function was recovered to different extent. Cervical lateral mass plate fixation has the advantages of easily operation technique, wide indications, strong stability and short segment fixation.
