小儿颈椎前半脱位X线测量及其临床意义

X-ray Measurement and its Clinical Meanings of Cervical Vertebra with Anterior Subluxation in Children

为了探讨小儿颈椎前半脱位的X线特点。方法：对1990～1995年收治的14例颈椎前半脱位患儿下颈椎后突节段相邻椎体所成角作了测量。结果：牵引前不稳定椎体间所成角为17．2±4．9°．牵引后此角平均为5．0±2．8°（P＜0.001）。结论：牵引前测定相邻椎体所成角．有助于不稳定椎体的定位诊断；牵引后复测此角．对判断牵引效果及预后评估也有裨益。

Objective: To explore the x-ray manifestation of cervical vertebra with anterior subluxation.Methods:From 1990 to 1995. 14 patients with anterior subluxation of cervical vertebra were treated by cervicaltraction. The angles of relevant adjacent lower cervical vertebra were measured. Results: Before traction, theangles of instablecervical vertebra were 1 7. 2 ±4. 9 °;after traction. the angles were reduced to 5. 0 ±2. 8 °(p <0. 001 ). Concl usions:X-ray measurement of cervical vertebra with anteror subluxation is helpful to making a correct diagnosis and evaluating the treatment effect.
