摘要
通过对 46例 X线片进行 cobb' s角钉杆角及 CT片椎管矢径的测量 ,结果显示 :钉杆角是椎体复位的关键 ,α角 +β角≥ 180°对后凸畸形 cobb' s角矫正明显。对椎体前柱的复位单靠器械杠杆的力量是不足的 ,同时还应依靠俯卧位胸腰段背伸牵引力量。Steffee手术固定可使椎管显著增大。术中有效植骨对维持 Steffee手术效果有重要意义。
The Cobb's angles and screw rod angles on X ray film and the sagittal diameter of vertebral canal on CT film in 46 cases were measured. The results indicated that Screw rod angles were important for reduction, α angles + β angles ≥180° had better results when corrected for cobb's angles in kyphosis. The corrction of the anterior column of vertebra was not enough to depend upon only on the mechanic strength of level. It should mainly rely on the strength produced by the over stretch of the Thoraco Lumbar region in the prone position. With the use of Steffee's fixator, the vertebral canal would be widened significantly. For embedding. done in the operation, it is protant to keep the effect of steffee operation.
