青少年特发性脊柱侧弯的分型

curve is larger than or equal to the lumbar

双结构弯(胸弯+胸腰弯:胸弯>胸腰弯或胸弯柔韧性低)
Type 3:单胸弯
Type 4:长胸弯:胸弯常达L2或L3,L4倾斜入胸弯
Type 5:双胸弯:T1或T2倾斜入上胸弯
(Pedicle Screws): 起初是用于腰弯及胸腰弯 (lumbar and thoracolumbar curves) Suk et al.把椎弓根钉用于全脊柱(all level of the spine)
三、侧弯分型
为了更好规范治疗、评价疗效,很 多人开始对脊柱侧弯进行分型。

5. King Ⅴ(双胸弯)
该型为结构性双胸弯。T1椎体倾斜 入上胸弯中。临床上经常见该型患 者左肩高于右肩。往前弯曲时可见 上胸背部左侧及下胸背部右侧凸出。
A type V curve is a double structural thoracic curve .On roentgenograms the first thoracic vertebra is tilted into the concavity of the upper curve, which is structural on side-bending films. Clinical examination frequently demonstrates an elevation of the left shoulder. On forward bending there is an upper left thoracic rib hump and a lower right thoracic rib prominence.

(一).最初由 Ponseti and Friedman 把特发性脊 柱侧弯分成五型,Moe增加了第六型(坎贝尔骨科手 术学 第九版)
1. 单腰弯 (Single major lumbar curve )
2. 单胸腰弯 (Single major thoracolumbar curve)
King IIB型 少于3项
55.9 37.3
46.0
-12.8
1999Asher et al. 在Ibrahim 和Benson 基础上提出KingIIA型必须满足:
1.稳定椎位于T10或更高 2.转向椎位于T11或更高 3.转向椎偏向胸腰弯或腰弯凸侧 4.胸腰段后凸的存在,并且胸腰弯或腰弯顶椎椎弓 根内侧壁偏向侧弯凸侧,胸腰弯或腰弯下端椎倾 斜大于或等于100
脊柱侧弯总的外科治疗目标:纠正结构弯、 避免融合柔韧性好的弯(代偿弯)
(correct the major structural curves and yet avoid fusion of the flexible compensatory curves.)
Harrington: 提出稳定区概念(Stable zone)
果胸弯柔韧度大于腰弯,应按King Ⅰ对待。 但Knapp认为这样患者可以按King Ⅱ对待。
2. King Ⅱ(胸弯≥腰弯)
该型比其他类型争议性都大。
King把该型定义为单胸弯和单腰弯的
混合型。X线上胸弯大于等于腰弯,

腰弯必须超过骶骨中线。在凸侧
bending像上腰弯柔韧性大于胸弯。

1991年Benson 、Ibrahim 提出应将KingII分 为两个亚型。King IIA型
1.腰弯柔软;2.Cobb角<35°;3.矫正率>70%;4. 腰弯顶椎接触到骶骨中线;5.腰骶段侧弯12°

4.King Ⅳ(长胸弯)
该型为长胸弯,L4椎体亦倾 斜入长胸弯中,L5椎体平行于骨 盆。
A type IV curve is a single long thoracic curve, with L4 tilted into the curve and L5 balanced over the pelvis
顶椎位于腰椎
顶椎位于胸腰段结合处
1.King Ⅰ(胸弯<腰弯)
该型最早被认识,因为腰弯 大于胸弯。有时,胸、腰弯相等, 腰弯凸侧bending像上柔韧度小于 胸弯。临床上,腰背部突出大于 胸背部突出。
A King type I curve is recognized easily because the lumbar curve is larger than the thoracic curve .Occasionally, the thoracic and lumbar curves are nearly equal, but the lumbar curve is less flexible on side bending. Clinically, the lumbar rotational prominence is larger than the rib hump.

一、侧弯研究史:
1. 最早开始广泛研究脊柱侧弯 Shands 及 Eisberg 5000例: ≥10度: 1.9% ,≥20度:0.5% 。
2. 1973-1980 Minnesota 147万学生 ≥10度: 1.1%
二、侧弯外科治疗史
1. 20世纪初-50年代末:后路融合+支具
2000年Coonrad 扩展了King 分型(九型:每型都有左侧、 右侧型之分)
Type 1A:
双结构弯(胸弯+腰弯:胸弯<腰弯或腰弯柔韧性低)
Type 1B:
双结构弯(胸弯+胸腰弯:胸弯<胸腰弯或胸腰弯柔韧性低)
Type 2A :
双结构弯(胸弯+腰弯:胸弯>腰弯或胸弯柔韧性低)
Type 2B:
A type III curve is a thoracic scoliosis with the lumbar curve not crossing the midline. The lumbar curve is very flexible on side-bending roentgenograms .On clinical examination the thoracic rib hump is quite apparent, and the lumbar prominence may be quite small or nonexistent.

curves) 】 4. 单胸弯

6.双主弯
特点:
胸弯与腰弯为结构性 角度大致相等 顶椎的旋转大致相同 顶椎的偏离大致相同
如何区别II型弯与双主弯
侧弯位X线片
双主弯中腰弯柔韧性好于胸弯
不等于腰弯结构性成份不如胸弯
胸弯的柔韧性比腰弯差
