临床发现颈肋综合征的局部病理改变包括颈肋、斜角肌的异常和对臂丛神经的卡压。
The clinical local pathological findings of cervical rib syndrome were the cervical rib, abnormal scalenus and their compression on the brachial plexus.
结果：中斜角肌对臂丛的影响同样重要；
The middle scalene muscle may also influence the brachial plexus.
结论：前、中斜角肌在颈椎横突前、后结节均有起点，该交叉起点可能是上干型胸廓出口综合征的主要原因。
Conclusion:Anterior and middle scalene muscles have starting points in transverse processes of cervical vertebra. Those decussating starting points are the main cause of thorax exit syndrome.
目的观察神经刺激器定位下经斜角肌间沟留置导管用于持续臂丛神经阻滞及术后镇痛的临床效果和可行性。
Objective To evaluate the clinical effects and feasibility of interscalene brachial plexus block and postoperative analgesia using a Nerve Stimulator and a continuous catheter insertion system.
两种手术方式的结局没有明显的差异：切除斜角肌保留第一肋的成功率为75%，两者均切除的为70%。
Results have shown no significant difference between the 2 operations: 75% for scalenectomy without rib resection and 70% for scalenectomy with rib resection.
结果：前斜角肌起于第3 ~6颈椎横突的前后结节，中斜角肌起于第2 ~7或2 - 6颈椎横突的前后结节。
Results: Anterior scalene muscle originates from transverse processes of 3 ~ 6 cervical vertebrae. Middle scalene muscle starts from transverse processes of 2 ~ 7 or 2 ~ 6 cervical vertebrae.
结果：前斜角肌起于第3 ~6颈椎横突的前后结节，中斜角肌起于第2 ~7或2 - 6颈椎横突的前后结节。
Results: Anterior scalene muscle originates from transverse processes of 3 ~ 6 cervical vertebrae. Middle scalene muscle starts from transverse processes of 2 ~ 7 or 2 ~ 6 cervical vertebrae.
