A study of sectional anatomy with respect to the exposition of brachial plexus in neck area / 中国矫形外科杂志

ABSTRACT

[Objective]To investagate the anatomic features in the approach to the brachial plexus in neck in order to make the exposure of brachial plexus more convenience and safer.[Method]Neck of six embalmed adult cadavers were made serial sectional specimens,which was observed to identify the border,composition and anatomic relation of fat layer between the superficial and deep layer of cervical fascia in the posterior triangle of neck with the brachial plexus.[Result]There was no branches of superficial cervical plexus in the fat layer between the superficial layer and deep layer of cervical fascia below the middle neck,in which there was no important structures except omohyoid muscle and transverse cervical artery.The deep layer of cervical fascia was dense and was directly superficial to the brachial plexus.[Conclusion]Exposure of brachial plexus in the neck would be more safe and convenience upon the understanding of anatomic relatiowship between cervical fascia and brachial plexus.
