Abstract:
Objective To test using musculoskeletal ultrasound (MSUS) to observe uncovertebral joints (UJs) and to explain the ultrasound images of UJs and their adjacent tissues,especially the vertebral artery (VA).Methods MSUS was used first with human skeletons and cadavers to localize the UJs and VA on the MSUS images with the aid of implanted needles.MSUS was then used with a patient clinically diagnosed with cervical spondylosis of the vertebral artery type (CSA) to detail the image of a normal UJ and its relationship with the adjacent tissues,especially the VA.Whether there was a lateral spur from the uncinate process (UP) was assessed to try to establish a method for measuring osteophytes.Results During the examination the patient was in supine,the neck was elevated 15cm with a pillow and was at 45 degrees of rotation to the contralateral side.The probe was placed at the medial border of the sternocleidomastoid muscle.When the longitudinal section of the common carotid artery was shown,the probe was slowly moved laterally until the VA first appeared,and then was moved up along the VA.Once the VA entered the transverse foramen,moving the probe slightly allowed the UJ behind the VA to be seen between two transverse processes.The UJ thus lies between two transverse processes,that is,between the lateral margins of two vertebral bodies and outside the intervertebral disc.The echo of the lateral border of the UP is on a straight line with the echo of the lateral margin of the vertebral body,with the VA in front of the line.It was noticed that the image of a UP with lateral osteophyte formation crossed the line and reached closer to the VA.The transverse diameter of the UJ was measured as the distance from a line cutting the lateral cortical margin of the cervical vertebra to the outer cortical margin of the lateral UP.Conclusion MSUS can clearly show the UJ and its adjacent tissues,especially the VA.It can be used to assess and measure UJs with lateral osteophyte formation.
