About

To determine the accuracy of two techniques (transverse scan and sagittal scan) using ultrasonography to identify C7 spinous process compare to the fluoroscope (standard technique)

Full description

To identify the accurate level of upper thoracic spine is essential maneuver during breast surgery and axillary node dissection. Palpation C7 spinous process is most common technique using to identify the level. However, the accuracy was lower than 50%. Ultrasonography has been investigated to identify the cervical nerve roots by differentiating the transvers process of C6 and C7. However, there was no study on the accuracy of using ultrasound to identify cervical spine level before.

20 participants in 3 patient groups

Ultrasound transverse scan

Experimental group

Description:

Transvers scan by identifying the C7 transvers process using vertebral artery and absence of anterior tubercle as a landmark and then scan back following articular process, lamina and then find out the spinous process of C7

Treatment:

Device: Ultrasound transverse scan

Ultrasound sagittal scan

Experimental group

Description:

Sagittal scan by identifying the first and second ribs and scan medially to depict the C7 transvers process.

Treatment:

Device: Ultrasound sagittal scan

Floroscopic technique

Active Comparator group

Description:

Fluoroscopy image will do on lateral view including all cervical spines and upper thoracic spines. C7 spinous process will be identified by counting down from C1 vertebral body and spinous process.

Treatment:

Procedure: Fluoroscopic technique
