Summary

Typically, the rhomboid minor muscles rise from the C7-T1 spinous process and run downward to touch the upper inner corner of the scapula, and the rhomboid major muscles rise from the T2-T5 spinous process and run downward to reach the lower middle inner corner of the scapula. In anatomical research articles, it has been reported that the rhomboid muscle's anatomical variations are rare. Considering the characteristics of these rhomboid muscles, the investigators planned a study on the utility of rhomboid muscles as a landmark for identifying thoracic spine levels.

Interventions

PROCEDURE

Ultrasound imaging & fluoroscopic confirmation

The researchers use ultrasound to scan the left and right sides of the paravertebral sagittal imaging to identify trapezius, semispinalis, erector spinae muscle, transverse process and rhomboid muscle. The radiopaque marker is attached respectively to the skin of the inferior margin of the rhomboid muscle on the left and right thoracic spinal spines. Then, as the first step for the scheduled nerve block to the patient, thoracic vertebra level verification using C-arm is performed. At this time, left and right level of the transverse process of thoracic spine marked with the radiopaque marker are confirmed and recorded.
