Brief Summary

This study aims to define the intermuscular bridges between the scalene muscles at the interscalene groove (around neck area) using high definition US imaging in a cohort of volunteers.

Conditions

Healthy

Keywords

interscalene groove; intermuscular bridges

Outcome Measures

Primary Outcomes (1)

• Identification of the interscalene muscular ridges

  Volunteers will have ultrasound (USG) scanning of both sides of their necks that last for 20 minutes. Images will be recorded as video loops of 7 seconds each that include supraclavicular fossa, C5-7 transverse processes, superior, middle and inferior trunk. After completion of all scannings, newly coded video loops not in a predetermined order or sequence, will be assessed by 3 senior anaesthesiologists and the visualization of the intermuscular bridges at the interscalene groove will be noted. The quality of ultrasound visibility (ultrasound visibility score, UVS) of each structure will be assessed using a 4-point Likert scale (0, not visible; 1, hardly visible; 2, well visible; 3, very well visible). Total UVS (maximum score possible=15) will be calculated by averaging the scores from the three outcome assessors. The percentage of agreement among 3 outcome assessors will be determined by using data on positive identification of the interscalene muscular ridges.

  through study completion, an average of 20 minutes.

Interventions

Ultrasound scan OTHER

Volunteers will have an ultrasound scanning of both sides of their neck lying in supine position. Sequentially the scanning will start from the base of the neck (supraclavicular fossa) to the upper part of the interscalene groove and then in the reverse direction to the supraclavicular fossa. Images will be recorded as video loops.
