Table 1 The location of emergences of greater occipital nerve (GON) and third occipital nerve (3ON) from the trapezius muscle.
From: Stereotactic topography of the greater and third occipital nerves and its clinical implication
Horizontal distance from Midline (mm) | Vertical distance from external occipital protuberance (mm) | |
|---|---|---|
Emergence of GON on the Trapezius | 22.6 ± 7.4 | 16.3 ± 5.9 |
Emergence of 3ON on the Trapezius | 12.9 ± 9.3 | 44.2 ± 21.4 |
