Location

On the upper back, 1.5 cun lateral to the lower border of the spinous process of T4.

How to locate: Count down four spinous processes from C7 to T4 (the one just below T3, which lies level with the medial end of the scapular spine when the arms hang); at the lower border of T4 measure 1.5 cun laterally, onto the crest of the paraspinal muscles.

Distances are in cun, a proportional unit — how to measure.

Skin Skeleton

Needle diagram for the marked point — a schematic section through the skin, not the model.

Technique 1: Oblique (45° to the skin), 0.5–1 cun Direction (source's words): “towards the spine” Scale: 1 cun as WHO 2008 defines it here — Between the bilateral medial borders of the scapula: 6 B-cun; this scale is half of the 6 B-cun between the two medial borders (posterior midline to one border), 3 B-cun. Deadman gives depth in cun, conventionally the patient's own finger-cun. It is drawn here to this region's proportional (B-)cun, so the bar approximates an approximation. Not a depth in millimetres.

Technique 2: Transverse-oblique (about 20° to the skin), 1–1.5 cun Scale: 1 cun as WHO 2008 defines it here — Between the bilateral medial borders of the scapula: 6 B-cun; this scale is half of the 6 B-cun between the two medial borders (posterior midline to one border), 3 B-cun. Deadman gives depth in cun, conventionally the patient's own finger-cun. It is drawn here to this region's proportional (B-)cun, so the bar approximates an approximation. Not a depth in millimetres.

Approximate placement, carried over from our 2D body map onto a single adult male model (BodyParts3D) and checked against the point's location text. Shown on one side of the body. Locate the point on your patient by the location text and palpation, not by this model.

Cun on this part of the body: Between the bilateral medial borders of the scapula: 6 B-cun; this scale is half of the 6 B-cun between the two medial borders (posterior midline to one border), 3 B-cun (WHO 2008, General Guidelines, Proportional Bone (Skeletal) Measurements, p. 12).
Needle angle and depth: Oblique (45° to the skin), 0.5–1 cun, towards the spine. Deadman P, Al-Khafaji M, Baker K, p. 269
Transverse-oblique (about 20° to the skin), 1–1.5 cun. Deadman P, Al-Khafaji M, Baker K, p. 269

The lung is not drawn: the anatomical model used here does not include it as a surface. This is a limit of the model, not of the anatomy. The pneumothorax risk above still applies.

CT-measured mean safe needling depths from Taiwanese adults, by sex and body size (Lin et al. 2013); population-specific and a guide only — adjust to the patient in front of you.

Depths describe average adult habitus in the cited population, never a single safe number for the patient in front of you. Palpate and adjust.
