Jianyu (LI15): The Shoulder Bone Point — First Choice for Frozen Shoulder and Arm That Won't Lift

Jianyu: The Front Door of the Shoulder

Jianyu (肩髃, LI15) — literally “shoulder bone” — sits at the front of the shoulder joint itself, in the hollow that opens when you raise your arm. If Jianjing (GB21) is the “shoulder well” at the top of the trapezius, Jianyu is its counterpart at the joint: the point acupuncture reaches for first when the complaint is not just tension but an arm that will not lift.

It belongs to the Large Intestine meridian of Hand-Yangming, but its clinical weight comes from being a meeting point with the Yang Qiao vessel (阳跷脉) — the extraordinary channel that governs muscular activity of the body’s sides. Classical texts summarize its territory bluntly: it treats “the shoulder’s hundred ailments” (主治肩臂诸疾).

Location

• Anatomical location: In the depression below the anterior-inferior border of the acromion (the bony cap of the shoulder), between the deltoid and the tendon of the long head of the biceps
• Easy method: Lift your arm straight out to the side at shoulder height. Two hollows appear at the top of the shoulder joint — Jianyu is the front one. Lower the arm and press: a sore, spreading sensation confirms it.

That “raise the arm and find the hollow” trick is worth memorizing; it distinguishes Jianyu from the posterior hollow (Naoshu, SI10) and is how practitioners locate it on the first try.

Key Functions

1. Frees the Shoulder Joint, Restores Lifting (通利关节)

This is Jianyu’s main work, and the reason it anchors nearly every frozen-shoulder treatment:

• Frozen shoulder (五十肩 / periarthritis of the shoulder) — the middle-aged condition of progressive stiffness, classically named “fifty-year shoulder” because of when it arrives. Jianyu is needled while the patient slowly attempts to raise the arm — the moving-needle technique (motion needling, 动刺法) that pairs stimulation with gentle mobilization
• Shoulder pain that blocks dressing, combing hair, or reaching behind the back — the three classic functional tests physicians ask for
• Post-injury or post-immobilization stiffness — restoring range after the arm has been in a sling
• Hemiplegia aftermath — in stroke rehabilitation, Jianyu appears in protocols for flaccid or spastic arm weakness, paired with Qu Chi (LI11) and Hou Xi (SI3)

2. Dispels Wind-Damp from the Channel (祛风除湿)

The Yangming channel is the “richest in Qi and Blood,” which classically makes its points good hosts for Wind-Damp bi syndrome — the traveling joint aches worse in damp weather. At the shoulder, Jianyu handles:

• Shoulder heaviness as if carrying a wet coat
• Pain that eases with warmth and worsens with cold drafts
• Chronic shoulder trouble that flares every rainy season

3. Treats Rubella and Skin Itching (祛风止痒)

A smaller classical use, drawn from the Large Intestine channel’s relationship with the Lung (skin and surface): Jianyu appears in prescriptions for hives and generalized itching, on the logic of releasing Wind from the Yangming surface. Modern practice treats this as an adjunct, not a primary approach.

How It’s Used

With acupuncture, the classic shoulder prescription pairs Jianyu with its neighbors as a local encirclement: Jianyu + Naohui or Jianliao (Jianliao, SJ14) + Jianjing, plus distal points on the same channel such as He Gu (LI4) — the “same meridian, far and near” structure explained in acupoint categories. Moxibustion on Jianyu suits the cold, damp, stiff type of shoulder; it is skipped in red, hot, swollen joints.

Self-care is acupressure, and it works best combined with movement:

1. Find the front hollow with the opposite hand’s middle finger
2. Press firmly — a sore ache should spread across the shoulder
3. While pressing, slowly circle the arm — ten small, pain-free circles each direction
4. Repeat 2–3 times daily; the pairing of pressure and gentle motion mirrors professional motion-needling in miniature

Warm-up first. Pressing into a frozen shoulder cold, then forcing range, hurts more than it helps.

Cautions

• This point sits near the shoulder joint capsule and, with reckless deep needling, the underlying structures — a practitioner’s point, needled with direction awareness
• Acupressure should stay within comfort; frozen shoulder often needs a staged plan, not forceful self-mobilization
• Night pain, fever with joint redness, or weakness after trauma need medical assessment before any self-treatment — these are not “stiffness” pictures

Key Takeaways

• Jianyu (LI15) is the front-of-shoulder meeting point with the Yang Qiao vessel — first choice for frozen shoulder and an arm that won’t lift.
• Locate it by lifting the arm sideways and taking the front hollow at the shoulder joint.
• Its uses span joint freeing (stiffness, post-injury, post-stroke weakness), Wind-Damp shoulder pain, and adjunct skin-itch treatment.
• Self-care: firm pressure plus slow pain-free circles, daily — motion is half the treatment.
• Red, hot, or post-trauma shoulders need professional evaluation first.
