Suprascapular Nerve Entrapment (Suprascapular Neuropathy) body chart — Illustrative, not diagnostic. Canva body chart for Suprascapular Nerve Entrapment (Suprascapular Neuropathy).

Who: Overhead athletes above all. Volleyball, baseball, overhead lifting, and anyone with high repetitive overhead volume.
What: Compression or traction of the suprascapular nerve, at one of two sites.
How it behaves: Deep, dull posterior/lateral shoulder ache. Weakness in overhead or external-rotation tasks. Eased by rest, worse with repetitive load. Often the athlete notices performance loss before pain.

The one thing to take from this page:

Work out where along the nerve it is, because where tells you what to look for. Both muscles weak points at the suprascapular notch. Infraspinatus alone points at the spinoglenoid notch — and that means go looking for a cyst.

Two sites, two patterns

Lesion site	What is weak	What you should then look for
Suprascapular notch	Supraspinatus + infraspinatus	Anatomy, ligament, load, traction
Spinoglenoid notch	Infraspinatus predominantly	A paralabral / spinoglenoid cyst — and the labral tear behind it

⚠️ There is no guideline here — not Australian, not international. This literature is reviews, case series and surgical cohorts. Everything on this page is a reasoned position from review-level evidence, not a recommendation with trial data behind it.

2 · SE — THE SUBJECTIVE PATTERN (the 70%)

Five stages, in your course's order. The give-away is a weakness story in someone whose neck screen is clean.

MAIN PROBLEM

"My serve has gone."
"There's a deep ache in the back of my shoulder."
"I can't hold the weight out to the side anymore."

Listen for performance loss as the presenting complaint. In overhead athletes it often arrives before the pain does.

BODY CHART

Deep, dull, posterior and lateral shoulder. Poorly localised — patients often cup the back of the shoulder rather than point.
Not dermatomal. Not below the elbow.
Mark where they say the weakness is, not just the pain — it is the more useful mark on this page.

BEHAVIOUR

	Fits neuropathy	Points elsewhere
Aggs	Repetitive overhead load, serving, throwing, pressing	Reaching in daily life only → think RCRSP
Eases	Rest	Nothing helps → reconsider
Symptom	Weakness and fatigue as much as pain	Pain-dominant with near-normal strength → RCRSP
Onset	Gradual, load-related	Severe acute pain then weakness days later → Parsonage-Turner
Distal	Nothing below the elbow	Dermatomal arm pain → cervical

HISTORY

Sport and position. Volleyball attacker, baseball pitcher, overhead lifter — the classic three.
Training volume and recent change.
Has anyone noticed a change in the shape of the shoulder? Ask the partner or the coach. Wasting is often seen before it is felt.
Previous shoulder dislocation or labral injury. Relevant, because of the cyst.
Previous large cuff tear. A massive retracted tear can tension this nerve.

SPECIAL / SCREENING QUESTIONS

Severe pain for a few days, then weakness as the pain settled? That is neuralgic amyotrophy until proven otherwise, not this.
Progressive weakness? Progressive wasting?
Any systemic symptoms, unexplained weight loss, past cancer?
Any numbness? This nerve is motor to those muscles — widespread sensory change points somewhere else.

3 · HYPOTHESIS RANKING

Competing pattern	The one discriminating feature
RC-related shoulder pain / SAPS	Pain-dominant with near-normal strength. This one gives weakness and wasting of supraspinatus and/or infraspinatus.
Cervical radiculopathy	Dermatomal arm pain and a positive cervical screen. Here the cervical screen is clean.
Massive rotator cuff tear	Structural loss of active elevation rather than isolated ER weakness with a tender suprascapular notch.
Parsonage-Turner syndrome	Severe acute pain first, then weakness as the pain settles. A different onset story entirely.
Posterior instability / labral pathology	Apprehension, clunking, a positional story — though it may sit alongside this one via the cyst.

The two that outrank the table

A mass lesion or a space-occupying cyst. Progressive weakness or progressive wasting is not something you keep rehabilitating. It is a reason to image.

Neuralgic amyotrophy (Parsonage-Turner). Severe pain for days, then weakness appearing as the pain fades. Different condition, different pathway.

And the one that isn't a competitor at all

A massive retracted cuff tear can tension or irritate this nerve [1]. So consider neuropathy when weakness or atrophy is out of proportion to the cuff findings you can see — the two coexist rather than compete.

4 · RED FLAGS — DON'T MISS THIS

This section is free, on every pattern, forever. Safety is never gated.

Finding	What it suggests	What you do
Progressive weakness	Ongoing compression, mass lesion	Image. Escalate
Progressive or marked wasting	Established denervation	Image. Escalate
Weakness with no plausible load history	Mass lesion, systemic neuropathy	Medical review
Severe pain for days, then weakness — especially after an infection, vaccination, surgery or childbirth, or with new breathlessness	Neuralgic amyotrophy; nerves outside the plexus, including the phrenic, are commonly involved (Meiling et al. 2024) [21]	Medical review
Weakness spreading beyond supra/infraspinatus	Brachial plexus or cervical cause	Medical review
Night pain unrelated to position, weight loss, past cancer	Malignancy	Medical review
Sensory loss in a dermatomal pattern	Cervical radiculopathy	Reassess the whole picture
A palpable mass	Space-occupying lesion	Image

The rule: load-related posterior ache with weakness that improves as you unload and rebuild is yours. Weakness that is progressing, spreading, or has no load story behind it is not.

Guideline anchor

No Australian guideline covers suprascapular neuropathy, and no guideline of any nationality does — the whole evidence base is reviews, case series and surgical cohorts.

Anchored to the current concept review (Bozzi et al. 2020, PMID 32707860) for the anatomy-to-presentation mapping, the clinical review (Boykin et al. 2010, PMID 20926731) for the diagnostic workup and differential, and the treatment review (Leider et al. 2021, PMID 34745481) for the conservative-versus-decompression decision.

PubMed Source

There is no guideline here at all — not Australian, not international. The literature is predominantly lower-level evidence, and the systematic reviews on this page are reviews of surgical case series, not of controlled comparisons. Treat every management statement as a reasoned position from review-level evidence, not as a recommendation with trial data behind it.
