Olecranon Bursitis body chart — Illustrative, not diagnostic. Canva body chart for Olecranon Bursitis.

Visually alarming, usually benign, and the two tempting treatments are the two that cause the trouble.

Illness script in one line: a localised, often dramatic swelling over the point of the elbow that hurts far less than it looks, following a knock, a fall, or weeks of leaning on a desk or a floor — with full but uncomfortable end-range flexion and an otherwise normal elbow.

Caseload frequency: common enough that you'll see it on placement. Read further: risk factors in a large-scale population-based study [1], trauma-related cases [2][3], superficial bursitis [4].

The bursa is superficial, and everything you put through the skin costs something

This is the organising idea, and it reverses the instinct. The olecranon bursa sits directly under thin, mobile, poorly vascularised skin with bone immediately behind it. Aspirating it and injecting it both feel like doing something. Both cross that skin.

And the boring option has actually been randomised. Read further: a randomised trial of compression plus non-steroidal anti-inflammatory drugs and other approaches [5], a commentary on it [6], non-surgical treatment of aseptic olecranon bursitis [7], treatment [8].

The reframe:

The instinct	The better position
"It's full of fluid — drain it"	Compression has a randomised trial. Aspiration doesn't fix why it filled
"Inject it and it'll settle"	Long-term follow-up of corticosteroid injection for traumatic olecranon bursitis exists [9]. Ask yourself why that study was needed
The swelling is the problem	The swelling is the symptom. The elbow that keeps meeting a surface is the problem

First-line management, for a reason: activity modification and protective padding.

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

Main problem

"There's a lump on my elbow." Localised swelling over posterior elbow.

Note what they didn't say. Mild ache or pressure pain, usually non-severe. A patient whose main problem is pain rather than the lump is a different conversation — go to section 4.

Body chart

Directly over the olecranon, posterior, well demarcated. Local, and it should stay local. Erythema that extends beyond the swelling is section 4.

Behaviour

Eased by rest and compression. Full but painful end-range flexion (OE line, and it belongs here too — flexion stretches the skin over a distended bursa).

Aggs: leaning on it, full bend, anything pressing on the point of the elbow — a desk edge, a car armrest, a floor, a bench.
Eases: taking the pressure off, compression.
Severity: VAS 0–10 at best / at worst / right now.

Ask specifically what their elbows rest on for hours a day. Desk, car door, armchair, wheelchair, workbench, floor (plumbers, tilers, mechanics, gardeners, students studying). The answer to that question is the treatment.

History

May follow trauma, repetitive leaning, or friction. Three mechanisms, and the third is the one people don't report because friction doesn't feel like an injury.

Ask whether this has happened before. Clinical pearl: recurrent bursitis suggests occupational or mechanical cause. A recurrence is a history-taking failure waiting to be corrected, not a treatment failure.

Special / screening questions

Any fever, chills, or feeling generally unwell? Every time. Section 4.
Any break in the skin — a graze, a scratch, a crack, a shaving nick? Possible redness or warmth (rule out infection).
Gout, pseudogout, rheumatoid arthritis? Pearl from the septic page: always check for trauma + infection + rheumatologic history. The olecranon bursa is a classic site for both gout and rheumatoid nodules, and neither responds to padding.
Diabetes, immunosuppression, steroids, dialysis?
Occupation and hobbies, in detail.

3 · HYPOTHESIS RANKING

Pattern	The one discriminating feature
Aseptic olecranon bursitis	A localised, fluctuant swelling that hurts far less than it looks, with no warmth, no erythema beyond the bursa, and no systemic symptoms.
Septic olecranon bursitis	Warmth, erythema, disproportionate pain, and systemic symptoms — with a skin break in the story. Read further: characteristics and management [10], French recommendations [11]. Its own page, free forever.
Gout or pseudogout	Sudden, exquisitely painful, hot and red, often with a previous attack elsewhere. The olecranon bursa is a classic site. Clinically hard to separate from sepsis — which is why the answer is the same: refer.
Rheumatoid nodule	Firm rather than fluctuant, often multiple, often bilateral, in someone with known or suspected RA. Doesn't respond to padding.
Olecranon fracture	A fall onto the point, focal bony tenderness, and an extension deficit. Its own page.
Triceps tendon rupture	Posterior swelling with a palpable gap and weak or absent resisted elbow extension. Read further: triceps tendon rupture from anatomy to surgical treatment [12]. Rare, missable, and surgical.

The discriminator that does most of the work: is it warm, and can they extend against resistance.

4 · RED FLAGS — DON'T MISS THIS

Free forever. Never gated.

The first pearl is the red flag.

1. Infection — the first pearl

Clinical pearl: rule out infection — look for warmth and systemic symptoms.

Erythema or warmth if septic — medical referral. Antibiotics if septic bursitis suspected.

Escalate the same day if any of these are present:

Fever, rigors, or feeling systemically unwell.
Warmth, compared with the other elbow using the back of your hand.
Erythema extending beyond the bursa, especially a margin that has moved.
Pain out of proportion to the swelling — this presentation is normally less painful than it looks, so "it really hurts" is a change of category.
Any break in the skin in the story, however small.
Immunosuppression, diabetes, long-term steroids, or dialysis.

Do what the septic page says: draw the margin, write the time on it, record a temperature, and refer today rather than review next week. The septic page is free forever — send them there.

The trap: a clear mechanical cause does not exclude infection. The graze from the fall, or the friction that broke the skin over weeks of kneeling, is often how it got in.

2. Triceps tendon rupture

Posterior elbow swelling with a palpable gap above the olecranon and weak or absent resisted extension is not bursitis. Read further: triceps tendon rupture from anatomy to surgical treatment (Celli et al. 2015). Test resisted elbow extension on every posterior elbow swelling. It takes five seconds and it is the one thing that would be catastrophic to miss here.

3. A chronic bursa that has changed character

A long-standing, thickened bursa that develops new pain, ulceration, a non-healing wound, or a change in the overlying skin needs a medical opinion rather than more padding. Chronic olecranon bursitis has been reported as a risk factor for squamous cell carcinoma in a case report [13]. A single case report is not a probability — it is a reason not to keep padding skin that isn't healing.

4. Crystal or inflammatory disease behind it

Sudden, hot, exquisitely painful, or recurrent in someone with gout, pseudogout or rheumatoid arthritis — that is a medical problem with a medical treatment, and padding won't touch it. Refer, and say what you suspect.

Guideline anchor

No Australian guideline, and no clinical practice guideline for the aseptic condition.

The management anchor is a systematic review of non-surgical treatment of aseptic olecranon bursitis (Kaur et al. 2023, PMID 37945181), with treatment systematically reviewed earlier (Sayegh et al. 2014, PMID 25234151) and clinical management reviewed in the Journal of Hand Surgery (Nchinda et al. 2021, PMID 33840568). The single most useful study is a randomised trial in Clinical Orthopaedics and Related Research comparing compression plus NSAIDs against other approaches (Kim et al. 2016, PMID 26463567), published with a CORR Insights commentary (Kennedy et al. 2016, PMID 26493988). For the condition this page exists to exclude, the 2023 French recommendations on prepatellar and olecranon septic bursitis apply (Darrieutort-Laffite et al. 2024, PMID 37995861).

PubMed Source

None of these is a clinical practice guideline for aseptic bursitis, because none exists. The French recommendations govern the septic condition — the thing this page exists to exclude — and are medical, not physiotherapy, documents.
