Long Head of Biceps Tendinopathy

Who: Overhead athletes, lifters, and middle-aged adults with a cuff problem they haven't been told about yet.
What: Anterior shoulder pain, often described as running down into the biceps.
How it behaves: Load-related. Worse overhead, worse with resisted elbow flexion and supination, worse carrying.

The one thing to take from this page:

Isolated long head of biceps pathology is close to a rarity. In every arthroscopic series it sits inside a pulley, cuff and labral complex rather than beside it.

The numbers behind that, and they are the spine of everything below:

[1][2][3][4]

Read the denominators. Every one of those figures comes from a shoulder already booked for surgery. Nobody has reported what proportion of anterior shoulder pain on a placement caseload is isolated biceps — that number does not exist.

⚠️ No dedicated guideline exists for this presentation, Australian or international. The closest is the Dutch Orthopaedic Association subacromial pain syndrome guideline, Part 2 [5], which names biceps tendon pathology in scope and whose entire biceps recommendation is one sentence: avoid tenotomy or tenodesis on a healthy tendon unless it is at risk during cuff repair. For conservative management the best available is an expert Delphi at Level of evidence 5.

Pattern > Label. "Biceps tendinopathy" should leave your mouth as a hypothesis, not a diagnosis.

Five stages, in your course's order. Usually insidious, so BEHAVIOUR before HISTORY.

MAIN PROBLEM

The loaded task: bench press, overhead press, throwing, carrying shopping, lifting a toddler.

BODY CHART

• Anterior shoulder, at or just below the front of the joint, often described as travelling down the front of the arm into the biceps belly.
• Ask whether it goes past the elbow — that's a cervical question.
• Clear the ACJ, the cuff and the neck. In this pattern that isn't a formality: the anterior shoulder is crowded, and the odds that the biceps is the sole problem are low.

BEHAVIOUR

• Aggs: overhead, resisted elbow flexion and supination, throwing, carrying, sleeping on it, and long-lever biceps work.
• Eases: unloading the arm, avoiding overhead.
• 24-hr pattern: stiff and sore first thing, easing with movement, building again after a day of lifting or overhead work — the same load-sensitive shape as the cuff it sits beside.
• Night: wakes on rolling onto it, settles once they move off it. Position-easable night pain is mechanical. Unremitting night pain is not — see §4.
• Severity: VAS 0–10 at best / at worst / right now.
• Clicking or catching anteriorly — worth asking about, because tendon instability is one of the few things imaging is genuinely good at (§5).
• Irritability: vigour, severity, time to settle.

HISTORY

• Load change: a new programme, a return to throwing, a volume spike.
• Previous shoulder problems, and what they were told. If a cuff tear or a SLAP lesion is already on the record, the biceps is far more likely to be part of a picture than the picture.
• The three associations with a pathologic biceps in 361 patients with a supraspinatus tear: higher age (p < .0001), higher BMI (p = .018), diabetes (p = .009) [6]. No odds ratios or effect sizes are reported — treat these as associations, not risk figures.

SPECIAL / SCREENING QUESTIONS

General health, diabetes, fever, malignancy history, weight loss, medications, neurological symptoms. See §4.

The subjective's job here is not to confirm the biceps. It is to work out what else is going on.

The isolation problem — this is the page

The differential above is misleading in one important way: these are not alternatives. They travel together.

• A pulley tear was present in 32.4% of 229 consecutive shoulder arthroscopies, was significantly associated with rotator cuff injury (P < .001) and with SLAP lesions, and was torn in all 27 cases of biceps dislocation (Braun 2011).
• In 218 subscapularis repairs, a pathologic LHB with an intact superior glenohumeral / coracohumeral ligament complex was found in only 11% — and even in those, the medial wall of the tendon sheath was torn in 92% (Godenèche 2017).
• LHB pathology was found in 22.4% of 554 shoulders operated on for a cuff tear (Kim 2019).

So when you say "I think this is biceps tendinopathy", the honest completion of that sentence is "…and I should be asking what else is going on in there."

Jones' hypothesis categories that change your plan: sources of symptoms — and specifically, accepting that there may be several — plus precautions and contributing factors (load history).

The biceps rarely hurts alone. Treat the region, not the tendon.
