Supraspinatus tendinopathy

Anatomy: Supraspinatus and rotator cuff

The supraspinatus arises from the top of the shoulder blade (fossa supraspinata) and runs as a tendon over the head of the upper arm (humeral head) to the large bone ridge (major tubercle). Together with the infraspinatus, subscapularis and teres minor, it forms the rotator cuff. This stabilizes the humeral head centered in the joint and enables precise movements.

• Function: Start of arm separation (abduction) and fine adjustment of shoulder movement.
• Subacromial space: Sliding space with a bursa (subacromial bursa) running between the head of the humerus and the shoulder roof (acromion).
• “Critical Zone”: Area of ​​the supraspinatus tendon with reduced blood flow – prone to degeneration.

Tendons react sensitively to changes in load. Stress that is too high, too fast or monotonous without sufficient regeneration can trigger micro-injuries and remodeling processes (tendinopathy).

Symptoms: How do I recognize supraspinatus tendinopathy?

• Stress-related pain in the side/upper shoulder, often radiating to the upper arm.
• Painful arc when raising the arm between approx. 60-120 degrees.
• Night pain – especially when lying on the affected side.
• Pain during overhead or throwing movements; reduced strength in the starting phase of abduction.
• Occasionally cracking/rubbing (crepitation) if the bursa is also irritated.

Acute deterioration often occurs after unusual overhead work, new training stimuli or a fall on the shoulder. Chronic processes creep in over weeks to months.

Causes and risk factors

It is usually a result of stress and degeneration. Structural tightness under the acromion or calcium deposits can cause additional mechanical irritation to the tendon.

• Overhead Sports: Tennis, Volleyball, Handball, Swimming, CrossFit/Olympic Lifting.
• Occupational/craft work overhead or frequently working at shoulder height.
• Muscle imbalances, scapular dyskinesia, restricted thoracic spine mobility.
• Subacromial tightness (acromion shape, AC joint bone spurs), bursa irritation.
• Metabolic factors: Older age, diabetes, dyslipidemia; Smoke.
• Previous shoulder injuries or partial rotator cuff damage.

Diagnostics: step by step

It begins with anamnesis and clinical examination with functional and provocation tests. The decisive factor is the classification of the complaints: overload, acute injury, signs of bottlenecks or partial structural tears.

• Clinic: Pain localization, painful arch, abduction strength test (e.g. Jobe/“Empty Can”), assessment of scapula guidance.
• Sonography: Dynamic assessment of the supraspinatus tendon, bursa and impingement during movement.
• X-ray: Depiction of calcium deposits, shape of the acromion, AC joint.
• MRI: If the findings are unclear, symptoms persist despite therapy, suspicion of high-grade partial tears/tears or a decision is made to have surgery.

Differential diagnoses: calcified shoulder (tendinosis calcarea), bursitis, partial or complete rotator cuff tear, biceps tendon problems, AC joint arthrosis, cervical nerve root irritation, frozen shoulder.

Conservative therapy: evidence-based and individual

In most cases, structured, conservative treatment achieves the desired result. It combines education, load management, a physiotherapeutic exercise program and – if necessary – time-limited pain modulation.

Expected progression: First improvements often after 4-6 weeks, stable progress within 8-12 weeks. Full resilience - especially with overhead sports - often takes 3-6 months.

Exercises: start safely, increase in a targeted manner

The selection and dosage should be made individually. The following examples are typical building blocks. Pain >5/10 or increasing irritation is a sign to adapt.

• Isometric abduction on the wall: elbows at the sides of the body, keeping light pressure against the wall (5x10-20 seconds).
• Scapula setting: Mild retraction/depression of the shoulder blades, combined with nasal breathing (3×10 breaths).
• Eccentric external rotation with mini band: Slowly return against resistance (3×12–15 per side).
• Lateral raise in the scapular plane (thumb slightly upwards), start with a very small weight or just the arm (3×10–12, low pain).
• Face Pulls/Reverse Rows Light: Focus on scapula control (3×10).
• Thoracic spine mobilization: e.g. rotation in a side position or on a roller (2–3 minutes).

Progression: Increase by 5-10% per week if low-load execution is achieved with little pain. Technology comes before load. Only reintroduce overhead exercises when the basic exercises are stable and low in pain.

Interventional options – when do they make sense?

Interventions can also be considered if pain blocks active therapy or if there are special findings. Decisions are always made individually, and the benefit-risk assessment is transparent.

• Subacromial injection (e.g. low-dose corticosteroids): Can temporarily reduce pain and enable exercise. Repetitions should be limited as tendon quality may be compromised.
• PRP (platelet-rich plasma): An option for selected, treatment-resistant tendinopathies. Evidence mixed; Discuss benefits individually.
• Shock wave therapy (ESWT): Especially for calcific tendinopathy with evidence. Limited effect in non-calcific tendinopathy – considered on a case-by-case basis.
• Needling/Barbotage: Specific for calcification lesions, not routine for “simple” tendinopathy.
• Pain therapy/neural therapy: situational to reduce irritation.

Ultrasound-targeted measures improve precision. Any intervention does not replace active rehabilitation, but can support it in the appropriate time frame.

Surgery: rarely necessary, clearly defined

Surgery is considered if consistent conservative therapy has been unsuccessful for several months, or if there is a high-grade partial/complete tear with loss of function.

• Arthroscopic debridement/partial smoothing for irreparable degeneration with mechanical irritation.
• Tendon suture for high-grade partial/complete tears (individual indication, tissue quality is crucial).
• Selective subacromial decompression only if there is clear mechanical tightness - cautious indication.

Postoperatively, structured follow-up treatment with a phase plan is essential. Depending on the procedure, the complete restoration of resilient shoulder function takes several months.

Course and prognosis

The majority of patients benefit significantly from conservative measures. The healing process is gradual – patience and consistent exercises are key.

• Improvement window: 8-12 weeks for noticeable relief in everyday life; 3-6 months to exercise resilience.
• Favorable: early load adjustment, regular practice, good shoulder blade control.
• Unfavorable: Constant overhead work, nicotine, poorly controlled diabetes, long duration of symptoms before therapy begins.

Prevention: Keep your shoulders strong and resilient

• Increase stress slowly, especially when doing new sports or after breaks.
• Balanced strengthening of the rotator cuff and shoulder blade muscles.
• Regular thoracic spine mobility and stretching routines.
• Workplace ergonomics: screen height, arm rest, breaks.
• avoid smoking; Control metabolic diseases well.
• Technical training in sports, especially in throwing and strength sports.

When to see a doctor? Take warning signs seriously

• Acute shoulder pain after a fall/trauma with an audible crack/snap.
• Significant loss of strength or inability to lift the arm.
• Pain at rest, fever, redness/warmth - suspected inflammation/infection.
• Increasing numbness/tingling down to the hand or radiating neck pain.
• Persistent pain >6-8 weeks despite adjustments and exercises.

Shoulder consultation in Hamburg-Winterhude

In our orthopedic practice at Dorotheenstrasse 48, 22301 Hamburg, we clarify shoulder pain in a structured manner - with discussion, examination and targeted imaging. Together we will determine a realistic, conservatively oriented therapy plan. If necessary, we coordinate cooperation with experienced physiotherapists and carefully discuss additional measures.

We make no promises of healing. Instead, you will receive an evidence-based classification of your findings, clear exercises for everyday life and a comprehensible strategy - adapted to your job, sport and goals.

Common misunderstandings

• “Only absolute protection helps.” – Too much protection weakens the tendon. Dosed activity promotes adaptation.
• “Pain always means harm.” – Pain is a complex signal. Exercise stimuli that are tolerated in moderation are often useful.
• “Cortisone solves the problem permanently.” – It can provide short-term relief, but does not address the cause and should be used cautiously.
• “Surgery is the quickest solution.” – Conservative programs usually achieve their goal; Surgery only if there is a clear indication.
