This condition is most common in individuals who perform repetitive overhead activities—especially athletes in sports such as horse racing, baseball, swimming, and weight‑lifting—hence the colloquial name “jockey’s shoulder.” However, it also occurs in non‑athletes who engage in repetitive lifting or have underlying shoulder degeneration.

• Who it affects: Adults aged 30–60, with a slight male predominance (≈55 % of cases). Competitive jockeys have reported incidence rates up to 12 % per riding season, while the general population prevalence is estimated at 2–5 % of all shoulder complaints (Mayo Clinic, 2023).
• Typical onset: Insidious, developing over weeks to months after repetitive overhead motion or a single traumatic event.

Symptoms

Symptoms can vary from mild ache to severe disabling pain. Common features include:

• Shoulder pain: Dull, aching pain localized over the top of the shoulder that may worsen with overhead activity.
• Pain at night: Discomfort that disturbs sleep, especially when lying on the affected side.
• Reduced range of motion: Difficulty lifting the arm above shoulder level (abduction) or reaching behind the back.
• Crepitus: A grating or clicking sensation felt when moving the arm, caused by inflamed bursal tissue rubbing against bone.
• Swelling or warmth: Occasionally visible puffiness over the acromion; the skin may feel warm to touch.
• Weakness: Perceived loss of strength, especially during pushing or pulling motions.
• Pain with palpation: Tenderness when pressing on the lateral edge of the acromion.

While most cases are painless at rest, persistent symptoms beyond 6 weeks warrant a professional evaluation.

Causes and Risk Factors

Primary Causes

• Repetitive overhead motion: Activities such as horse riding, painting, throwing, or swimming cause micro‑trauma to the subacromial bursa.
• Acute trauma: A fall onto the outstretched arm or a direct blow can trigger inflammation.
• Shoulder impingement syndrome: Narrowing of the subacromial space (e.g., due to a hooked acromion) predisposes the bursa to irritation.
• Rotator‑cuff pathology: Tears or tendinopathy increase friction against the bursa, leading to secondary bursitis.

Risk Factors

• Occupations or sports that involve repetitive arm elevation (jockeys, baseball pitchers, swimmers, carpenters).
• Age‑related degenerative changes in the shoulder.
• Previous shoulder injury or surgery.
• Systemic inflammatory conditions (e.g., rheumatoid arthritis, gout) that can involve bursae.
• Poor posture or scapular dyskinesis that reduces the subacromial space.

Diagnosis

Diagnosis is primarily clinical, supported by imaging when needed.

History & Physical Examination

• Detailed activity history (frequency of overhead work, recent trauma).
• Inspection for swelling or deformity.
• Palpation of the acromion and deltoid insertion.
• Range‑of‑motion testing: painful limitation of abduction beyond 90° is typical.
• Special tests: Neer and Hawkins‑Kennedy impingement tests often reproduce symptoms.

Imaging & Tests

• Ultrasound: Real‑time visualization of fluid collection in the bursa; can assess rotator‑cuff integrity (CDC, 2022).
• X‑ray: Rules out bony abnormalities, calcific tendinitis, or osteoarthritis.
• MRI: Gold standard when a rotator‑cuff tear, labral pathology, or chronic impingement is suspected.
• Diagnostic injection: Ultrasound‑guided injection of a local anesthetic into the bursa; temporary pain relief confirms the diagnosis.

Treatment Options

Management follows a stepwise approach: conservative measures first, followed by interventional therapies if needed.

1. Medications

• NSAIDs: Ibuprofen 400‑600 mg every 6–8 h or naproxen 250‑500 mg BID reduces pain and inflammation (Mayo Clinic, 2023).
• Acetaminophen: For patients who cannot tolerate NSAIDs.
• Corticosteroid injection: A single dose of 40‑80 mg methylprednisolone mixed with local anesthetic provides relief in 70‑80 % of patients within 1–2 weeks. Repeat injections are limited to ≤3 per year due to cartilage risk.
• Topical NSAIDs: Useful for mild cases or as adjunctive therapy.

2. Physical Therapy & Rehabilitation

• Phase 1 (0‑2 weeks): Rest, ice 15 min 3‑4×/day, gentle pendulum exercises.
• Phase 2 (2‑6 weeks): Stretching of the posterior capsule (cross‑body stretch), scapular stabilization (serratus anterior, lower trapezius), and rotator‑cuff strengthening (external rotation with theraband).
• Phase 3 (6‑12 weeks): Progressive functional training, sport‑specific drills, and proprioceptive work.

Therapists often employ manual techniques (soft‑tissue mobilization, joint glides) to improve subacromial space.

3. Activity Modification

• Temporary reduction of overhead activities (e.g., limit riding sessions, avoid throwing).
• Ergonomic adjustments: use of a shoulder brace or a “throwing‑arm harness” for jockeys can offload stress.

4. Procedural Interventions

• Aspiration: Removal of excess fluid if the bursa is markedly distended.
• Barbotage (needling): Repeated needle puncture to break up inflammatory tissue.
• Subacromial decompression surgery: Indicated when conservative care fails after 6 months and imaging shows impingement or rotator‑cuff pathology. Arthroscopic bursectomy and acromioplasty have success rates >85 % (Cleveland Clinic, 2023).

5. Lifestyle & Home Measures

• Ice packs for 15‑20 minutes after activity.
• Over‑the‑counter NSAIDs as directed.
• Regular shoulder‑stretching routine (e.g., doorway stretch, sleeper stretch).
• Maintain a healthy weight—excess adipose tissue can increase shoulder strain.

Living with Jockey’s Shoulder (Subacromial Bursitis)

Even after pain subsides, many patients need ongoing strategies to prevent recurrence.

• Daily shoulder warm‑up: 5‑minute dynamic routine—arm circles, scapular retractions, and light band work—before any overhead task.
• Strength maintenance: Perform rotator‑cuff and scapular exercises 2–3 times per week for life.
• Posture awareness: Keep shoulders relaxed and thoracic spine neutral; consider ergonomic chairs or saddle‑type seats for riders.
• Gradual progression: Increase intensity or duration of activity by no more than 10 % per week.
• Self‑monitoring: Keep a symptom diary; note activities that trigger pain and adjust accordingly.
• Professional follow‑up: Schedule a check‑up with your orthopedic or sports‑medicine clinician at 3‑month intervals during the first year of recovery.

Prevention

Prevention focuses on keeping the subacromial space open and avoiding repetitive micro‑trauma.

• Strengthen the rotator cuff and scapular stabilizers: External rotation, prone Y/T/W exercises, and wall slides.
• Flexibility training: Posterior capsule stretch, pectoral stretch, and thoracic extension exercises.
• Technique optimization: For athletes—work with a coach to ensure safe throwing, swimming, or riding mechanics.
• Equipment modification: Use padded saddles, appropriate reins, or a shoulder brace that limits excessive abduction.
• Regular rest periods: Incorporate scheduled “off‑days” to allow tissue recovery, especially during intensive training blocks.
• Manage systemic conditions: Keep rheumatoid arthritis or gout under control; these diseases can involve bursae.

Complications

If left untreated, subacromial bursitis can evolve into more serious shoulder pathology:

• Chronic impingement syndrome: Ongoing inflammation narrows the subacromial space, causing rotator‑cuff wear.
• Rotator‑cuff tear: Degenerative or traumatic tears become more likely with persistent bursitis.
• Calcific bursitis: Calcium deposits may accumulate, leading to severe pain and limited motion.
• Adhesive capsulitis (frozen shoulder): Prolonged inactivity can cause capsular tightening.
• Recurrent bursitis: Without addressing underlying mechanics, the condition often recurs.
