The rotator cuff is why you can reach the top shelf, throw a ball, and sleep on your side. When it fails, all three go. At Remix Medical in Houston, our pain management physicians diagnose and treat rotator cuff pain with image-guided injection and coordinated rehabilitation.
What is Rotator Cuff Syndrome?
The rotator cuff is a group of four muscles and their tendons — supraspinatus, infraspinatus, teres minor, and subscapularis — that stabilize the head of the humerus within the shallow shoulder socket and drive its rotation.
Rotator cuff syndrome is an umbrella term covering tendinopathy, impingement, partial tearing, and full-thickness tearing of these tendons. The supraspinatus is most commonly involved, largely because it passes through a narrow space beneath the acromion where it is vulnerable to compression.
Common Causes of Rotator Cuff Syndrome
1. Impingement
The tendon is repeatedly compressed between the humeral head and the overlying acromion, particularly with overhead activity.
2. Degenerative Tendinopathy
Tendon quality declines with age. Blood supply to the supraspinatus is relatively poor at the very point where tears begin.
3. Repetitive Overhead Use
Painting, construction, swimming, racquet sports, and throwing.
4. Acute Trauma
A fall onto an outstretched hand or a sudden heavy lift can tear a tendon outright.
5. Acromial Shape and Bone Spurs
A hooked acromion narrows the space the tendon must pass through.
Symptoms of Rotator Cuff Syndrome
- Pain over the outer shoulder, often radiating toward the deltoid insertion
- Pain reaching overhead, behind the back, or across the body
- Night pain, particularly when lying on the affected shoulder — a hallmark symptom
- Weakness lifting the arm, or an inability to hold it elevated
- A painful arc of motion roughly between 60 and 120 degrees of elevation
- Catching or clicking with rotation
How Remix Medical Can Help
Examination distinguishes impingement from tearing, and both from adhesive capsulitis and cervical radiculopathy, which mimic them. Ultrasound and MRI clarify tendon integrity where the distinction changes management.
Our treatment options include:
- Subacromial and glenohumeral joint injections delivering corticosteroid under ultrasound guidance, which both reduces inflammation and helps confirm the pain source
- Suprascapular nerve block for refractory shoulder pain
- Platelet-rich plasma (PRP) for selected tendinopathy without full-thickness tear
- Medication management for pain and inflammation
- Physical therapy referral, which remains the foundation of treatment — scapular stabilization and cuff strengthening outperform injection alone over time
- Chiropractic and soft-tissue therapy through our in-house team
- Referral for orthopedic consultation when a full-thickness tear warrants surgical repair
| Approach | What it involves |
|---|---|
| Physical therapy | Rotator-cuff strengthening — effective for most partial tears and tendinopathy |
| Medications | Anti-inflammatories and topical agents for symptom control |
| Image-guided injections | Corticosteroid or PRP to reduce inflammation and enable therapy |
| Referral for surgery | Considered for full-thickness tears or persistent weakness |
