Rotator Cuff Tear — বাংলা ক্লিনিক্যাল নোট
1) Definition / সংজ্ঞা
Rotator cuff tear হলো shoulder joint-এর ৪টি tendon—Supraspinatus, Infraspinatus, Teres minor, Subscapularis—এর আংশিক বা সম্পূর্ণ ছিঁড়ে যাওয়া। Tear হতে পারে:
- Partial-thickness tear: tendon পুরোপুরি ছিঁড়ে যায় না।
- Full-thickness tear: tendon এক পাশ থেকে আরেক পাশ পর্যন্ত ছিঁড়ে যায়।
- Massive tear: সাধারণত ≥২টি tendon জড়িত বা বড় retraction থাকে।
এটি বয়স্ক ও overhead activity করা ব্যক্তিদের shoulder pain-এর সাধারণ কারণ; tear traumatic বা degenerative—দুইভাবেই হতে পারে।
2) Causes / Etiology & Pathophysiology — কারণগুলো
A. Degenerative / বয়সজনিত ক্ষয়জনিত কারণ
- বয়স বাড়ার সঙ্গে tendon-এর collagen দুর্বল হয়।
- supraspinatus tendon-এর “critical zone” এলাকায় blood supply কম থাকায় healing capacity কম।
- ছোট ছোট micro-tear জমে বড় tear হয়।
- ৫০ বছরের বেশি বয়সে ঝুঁকি বেশি।
B. Repetitive overhead activity
- বারবার হাত মাথার ওপরে তোলা: painter, construction worker, electrician, athlete, swimmer, badminton/tennis player।
- repetitive impingement tendon-এ friction তৈরি করে।
- দীর্ঘমেয়াদে tendinopathy → partial tear → full tear হতে পারে।
C. Trauma / আঘাত
- পড়ে গিয়ে হাত দিয়ে ভর দেওয়া।
- shoulder dislocation-এর পর।
- হঠাৎ ভারী জিনিস তুলতে গিয়ে।
- young patient-দের tear বেশি traumatic হয়।
D. Subacromial impingement
- acromial spur বা hooked acromion tendon-এর ওপর চাপ দেয়।
- subacromial bursitis থাকলে tendon আরও irritated হয়।
E. Risk factors
- Diabetes mellitus
- Smoking
- Obesity
- Hyperlipidaemia
- Poor posture / scapular dyskinesia
- Previous shoulder injury
- Heavy manual labour
- Overhead sports
Age >50, diabetes এবং overhead activity rotator cuff tendinopathy/tear-এর গুরুত্বপূর্ণ risk factor হিসেবে পাওয়া যায়।
3) Symptoms / Clinical Features — লক্ষণগুলো
- Shoulder pain: সাধারণত shoulder-এর বাইরের দিক বা lateral deltoid area-তে ব্যথা।
- Night pain: affected side-এ শুতে গেলে ব্যথা বাড়ে।
- Overhead activity pain: চুল আঁচড়ানো, জামা পরা, মাথার ওপর কিছু রাখা কষ্টকর।
- Weakness: হাত পাশ দিয়ে তুলতে বা বাইরে ঘুরাতে দুর্বলতা।
- Painful arc: হাত ৬০°–১২০° পর্যন্ত তুললে ব্যথা বেশি।
- Difficulty in abduction: supraspinatus tear হলে arm abduction দুর্বল হয়।
- External rotation weakness: infraspinatus/teres minor tear হলে হাত বাইরে ঘুরানো দুর্বল হয়।
- Internal rotation weakness: subscapularis tear হলে পিঠের পেছনে হাত নেওয়া কষ্টকর।
- Clicking/crepitus: shoulder নড়ালে শব্দ বা ঘর্ষণ অনুভব হতে পারে।
- Acute traumatic tear: sudden sharp pain, “pop” sensation, হাত তুলতে না পারা।
- Massive tear: pseudoparalysis—passive movement আছে, কিন্তু active movement খুব কম।
4) Clinical Diagnosis — bedside diagnosis কীভাবে করবেন
Rotator cuff tear diagnosis হয় history + examination + imaging দিয়ে। কোনো একক clinical test ১০০% নিশ্চিত নয়; test combination diagnostic accuracy বাড়ায়।
A. Inspection
- supraspinatus/infraspinatus fossa wasting আছে কি না।
- scapular winging বা dyskinesia আছে কি না।
- shoulder asymmetry।
B. Range of motion
- Active ROM কম, passive ROM relatively preserved → rotator cuff tear suggestive।
- Active ও passive দুটোই কম → adhesive capsulitis ভাবতে হবে।
C. Specific clinical tests
Supraspinatus
- Jobe’s test / Empty can test: pain বা weakness হলে positive।
- Full can test: supraspinatus assessment।
- Drop arm test: হাত ধীরে নামাতে না পারলে full-thickness tear suggestive; specificity বেশি।
Infraspinatus / Teres minor
- Resisted external rotation test
- External rotation lag sign
- Hornblower’s sign / Drop sign: teres minor involvement suggestive।
Subscapularis
- Lift-off test
- Belly-press test
- Bear-hug test
Impingement-associated tests
- Neer impingement test
- Hawkins–Kennedy test
- Painful arc test: ৬০°–১২০° pain suggestive।
Empty can test sensitivity বেশি, আর drop arm ও lift-off test specificity বেশি—তাই rule-in করতে helpful।
5) Investigations — specific work-up
1. X-ray shoulder — initial test
Views:
- AP view
- Axillary view
- Scapular Y view
Purpose:
- fracture/dislocation exclude করা
- acromial spur দেখা
- glenohumeral arthritis দেখা
- chronic massive tear হলে superior migration of humeral head দেখা
2. Ultrasonography
Use:
- partial/full-thickness tear detect
- dynamic impingement দেখা
- cost-effective
- experienced operator দরকার
3. MRI shoulder — best for detailed evaluation
MRI tells:
- tear size
- full vs partial thickness
- tendon retraction
- muscle atrophy
- fatty infiltration
- biceps/labrum/bursa pathology
- surgical planning
AAOS guideline অনুযায়ী MRI, MRA, CT এবং ultrasound—clinical exam ও radiograph-এর adjunct হিসেবে rotator cuff tear শনাক্ত করতে useful।
4. MR arthrogram
Best when:
- partial articular-sided tear সন্দেহ
- labral lesion associated
- young athlete
5. CT arthrogram
Indication:
- MRI contraindicated, যেমন pacemaker/metallic implant compatibility issue।
6. Lab tests
Routine দরকার নেই। তবে differential diagnosis থাকলে:
- CBC, ESR, CRP — infection/inflammatory arthritis সন্দেহে
- HbA1c — diabetes control, steroid injection/surgery planning
- Uric acid — gouty shoulder bursitis rare suspicion
6) Differential Diagnosis
- Adhesive capsulitis
- Subacromial bursitis
- Calcific tendinitis
- Biceps tendinopathy
- AC joint arthritis
- Glenohumeral osteoarthritis
- Cervical radiculopathy
- Shoulder instability
- Labral tear
- Fracture/dislocation
- Polymyalgia rheumatica
- Inflammatory arthritis
7) Complications — রোগের জটিলতা
- Tear progression: partial tear থেকে full-thickness tear হতে পারে।
- Chronic pain: দীর্ঘদিন ব্যথা থেকে sleep disturbance ও mood problem হতে পারে।
- Weakness and functional disability: জামা পরা, মাথা আঁচড়ানো, কাজ করা কঠিন হয়।
- Frozen shoulder / stiffness: pain এড়িয়ে নাড়াচাড়া কমালে shoulder stiff হয়ে যায়।
- Tendon retraction: tendon পেছনে সরে গেলে repair কঠিন হয়।
- Muscle atrophy ও fatty degeneration: delayed treatment-এ muscle quality খারাপ হয়।
- Cuff tear arthropathy: chronic massive tear-এ humeral head superior migrate করে arthritis হতে পারে।
- Pseudoparalysis: massive tear-এ patient হাত তুলতে পারে না।
- Failed conservative treatment: দীর্ঘদিন physiotherapy/medicine কাজ না করলে surgery লাগতে পারে।
AAOS guideline summary অনুযায়ী physiotherapy symptomatic full-thickness tear-এ improvement দিতে পারে, কিন্তু দীর্ঘমেয়াদে tear size, muscle atrophy ও fatty infiltration progress করতে পারে।
8) Treatment & Management

10) Bangladesh doctors commonly used prescription pattern
Mild pain / early degenerative tear
- Paracetamol
- Topical diclofenac gel
- Physiotherapy
কারণ: pain control + safer profile + rehab শুরু করা।
Moderate inflammatory pain
- One NSAID: ibuprofen OR naproxen OR diclofenac OR etoricoxib
- PPI if gastric risk
- Physiotherapy
কারণ: inflammation ও pain কমিয়ে shoulder movement restore করা।
Severe night pain
- Paracetamol + short-course tramadol combination
কারণ: rescue analgesia; long-term ব্যবহার করা উচিত নয়।
Muscle spasm থাকলে
- Tolperisone or tizanidine short course
কারণ: secondary muscle guarding কমানো; tear heal করে না।
Persistent pain despite oral medicine
- Single subacromial triamcinolone + lidocaine injection
কারণ: short-term pain relief দিয়ে physiotherapy enable করা।
Avoid
- long-term NSAID without monitoring
- two NSAID together
- repeated steroid injection
- antibiotic without infection
- routine “nerve vitamin” unless deficiency/neuropathy indication
11) Prevention — কীভাবে প্রতিরোধ করবেন
- overhead কাজের আগে warm-up করবেন।
- rotator cuff ও scapular stabilizer strengthening করবেন।
- sudden heavy lifting avoid করবেন।
- repetitive overhead work করলে break নেবেন।
- proper lifting technique শিখবেন।
- sports technique correction করবেন।
- diabetes control করবেন।
- smoking বন্ধ করবেন।
- posture correction করবেন।
- shoulder pain হলে early physiotherapy শুরু করবেন।
- affected side-এ দীর্ঘক্ষণ শোয়া avoid করবেন।
- fall prevention, especially elderly patient-এ।
Overview / Summary
Rotator cuff tear shoulder pain ও weakness-এর সাধারণ কারণ। Diagnosis হয় history, specific clinical tests এবং imaging দিয়ে। X-ray initial, ultrasound practical, MRI surgical planning-এর জন্য best. Management-এর মূল হলো activity modification + structured physiotherapy. Medicine pain control-এর জন্য; tendon repair করে না। Acute traumatic full-thickness tear, pseudoparalysis বা major weakness থাকলে early orthopedic referral দরকার।
Actionable Plan / Steps
- History নিন: trauma, overhead work, night pain, weakness, duration।
- Examination করুন: active/passive ROM, painful arc, empty can, drop arm, ER lag, lift-off/belly-press।
- Initial investigation: shoulder X-ray; tear suspicion থাকলে USG বা MRI।
- Conservative trial: partial/small degenerative tear হলে ৬–১২ সপ্তাহ physiotherapy + safe analgesia।
- Medicine: paracetamol first; need হলে one NSAID only; GI risk থাকলে PPI।
- Injection: severe pain preventing rehab হলে single subacromial steroid injection।
- Refer urgently: acute traumatic inability to lift arm, pseudoparalysis, young active patient full-thickness tear, neurovascular deficit, suspected fracture/dislocation।
