  1. When to repair the rotator cuff? Mr Simon Holland Ringwood Private Hospital www.simonholland.com.au

  2. Take home messages • The rotator cuff has limited healing potential • Untreated rotator cuff tears may result in cuff tear arthropathy • Consider in all patients less than 60 y.o. • Need a mobile shoulder

  3. The rotator cuff has limited healing potential • The tendon typically tears in a hypovascular zone of the supraspinatus tendon • Poor blood supply = poor healing potential • Once a full thickness tear, the tendon retracts across the humeral head with minimal chance to adhere to this surface

  4. Untreated rotator cuff tears may result in cuff tear arthropathy • This can be painful or painless • Often in patients with previous surgery • Difficult treatment options dependent on bone anatomy and pain • Treatment aims to maximize function vs loss of pain

  5. Consider in all patients less than 60 y.o. • 60% of 60 year olds will have a rotator cuff tear on imaging • Most will will be asymptomatic • Most 70 year old rotator cuff tissue is of questionable quality

  6. Need a mobile shoulder • A rotator cuff repair in a frozen shoulder is unlikely to be successful • Aim for passive range of motion • Physio - Jackin’s program • Hydrodilatation • Time • Surgical release

  7. Case 1 • F53 Hairdresser self employed • Night pain, struggling with work (shoulder height) for 12 months • Failed physio • Good ROM • Weak SS (4/5) • Acromioclavicular joint non tender

  8. Rotator Cuff Examination • Tenderness - tendon insertion, AC joint • If AC joint, ? cross arm or O’Brien’s aggravates • If posterior joint line, ? degenerative joint • ROM - exclude adhesive picture • Power (out of 5) • SS, IS, Subsc, Biceps

  9. Imaging • Ultrasound (not particularly useful) • Suggested no tear, and patient delayed in presentation • Xrays - arranged - every patient • AP, true AP, Scapular Lateral and Axillary Lateral • Exclude other causes - OA, AC joint, fracture, cancer

  10. Glenohumeral Arthritis

  11. True AP

  12. AP

  13. Scapula Lateral

  14. Axillary Lateral

  15. Imaging MRI scans • When diagnosis is in doubt such as when pain is severe and patient wishes to know now, and not wait for time • Suspect multiple pathologies / limited equipment inventory • When third parties have an interest. Check and acknowledge other pain generators

  16. Management Diagnosis • SS full thickness tendon tear Treatment Options • More of the same with subacromial cortisone injections • Surgical

  17. Treatment Non Operative • Much research into why most tears are asymptomatic • EMG studies suggest poor subscap function in painful tears, but subscap directed treatment has not produced clinical nor EMG results • Equatorial theories - tear extends beyond a certain latitude, defunctioning the intact tendons

  18. Treatment Operative Options • Subacromial Decompression • Rotator Cuff Repair • Acromioclavicular joint excision • Biceps Tenodesis

  19. Subacromial Decompression • Arthroscopic or open • Assess coracoacromial ligament and undersurface of acromion • Smooth and débride • Resect subacromial bursa • Débride partial thickness tears of the undersurface(articular sided) of the rotator cuff

  20. Rotator Cuff Repair • Arthroscopic, Open or Combination • Complete and incomplete • Anchors vs no anchors • Single vs double row repairs

  21. Acromioclavicular Joint Excision • Often co-existing pathology • May contribute to SS impingement • Open or Arthroscopic

  22. Biceps Tenodesis • Biceps often involved, especially with subscap tears where it subluxates and impinges against the coracoid process with adduction and internal rotation • Reattach or tenotomize • Can be trouble in its own rite

  23. Principle Risks • Unintentional stiffness - compared to stabilization • Infection - < 1% for arthroscopic procedures • Repair failure, often asymptomatic • Healing of collagen is weakest at 4 months

  24. Procedure • Overnight • Home exercise program • Analgesia and ice • Oxycontin, oxycodone/p. forte/digesic, NSAID • Sling for 6 weeks

  25. Recovery • 0 - 10 days - standard exercises, keep away from work • 11d to 6 weeks - sling, light duties • 6 - 12 weeks - no sling, light duties • > 12 weeks - start to see a physio • > 6 months - aim for normal duties • 18 month before full recovery

  26. Recovery • 0 - 2 weeks - will not think I am a friend • 6 weeks - suspect I have helped • 3 months - certain that I have helped and frustrated at the speed of healing • 6 months - about 90% when look back

  27. Case 1 • Uneventful double row arthroscopic supraspinatus repair

  28. Case 2 • M45, truck driver • Fall 2 months ago while unloading truck • Sudden pain, unable to lift away from body and not responding to non op measures • Smoker

  29. Case 2 • Slight loss ROM • Tender - B, SS, Subsc • SS 4+. Subsc 3 (belly press), B 4 • Prominent AC, non tender

  30. Case 2 US - aPTT of SS (hoped for a clue with biceps - need good ROM) XR and MRI • SS and Subsc FTT with Biceps Subluxation • AC arthropathy

  31. Case 2 • 3 cm subsc tear, < 1 cm SS tear • Arthroscopic Subacromial decompression • Arthroscopic AC Joint excision • Open Subscap and SS repair with biceps tenodesis

  32. Case 2

  33. Case 3 • F47 Office work • Fall in garden 8 months ago • Initially not able to actively move, sling for two weeks, gradual loss of movement • CSI of no value • NIDDM

  34. Case 3 • Poor ROM and global cuff weakness 4/5 • Tender - general, AC  • US - SS tear • XR - no OA

  35. Case 3 • MRI - not going to change management. • Treat as adhesive capsulitis and when motion restored, reassess rotator cuff clinically and radiologically as indicated.

  36. Case 4 • M35, sales representative • Mountain bike accident on single trail • ? dislocation, self reduced 6 weeks ago • Unable to elevate arm

  37. Case 4 • Tender SS, posterior humeral head, anterior joint line • Full passive ROM, reduced active (< 60 FE) • Anterior laxity and positive apprehension signs • 3/5 SS power

  38. Case 4 General Rule • 50% of those > 40 y.o. with a first time traumatic dislocation will have a rotator cuff tear. • Treatment is directed at the rotator cuff first and the instability second. • MRI is often helpful

  39. Case 4

  40. Case 5 • M63, farmer • Longstanding ache that was at nuisance level for years, tripped at home and worsening pain and function • SS 4/5, IS 3/5

  41. Case 5 Diagnosis = Massive Rotator Cuff tear • Xray to exclude fracture • Likely longstanding tear that extended. • Arthroscopic techniques offer less morbidity and better access to tendons • Discuss possible irreparable tendon

  42. Case 5 • > 5 cm tear (massive) • Double row repair

  43. Questions ?

  44. Summary • When symptoms are more than a nuisance and non operative measures have been explored, surgical management and possible repair are viable treatment options.
