Shoulder Instability Traumatic anterior Traumatic posterior Acquired atraumatic Multidirectional Volontary

Traumatic anterior instability Incidence: 1,7% annually Recurrence rate: 90% <20 yrs Recurrence rate: 60% 20-40yrs Recurrence rate: <10% >40 yrs

Pathoanatomy Capsulolabral avulsion (Bankart) Capsular redundancy Bony defect (Hill Sachs/Glenoid)

Physical examination Generalized ligamentous laxity? Load and Shift test Apprehension Relocation Sulcus sign Posterior apprehension?

Imaging X ray (AP, scapular AP, axillary, West Point, Stryker notch) CT (bony defect) MRI (soft tissue,labrum, HAGL)

Surgical indications Failure of conservative treatment Patiënts < 25 yrs High demand sports Bony defect Rotator cuff tears

Treatment algorithm

Contra indications arthroscopic stabilization Engaging Hill-Sachs Bony defect > 20% anteroinferior glenoid Inverted pear

Engaging Hill-Sachs lesion

Open Bankart/Latarjet Young patients. Overhead, Collision sports Low recurrence rate Bony defect Engaging Hill-Sachs Inverted pear (>20% glenoid bone loss)

Arthroscopy: Set Up Beach chair Lateral decubitus

Arthroscopy Normal anatomy

Bankart repair

Bankart repair

Bankart repair

Surgical complications Recurrence Stiffness/Overtightening Subscapularis failure Anchor pull out Nervous injury (axillary nerve)

Postoperative clinical failures Failure to rule out concomitant cuff injury Failure to anatomically reconstruct anteroinferior labrum of IGHL Failure to recognize bony defects Inadequate capsular shift Inadequate retensioning IGHL

Rotator Cuff Tear Prevalence (full thicknes): 7-40% Increase with patient age Enlargement painfull cuff tears in time > 80 yr: up to 50%: asymptomatic Partial thickness: progression in size and symptoms

Anatomy Rotator Cuff

Anatomy Rotator Cuff

Rotator cuff

Pathoanatomy Intrinsic: changes collagen,proteoglycan, watercontent, vascularity Age dependant/degeneration Extrinsic: mechanical etiology/coracoacromial arch)

History <40 yrs: acute traumatic onset 50-60 yrs: traumatic/atraumatic >60 yrs: atraumatic

Classification Acute (< 3 months) Chronic (> 3 months) Acute on chronic (enlargement small tear) Full/Partial thickness Small, Medium, Large, Massive tears 1, 2 or 3 tendon involvement Partial (bursal, articular, < or> 50% thickness)

Physical Examination (1) Muscle atrophy Palpation (GT,AC,biceps,coracoid) Acive/Passive ROM Neer and Hawkins test Empty can and Jobe Lift-off test

Lift-off test

Physical examination (2) Resisted elevation test (supraspinatus) External rotation test (infraspinatus/teres m) External rotation lag sign (infraspinatus) Hornblower (teres minor) Lift-off/Abdominal compression (subscap) Deltoid integrity

Imaging X ray (true AP, acromiohumeral interval) X ray (external/internal rotation) Supraspinatus outlet (acromion morphology) Axillary view MRI (gold standard) Ultrasonography (accurate, operator dependant)

Imaging - Xray

Imaging - Ultrasound

Imaging: MRI MRI coronal T2 image MRI saggital oblique, retraction, atrophy, fatty infiltration

Imaging - MRI

Treatment (non surgical) Avoidance provocative moments Ice application NSAID s Physical therapy, deltoid strengthening Subacromial corticosteroid infiltration Elderly patients (degenerative tear)

Treatment (surgical) Failure of non-surgical treatment Acute traumatic tear (young patient) Acute loss of strength (any age) Good quality muscle No glenohumeral degeneration

Contra indication surgical repair Chronic infection Glenohumeral arthritis Retracted tendon Fatty infiltration Significant muscle atrophy Fixed proximal migration (AH interval < 7 mm) Deltoid/Axillary nerve dysfunction Bad prognostic factors (smoking, DM, high age, comorbidity

Literature J Shoulder Elbow Surg. 2015 Aug;24(8):1274-81. doi: 10.1016/j.jse.2015.05.040. Comparing surgical repair with conservative treatment for degenerative rotator cuff tears: a randomized controlled trial. Lambers Heerspink FO 1, van Raay JJ 2, Koorevaar RC 3, van Eerden PJ 4, Westerbeek RE 5, van 't Riet E 3, van den Akker-Scheek I 6, Diercks RL 6. CONCLUSION: In our population of patients with degenerative rotator cuff tears who were randomly treated by surgery or conservative protocol, we did not observe differences in functional outcome as measured with the CMS 1 year after treatment. However, significant differences in pain and disabilities were observed in favor of surgical treatment. The best outcomes in function and pain were seen in patients with an intact rotator cuff postoperatively.

Surgical repair Arthroscopic repair Mini-open repair (small and medium tears) Open repair (all sizes)

Rotator cuff repar constructs Single row repair (simple suture/mattress) Double row repair (medial and lateral based anchors) Transosseous equivalent

Complications Infection (Proprionibact acnes) Deltoid dehiscence Recurrent tear Iatrogenic injury suprascap nerve Stiffness (cave low grade infection) Missed other pathologic conditions (biceps, AC, instability, arthritis, cervical/neurological pathology)
