Shoulder Scope Indications

Shoulder Scope Contraindications

Shoulder Scope Alternatives

  • Open procedures
  • Non-operative treatment

Shoulder Scope Pre-op Planning / Special Considerations

  • Use 1:3000,0000 epinephrine irrigation fluid, electrocautery, hypotensive anesthesia(maintain SBP/subacromial BP difference of <50mm HG(Morrison DS, Arthroscopy 1995;11:557-60)
  • Procedure may be done in beach chair or lateral postions.
  • Beach Chair Position (BCP): intermittent SCD during surgery can increase cerebral oxygen saturation, cardiac output, stroke volume, ejection fraction, mean arterial pressure, and preload and decrease afterload.  BCP Complications: hypotension, venous air embolism, cerebral and spinal ischemia, death. (Kwak HJ, Arthroscopy. 2010 Jun;26(6):729-33(, (Bickel A, Am J Surg. 2011 Jul;202(1):16-22.)

Shoulder Scope Technique

  • Pre-operative antibiotics, +/- interscalene block
  • General endotracheal anesthesia
  • Modified beach-chair position. All bony prominences well padded.
  • Examination under anesthesia.
  • Prep and drape in standard sterile fashion
  • Bony landmarks marked out on the shoulder
  • Standard posterior portal just under posterior sulcus
  • Anterior portal lateral to coracoid process. 18-gauge spinal needle utilized for localization with placement just under the biceps tendon in the rotator interval.

Examination Under Anesthesia

  • Forward Elevation (R/L): 160 / 160
  • External Rotation at side (R/L): 50 / 50
  • External Rotation in 90 abduction (R/L): 85 / 85
  • Internal Rotation in 90 adbuction (R/L): 20 / 20
  • Load and shift
  • Sulcus sign

Viewing from Posterior Portal

  • Biceps tendon, Biceps labral complex
  • Biceps exit /
  • Posterior superior labrum, posterior capsular recess
  • Inferior axillary recess, anterior-inferior glenohumeral ligament
  • Inferior labrum
  • Glenoid articular surface
  • Supraspinatus tendon: evaluate with arthrosope in posterior portal and arm elevated 50 degrees and internally rotated. This fascilites lesser tuberosity visualization. (Bennett WF Arthroscopy 2001;10:37). Only the proximal 25% of the subscapularis tendon can be visualized intra-articularly. (Wright JM, Arthroscopy 2001;17:677)
  • Posterior rotator cuff / bare area
  • Humeral articular surface
  • superior, middle, inferior glenohumeral ligaments
  • Subcapularis tendon
  • Anterior inferior labrum, anterior inferior glenohumeral ligment
  • Evaluate Peel-back sign = entire superior BLC will shift medially as the arm is ER while in 70-90 degrees of abduction.  Generally found in posterior and combined anterior-posterior Type II SLAP lesions. (Burkhart SS, Arthroscopy 1998;14:637) (Burkhart SS, Arthroscopy 2003;19:404).
  • RTC tear Classification, BLC classification, SLAP classification,

Viewing from Anterior Portal

  • Posterior glenoid labrum
  • Posterior capsule
  • Posterior RTC (infraspinatus, terres
  • Anterior inferior labrum
  • Suscapularis tendon recess
  • Middle glenohumeral ligament
  • Subscapularis tendon, biceps tendon

Shoulder Scope Complications

  • Infections
  • Stiffness
  • CRPS
  • Nerve injury: Axillary nerve, Brachial plexus
  • Fluid Extravasation:
  • Chondrolysis: though to be related to heat from electo cautery or radiofrequency probes used during capsular release or capsular shrinkage.
  • Hematoma
  • Chondral Injury / arthritis
  • DVT/PE
  • Infections, Stiffness, CRPS, Nerve injury: Axillary nerve, Brachial plexus, Fluid Extravasation, Chondrolysis, Hematoma, Chondral Injury / arthritis, DVT/PE

Shoulder Scope Follow-up care

  • Post-op: sling as needed with pendulum ROM exercises.
  • See Shoulder Arthroscopy Rehab Protocol.
  • 1 week: Start PT focused on ROM and strengthening. AAROM, PROM.  AROM, free weights start at 3 weeks. Avoid cross-body adduction for 6 weeks if DCR performed.
  • 6 weeks: progressive sport specific activity.
  • 3 months: Return to sport / full activities.
  • IF in association with SAD, or RTC repair use those rehab protocols.
  • Outcome measures: ASES score, pain scales.
