Introduction Superior Labrum from Anterior to Posterior tears May occur as isolated lesion or be associated with internal impingement rotator cuff tears (usually articular sided) instability (may be subtle) Mechanisms repetitive overhead activities (often seen in throwing athletes) fall on outstretched arm with tensed biceps traction on the arm Pathophysiology in throwers may be due to tightness of the postero-IGHL which shifts the glenohumeral contact point posterosuperiorly and increases the shear force on the superior labrum SLAP lesion increases the strain on the anterior band of the IGHL and thus compromises stability of shoulder Anatomy Anatomy of glenohumeral joint Biceps tendon attachment on glenoid (Tuoheti classification) Type I - completely posterior Type II - predominantly posterior Type I and II together comprise >70% Type III - anterior + posterior (25%) Type IV - anterior (5%) Glenoid labrum function chock block to subluxation composition composed of fibrocartilagenous tissue blood supply from suprascapular, circumflex scapular, posterior humeral circumflex arteries labrum receives blood from capsule and periosteal vessels and not from underlying bone anterior-superior labrum has poorest blood supply stability superior labrum anchors biceps tendon (weak link that leads to SLAP lesion) most common pattern of biceps tendon attachment to the superior labrum is posterior to the 12 o'clock position anatomic variants sublabral recess can be confused with a tear on MRI meniscoid appearance (1%) Buford complex cordlike MGHL with associated bare area of the anteriosuperior labrum Classification SLAP Classification Type Description % Images I Labral and biceps fraying, anchor intact 11% II Labral fraying with detached biceps tendon anchor 41% III Bucket handle tear, intact biceps tendon anchor (biceps separates from bucket handle tear) 33% IV Bucket handle tear with detached biceps tendon anchor (remains attached to bucket handle tear) 15% V Type II + anterointerior labral extension (Bankart lesion) m m VI Type II + unstable flap m m VII Type II + MGHL injury m m VIII Type II + posterior extension IX Circumferential X Type II + posteroinferior extension (reverse Bankart) Snyder Classification: Original classification which includes Types I-IV Maffet sub-classification: Includes the original I-IV and adds Types V-VII Presentation Symptoms vague deep shoulder pain (there is often a lag between the time of injury and the onset of symptoms) mechanical symptoms of popping and clicking weakness, easy fatigue, and decrease athletic performance Physical exam provocative tests active compression test (O'Brien's test) Crank test Dynamic labral shear test biceps tendon tenderness patients commonly have GIRD apprehension positive in 85% of patients physical findings of suprascapular neuropathy secondary to a spinoglenoid cyst Imaging Radiographs should be normal MRI T2 linear signal intensity between the superior labrum and the glenoid rim sensitivity ~50% and specificity ~90% which increases with arthrogram may see an associated paralabral ganglion cyst usually in the spinoglenoid notch may result in denervation changes to infraspinatus Arthroscopy diagnosis can only be confirmed with arthroscopy look for erythema and tearing under labrum to differentiate from normal recess "peel back" test shows "peel back" of the labrum with 90° of external rotation and abduction Treatment Nonoperative physical therapy, NSAIDs indications first line of treatment address GIRD, scapular dyskinesia, rotator cuff incidental SLAP finding in older patients (>45 years) having arthroscopic rotator cuff repair, it is not necessary to repair a SLAP lesion that is found incidentally. It may actually lead to stiffness if it is repaired. Operative arthroscopic debridement and stabilization of the labrum and biceps tendon indications severe symptoms that have failed nonoperative management complications overdrilling the glenoid can injury the suprascapular nerve Techniques Arthroscopic debridement and stabilization of the labrum and biceps tendon approach standard arthroscopic approach to the shoulder technique Type I - debride labrum Type II - reattach labrum Type III - debridement of flaps Type IV if tendon involvement < 1/3, then excise the bucket if tendon involvement >1/3, same and perform biceps tenodesis or tenotomy. decompress any cysts rehabilitation week 1-4 sling with passive forward elevation. Avoid extremes of abduction and external rotation passive and active assisted flexion in the scapular plane week 4-6 progress to active ROM, isometrics week 6-12 functional exercise and light strengthening week 12+ advance strength and ROM, sport-specifics typical return to sport around 6 months
