Critical Exam Concepts

Type II is KEY

Type II SLAP = biceps anchor detached. This is the clinically significant lesion. Types I and III can be debrided. Type IV involves biceps tendon itself.

Overhead Athletes

Throwers have posterosuperior SLAP tears from peel-back mechanism in late cocking. Often associated with GIRD (glenohumeral internal rotation deficit) and posterior capsular tightness.

SLAP Repair Declining

Recent literature shows high failure rates of SLAP repair, especially in patients over 40. Trend toward biceps tenotomy or tenodesis with comparable outcomes and faster recovery.

Age Matters

Under 40: Consider SLAP repair in motivated patient. Over 40: Biceps tenotomy or tenodesis preferred. Degenerative labral changes common over 40.

Overview and Epidemiology

Declining SLAP Repair Rates

SLAP repairs peaked then declined in the 2000s-2010s as studies showed high failure rates, especially in patients over 40 and throwers. Trend now toward biceps tenotomy or tenodesis which provides reliable pain relief with faster recovery.

Epidemiology

  • Originally described in 1990 (Snyder)
  • Peak age 26-50 years
  • Male greater than female
  • Overhead athletes overrepresented
  • Increasing diagnosis with MRI/arthroscopy

Mechanism

  • Compression: Fall on outstretched hand, arm forward and abducted
  • Traction: Sudden pulling force on arm
  • Peelback: Throwing motion (late cocking) in throwers
  • Degenerative: Age-related in Type I
  • Repetitive overhead: Cumulative microtrauma

Pathophysiology and Mechanisms

Superior Labral Anatomy

Location: 10 o-clock to 2 o-clock position on glenoid.

Biceps anchor: LHB tendon inserts at supraglenoid tubercle, blending with superior labrum.

Meniscoid appearance: Less firmly attached than anterior labrum - may appear loose on arthroscopy.

Blood supply: Relatively avascular zone (10-12 o-clock) - limits healing.

Long Head of Biceps Attachment

Supraglenoid tubercle: Main insertion point.

Labral contribution: Posterior LHB fibers blend with posterior superior labrum.

Function: Humeral head depressor (debated), some anterior stability function.

Peel-back mechanism: In ABER position, LHB becomes more vertical and peels the posterior labrum off glenoid.

Normal Variants

Sublabral foramen: Detachment of anterosuperior labrum at 1-3 o-clock. Normal variant - do not repair.

Buford complex: Cord-like MGHL with absent anterosuperior labrum. Normal variant.

Meniscoid labrum: Loose attachment superiorly - distinguished from SLAP by lack of instability/fraying.

Know these to avoid over-treating normal anatomy.

Distinguish SLAP from Normal Variants

Sublabral foramen (absent anterosuperior labrum) and Buford complex (cord-like MGHL) are normal variants that should NOT be repaired. True SLAP tears show: fraying, instability of biceps anchor, extension toward biceps, and positive peel-back test.

Classification Systems

Original Snyder Classification (Types I-IV)

TypePathologyTreatmentKey Point
IFraying of superior labrumDebridementAnchor intact - no repair
IIBiceps anchor detached from glenoidRepair or biceps procedureMOST IMPORTANT clinically
IIIBucket handle tear of labrumExcise bucket handleAnchor intact - preserve it
IVBucket handle extending into LHBExcise +/- repair/tenotomyBiceps tendon split

Type II Subdivisions

Type IIA (Anterior): Anterior extension of detachment.

Type IIB (Posterior): Posterior extension - seen in throwers (peel-back).

Type IIC (Combined): Both anterior and posterior extension.

Type IIB is characteristic of throwing athletes due to peel-back mechanism in late cocking phase.

Types V-X (Maffet et al.)

Type V: SLAP with anterior Bankart lesion.

Type VI: Flap tear of labrum with unstable anchor.

Type VII: SLAP extending into MGHL.

Types VIII-X are rarely used. Most important clinically are Types I-IV only.

Clinical Assessment

History

  • Mechanism: Compression, traction, throwing
  • Pain: Anterior/deep shoulder, with overhead activity
  • Clicking/popping: Common complaint
  • Sport level: Overhead athlete critical
  • Weakness: May report with overhead activity

Examination

  • O-Brien test: Pain with forward flex/adduct/IR, relieved with ER
  • Speed test: Resisted forward flexion
  • Anterior slide: Hand on hip, force applied
  • Biceps load test: ABER with biceps contraction
  • GIRD: Check internal rotation deficit

O-Brien Test (Active Compression Test)

Arm at 90° forward flexion, 10-15° adduction, thumb down (IR). Resist downward pressure. Then repeat with palm up (ER). Positive: Pain with IR, relieved with ER. Most commonly used clinical test for SLAP.

Key Examination Findings

Overhead athletes: Check for GIRD (internal rotation deficit greater than 20° compared to opposite side), posterior capsular tightness, scapular dyskinesis.

Combined pathology: SLAP tears often associated with rotator cuff pathology - assess thoroughly.

Investigations

MR Arthrography (Gold Standard)

Sensitivity: 82-98% for Type II SLAP.

Technique: Intra-articular gadolinium increases labral visualization.

Key findings: Contrast extension between labrum and glenoid at superior labrum.

ABER sequence: Increases sensitivity for peel-back lesions.

Superior to standard MRI for labral pathology.

Standard MRI

Less sensitive than MR arthrography for SLAP.

Useful for associated pathology: rotator cuff, other labral tears.

Superior labral pathology: Look for increased signal at labral-glenoid junction.

May miss subtle Type II lesions.

Diagnostic Arthroscopy

Definitive diagnosis of SLAP tears.

Peel-back test: Place arm in ABER position. Watch for posterosuperior labral lift-off.

Probe: Test stability of biceps anchor.

Allows simultaneous treatment.

Distinguish from normal variants (sublabral foramen, Buford).

Peel-Back Test

Arthroscopic ABER positioning: With arm in abduction and external rotation (throwing position), the biceps vector becomes vertical and peels the posterosuperior labrum off the glenoid. Positive peel-back = Type II SLAP (especially IIB in throwers).

SLAP Type-Based Treatment

Decision Pathway

Type IDebridement

Degenerative fraying. Anchor intact. Simple debridement of frayed tissue. No repair needed.

Type IIRepair or Biceps Procedure

Biceps anchor detached. Options: SLAP repair (under 40, motivated), biceps tenotomy (over 40, low demand), or tenodesis (over 40, active).

Type IIIExcision

Bucket handle tear. Anchor intact. Excise the displaced bucket handle fragment. Preserve the anchor.

Type IVExcise and Decision

Bucket handle into biceps. If less than 30% biceps involvement: excise bucket handle. If greater than 30%: biceps tenotomy or tenodesis.

Type II SLAP Decision Tree

Factors favoring SLAP repair:

  • Age under 40
  • High-demand athlete wanting to preserve biceps
  • Isolated Type II without other pathology
  • Motivated for prolonged rehabilitation
  • Non-thrower

Factors favoring biceps procedure:

  • Age over 40
  • Concomitant biceps tendon pathology
  • Failed conservative treatment
  • Failed previous SLAP repair
  • Throwing athlete (high failure rate with repair)
  • Low demand patient

Consider patient preferences and activity goals when selecting procedure.

Non-Operative Management

Indications: Mild symptoms, low-demand patient, willing to modify activities.

Protocol:

  • Rest from aggravating activities
  • NSAIDs for pain control
  • Physical therapy: rotator cuff and scapular strengthening
  • Address GIRD if present (stretching)
  • Gradual return to overhead activities

Success rate: Variable. Many progress to surgery if high demand.

Surgical Technique

Arthroscopic SLAP Repair

Surgical Steps

Step 1Diagnostic Arthroscopy

Confirm SLAP classification. Perform peel-back test. Assess biceps tendon quality.

Step 2Preparation

Debride frayed tissue. Decorticate glenoid rim to bleeding bone. Mobilize the labrum.

Step 3Anchor Placement

1-3 suture anchors at superior glenoid rim. Place at 10-11 o-clock and 12-1 o-clock. Avoid suprascapular nerve on superior anchor.

Step 4Labral Repair

Pass sutures through labrum. Tie to restore labral bumper and biceps anchor stability.

Anchor Positioning

Avoid placing anchors too posterior (risk suprascapular nerve at spinoglenoid notch) or too medial on glenoid neck (inadequate purchase). Anchors should be on the glenoid rim at the articular margin.

Arthroscopic Biceps Tenotomy

Indication: Age over 40, low demand, degenerative biceps.

Technique: Simply cut the LHB at its origin. Tendon retracts into groove and scars.

Advantages: Simple, fast recovery, reliable pain relief.

Disadvantages: Popeye deformity (30-70%), potential cramping, cosmetic concern.

Outcome: Excellent pain relief. Minimal functional deficit for most patients.

Biceps Tenodesis

Indication: Age over 40, cosmetically concerned, active patient.

Technique: Release LHB, fix distally in groove with interference screw or anchor.

Location: Suprapectoral (arthroscopic) or subpectoral (open).

Advantages: Avoids Popeye deformity, maintains biceps length-tension.

Subpectoral preferred: Removes all biceps from groove, reduces persistent pain.

SLAP Repair Failure in Throwers

Overhead throwing athletes have 33-64% failure rate after SLAP repair in some studies. The peel-back forces during throwing stress the repair. Many surgeons now recommend biceps tenotomy/tenodesis for throwers with Type II SLAP.

Postoperative Care

Rehabilitation Protocol (SLAP Repair)

Week 0-4Protection Phase

Sling immobilization. Elbow/hand exercises. Gentle pendulums only. No active biceps.

Week 4-8Early Motion

Wean sling. Passive to active-assisted ROM. Avoid ABER position. No resisted biceps.

Week 8-12Active ROM

Full AROM. Isometric cuff strengthening. Begin light biceps activity.

Month 3-6Strengthening

Progressive resistance. Sport-specific training. No throwing until 6 months minimum.

Tenotomy/Tenodesis Recovery

Biceps procedures have faster recovery. Tenotomy: sling 1-2 weeks, no restrictions by 6 weeks. Tenodesis: protect biceps 6 weeks, no heavy biceps loading 3 months. Both return to full activity faster than SLAP repair.

Outcomes and Prognosis

Procedure-Specific Outcomes

SLAP Repair: 60-80% good outcomes overall. Higher failure rate in throwers (33-64%), patients over 40, and workers compensation. Stiffness is common concern.

Biceps Tenotomy: 85-95% pain relief. Popeye deformity in 30-70%. Minimal strength loss for daily activities.

Biceps Tenodesis: Similar pain relief to tenotomy. Lower cosmetic deformity rate. Preferred in younger/active/cosmetically concerned patients.

Return to Sport

SLAP repair: 6-9 months for non-throwing sports. Throwing athletes may take 9-12 months with variable return to prior level.

Biceps procedures: Often faster return (3-4 months).

Evidence Base and Key Studies

Exam Viva Scenarios

Practice these scenarios to excel in your viva examination

VIVA SCENARIOStandard

Scenario 1: Young Athlete with Shoulder Pain

EXAMINER

"A 28-year-old recreational volleyball player presents with right shoulder pain during overhead serving. O-Brien test is positive. MR arthrography shows a Type II SLAP lesion with intact biceps tendon. How would you manage this?"

EXCEPTIONAL ANSWER
This is a Type II SLAP tear - the clinically significant SLAP lesion where the biceps anchor is detached from the glenoid. My initial management would include confirming the examination findings and ensuring no other pathology is present. Given her age (under 40), recreational (not elite) sport level, and intact biceps tendon, I would discuss treatment options. Conservative management could be attempted first: relative rest, NSAIDs, and physical therapy focusing on rotator cuff strengthening and addressing any posterior capsular tightness. If conservative treatment fails after 3-6 months, I would recommend arthroscopic SLAP repair. At surgery, I would confirm the diagnosis with peel-back test, prepare the glenoid rim, and place 1-2 suture anchors to repair the detached labrum and biceps anchor. Postoperatively, she would be in a sling for 4 weeks, followed by progressive ROM and strengthening. Return to volleyball would be at 6-9 months. I would counsel her that SLAP repair has variable outcomes (60-80% success) and if her primary goal is pain relief, biceps tenodesis is an alternative with potentially faster recovery.
KEY POINTS TO SCORE
Type II SLAP = biceps anchor detached
Trial conservative treatment first
SLAP repair reasonable in under 40, motivated patient
Counsel on variable outcomes
Biceps procedure is alternative option
COMMON TRAPS
✗Jumping to surgery without conservative trial
✗Not distinguishing Type II from other SLAP types
✗Over-promising SLAP repair outcomes
✗Not assessing for associated pathology
LIKELY FOLLOW-UPS
"What if she were 45 years old?"
"What is the peel-back test?"
"What are normal anatomical variants at superior labrum?"
VIVA SCENARIOChallenging

Scenario 2: Failed SLAP Repair

EXAMINER

"A 35-year-old had SLAP repair 18 months ago but has persistent anterior shoulder pain with overhead activities. MRI shows the repair appears intact. What is your approach?"

EXCEPTIONAL ANSWER
This is persistent pain after SLAP repair, which occurs in 20-40% of cases. My approach would be systematic. First, I would re-evaluate the diagnosis - are there other pain generators? I would examine for rotator cuff pathology, acromioclavicular joint pathology, and cervical spine referral. I would review the MRI for subtle cuff tears or biceps tendinopathy within the groove. I would also ask about the character of pain and whether it matches preoperative symptoms. Assuming the SLAP repair is intact and there is no other identifiable pathology, the persistent pain may be due to: 1) Stiffness/capsular tightness from the repair, 2) Subclinical repair failure not visible on MRI, or 3) The labral pathology was not the primary pain source. If physical therapy has been exhausted, I would consider diagnostic arthroscopy. At arthroscopy, I would assess the repair (may show subtle failure), probe for instability, and examine the biceps in its groove. If the repair is intact but the biceps tendon shows tendinopathy, I would recommend biceps tenodesis. Cutting out the biceps from the repair and fixing it distally often provides reliable pain relief. This salvage procedure has good outcomes for failed SLAP repairs.
KEY POINTS TO SCORE
20-40% failure rate after SLAP repair
Rule out other pain generators
Biceps tenodesis is effective salvage procedure
MRI may not show subtle repair failure
Consider diagnostic arthroscopy if unclear
COMMON TRAPS
✗Assuming repair failure without evaluation
✗Missing concurrent pathology (cuff, AC joint)
✗Repeating SLAP repair (high failure rate)
✗Not considering biceps contribution to pain
LIKELY FOLLOW-UPS
"What is the advantage of subpectoral tenodesis?"
"What if the biceps tendon is completely degenerative?"
"What outcomes can you quote for biceps tenodesis?"
VIVA SCENARIOCritical

Scenario 3: Throwing Athlete

EXAMINER

"A 22-year-old elite baseball pitcher has posterior shoulder pain during the cocking phase of throwing. MR arthrography shows a posterosuperior Type IIB SLAP tear. Examination also reveals 25° GIRD. What is your treatment plan?"

EXCEPTIONAL ANSWER
This is a classic throwing athlete presentation - posterior Type IIB SLAP from peel-back mechanism during late cocking, with associated GIRD (glenohumeral internal rotation deficit) indicating posterior capsular contracture. This is one of the most challenging shoulder problems to treat. My approach would begin with aggressive non-operative management. The GIRD must be addressed first with sleeper stretches and cross-body stretching to restore internal rotation. Physical therapy would focus on posterior capsular flexibility, rotator cuff strengthening, and scapular stabilization. I would counsel him that SLAP repairs in throwers have high failure rates (33-64% in some studies) and many pitchers do not return to their preinjury level. If conservative treatment fails after 3-6 months, surgical options include: 1) SLAP repair - but with guarded prognosis given the peel-back forces in throwing; 2) SLAP repair with posterior capsular release - to address the GIRD component; or 3) Biceps tenodesis - increasingly favored given poor SLAP repair outcomes in throwers. I would have an honest discussion with him about the possibility that he may not return to elite-level pitching regardless of treatment choice. Some surgeons now prefer early biceps tenodesis in throwing athletes with SLAP tears.
KEY POINTS TO SCORE
Type IIB SLAP = posterior, from peel-back in throwers
GIRD indicates posterior capsular tightness
Address GIRD with stretching before/with surgery
High failure rate of SLAP repair in throwers
Biceps tenodesis increasingly favored
COMMON TRAPS
✗Recommending SLAP repair without counseling on poor outcomes
✗Not addressing GIRD
✗Overpromising return to elite performance
✗Rushing to surgery without conservative trial
LIKELY FOLLOW-UPS
"What is the peel-back mechanism?"
"How would you address GIRD surgically?"
"What is your preferred biceps procedure and why?"

MCQ Practice Points

Type II SLAP

Q: Which SLAP type is the most clinically significant? A: Type II - biceps anchor is detached from the glenoid. This requires surgical treatment (repair or biceps procedure). Types I and III can usually be debrided.

Type I Treatment

Q: How is a Type I SLAP treated? A: Debridement only. Type I is degenerative fraying with intact biceps anchor. No repair is needed - simply debride the frayed tissue.

Peel-Back Test

Q: What does a positive peel-back test indicate? A: Type II SLAP tear (especially Type IIB). In ABER position, the biceps vector becomes vertical and peels the posterosuperior labrum off the glenoid.

O-Brien Test

Q: How is the O-Brien test performed? A: Arm at 90° forward flexion, 10-15° adduction, thumb down (IR). Resist downward pressure. Repeat with palm up (ER). Positive: pain with IR, relieved with ER.

Sublabral Foramen

Q: What is the sublabral foramen? A: Normal anatomical variant - detachment of anterosuperior labrum at 1-3 o-clock position. Should NOT be repaired. Distinguished from SLAP by stable biceps anchor.

Age and SLAP Repair

Q: Why is SLAP repair less recommended in patients over 40? A: 50% failure rate in patients over 40. Degenerative labral/biceps changes reduce healing. Biceps tenotomy or tenodesis preferred for reliable pain relief.
