What are the treatment options for a symptomatic Buford complex in a 20-year-old patient?

Treatment of Symptomatic Buford Complex in a 20-Year-Old

For a symptomatic Buford complex in a 20-year-old, the treatment approach depends critically on the specific pathology present: if asymptomatic or an incidental finding, no intervention is needed; if associated with shoulder instability, arthroscopic stabilization using the cord-like MGHL to reconstruct a neo-labrum is the preferred technique; if associated with a SLAP tear, repair the SLAP lesion while transecting the MGHL at the glenoid equator and incorporating the proximal segment into the repair.

Understanding the Buford Complex

The Buford complex is an anatomical variant (not a pathology) consisting of:

• A cord-like middle glenohumeral ligament (MGHL)
• Absence of the anterosuperior labrum
• Occurs in 1.5-6.5% of the population 1

Critical pitfall: The Buford complex itself is NOT pathologic and should never be "repaired" if asymptomatic. Mistakenly repairing it as if it were a labral tear causes severe pain, stiffness, and restricted external rotation 1.

Treatment Algorithm

1. Asymptomatic Buford Complex (Incidental Finding)

• No treatment required
• Document the finding to prevent future surgical misidentification
• This is a normal variant 1

2. Buford Complex with Anterior Shoulder Instability

The modern approach uses the cord-like MGHL as a reconstructive tissue 2:

• Arthroscopic stabilization technique:
  • Use the cord-like MGHL to reconstruct a "neo-labrum"
  • Reattach the MGHL to the anterior glenoid rim
  • Combine with anteroinferior glenohumeral ligament plication
  • This provides an efficient alternative to bone block procedures 2

Important evolution in thinking: Traditional teaching discouraged MGHL reattachment due to concerns about external rotation restriction 2, 3. However, recent evidence from 2024 demonstrates that proper arthroscopic stabilization using the MGHL can achieve satisfactory outcomes without severe motion restriction 2, 3.

Consider bone block procedures (Latarjet) if:

• Significant glenoid bone loss is present
• Patient has failed soft tissue stabilization
• Note: Patients with Buford complex may have more anteverted glenoids 4

3. Buford Complex with SLAP Tear

Specific surgical technique 5:

• Perform standard type II SLAP repair with suture anchors
• Transect the cord-like MGHL at the glenoid equator
• Fix the proximal MGHL segment to the anterosuperior glenoid rim (which lacks labral tissue) to augment the SLAP repair
• Leave the distal MGHL segment free to preserve external rotation
• This technique showed significant improvement in UCLA scores (14.3 to 32.1) and Constant scores (39.7 to 85.0) at mean 44-month follow-up 5

4. Isolated Tear of the Cord-like MGHL

Rare but documented pathology 6:

• Can present with pain and stiffness mimicking frozen shoulder
• Arthroscopic repair of the torn MGHL to restore original anatomy
• This represents a true pathologic condition requiring intervention 6

Key Technical Considerations

Preoperative imaging challenges:

• Buford complex is difficult to identify on MRI preoperatively 2
• Remains primarily an arthroscopic diagnosis 2
• High index of suspicion needed during arthroscopy

Intraoperative identification:

• Look for absent anterosuperior labrum from 1-3 o'clock position
• Identify thick, cord-like MGHL originating directly from superior labrum/biceps anchor
• Do NOT mistake this for a detached labral tear

Clinical Context for a 20-Year-Old

At age 20, the most likely scenarios are:

1. Traumatic anterior instability (most common in young active patients) - use MGHL reconstruction technique 2
2. SLAP tear (overhead athletes) - use the transection and augmentation technique 5
3. Incidental finding during arthroscopy for other pathology - leave it alone

Recent evidence suggests patients with Buford complex may be at higher risk for SLAP tears compared to those without this variant 1, making thorough evaluation essential.

Avoiding Common Pitfalls

• Never repair an asymptomatic Buford complex - this creates iatrogenic pathology
• Do not confuse the cord-like MGHL with a "Bankart variant" or detached labrum
• Document the finding clearly in operative notes to prevent future confusion
• Consider glenoid version - these patients may have more anteverted glenoids requiring different instability management 4
