How Does SCR Help If My Humeral Head Keeps Riding Upward?
Superior capsular reconstruction (SCR) restores the superior capsule of the shoulder, which limits the upward movement of the humeral head. This procedure stabilizes the joint, keeps the humeral head centered in the glenoid, and reduces abnormal contact with the acromion (the bony arch over the shoulder joint). SCR also restores normal shoulder biomechanics and improves glenohumeral stability, which reduces shoulder pain.
At Total Orthopedics & Sports Medicine, our surgeons perform SCR using advanced arthroscopic and open surgery techniques. During the procedure, we protect the surrounding tissues, including the remaining rotator cuff tendons and the subacromial bursa. This careful surgical approach preserves your shoulder structures, supports healing, and improves long-term function. Call 855-321-6784 to schedule your consultation.
Can SCR Restore Stability When the Humeral Head Shifts Upward?
Yes, if your humeral head shifts upward, superior capsular reconstruction (SCR) can restore shoulder stability. This shoulder surgery rebuilds the superior capsule and centers the humeral head in the glenohumeral joint, which prevents further upward migration of the humeral head. SCR also supports internal and external rotation, maintains proper scapular position, and enhances overall upper limb function.
Moreover, according to ScienceDirect, superior capsular reconstruction (SCR) restores shoulder mechanics after an irreparable supraspinatus tendon tear. In the study, an irreparable tear reduced functional abduction force by 25–30% and increased superior humeral head migration by nearly 100%. After the treatment, SCR reduced abnormal migration by about 90–100%, restoring humeral head position at 0° and 30° of abduction and preserving near-normal axial rotation.
What Criteria Do Surgeons Use to Determine Candidacy for SCR?
To determine eligibility for SCR, our shoulder specialist, Dr. Richard McCormack, assesses your symptoms, X-rays, MRI scans, and functional limitations. He also evaluates the extent of the rotator cuff tear and analyzes rotator cuff tendon quality, muscle atrophy, and fatty degeneration to ensure the SCR procedure effectively restores shoulder function.
In addition to these factors, Dr. Richard measures your shoulder’s range of motion using the following tests:
- Active and passive forward elevation test: Measures how far you can lift your arm forward.
- External rotation test: Checks your ability to rotate the upper arm outward.
- Full internal rotation assessment: Measures how far you can rotate your arm inward behind your back.
- Cross-body adduction test: According to Physiopia, the cross-body adduction test assesses the integrity of the acromioclavicular (AC) joint
- Pseudoparalysis test: Identifies severe weakness or inability to lift the arm due to rotator cuff dysfunction.
After that, our surgeon may check deltoid muscle strength and assess overall shoulder stability. He also reviews your history of prior shoulder surgeries and injuries to confirm that your shoulder can safely undergo SCR. Call 855-321-6784 to schedule your appointment with Dr. McCormack.
Why Is SCR Often Recommended For Younger Or Active Patients?
Shoulder surgeons often recommend Superior capsular reconstruction (SCR) for younger or active patients because it restores shoulder stability without replacing the joint. Many younger patients have irreparable rotator cuff tears but still have healthy cartilage and good bone quality. To preserve this healthy cartilage, surgeons perform SCR to maintain normal joint mechanics and limit further cartilage wear.
What’s the Difference Between Rotator Cuff Repair and SCR for Upward Riding?
Rotator cuff repair reattaches torn tendons back to the bone, while SCR uses a graft to recreate the superior capsule when the rotator cuff is irreparable, preventing upward movement. Other than that, rotator cuff repair restores the natural tendon’s dynamic function, which helps muscles to stabilize the humeral head during shoulder motion.
On the other hand, SCR restores shoulder stability by replacing the damaged superior capsule rather than repairing the tendon itself. The graft acts as a mechanical barrier that prevents the humeral head from moving upward when the rotator cuff cannot heal. This restored stability keeps the joint centered, improves glenohumeral mechanics, and allows better shoulder movement.
Additionally, according to a SagePub study, arthroscopic superior capsular reconstruction (aSCR) has better outcomes than arthroscopic rotator cuff repair (aRCR). Compared with the aSCR group, the aSCR group had about 9% greater forward flexion (161° vs 148°) and approximately 37% lower pain scores (pVAS 1.03 vs 1.64). The healing rate was also significantly higher with SCR (87.9%) compared with RCR (60.6%, P = .022).
What Type of Graft Is Used in Superior Capsular Reconstruction?
In superior capsular reconstruction (SCR), surgeons most commonly use an acellular dermal allograft or a fascia lata autograft. Acellular Dermal allografts are made from donated human tissue and provide consistent thickness and strength. In contrast, fascia lata autografts use the patient’s own thigh tissue and offer strong mechanical support with good biological healing. In some cases, shoulder specialists may also use the following grafts to restore shoulder function:
- Long head of the biceps tendon (LHBT) autograft
- Porcine dermal xenograft
- Hamstring tendon autograft
- Synthetic graft materials
- Tibialis anterior allograft
- Hybrid grafts (combined tendon and dermal tissue)
How Does Tendon Atrophy and Fatty Infiltration Affect SCR Outcomes?
Tendon atrophy and fatty infiltration significantly reduce the success of Superior Capsular Reconstruction (SCR). For example, if you have advanced fatty infiltration of the rotator cuff muscles, those muscles cannot generate enough force to support shoulder motion after surgery. Even when the graft restores stability, poor muscle quality can limit functional improvement.
Similarly, if you have tendon atrophy, the remaining rotator cuff tendons get thin, shortened, and less responsive. These weakened tendons cannot provide enough dynamic support to control the humeral head during arm elevation. As a result, the graft overworks to support the joint function, which can reduce the overall effectiveness of SCR.
What is the Average Recovery Time After SCR?
The average recovery time after SCR is 6 to 12 months, depending on the size of the tear, graft type, and rehabilitation progress. If you have a massive tear and significant tissue damage, your recovery may take 12 months or more. However, if the tear is minor and you follow a structured rehabilitation plan, you may regain function after 6 months.
Tip: To speed up the healing process, avoid heavy lifting, overhead reaching, contact sports, and activities that increase the risk of falling.
What Are the Most Common Causes of SCR Failure?
Graft rupture at the humeral attachment site, poor graft healing, and loss of graft tension are the most common causes of superior capsular reconstruction (SCR) failure. Severe rotator cuff muscle atrophy, advanced fatty infiltration, and overuse of the shoulder also increase the risk of SCR failure. Here are some additional causes of SCR failure:
- Inadequate graft thickness or mechanical strength
- Poor bone quality at graft fixation sites
- Advanced shoulder arthritis
- Recurrent anterior shoulder instability or fractures
- Infection or inflammatory reaction
- History of prior failed shoulder surgeries

FAQs
What Causes a High-Riding Humeral Head?
A high-riding humeral head most commonly results from a chronic or massive rotator cuff tear. In this condition, the rotator cuff muscles fail to stabilize the shoulder joint, leading to upward humeral movement. As a result, the deltoid muscle pulls the upper arm bone upward, which worsens joint mechanics over time.
What Prevents the Humeral Head From Sliding Upward?
The supraspinatus (primary rotator cuff muscle) prevents the humeral head from sliding upward by stabilizing it within the glenoid socket. It applies a downward and compressive force that balances the upward pull of the deltoid muscle during arm elevation. The infraspinatus, teres minor, and subscapularis also keep the humeral head centered and prevent upward motion during shoulder movement.
How Do I Know if My “Upward Migration” Is Mild or Severe?
If you experience occasional shoulder pain and mild weakness, your upward migration may be mild. However, if you have constant shoulder discomfort, significant weakness, difficulty lifting the arm overhead, or loss of normal shoulder motion, the upward migration may be severe. X-rays or MRI scans can also help confirm the severity of the migration by showing the degree of humeral head elevation.
What Conditions Require SCR Surgery?
You may need a superior capsular reconstruction (SCR) surgery if you have massive, irreparable rotator cuff tears that cannot be repaired with standard surgical repair. You may also need the SCR procedure if you have persistent shoulder pain or shoulder instability that does not improve with conservative treatments.
What Are the Most Common Reasons SCR Doesn’t Work?
The SCR may not work if the graft fails to heal properly or loses tension after surgery. Weak rotator cuff or deltoid muscles, shoulder arthritis, and improper surgical technique may also reduce the success rate of SCR. These issues prevent the graft from restoring stability and lead to persistent pain or dysfunction.
Does the Type of Graft Used in SCR Affect Shoulder Stability?
Yes, the type of graft in SCR significantly affects shoulder stability. For instance, fascia lata autografts provide strong tensile support, which helps restore superior stability more effectively. Similarly, Dermal allografts improve stability but may offer less support if the graft is thin. In contrast, synthetic grafts provide initial support but lose effectiveness over time, which can affect long-term shoulder stability.
How Long Will I Need to Wear a Sling After SCR?
After superior capsular reconstruction (SCR), you typically need to wear a shoulder sling for about 4 to 6 weeks, depending on the size of the tear. For example, larger or more complex tears often require sling use for 6 weeks. But if you have minor tears, you can stop using the sling after 4 weeks, as advised by your surgeon.
