A persistent ache at the front of the shoulder that worsens with overhead activity, combined with a catching or snapping sensation during rotation, can indicate a biceps pulley lesion. It is a condition frequently missed on initial assessment but highly amenable to arthroscopic treatment when accurately diagnosed.
Dr. Kushalappa Subbiah offers expert evaluation and surgical management of biceps pulley lesions at his Bangalore clinics, with specialist training in complex shoulder pathology.
What is Biceps Pulley Lesion?
The biceps pulley is a sling-like structure at the top of the shoulder joint formed by ligamentous tissue from the subscapularis and supraspinatus tendons. It holds the long head of the biceps tendon within the bicipital groove as the shoulder moves. When this pulley system is injured or torn, the biceps tendon loses its normal stabilisation and begins to move abnormally within the groove, causing pain, catching, and progressive shoulder dysfunction.
Biceps pulley lesions are strongly associated with rotator cuff tears, particularly of the subscapularis tendon, and often present as part of a more complex shoulder pathology rather than in isolation.
Types of Biceps Pulley Lesion
Causes
Acute trauma such as a sudden fall, overhead impact, or forceful shoulder movement can directly rupture the pulley ligaments. Degenerative wear from repetitive overhead activities, particularly in older patients, is the more common mechanism. The condition is frequently associated with subscapularis tears and subacromial impingement, making it important to assess the whole shoulder rather than an isolated structure.
- Pain at the front or top of the shoulder, particularly with overhead movement, lifting, or rotation
- A snapping, clicking, or catching sensation during shoulder movement, often described as something slipping inside the joint
- Weakness when lifting the arm or performing pushing or overhead movements
- Tenderness along the bicipital groove when the shoulder is palpated
Diagnosis
Clinical examination focuses on assessing the biceps tendon and rotator cuff, including the subscapularis. MRI arthrogram is the most useful imaging investigation for identifying pulley lesions and any associated rotator cuff pathology. Ultrasound can also be used to assess the biceps tendon in the groove dynamically.
Treatment
Arthroscopic Repair or Biceps Tenodesis
Treatment is guided by the severity of the pulley disruption and the presence of associated pathology. When the pulley is torn and the biceps tendon is unstable, Dr. Kushalappa performs arthroscopic repair of the pulley tissue where possible, or a subpectoral biceps tenodesis when the tendon or pulley tissue is too degenerate for reliable primary repair. Associated subscapularis tears are addressed in the same procedure.
