Bicep Tendon Tear Treatment

The biceps has tendons at both ends, and which end tears changes almost everything about what happens next. A tear at the shoulder frequently needs no surgery at all. A complete tear at the elbow usually does, and the window for repairing it well is measured in weeks.

Steven Struhl, MD has performed more than 5,000 arthroscopic procedures since entering practice in 1991. He is board certified in orthopedic surgery and holds separate board certification in sports medicine and arthroscopic surgery, completed his sports medicine fellowship at Penn State University, and is a member of the Arthroscopy Association of North America. Whether a torn biceps tendon needs repair depends heavily on which end tore and on what the arm is asked to do, and that is a conversation rather than a rule.

Types of Biceps Tendon Tear

• Partial Tear: the tendon frayed and damaged but still continuous.
• Complete Tear: the tendon separated into two parts, no longer connecting muscle to bone.
• Proximal Tear at the Shoulder: involving the long head of the biceps where it enters the shoulder joint, and accounting for the large majority of biceps ruptures.
• Distal Tear at the Elbow: involving the attachment to the forearm bone, far less common and considerably more consequential.
• Short Head Tears: genuinely rare, since the short head has a separate attachment that shares the load.

Biceps Tendon Tear at the Shoulder

The long head of the biceps runs through a groove at the top of the arm bone and into the shoulder joint, where it is exposed to the same wear that produces rotator cuff problems. Tears here are usually degenerative, developing over years, and they frequently occur alongside cuff tears rather than in isolation.

When the long head ruptures, the muscle belly bunches toward the elbow, producing the characteristic Popeye deformity. Most patients lose relatively little strength, because the short head continues to work, and many are treated without surgery for that reason. Repair or tenodesis is considered for younger patients, for those doing heavy manual work, for persistent cramping pain, and for patients who find the cosmetic change unacceptable.

Biceps Tendon Tear at the Elbow

Distal biceps rupture is a different problem. It typically happens in a single event, a heavy lift or a sudden load on a flexed elbow, most often in men in their forties and fifties, and patients usually feel a pop and see immediate bruising.

Left unrepaired, a complete distal rupture costs substantial supination strength, meaning the ability to rotate the forearm, and a measurable amount of flexion strength. Surgical repair is recommended for most active patients, and it is meaningfully easier within the first two to three weeks, before the tendon retracts and scars.

Causes and Risk Factors

• Sudden Eccentric Load: the biceps contracting against a force that straightens the elbow.
• Repetitive Overhead Use: wearing the long head over years.
• Age: tendon quality declining, with most ruptures occurring after forty.
• Smoking: an established risk factor for tendon rupture.
• Corticosteroid Use: systemic or injected, weakening the tendon.
• Anabolic Steroids: associated with tendon rupture in weightlifters.

Biceps Tear Symptoms

• A Sudden Pop: usually felt, frequently heard, particularly in distal tears.
• Sharp Pain at the Shoulder or Elbow: localizing to the end that tore.
• Popeye Deformity: a visible bulge as the muscle retracts.
• Bruising: developing over the following days.
• Weakness Rotating the Forearm: the most functionally significant loss in distal tears.
• Cramping: aching in the muscle with use, common after long head rupture.

Diagnosis and Treatment

Examination is usually sufficient for a distal rupture, where the tendon cannot be felt in the crease of the elbow and supination strength is clearly reduced. MRI confirms the diagnosis, defines whether the tear is partial or complete, shows how far the tendon has retracted, and identifies associated rotator cuff or labral injury at the shoulder.

• Observation: appropriate for many long head tears in older or less active patients.
• Physical Therapy: restoring motion and strengthening what remains.
• Anti Inflammatory Measures: for pain control during the early period.
• Tenodesis: reattaching the long head lower down, outside the joint, which addresses pain and deformity.
• Distal Repair: reattaching the tendon to the radius with anchors or a button, generally recommended for active patients.

Recovery after repair involves a period of protection, roughly six weeks, followed by progressive motion and strengthening, with heavy lifting resuming around four to six months. Complications after biceps repair are uncommon, and the ones worth knowing are numbness or weakness in the forearm, formation of bone within the soft tissue, stiffness, and retearing.

Schedule a Biceps Tendon Evaluation in New York City

A pop at the elbow followed by bruising and difficulty rotating the forearm should be evaluated within days rather than weeks, because the repair is straightforward early and considerably harder later. Dr. Struhl evaluates biceps tendon injuries at his Manhattan and Westchester offices. Contact Shoulders & Knees to schedule a consultation.
