Distal Biceps Tendon Rupture in Raleigh, NC

You felt a sudden pop in the front of your elbow, followed by pain, bruising, and weakness. Your biceps muscle may have balled up toward your shoulder. This is a distal biceps tendon rupture — a complete tear that almost always requires prompt surgical repair in active patients.

What Is a Distal Biceps Rupture?

The biceps muscle has two heads that attach at the shoulder and one distal tendon that attaches to the radial tuberosity in the forearm. A distal biceps rupture is a complete or partial tear of this tendon at its forearm attachment. It is most common in men aged 40–60 during heavy lifting — typically when an unexpected load forces the elbow to extend while the biceps is contracting.

Without surgical repair, patients lose approximately 30–40% of supination strength (rotating the forearm palm-up) and 20–30% of flexion strength. For active patients who use their arms for work, sport, or lifting, this deficit is significant and does not improve with time.

Surgical Repair Is Time-SensitiveDistal biceps tendon repairs produce the best outcomes when performed within 3–4 weeks of injury. As the tendon retracts and scar tissue forms, repair becomes technically more difficult and results deteriorate. If you felt a pop in your elbow and have visible deformity of the biceps muscle, seek evaluation immediately. Call (919) 781-5600.

Pop

Sudden, felt or heard

30–40%

Supination strength lost without repair

3–4 wks

Window for optimal surgical repair

6 months

Return to heavy lifting after repair

Symptoms

Sudden sharp pain in the front of the elbow — often described as a pop or snap
Immediate significant weakness — difficulty lifting anything or rotating the forearm
Visible bruising at the elbow crease and inner forearm within 24–48 hours
Popeye deformity — the biceps muscle bunches up toward the shoulder when flexing
A palpable gap at the elbow where the tendon was attached
The Ruland hook test: normally you can hook a finger under the intact biceps tendon — with a complete rupture, there is nothing to hook

Treatment

Surgical Repair (Recommended for Active Patients)

The distal biceps tendon is reattached to the radial tuberosity using a suture anchor technique through a small incision at the elbow crease. Dr. Chambers performs this procedure as an outpatient surgery. The repair is strong enough to begin early range-of-motion exercises within the first week.

Recovery timeline:

Weeks 1–6: Elbow motion with protected weight bearing
Months 2–4: Progressive strengthening
Months 4–6: Return to heavy lifting, manual work, overhead athletes
Month 6: Full unrestricted return for most patients

Non-Surgical (Selected Cases)

Non-surgical treatment is considered for elderly, low-demand, or medically unfit patients. The strength deficit is permanent but may be acceptable for someone who does not lift heavy or participate in demanding sport or manual work.

How do I know if my biceps tendon is ruptured or just strained? +

A complete distal biceps rupture produces a visible asymmetry — the biceps muscle belly on the injured side sits higher on the arm than the uninjured side (Popeye sign). There is also significant weakness with palm-up rotation and elbow flexion against resistance. A sprain produces pain without the visible deformity or significant strength loss. MRI can confirm the diagnosis when there is any doubt.

Can a partial biceps tendon tear be treated without surgery? +

Partial distal biceps tears (where the tendon is frayed but not completely ruptured) are sometimes managed non-surgically with PT and PRP injection. However, partial tears that cause persistent pain and functional limitation despite conservative care, or that progress to complete rupture, ultimately require surgical repair.
