Distal Biceps Tendon Rupture: Diagnosis and Surgery in Vienna
Biceps tendon rupture at the elbow – treated by Associate Professor Dr. Gustav Timmel, Director of the Sports Medicine Clinic at the Floridsdorf Hospital
A distal biceps tendon tear is the tearing of the biceps tendon from its attachment to the radius near the elbow. Those affected typically feel a sudden, often audible tearing sensation during a jerky movement, followed by a noticeable loss of strength when bending the elbow and rotating the forearm. Often, the muscle belly visibly slips toward the shoulder. Unlike a tear of the long biceps tendon at the shoulder, a distal tear generally requires surgery—and time is of the essence. In Vienna, Orthopedic Surgeon Dr. Gustav Timmel treats this injury surgically using the tension-slide technique.
OVERVIEW
Who performs surgery for distal biceps tendon tears in Vienna?
Distal biceps tendon tears are treated surgically in Vienna by OA Dr. Gustav Timmel, a specialist in orthopedics and traumatology with a focus on sports injuries and the director of the Sports Outpatient Clinic at the Floridsdorf Clinic. The initial examination, diagnostic testing, and all follow-up visits take place at the practice located in the MSV Medical Center at Invalidenstraße 11/2a, 1030 Vienna. Upon request, the surgery can also be performed at a private hospital of your choice.
Prompt surgical care can be ensured.
What is a distal biceps tendon tear?
The biceps (Musculus biceps brachii) transmits its force to the forearm at the elbow via two structures.
The most important and by far the strongest of these is the distal biceps tendon. It attaches to a bony protrusion on the radius, the tuberosity of the radius. It transmits the force for two movements: flexion of the elbow and outward rotation of the forearm, known as supination. Supination is the movement used to turn a screwdriver or operate a doorknob.
In addition, the Lacertus fibrosus extends from the biceps into the fascia of the forearm—a fascial band that also transmits force but is significantly weaker than the tendon itself. In cases of a distal biceps tendon rupture, this band is often torn as well.
If the distal biceps tendon tears, the muscle loses its strong attachment to the forearm. It retracts upward toward the shoulder, forming a visible bulge there. The lacertus fibrosus cannot compensate for the tendon’s pulling force, so the loss of function is clearly noticeable—unlike in the more common tear of the long biceps tendon at the shoulder, where the short biceps tendon largely takes over the function.
How common is a distal biceps tendon rupture?
How can I tell if I have a biceps tendon tear at the elbow?
A distal biceps tendon tear usually occurs without warning; it happens all at once. The typical sequence is as follows:
- A sudden, often audible popping sound in the crook of the elbow during a forceful movement, frequently accompanied by a sharp pain
- The acute pain subsides after a short time—this is deceptive because many people who are affected underestimate the injury as a result
- Visible deformation of the upper arm: The muscle belly slides upward toward the shoulder, the upper arm appears short and compressed, and the crook of the elbow feels hollow. The severity of these symptoms varies.
- Bruising and swelling in the crook of the elbow and on the forearm, often not appearing until one to two days later
- Loss of strength when bending the elbow
- A noticeable loss of strength when rotating the forearm outward—opening bottles, using a screwdriver, and holding a full pan become noticeably more difficult
Important: An upper arm that looks normal does not rule out a tear. How far the muscle retracts upward also depends on whether the lacertus fibrosus is torn as well. If this fascial strand remains intact, it partially restrains the muscle—the bulge on the upper arm is then less pronounced, even though the tendon is completely torn. Therefore, the decisive factor is not appearance alone, but rather the loss of strength when flexing and, above all, when rotating the forearm outward.
The visible bulge of muscle is colloquially referred to as the "Popeye sign ."
How is a distal biceps tendon tear diagnosed?
Diagnosis begins with a medical interview and a clinical examination. The patient’s description of the accident, the palpable gap in the elbow crease, and the strength test involving flexion and external rotation usually provide a clear indication. Imaging techniques are also used to supplement the diagnosis:
| Untersuchung | Wozu sie dient |
|---|---|
| Klinische Untersuchung | Tastbefund in der Ellenbeuge, Kraftprüfung für Beugung und Supination, Seitenvergleich |
| Ultraschall | Schnell verfügbar, dynamisch – zeigt Sehnenkontinuität, Flüssigkeit und Hämatom, direkt in der Ordination durchführbar |
| MRT | Beurteilt Rissform (vollständig oder teilweise), Ausmaß der Sehnenretraktion und den Zustand des Sehnengewebes – Grundlage für die OP-Planung |
| Röntgen | Schließt knöcherne Begleitverletzungen aus; dient nach der Operation zur Kontrolle der Buttonlage |
Why should surgery for a distal biceps tendon tear be performed within three weeks?
A distal biceps tendon rupture is not an emergency requiring immediate surgery, but it is time-sensitive. The tendon should be surgically repaired within the first three weeks after the rupture. After that, it retracts toward the upper arm and heals in that position.
If this has already occurred, the full original length of the tendon may no longer be available during surgery to reattach it to its anatomical attachment site. In this case, it may be possible to lengthen the tendon. For example, an autologous tendon can be harvested from the thigh area (hamstrings) and used to lengthen the distal biceps tendon.
This procedure is a significantly more invasive one for both the surgeon and the patients and involves a correspondingly greater amount of effort and additional stress.
Therefore, if a distal biceps tendon tear is suspected, the evaluation should not be delayed—even if the pain subsides after a few days.
Surgery or conservative treatment?
The decision to perform surgery is not based solely on the test results, but is made during a consultation. At his office in the MSV Medical Center, Dr. Timmel takes the time to address the questions that make all the difference:
- How much strain is placed on the arm in daily life and at work—especially when twisting and lifting?
- What are your athletic goals, and at what level?
- How long ago did the tear occur, and how far has the tendon already receded?
- What comorbidities and individual risk factors are present?
- What are the expectations regarding the power that should be available after the treatment?
Based on this, Dr. Timmel discusses the realistic outcomes of both options—with and without surgery—and what each means for work, sports, and daily life. The decision is made jointly.
Without surgery, the tendon will not heal back to its original attachment site. Range of motion and daily functioning remain satisfactory in many cases, but there is a measurable loss of strength—especially when rotating the forearm outward. For people whose jobs or sports involve high physical exertion, this is usually the deciding factor.
Tension Slide Technique During a Biceps Tendon Surgery
How does Dr. Timmel perform surgery for a distal biceps tendon tear?
Dr. Timmel reattaches the distal biceps tendon using the tension-slide technique with an endobutton.
Here's how the process works:
The torn tendon is located through an incision in the elbow crease and mobilized from its retracted position. Its end is reinforced with a high-strength suture. A channel is drilled into the radius at its original attachment site, the tuberosity of the radius. A small metal plate anchor—the “button”—is guided through this channel and lies across the opposite side of the bone. Using a sliding suture system, the tendon is then carefully pulled into the bone canal and secured there at the desired tension. It is precisely this controlled pulling that gives the technique its name: tension slide.
What this means for patients:
| Zugang | Ein Zugang in der Ellenbeuge |
| Fixierung | Endobutton mit Gleitfadensystem, kein Fremdmaterial im Weichteilgewebe erforderlich |
| Spannung der Sehne | Wird während der Operation kontrolliert eingestellt |
| Primärstabilität | Erlaubt eine frühzeitige, kontrollierte Beübung nach ärztlicher Vorgabe |
| Röntgenkontrolle | Abschlussröntgen zur Dokumentation der Buttonlage |
Postoperative Care: The Timeline
After refixation, the tendon must heal back to the bone. For this reason, the arm is initially rested, and the load is gradually increased. An overview of the process:
| Zeitraum | Was in dieser Phase gilt |
|---|---|
| Woche 0 bis 2 | Gipsschiene bis zur Nahtentfernung |
| Woche 2 bis 8 | Der Arm darf frei bewegt werden, aber ohne Belastung |
| Ab Woche 8 | Beginn des Belastungsaufbaus |
| Ab Woche 12 | Gewichtstraining |
| Ab dem 3. Monat | Schwere körperliche Tätigkeit |
What "without stress" actually means
In the six weeks after the cast is removed, the rule of thumb is: don’t lift anything heavier than a coffee cup. And don’t turn a key in a lock. That may sound like a minor thing, but it’s exactly the movement that matters: The biceps is the forearm’s primary external rotator, the supinator. When turning a key or a doorknob, it pulls with full force on the recently reattached tendon.
Dr. Timmel determines the specific treatment plan during follow-up visits and adjusts it based on the healing process.

Frequently Asked Questions About Distal Biceps Tendon Tears
Can a distal biceps tendon tear heal on its own?
No. A tendon that has been completely torn does not regrow on its own at its attachment to the radius. Without surgery, it heals in a retracted position. Range of motion and everyday function often remain satisfactory, but there is a loss of strength—especially when rotating the forearm outward.
How can I tell the difference between a muscle fiber tear and a biceps tendon tear?
A muscle fiber tear causes pain in the muscle belly, usually without any change in the shape of the upper arm. Signs of a distal biceps tendon tear include a sudden tear in the elbow crease, a palpable gap there, and a muscle belly that has visibly shifted upward. Only a medical examination using ultrasound or MRI can provide a definitive diagnosis.
Do I need surgery right away?
A distal biceps tendon rupture does not require emergency surgery, but should be treated surgically within the first three weeks after the rupture. After that, the tendon retracts toward the upper arm and forms scar tissue there, which makes the procedure significantly more complicated. Even if the pain subsides after a few days, the examination should therefore not be postponed.
What happens if the crack is detected too late?
What is the tension-slide technique?
In the tension-slide technique, the torn biceps tendon is pulled in a controlled manner through a system of guide wires into a drill channel in the radius and secured there with an endobutton. The tension of the tendon can be precisely adjusted during the operation. Dr. Timmel uses this procedure for the refixation of distal biceps tendon tears.
How long will I be on sick leave after the surgery?
That depends on your occupation. For heavy physical work, you should not resume such activities until at least three months after the surgery. You’ll wear a plaster cast for the first two weeks; after that, you may move your arm freely for six weeks, but you must not put any weight on it. Dr. Timmel will discuss with you individually when you can resume a primarily sedentary job.
What is Lacertus fibrosus, and why is it important?
The Lacertus fibrosus is a fascial strand that extends from the biceps into the fascia of the forearm. It also transmits force, but is significantly weaker than the distal biceps tendon and is often affected in the event of a tear. If it remains intact, it can partially hold the retracted muscle in place—the typical bulge on the upper arm is then less pronounced. An upper arm that looks normal therefore does not rule out a tendon tear.
Will there be a scar?
Yes, the incision in the crook of the elbow leaves a scar. Dr. Timmel will discuss the size and location of the scar during the preoperative consultation.
Will I be able to do strength training again after the surgery?
Yes. Weight training can generally be started twelve weeks after surgery. Before that, the load is gradually increased: two weeks in a cast, followed by six weeks of unrestricted movement without weight-bearing, and beginning in the eighth week, the load is gradually increased. The goal of the surgery is to restore the strength needed for flexion and external rotation of the forearm—for people who place heavy strain on their arm during sports or at work, this is the primary reason for the procedure.
