What is Distal Biceps Tendon Rupture?
A distal biceps tendon rupture refers to a complete tear of the biceps tendon at the elbow. It typically occurs in 30-50 year old males when trying to perform an elbow contraction such as an arm curl, or a lifting, throwing or catching activity that is too heavy or too overloaded.
Distal biceps tendon ruptures occur suddenly, with associated:
- Popping, snapping or giving way of the elbow
- Immediate pain at the elbow
- Immediate weakness of the elbow
- Muscle bunching and deformity of the upper arm (popeye deformity)
Following a distal biceps tendon rupture, the biceps muscle shortens, leaving a disfigured bunched up muscle in the upper arm. This disfigurement is sometimes described as popeye deformity, although true popeye deformity is the result of tearing a biceps tendon at the shoulder rather than the elbow. A ruptured tendon cannon heal by itself and will need surgery to be repaired.
If you have suffered a distal biceps tendon rupture, you only have a short amount of time before extensive muscle shortening occurs and the biceps tendon becomes increasingly difficult to surgically repair. If your tendon cannot be retrieved, you may be left with upper arm deformity and weakness of the elbow permanently.
If you suspect you may have a biceps injury, it's important you get it seen to quickly. Dr Gupta will be able to help confirm your condition and start organising what you need to do next to get it repaired.

Symptoms of Distal Biceps Tendon Rupture
Distal biceps tendon rupture may have the following symptoms:
- Deformity of the biceps muscle
- Bruising at the front of the elbow
- Swelling at the front of the elbow
- A gap in the elbow where the tendon used to be
- Weakness when bending the elbow
- Weakness when pronating the forearm (an action like turning a screwdriver)
What Causes Biceps Tears?
Distal biceps tendon rupture occurs when forcefully straightening a contracting elbow, typically in 35-50 year old males. This movement occurs when lowering something heavy, or by grabbing something to slow you down as you are running by. Throwing or catching large heavy objects or playing with small children are the type of activities which can lead to biceps rupture.
Males who are older than 30, who smoke and who may be using corticosteroids are most at risk of sustaining a distal biceps tendon rupture.
Sports Injuries Causing Biceps Tears
The famous sport known as the "Caber Toss", where a large heavy log is thrown in competition is well known to cause bicep rupture at the elbow. The rupture occurs at the point just prior to throwing the log where the competitor straightens the elbow against the resistance of the log in order to throw it. If the log is too heavy, a sudden rupture of the distal biceps tendon may occur.
Workplace Injuries Causing Biceps Tears
Catching large heavy objects when they fall is a common cause of distal biceps tendon ruptures at work. A reaction to catch a box falling from a table or conveyor belt, playing with children or catching a child who may be about to run into traffic, or someone dropping an unexpected heavy item into a bag you may be carrying may cause sudden biceps tendon rupture at the elbow.
Diagnosing a Biceps Tear
Diagnosing a biceps tendon rupture at the elbow is a multi-step procedure:
- Understand the nature of the injury (sports, work, accident, overuse etc)
- Determine the cause of the injury (impact, collision, fall, repetitive/slow onset)
- Understand the context of the suffering (age, return to sport, work, impact on daily living)
- Perform a physical examination to ascertain pain and range of movement
- Perform specialised elbow tests to confirm diagnosis
Complete Rupture at the Elbow
Complete distal biceps rupture tears are obvious as you will see a clear muscle bunching deformity in the upper arm. The finger hook test is a specific physical examination used to confirm the attachment of the biceps tendon at the elbow. If the tendon attachment is ruptured, a hook cannot be performed and rather a gap will be felt instead. A comparison to the patient's non affected side is always useful to determine the patient's sense of normal.
Imaging such as X-Ray and MRI and further diagnostic tests are used to determine whether there are any fractures contributing to the condition and to determine if the biceps tendon has started to retract up the upper arm away from the elbow. Early diagnosis and treatment of biceps injury is extremely important to avoid risk of a permanent injury.
Treatment for a Distal Biceps Tendon Rupture
Treatment of biceps tendon rupture at the elbow should always begin with a thorough diagnosis of your condition to understand the severity of the condition in the context of your age and how your elbow function may impact your job, or sport, and life.
Surgical treatment for ruptures is advisable if you wish to regain normal function of your elbow and wrist to minimise the deformity of the upper arm. Early treatment of biceps tendon rupture at the elbow is extremely important to minimise the possibility of retracted biceps tendon which makes repairing the condition difficult.
Surgical Repair involves retrieving the retracted biceps tendon from the upper arm and re-attaching it to the forearm at the elbow.
Dr Gupta is a skilled tendon repair surgeon and has retrieved many distal biceps tendons from the upper arm with minimal scarring.
