Elbow conditions
Distal biceps ruptures
A tear of the biceps tendon where it attaches at the elbow, usually a sudden lifting injury that is most often repaired surgically.
Tendon tear at the elbow
Common in lifters
Usually surgically repaired
What is a distal biceps rupture?
The biceps has two attachments at the elbow end, the distal biceps tendon anchors the muscle to the forearm bone and powers bending the elbow and rotating the palm upward. A distal biceps rupture is a tear of this tendon off the bone.
It typically happens when the elbow is forced straight against a heavy load. Because the tendon loses significant strength when torn, surgical repair is usually recommended in active patients.
Overview
At a glance
Repair early
Like other tendon ruptures, the distal biceps is best repaired within the first few weeks, before it retracts and scars.
Symptoms & signs
Signs of a distal biceps rupture
The injury is usually sudden and recognizable.
A sudden pop at the front of the elbow during a heavy lift
Pain and bruising at the elbow and into the forearm
Weakness bending the elbow and turning the palm upward
A change in the shape of the biceps as the muscle balls up
Cramping and fatigue with use of the arm
Causes & risk factors
What causes it
Almost all occur with a sudden eccentric load.
Heavy lifting
Forcing the elbow straight against a heavy weight is the classic cause.
A sudden load
Catching a falling object or a forceful pull can tear the tendon.
Middle-aged men
Most common in men in their 40s and 50s.
Tendon wear
Degeneration weakens the tendon and predisposes it to rupture.
Treatment options
How distal biceps ruptures are treated
Active patients are usually best served by surgical repair.
- Considered for lower-demand patients or partial tears
- Accepts some loss of rotation and bending strength
- Rest and a gradual return to activity
- Therapy to optimize remaining strength
- The tendon is reattached to the forearm bone
- Best done within the first weeks after injury
- Restores bending and rotation strength
- Preferred for active patients

Repair is performed as a distal biceps repair.
Recovery
What recovery looks like
Recovery after repair is staged over several months.
Protect
A splint or brace protects the repair early on.
Restore motion
Therapy gradually returns elbow motion in a protected range.
Strengthen
Progressive strengthening rebuilds bending and rotation power.
Full use
A staged return to lifting and full activity.
FAQ
Common questions
-
The tendon does not reattach on its own. Non-surgical care is an option for lower-demand patients, but it leaves a lasting loss of rotation and bending strength.
-
Ideally within the first few weeks, before the tendon retracts and scars, which makes repair more difficult.
-
Most patients regain excellent bending and rotation strength after repair and a staged rehabilitation.
