Distal biceps rupture
What is Distal biceps rupture?
A distal biceps rupture is a tear of the biceps tendon where it attaches near the elbow. It usually occurs when a flexed elbow is forced straight against resistance, such as catching a heavy object or lifting unexpectedly.
Common symptoms
Patients often feel a sudden pop, followed by bruising, swelling, pain at the front of the elbow and weakness with forearm rotation, especially turning the palm upwards. The biceps muscle may sit higher than normal.
Diagnosis and imaging
Clinical examination includes the hook test, assessment of tendon contour and strength testing. Ultrasound or MRI confirms the diagnosis, defines partial versus complete rupture and helps assess retraction.
Non-surgical treatment
Non-surgical care may be reasonable for partial tears, lower-demand patients or those comfortable accepting some loss of strength. It involves protection, gradual motion and strengthening once pain settles.
Surgical treatment
Surgical repair is usually recommended for active patients with complete rupture because it best restores supination and flexion strength. Early repair is generally preferred before tendon retraction and scarring make surgery more difficult.
Recovery and follow-up
After repair, the elbow is protected while the tendon heals. Motion is restored gradually, then strengthening progresses over months. Heavy lifting is delayed until healing and strength recovery are secure.
Distal biceps rupture FAQs
What strength is lost with a distal biceps rupture?
The largest loss is usually supination strength, which is the power to turn the palm upwards. Flexion strength can also be reduced.
How is distal biceps rupture diagnosed?
Diagnosis starts with a focused history and examination, then uses imaging selectively to confirm the pattern of injury, exclude related problems and plan treatment accurately.
Is distal biceps repair urgent?
It is not usually a same-day emergency, but early specialist assessment is important because delayed repair can become more complex.
Will I need surgery for distal biceps rupture?
Many patients improve without surgery. Surgery is considered when symptoms remain limiting despite appropriate non-surgical care, when there is significant structural damage, or when delay may compromise function.
When can I return to lifting and gym training?
Return depends on the diagnosis, treatment type, tissue healing and the physical demands of the activity. The plan is usually staged, with strength, range of motion and confidence rebuilt before unrestricted loading.
