Distal biceps tendon rupture

Distal biceps tendon rupture

Back to dictionary

In plain language

Partial or complete disruption of the tendon attaching biceps to the radial tuberosity, affecting supination and elbow-flexion strength.

01

Clinical Significance & Management

Complete tears generally do not reattach to their original footprint spontaneously. Repair is often considered for high functional demands; nonoperative care can suit lower demands or greater surgical risk, accepting weakness. Early assessment preserves options.

02

Symptoms & Clinical Presentation

1

Anterior elbow pop, bruising, swelling or changed contour

2

Weak supination and reduced lifting endurance

03

Etiology & Injury Mechanisms

  • Sudden forced extension against resistance
  • Smoking and certain drug exposures may increase risk
04

Diagnostics & Imaging Guide

Clinician assessment of continuity, Hook test and supination

Ultrasound or MRI for uncertain/partial tears; radiographs for bone injury

05

Treatment Options

Option 1

Protection and rehabilitation for selected partial tears

Option 2

Discuss repair for complete tears and risks such as nerve injury or stiffness

06

Rehabilitation Milestones & Timeline

Rehabilitation depends on the diagnosis, procedure and associated injuries. Progression requires assessment of healing, symptoms and function; elapsed time or a single test cannot determine readiness for sport.

Protection

Brace as directed; avoid resisted flexion and supination

Recovery

Progress motion before strengthening under clearance

Return

Assess strength, endurance and task loading; recovery commonly takes months

Red Flags & Urgent Warnings

Seek immediate emergency or specialist orthopaedic evaluation if any of the following occur:

New substantial supination weakness warrants prompt assessment

Cold, pale fingers or increasing numbness need urgent care

07

Evidence-Based Clarifications

Preserved flexion or reduced pain does not exclude complete rupture. Proximal and distal tears have different consequences.
