What it is

Tendon repair surgery reattaches a torn distal biceps or triceps tendon to its bony anchor. A rupture occurs when a sudden load is applied, causing a loss of strength for pulling or pressing. Repair restores the lever arm, making daily tasks and sports feel reliable again.

Rehabilitation protects the repair early, restores range in safe arcs, and then rebuilds strength and power.

What happens when it occurs

Anchors and sutures secure the tendon to the bone. The early plan limits elbow and forearm loading that would stress the repair. Motion returns in stages, and strength is rebuilt with clear rules for range and grip.

Common causes and risk factors

  • A sudden load during a heavy lift or catch
  • Use of anabolic steroids or fluoroquinolone antibiotics
  • Smoking and metabolic health factors
  • Previous elbow or shoulder problems

Who is most affected

Middle-aged adults. Men present more often for distal biceps rupture. Triceps rupture typically occurs in strength athletes and following falls.

Typical symptoms before surgery

  • A pop with immediate weakness
  • Bruising and swelling at the front of the biceps or back of the triceps
  • Loss of supination strength for the biceps or loss of press strength for the triceps

When to seek care

Immediately after a suspected rupture. Timely repair improves outcomes.

How we diagnose

History, hook test for biceps, resisted extension for triceps, and ultrasound or MRI to confirm the tear and plan fixation.

Management

  • Protection with a brace or sling and clear load limits
  • Swelling control and wound care
  • Range in safe arcs set by the surgeon and therapist
  • Strength for the shoulder and scapula to share the load
  • Progressive elbow and forearm strength with set targets for return

Rehabilitation milestones

Phase 1 weeks 0 to 2: protection, hand and shoulder activity, passive and assisted range in the brace.

Phase 2 weeks 2 to 6: increase range by protocol, light isometrics in safe positions.

Phase 3 weeks 6 to 12: active range, progressive resistance for flexion, extension, and supination or pressing.

Phase 4 months 3 to 6: work and sport drills, power and endurance, criteria-based return.

Readiness to progress

  • Healing confirmed and pain stable
  • Range goals met without lag or shrug
  • Strength within 80 to 90 per cent, then task-specific testing

Long-term care

  • Build pulling and pressing capacity over months
  • Plan workload increases in steps
  • Maintain shoulder, trunk, and grip strength

Australia snapshot

  • Distal biceps repair is a regular procedure in public and private hospitals.
  • Men present more often than women for biceps rupture
  • Day surgery pathways and structured rehabilitation are widely available

Latest insights

Protection first, then progressive load. Supination and press strength return when the chain above and below the elbow is trained.

Grip choice and range control protect the repair during the early strengthening phase.

Frequently Asked Questions

Often, within the first few weeks after injury. An earlier repair can be simpler.

Light loads begin after healing and range goals are met. Heavier work returns after strength testing.

A contour change may remain after a biceps rupture. Function is the goal and usually recovers well.

Once the brace allows safe control, you can react comfortably. Confirm with your team and insurer.
