Elbow & shoulder condition

Biceps & Triceps Tendon Injuries Treatment in Singapore

The biceps bends the elbow and turns the palm up; the triceps straightens it. Between them they anchor at three places — the biceps at the shoulder and again at the elbow, the triceps at the back of the elbow — and where a tendon gives way decides how urgently it needs attention. A biceps tear at the shoulder is common, causes surprisingly little weakness and often needs no surgery. A biceps tear at the elbow, or a complete triceps tear, is a different matter: both cause real loss of power and both do far better repaired early, because a torn tendon retracts and scars while you wait.

Is your injury one to act on quickly? Check the signs

Tap any that apply to you — this is guidance, not a diagnosis, but some of these mean time matters.

A sudden pop or tearing sensation while lifting or catching something heavy Bruising in the crease of the elbow, or across the back of the elbow The muscle looks bunched or misshapen compared with the other arm Marked weakness turning the palm upwards — screwdrivers, doorknobs, jar lids You cannot straighten the elbow against resistance — act quickly Gradual ache at the front or back of the elbow with loading, no sudden injury

Three tendons, three different urgencies

The same two muscles, but where the tendon fails changes everything that follows:

Biceps at the shoulder — common, rarely urgent — usually a worn tendon that finally gives way, sometimes with an audible snap. The muscle bunches downwards into the well-known bulge, but the other head of the biceps carries on working and measurable weakness is modest. Many are managed without surgery.
Biceps at the elbow — the time-sensitive one — the gym’s classic injury, typically from catching a heavy weight as the arm straightens. Bruising appears in the elbow crease and power turning the palm up drops sharply. Best repaired within weeks, before the tendon retracts.
Triceps at the back of the elbow — rare, and easily missed — the least common major tendon rupture there is, usually from a fall onto an outstretched hand or heavy pressing. A partial tear still allows straightening against gravity, which is exactly why it gets dismissed.
Tendinopathy rather than rupture — far commoner than either. Pain that builds with loading and never gives way, at the front of the elbow with the biceps or the back with the triceps, from repeated pressing, pulling or overhead work.
What makes a rupture more likely — middle age, heavy resistance training, smoking, and certain medical conditions that affect tendon quality.
What sits alongside it — a shoulder biceps problem frequently accompanies rotator cuff or labral tears, and is often addressed at the same time. More: SLAP tears →

Signs & symptoms of biceps & triceps injuries

A sudden pop or tearing sensation, often while lifting or catching a load
Bruising in the elbow crease, or across the back of the elbow
A bunched, misshapen muscle belly compared with the other arm
Loss of power turning the palm upwards with a distal biceps tear
Inability to straighten the elbow against resistance with a triceps tear
Cramping ache in the upper arm with activity
With tendinopathy, pain that builds gradually with loading and no give-way

What to do now — and what to stop doing

If a tendon gave way suddenly, treat it as time-sensitive until told otherwise. Rest the arm in a sling if that is comfortable, avoid lifting and loading it, and get it assessed within days rather than weeks — particularly if there is bruising at the elbow, weakness turning the palm up, or difficulty straightening against resistance. That urgency is not about pain, which often settles quickly and misleads people into waiting; it is about the tendon retracting and scarring, which makes a straightforward repair progressively harder. Do not test it repeatedly by loading the arm to see how bad it is. If instead the pain built gradually with no sudden give-way, this is tendinopathy, and the approach is the opposite of urgent: ease the loading that provoked it — pressing work for the triceps, pulling and curling for the biceps — then rebuild the tendon with a progressive strengthening programme rather than resting and waiting. And a bunched-up muscle at the shoulder with little weakness, while alarming to look at, is usually the least worrying version of all.

Biceps & triceps tendon injuries treatment, step by step

Treatment follows the site of the injury and whether the tendon gave way or simply became painful:

Establishing which tendon, and which end — examination testing power turning the palm up and straightening against resistance, with imaging where the picture is unclear or a repair is planned.
Non-surgical care for a shoulder biceps tear — settling the pain, restoring movement and strengthening, which suits many people well given the modest functional loss.
Prompt repair of a distal biceps rupture — reattaching the tendon to the bone, ideally within the first few weeks, to restore the power lost turning the palm upwards.
Repair of a complete triceps rupture — reattaching the tendon to the back of the elbow, again best done early, to restore the ability to straighten against load.
Graded loading for tendinopathy — adjusting what provoked it, then a progressive strengthening programme, which is the treatment with the best evidence for a painful but intact tendon. More: physiotherapy →
Rehabilitation after repair — a protected period, then staged movement and strengthening over months, since a reattached tendon heals to bone on its own timetable. More: biceps tendon repair →

Tendon injury myths, busted

Tap each card to reveal the truth:

Protecting these tendons

Build up heavy pulling and pressing volume gradually rather than in jumps
Take particular care with lowering phases, where ruptures usually happen
Avoid catching or arresting a falling load with a straightening arm
Warm the arm up properly before heavy lifting
Treat a painful tendon early rather than training through it for months
Get a sudden pop with bruising assessed within days, not weeks
Complete the rehabilitation after any repair before returning to loading

Biceps & triceps tendon injury FAQs

Where can the biceps and triceps tendons tear, and does it matter?

It matters more than almost anything else about these injuries, because the site decides the urgency. The biceps has an attachment at the shoulder and another at the elbow; the triceps attaches at the back of the elbow. A biceps tear at the shoulder is common, often causes surprisingly little weakness, and frequently needs no surgery at all. A biceps tear at the elbow is a different matter — it causes real loss of power and is best repaired promptly. A complete triceps tear is rare but likewise needs prompt repair. Same two muscles, three quite different situations.

Why is a distal biceps tear treated so urgently?

Because the torn tendon retracts up the arm and begins to scar, and the longer that goes on the harder the repair becomes. Fixed within the first few weeks it is usually a straightforward reattachment; left for months, the tendon may have shortened enough that a graft is needed to bridge the gap, with a more complex operation and a less predictable result. The functional stakes are real too: this tendon is the main power source for turning the palm upwards, so an unrepaired tear leaves a marked and permanent weakness with screwdrivers, doorknobs and jar lids.

Can I still use my arm if the tendon has torn?

Usually yes, and that is exactly why these injuries get missed. Other muscles bend the elbow, so a distal biceps rupture still allows you to lift your arm and bend it — what disappears is power turning the palm upwards. Similarly, a partial triceps tear often still permits straightening the elbow against gravity, so people assume the tendon is intact; the test that reveals it is straightening against resistance. Being able to move the arm is not evidence the tendon is whole, and treating it as such is what turns a repairable injury into a late one.

What is the bulge in my upper arm?

That is the classic sign of a biceps tendon rupture at the shoulder — the muscle belly, no longer tethered at its upper end, bunches downward towards the elbow and produces a prominent lump. It looks dramatic and is often what prompts people to seek advice, but at the shoulder it is largely a cosmetic change: the other head of the biceps continues to do the work, and measurable weakness is usually modest. Surgery is considered mainly for younger or heavily active people, for persistent cramping pain, or where the appearance genuinely bothers someone.

What about tendon pain without a sudden tear?

That is tendinopathy rather than rupture, and it is considerably more common. At the front of the elbow or shoulder it comes from repeated loading of the biceps; at the back of the elbow, triceps tendinopathy typically follows pressing work — bench press, dips, overhead lifting or trades involving repeated forceful straightening. The tendon becomes painful and loses capacity without giving way. It is treated in the same way as other troubled tendons: adjust the load that provoked it, then rebuild the tendon deliberately with a progressive strengthening programme rather than resting and hoping.
