Strain vs. Rupture — What’s the Difference?

Both terms get used loosely, but they describe different levels of injury:

• Strain (mild to moderate): The tendon is stretched too far or has tiny tears. Painful and limiting, but the tendon is still intact.
• Partial rupture: Some fibers of the tendon are torn but the tendon isn’t completely separated.
• Complete rupture: The tendon has fully torn — sometimes pulled off the bone. This is the dramatic one, and it usually needs prompt attention.

Knowing which you’re dealing with is key — that’s where a specialist comes in.

What Tendon Injuries Feel Like

Symptoms vary depending on which tendon is involved and how badly it’s injured.

For strains, you might notice:

• A dull ache or sharp pain during activity
• Tenderness when you press on the area
• Weakness or loss of full strength
• Stiffness, especially in the morning or after rest

For ruptures (especially complete ones), it’s often more dramatic:

• A sudden “pop” or snap at the time of injury
• Immediate sharp pain
• Significant weakness — you may not be able to lift or push normally
• Visible bruising or swelling
• A bulge or deformity (like the classic “Popeye muscle” with a bicep tendon rupture)
• Pulling sensation in the affected arm

If you felt a pop or experienced sudden weakness, don’t wait — get evaluated. Tendon ruptures often need treatment within a specific window for the best outcome. Schedule a visit or come to our Urgent Care.

Common Tendon Injuries We See

Some of the most common tendon issues in the elbow, wrist, and hand include:

• Distal biceps tendon rupture — at the elbow, often from lifting something heavy with the arm bent
• Triceps tendon rupture — at the back of the elbow, less common but serious
• Forearm and wrist tendon strains — from overuse, repetitive motion
• Hand and finger tendon injuries — from cuts, crush injuries, or sports

The right approach depends entirely on which tendon and how badly it’s hurt.

What Happens at Your Visit?

Tendon injuries can look minor on the surface and be major underneath (or the reverse). When you come in, our specialists will:

• Listen to the story of how the injury happened
• Carefully examine for swelling, deformity, and weakness
• Test specific movements that target each tendon
• Use imaging (often ultrasound or MRI) when needed to see exactly what’s torn
• Talk you through your options based on what we find

Time matters with complete ruptures — the longer they go untreated, the more challenging the repair becomes. Don’t sit on a suspected rupture.

What Treatment Generally Looks Like

For strains and partial tears:

• Rest, ice, and activity modification
• Anti-inflammatory medication if appropriate
• A brace or splint to take pressure off the tendon
• Guided physical therapy to restore strength and function

For complete ruptures, surgical repair is often recommended — especially for active patients or younger adults. Your specialist will walk you through whether surgery is the right call for your specific case.
