Sprain vs. Fracture: What’s the difference?

Sprain vs. Fracture: What’s the difference?

In the realm of orthopedic injuries, two terms often cause confusion: sprain and fracture. Understanding the differences between these two conditions is crucial for proper diagnosis and timely treatment. This article aims to shed light on the disparities between sprains and fractures, providing you with a comprehensive understanding of each.

What is a Sprain?

A sprain occurs when the ligaments, which connect bones to one another, are stretched or torn. Ligaments play a crucial role in stabilizing joints, and injury to these tough bands can result from sudden twists, falls, or impacts that force a joint beyond its normal range of motion.

Sprain Symptoms


  • Location: The pain is typically localized at the site of the injured ligament.

  • Intensity: The degree of pain can vary based on the severity of the sprain.


  • Inflammation: Sprains often cause swelling due to inflammation in the affected area.

  • Visible Changes: The swelling might result in a noticeable increase in the size of the joint.

Restricted Movement

  • Difficulty Moving: A sprain can lead to difficulty moving the joint normally.

  • Stiffness: The affected joint may feel stiff, limiting its range of motion.


  • Discoloration: Bruising or discoloration may develop around the injured area.

  • Appearance: The skin might turn red, blue, or purple, indicating blood vessel damage.

Warmth and Tenderness

  • Increased Temperature: The affected area might feel warmer than the surrounding tissue.

  • Tenderness to Touch: Touching the injured ligament can cause pain and tenderness.


  • Feeling Unsteady: Individuals with a sprain may feel a sense of instability in the affected joint.

  • Weakness: The injured area may feel weaker than usual.

Hearing or Feeling a Pop

  • Audible Pop: In some cases, a sprain may be accompanied by an audible pop at the time of injury.

  • Sensation of a Pop: Individuals might feel a sensation of popping or tearing.
