Muscle injuries are a common occurrence in sports, with muscle strains being one of the most common reasons for missed playing time in professional sports. Muscle strains, also known as pulled muscles, occur when a muscle is overstretched or torn due to fatigue, overuse, or improper use. This results in pain and limited movement, with mild to moderate strains being treatable at home and severe strains requiring medical attention and sometimes even surgery. On the other hand, a fracture involves a cracked or broken bone, which may also damage the surrounding joints and ligaments. Fractures can be further classified into various types, such as closed, open, greenstick, comminuted, and avulsion fractures, each with its own unique characteristics and treatment considerations. Understanding the differences between muscle strains and fractures is crucial for proper diagnosis, treatment, and athlete care.

What You'll Learn

Muscle strain grades
Muscle strains, also known as pulled muscles, occur when a muscle is overstretched or torn. This is usually due to fatigue, overuse, or improper use of a muscle. They can happen in any muscle, but they are most common in the lower back, neck, shoulder, and hamstring.
Muscle strains are graded by severity:
- Grade I: A mild muscle strain involves a small amount of damage without a complete tear. Only a limited number of fibres in the muscle are affected, and there is no or minimal loss of strength. However, there may be some swelling and limited disability. It is recommended to avoid any physical activity that may worsen the injury. Grade I strains usually heal within a few weeks.
- Grade II: A moderate muscle strain involves a partial tear of the muscle, with some or most of the muscle fibres being affected. This will impact muscle strength and range of motion, and the healing process can take around 2-3 weeks. It is recommended to return to physical activity gradually after about a month.
- Grade III: A severe muscle strain involves a complete tear of the muscle fibres. This results in significant pain and very limited movement. Grade III strains may require surgery to repair the muscle and can take four to six months to heal.
It is important to note that most muscle strains can be successfully treated at home with rest, ice, compression, and elevation (RICE). Additionally, anti-inflammatory medications and pain relievers can be used to reduce pain and swelling. However, for severe strains, medical attention may be required, and physical therapy may be recommended.

Muscle tear causes
Muscle tears, also known as muscle strains or pulled muscles, are common but painful injuries. They occur when the muscle fibres are stretched beyond their limit and tear apart, causing a partial or complete tear of the muscle. This usually happens as a result of fatigue, overuse, improper use, or not warming up before exercise.
Muscle tears can happen in any muscle, but they are most common in the lower back, neck, shoulder, and hamstring. They are particularly common among athletes, especially in sports that require explosive movements, such as sprinting or cutting sports. The hamstrings, calf, quadriceps, and hip adductor muscles are the most susceptible to injury due to the muscle crossing two joints.
Acute muscle strains happen suddenly and cause immediate symptoms. They can be caused by a sudden, forceful movement, twisting, or jumping. They are often sports injuries but can also occur in everyday life. Chronic muscle strains, on the other hand, develop gradually, and symptoms worsen over time. They can be caused by repetitive movements, such as holding your back or neck in an awkward position for long periods.
The severity of a muscle tear can vary from mild to severe. A mild strain causes minor damage to the muscle fibres, but the muscle is not completely torn through. A moderate strain has torn through some or most of the muscle, affecting muscle strength and range of motion. A severe strain is when the muscle is completely torn through, resulting in severe pain and very limited movement. Severe tears may require medical treatment or even surgery.

Muscle strain treatment
Muscle strains, or pulled muscles, are common but painful injuries. They occur when a muscle is overstretched or torn, usually as a result of fatigue, overuse, or improper use. Strains can happen in any muscle, but they are most common in the lower back, neck, shoulder, and hamstring.
Most muscle strains can be treated at home, and the muscle will heal over time. For mild to moderate strains, rest, ice, compression, and elevation (RICE) are recommended. Anti-inflammatory medications and pain relievers can also help reduce pain and swelling.
If you have a severe strain, you may need medical attention and physical therapy. Surgery is rarely required, but may be necessary in very severe cases. To determine the extent of the injury, your doctor may use physical examination and imaging tests, such as X-rays and MRI scans.
During recovery, it is important to avoid activities that cause pain and may further injure the muscle. The muscle may retain some scar tissue, which is stiffer and more brittle than healthy muscle tissue, making it more susceptible to future tears. Therefore, you may need to be more mindful of how you use the muscle in the future.

Muscle strain prevention
Muscle strains, or pulled muscles, occur when a muscle is overstretched or torn. This can be caused by fatigue, overuse, improper use, or injury. Strains can happen in any muscle, but they are most common in the lower back, neck, shoulder, and hamstring.
To prevent muscle strains, it is important to warm up before engaging in physical activity. Warming up elevates your body temperature and boosts blood flow to your muscles, making them less likely to get stiff, sore, and torn. Dynamic stretches, which involve moving through a range of motion without holding the stretch, are a good way to warm up before a workout. It is also important to cool down after a workout by using static stretches that you hold at the point of tension for at least 10-20 seconds. This will help speed up the process of eliminating lactic acid from your body and allow your muscles to recover more quickly.
In addition to warming up and cooling down, varying the frequency, variety, and intensity of your workouts can help prevent muscle strains. This gives your muscles time to heal and recover. It is recommended to take at least one day off a week from exercise and to get plenty of sleep at night. Interval training, which involves interspersing high-intensity workouts with rest periods, is a good way to vary the intensity of your workouts.
Staying hydrated is also important for preventing muscle strains. When you are dehydrated, your muscles become tense and more prone to cramping and tearing. Drinking enough water energizes your muscles, improves performance, and reduces the risk of muscle tension and cramping.
Finally, learning proper form for exercises is essential for preventing muscle strains. This helps keep your workouts within safe physical limits and reduces your risk of injury.

Muscle strain diagnosis
Muscle strain, or a "pulled muscle", is a common injury that occurs when a muscle is overstretched, torn, or suddenly and unexpectedly tears. This usually happens due to fatigue, overuse, improper use, or trauma. Strains can happen in any muscle, but they are most common in the lower back, neck, shoulder, and hamstring.
Mild to moderate strains can be treated at home with ice, heat, and anti-inflammatory medications. Severe strains or tears may require medical treatment.
The diagnosis of a muscle strain is usually based on the patient's medical history and a physical examination. During a severe examination, the physician may be able to feel the defect where the muscle has completely torn. An X-ray may be used to rule out a fracture or dislocation as the cause of pain. However, pure muscle injuries cannot be seen on regular X-rays.
Magnetic resonance imaging (MRI) scans are recommended when radiologic evaluation is necessary for diagnosis. MRI scans can help see any tears or other damage to muscles, tendons, and ligaments. They use strong magnetic frequencies to create a detailed picture of the inside of the body.
Imaging tests are especially important in tricky injuries like strains, as they can help providers quickly diagnose the damage and prescribe a treatment plan.
