Hamstring Muscle Injuries Specialist
Hamstring injuries are extremely common among athletes and can be the result of a pull, partial tear, or a complete tear of your hamstring muscles. If you sustain this injury, you may experience a sharp pain immediately upon injury, followed by swelling, bruising or discoloration in the back of your leg, or weakness in your hamstring. Hamstring strains are graded according to their severity. Grade 1 strains are mild and able to heal at a rapid pace, while grade 3 strains are complete tears of the muscle that require months to fully heal. The severity of your condition will determine the treatment you receive.
At Barrington Orthopedic Specialists, our highly-trained, certified sports medicine specialists will assess the condition of your torn hamstring with a physical examination and imaging tests. Following an evaluation of your injury, an orthopedist will provide you with treatment options. While most hamstring tears can heal with nonsurgical treatment such as rest, immobilization, and physical therapy, surgical options may be considered if the tear has caused the tendon to pull away from the bone completely. Our team will work with you to discuss your treatment options to ensure your optimal recovery.
If you have sustained a hamstring tear, we are here to help. Schedule your first consultation with the team at Barrington Orthopedic Specialists today. If you’re in an emergency situation, visit the Immediate Care Clinic at our Schaumburg, IL location.
Hamstring Muscle Injuries FAQ
What Are Hamstring Muscle Injuries?
A hamstring injury can be a pull, a partial tear, or a complete tear of one of your hamstring muscles ~the group of three muscles that run along the back of your thigh.
Muscle strains are graded according to their severity. A grade 1 strain is mild and usually heals readily; a grade 3 strain is a complete tear of the muscle that may take months to heal.
Most hamstring injuries occur in the thick part of the muscle or where the muscle fibers join tendon fibers.
In the most severe hamstring injuries, the tendon tears completely away from the bone. It may even pull a piece of bone away with it. This is called an avulsion injury.
You may be more likely to get a hamstring injury if you play soccer, basketball, football, tennis or a similar sport that involves sprinting with sudden stops and starts.
What Causes Hamstring Muscle Injuries?
Muscle overload is the main cause of hamstring muscle strain. This can happen when the muscle is stretched beyond its capacity or challenged with a sudden load.
Hamstring muscle strains often occur when the muscle lengthens as it contracts, or shortens. Although it sounds contradictory, this happens when you extend a muscle while it is weighted, or loaded. This is called an “eccentric contraction.”
During sprinting, the hamstring muscles contract eccentrically as the back leg is straightened and the toes are used to push off and move forward. The hamstring muscles are not only lengthened at this point in the stride, but they are also loaded — with body weight as well as the force required for forward motion.
Like strains, hamstring tendon avulsions are also caused by large, sudden loads.
Several factors can make it more likely you will have a muscle strain, including:
Muscle tightness. Tight muscles are vulnerable to strain. Athletes should follow a year-round program of daily stretching exercises.
Muscle imbalance. When one muscle group is much stronger than its opposing muscle group, the imbalance can lead to a strain. This frequently happens with the hamstring muscles. The quadriceps muscles at the front of the thigh are usually more powerful. During high-speed activities, the hamstring may become fatigued faster than the quadriceps. This fatigue can lead to a strain.
Poor conditioning. If your muscles are weak, they are less able to cope with the stress of exercise and are more likely to be injured.
Muscle fatigue. Fatigue reduces the energy-absorbing capabilities of muscle, making them more susceptible to injury.
Choice of activity. Anyone can experience hamstring strain, but those especially at risk are:
- Athletes who participate in sports like football, soccer, basketball
- Runners or sprinters
- Older athletes whose exercise program is primarily walking
- Adolescent athletes who are still growing. Hamstring strains occur more often in adolescents because bones and muscles do not grow at the same rate. During a growth spurt, a child’s bones may grow faster than the muscles. The growing bone pulls the muscle tight. A sudden jump, stretch, or impact can tear the muscle away from its connection to the bone
What Are The Symptoms of Hamstring Muscle Injuries?
If you strain your hamstring while sprinting in full stride, you will notice a sudden, sharp pain in the back of your thigh. It will cause you to come to a quick stop, and either hop on your good leg or fall.
Additional symptoms may include:
- Swelling during the first few hours after injury
- Bruising or discoloration of the back of your leg below the knee over the first few days
- Weakness in your hamstring that can persist for weeks
Patient History and Physical Examination
People with hamstring strains often see a doctor because of a sudden pain in the back of the thigh that occurred when exercising.
During the physical examination, your doctor will ask about the injury and check your thigh for tenderness or bruising. He or she will palpate, or press, the back of your thigh to see if there is pain, weakness, swelling, or a more severe muscle injury.
Imaging tests that may help your doctor confirm your diagnosis include:
X-rays. An X-ray can show your doctor whether you have a hamstring tendon avulsion. This is when the injured tendon has pulled away a small piece of bone.
Magnetic Resonance Imaging (MRI). This study can create better images of soft tissues like the hamstring muscles. It can help your doctor determine the degree of your injury.
What Are The Treatment Options For Hamstring Muscle Injuries?
Treatment of hamstring strains will vary depending on the type of injury you have, its severity, and your own needs and expectations.
The goal of any treatment — nonsurgical or surgical — is to help you return to all the activities you enjoy. Following your doctor’s treatment plan will restore your abilities faster, and help you prevent further problems in the future.
Most hamstring strains heal very well with simple, nonsurgical treatment.
RICE. The RICE protocol is effective for most sports-related injuries. RICE stands for Rest, Ice, Compression, and Elevation.
Rest. Take a break from the activity that caused the strain. Your doctor may recommend that you use crutches to avoid putting weight on your leg.
Ice. Use cold packs for 20 minutes at a time, several times a day. Do not apply ice directly to the skin.
Compression. To prevent additional swelling and blood loss, wear an elastic compression bandage.
Elevation. To reduce swelling, recline and put your leg up higher than your heart while resting.
Immobilization. Your doctor may recommend you wear a knee splint for a brief time. This will keep your leg in a neutral position to help it heal.
Physical therapy. Once the initial pain and swelling has settled down, physical therapy can begin. Specific exercises can restore range of motion and strength.
A therapy program focuses first on flexibility. Gentle stretches will improve your range of motion. As healing progresses, strengthening exercises will gradually be added to your program. Your doctor will discuss with you when it is safe to return to sports activity.
Surgery is most often performed for tendon avulsion injuries, where the tendon has pulled completely away from the bone. Tears from the pelvis (proximal tendon avulsions) are more common than tears from the shinbone (distal tendon avulsions).
Surgery may also be needed to repair a complete tear within the muscle.
Procedure. To repair a tendon avulsion, your surgeon must pull the hamstring muscle back into place and remove any scar tissue. Then the tendon is reattached to the bone using large stitches or staples.
A complete tear within the muscle is sewn back together using stitches.
