A thigh contusion is also known as a dead leg or charley horse and is caused by direct trauma to the muscle. Here we explain the treatment of mild, moderate and severe contusions.
Symptoms of a thigh contusion
- Pain at the time of injury.
- Restricted movement and inability to run properly. If your contusion is severe, even walking may be difficult.
- Swelling may develop quickly, and later bruising may or may not appear depending on the type of injury sustained.
How bad is my thigh contusion?
Thigh contusions can range in severity from very mild which is hardly noticeable at the time to severe disabling injuries where the athlete is unable to walk. Like muscle strains, contusions are grade 1, 2 or 3 depending on how bad they are.[the_ad id=”41081″]
If you have a grade 1 thigh contusion will feel tightness in your thigh. You may walk with a limp. However, you are unlikely to have much swelling. Trying to straighten your knee against resistance probably won’t produce much pain and you will still have nearly a full range of motion when stretching.
With a grade 2 you are unlikely to be able to walk properly. You will have occasional sudden twinges of pain during activity. You may have swelling and trying to straighten your knee against resistance will be painful. Pressing in (palpating) over the site of injury will be painful.
Although a dead leg or charlie horse can often seem a minor injury, it is important the correct diagnosis is made as failure to treat them properly can lead to long-term injury or permanent damage to the muscle.
Grade 3 contusions mean you will be unable to walk without the aid of crutches. You will be in severe pain and significant swelling will appear immediately. Contracting the muscle may produce a visible bulge or gap in your thigh. Expect to be out of competition for 3 to 12 weeks.
Thigh contusion causes & anatomy
Skeletal muscles are made up of bundles of muscle fibres. The muscle is surrounded by a protective sheath called the Epimysium. A thigh contusion is caused by a direct impact or trauma to the muscle which crushes it against the bone underneath, causing internal bleeding in the muscle. Contusions are either intramuscular or intermuscular depending on whether the bleeding is contained within the muscle sheath, or whether the sheath is also damaged and the muscle bleeds outside the muscle sheath.
Intramuscular hematoma is a tearing of the muscle within the sheath that surrounds it. This means that the initial bleeding may stop early within hours because of increased pressure within the muscle, however, the fluid is unable to escape as the muscle sheath prevents it. The result is considerable loss of function and pain, which can take days or weeks to recover. You are not likely to see any bruising come out with this type – especially in the early stages.
Intermuscular hematoma is a tearing of the muscle and part of the sheath surrounding it. This means that the initial bleeding will take longer to stop, especially if you do not ice it. However, recovery is often faster than intramuscular as the blood and fluids can flow away from the site of injury. You are more likely to see bruising come out with this one.
If after two to three days the swelling has not gone, then it is probably an intramuscular injury. This means any bleeding contained within the muscle. If the bleeding has spread and caused bruising away from the site of the injury then it is probably an intermuscular injury. You will have greater movement and muscle function if you injury is intermuscular.
If heat or massage is applied too early Myositis Ossificans or bone forming within the muscle.
Treatment for thigh contusions
We recommend seeking professional advice before starting any rehabilitation program. The aim of rehabilitation of a thigh contusion is to control the initial pain and swelling, maintain and improve flexibility, restore muscle strength and gradually return to full fitness.
Reducing pain and swelling
- Regardless of how bad the injury is the PRICE principles of protection, rest, ice, compression and elevation should be applied as soon as possible.
- Apply a cold therapy and compression wrap immediately. Ice can be applied every two hours for 10 minutes for the first 72 hours for more severe contusions. This will help stop any internal bleeding and reduce pain and swelling.
- Wear a compression bandage or thigh support to protect the injury and help reduce swelling. Elevating the limb allows swelling and tissue fluids to drain away from the area.
It is very important to apply cold and compression to a contusion. Applying heat or deep massage in the acute stage may cause further injury or lead to myositis ossificans which is a bony growth within the muscle.
- Gentle stretching if it is not painful – hold for 30 secs, repeat 5 times daily. This may be started after the initial acute stage – usually 48 hours.
- From day four (no earlier – and it may be longer in severe injuries) apply heat (hot water bottle, hot baths, see a professional therapist for ultrasound).
A professional therapist can apply sports massage techniques to speed up recovery but ONLY once the acute phase has definitely passed. Heat treatment and massage can cause serious muscle damage if performed on an acute
Use of ultrasound and electrical stimulation may also be beneficial. Although the athlete is likely to be back to normal training within a few days for a grade 1 or mild quadriceps contusion, it is a good idea to develop stretching and strengthening exercises to ensure there is no long-term effect on performance.
Restoring muscle strength
For a grade one contusion, strengthening exercises may be performed as soon as they can be done without pain. Start with the easier exercises on a daily basis and progress as soon as you feel comfortable onto the more difficult exercises which should be done three times a week.
With a grade two contusion, it may be a week before strengthening is possible and a grade three even longer. All strengthening sessions should start with a gentle warm up and stretch and finish with a good stretch. Strengthening should continue for weeks after you feel the injury has healed.
If the athlete is unable to continue with normal training, then swimming or cycling can be done instead, or if this is not possible work on the upper body strength. It is important to continue a training routine of some description.
Returning to full fitness
This is a gradual process. For a grade one contusion normal training may be resumed with a few days. It is important to maintain a stretching and strengthening program alongside training to ensure full strengthening and mobility of the muscle.
Gentle jogging may be started and built up until the athlete can run comfortably for 40 minutes. Speedwork should be introduced gradually, for example: 10 x 60m at 50% of top speed, next session might be 10 x 60m at 70% top speed and so on.
Example rehabilitation program
Below are examples of how the above fit into a rehabilitation program for a grade 1,2 and 3 contusion.
- Rest, Ice, Compress and Elevate (R.I.C.E.) immediately. Use a compression bandage or heat retainer until no pain is felt.
- Gentle quadriceps stretching – hold for 30 secs, repeat 5 times daily.
- Leg extension exercises – 4 sets of 10 repetitions 3 times a week.
- Gradually build up the weight to strengthen the quads.
- Ease down your training for a week or two but no need to stop unless there is
- Ice, compress, elevate, use crutches for 3 to 5 days.
- From day three, pain-free static quadriceps exercises (contract quads and hold for 10 secs in the sitting position).
- Improve mobility by bending and straightening the leg (as long as it is not painful).
- Apply heat (hot water bottle, hot baths, see a specialist for ultrasound).
- When pain allows
dostraight leg raises (4 sets of 10 reps 3 times a week)
- From day 7 do leg extensions (4 sets of 10 reps three times a week).
- Swimming 2 to 3 times a week.
- Cycling 2 to 3 times a week.
- Begin stretching (hold stretches for 30 secs, 5 times a day).
- From day 14 start to jog and slowly get back into your sports activities.
- Week 1: You should seek medical attention immediately. R.I.C.E. (Rest, Ice, Compress, Elevate.) Use crutches.
- Week 2: Pain-free static contractions ( if it hurts don’t do it). Heat with a
hotwater bottle, hot bath or ultrasound. Straight leg raises if pain allows. Use no weight and do 4 sets of 10 reps every day.
- Week 3: All of the above plus straight
legraises with weights. 4 sets of 10 reps 3 times a week.
- Week 4: Pain-free leg extension exercises, 4 sets of 10 reps 3 times a week. Swimming 2 or 3 times a week. Cycling 2 or 3 times a week. Start stretching exercises, hold for 30 secs, 5 times a day.
- Week 5: Start jogging. Start squats, 4 sets of 6 to 8 reps 2 days a week. Gradually build up to sports specific exercises.
Although a contusion may not appear to be a serious injury, the effects can be long lasting if rehabilitation is not taken seriously.
Exercises for thigh contusions
Once the initial acute phase has passed, rehabilitation exercises are similar to those of a thigh strain.
Gentle quadriceps stretching exercises should begin as soon as pain allows after the first 24 hours. The emphasis should be on rest and healing rather than attempting to exercise too soon. However, once exercises can safely be done pain-free it is important to restore the muscle to its full mobility and strength. Strengthening exercises should only be done well after the acute stage.
Static stretches should be done very gently to begin with where the stretch is held for a period of time. Later more advanced pnf type stretches can be done if there is a noticeable lack of flexibility in the muscle.
