Quadriceps Contusion (cork thigh)

Quadriceps contusion or a “cork thigh”, as it is commonly known, is the result of a severe impact to the thigh which consequently compresses against the hard surface of the femur (thigh bone). This often causes deep rupture to the muscle tissue and haemorrhage occurs, which is followed by inflammation. Such an injury can also occur in other body regions such as the calf or upper arm; however these are less common than in the thigh region.
This injury is often experienced in contact sport such as Australian football and rugby, or sports such as cricket, hockey or lacrosse where a hard ball or object may strike the thigh of a player.
- Contact sports and sports that require quick starts, ie. Running races and other track events.
- Warm up and cool down habits.
- Off season/preseason/season training habits.
- Poor muscle conditioning.
- Playing position.
- Level of competition.
- Protective equipment use.
- Playing experience.
- Injury history, especially to the thigh, hip and/or knee.
- Medical history of any bleeding disorder.
- Poor nutrition.
- Smoking history.
- Wearing protective padding over the thigh.
- Participating in a strengthening, flexibility and conditioning program appropriate for the sport being undertaken.
- Undertaking training prior to competition to ensure readiness to play.
- Gradually increasing the intensity and duration of training.
- Allowing adequate recovery time between workouts or training sessions.
- Checking the sporting environment for hazards.
- Drinking water before, during and after play.
- Avoiding activities that cause pain. If pain does occur, discontinuing the activity immediately and commencing RICER.
Signs and symptoms
At the time of this type of trauma a player may experience varying levels of pain and reduced range of motion. The extent of pain and loss of movement will be dependent on the amount of force and the impact of the force at the time of trauma. The traumatised area will become swollen and painful to touch.
Contusions are classified according to their severity.
The return to sport period form all grades of contusion injury may be significantly reduced with good early injury management practices and assessment by a sports medicine professional.
The more severe a contusion, the greater the risk of the development of myositis ossificans. In this condition calcification occurs in the healing haematoma. The healing haematoma forms small bone within layers of the affected muscle. Symptoms include overnight and morning pain, as well as pain on muscle contraction. It may be possible to feel a hard bump or ‘woody’ feel within the muscle. Stiffness and loss of knee range of movement are also common. Poor treatment of a contusion may also lead to the development of myositis ossificans.
Bone formation associated with myositis ossificans usually ceases after six to seven weeks, at which time the formed bone begins to break down and be reabsorbed by the body. Complete recovery can however take up to 12 months in more severe cases. Little can be done to accelerate the reabsorption process of myositis ossificans and care should be taken in the treatment of the condition to avoid its long term effects. Assessment by an experienced sports medicine professional may help with pain control and assist the recovery process with supervision of the rehabilitation process.
The immediate treatment of any soft tissue injury consists of the RICER protocol – rest, ice, compression, elevation and referral. RICE protocol should be followed for 48 to 72 hours. The aim is to reduce the bleeding and damage in the muscle. The thigh should be rested in an elevated position with an ice pack applied for 20 minutes every two hours (never apply ice directly to the skin). A compression bandage should be applied to limit swelling and bleeding in the injured area.
The NO HARM protocol should also be applied – no heat, no alcohol, no running or activity and no massage. This will ensure decreased swelling and bleeding in the injured area. Gentle, gradual, pain free stretching of the muscle will assist in restoring full range of motion in mild muscle contusion injuries. Moderate to severe contusions may require the use of crutches to ensure complete rest, particularly if full weight bearing on the affected leg is painful.
Rehabilitation and return to play
Light stretching should be utilized immediately post injury. This will help reduce muscle spasms and make stretching more beneficial in the days to come. Utilize standard quadriceps stretching techniques with the hip flexed and extended. These should be performed with a 10 second hold of the stretch, repeated three to five times daily.
Another early rehabilitation technique used is Quad Sets. These are isometric contractions of the muscle. The athlete tries to make the muscle flex and holds for 10 seconds, repeating 30 to 60 times, three to five times daily.
Strengthening of the injured muscle should begin two to seven days post-injury, depending upon the severity.
These exercises include:
- Four plain straight leg raises.
- Seated hip flexion.
- Seated knee extension.
- Partial squats.
- Side step-ups.
