Dead Leg
What is a dead leg?
The quadriceps is a group of four muscles that form the large muscle mass at the front of the thigh. A dead leg — also known as a quadriceps contusion, cork thigh, corky, or quadriceps haemorrhage — occurs when there is damage to the quadriceps muscle along with internal bleeding. Physiotherapy is an effective treatment for managing a dead leg.
How does a dead leg happen?
A dead leg is caused by a direct impact to the thigh, typically from a collision with another person or being struck by an object. The force of the blow compresses the quadriceps muscle against the underlying bone, damaging the muscle fibres and blood vessels. This results in bleeding within the muscle and subsequent swelling.
What are the symptoms of a dead leg?
Pain is typically felt at the point of impact. In cases of a minor dead leg, it may be possible to continue participating in sport. However, as the muscle cools down after activity, the pain often increases due to ongoing bleeding and swelling. You may also notice a gradual tightening and stiffness in the quadriceps muscle. Other symptoms may include:
- Bruising around the site of the impact
- Swelling and tenderness in the thigh
- Difficulty bending or straightening the knee
- Limping or difficulty walking
- Muscle weakness or reduced strength in the thigh
What should I do if I have a dead leg?
You can support your recovery and reduce muscle tissue damage by following the RICE regime during the first 24–48 hours after injury. While swelling is part of the natural healing process, excessive swelling can delay recovery and lead to further tissue damage. The RICE protocol—Rest, Ice, Compression, and Elevation—is an effective way to manage swelling and minimise further injury.
Ice should be applied to the injured area for 15–20 minutes every 1–2 hours. Use a bag of frozen peas or crushed ice wrapped in a damp cloth to avoid skin irritation. Compression involves wrapping the thigh with an elastic bandage to help control swelling. The bandage should be firm but not so tight that it restricts circulation. Elevation means lying down with your leg supported on pillows or a chair so that it rests above the level of your heart, which helps reduce swelling. You should continue the RICE regime until you are assessed by a physiotherapist—ideally within the first 48 hours following the injury.
Physiotherapy treatment for a dead leg.
As you recover, your physiotherapist can provide a strengthening and stretching programme to accelerate your return to sports participation. They will also monitor your progress and gradually guide you through sport-specific exercises to ensure a safe and confident return to full activity. With proper diagnosis, treatment, and rehabilitation, most dead legs heal completely without long-term complications.
- Soft tissue massage to assist with the breakdown of scar tissue and improve circulation
- Electrotherapy such as ultrasound to promote tissue healing and reduce inflammation
- Stretching exercises to restore flexibility to the quadriceps muscle
- Strengthening exercises to rebuild muscle strength and prevent future injuries
- Range of motion exercises to maintain and restore normal joint movement
- Sport-specific rehabilitation to prepare for a safe return to training and competition
- Education and advice on activity modification, proper warm-up, and use of protective equipment
What shouldn’t I do if I have a dead leg?
In the first 48 hours after sustaining a dead leg, it is important to avoid activities that may increase blood flow to the quadriceps. Increased blood flow can lead to further bleeding into the muscle tissue, greater swelling, and increased pain, ultimately delaying recovery. Activities to avoid during this period include hot showers, stretching the quadriceps, applying heat rubs, massage, consuming alcohol, and engaging in excessive physical activity.
Are there any long-term effects from a dead leg?
A condition known as myositis ossificans can develop if a dead leg is aggravated and begins to bleed again during recovery. This potentially serious complication can arise if an individual returns to activity too early or receives overly vigorous massage or stretching of the quadriceps muscle. Myositis ossificans involves the abnormal formation of bone tissue within the muscle, which can significantly delay recovery and may require prolonged treatment.
