Differential Diagnosis for Hamstring Injury
- Single most likely diagnosis
- Hamstring strain: This is the most common cause of hamstring injury, typically occurring during sprinting or other high-speed activities. It is characterized by a sudden onset of pain and swelling in the posterior thigh.
- Other Likely diagnoses
- Hamstring tendinopathy: This condition involves chronic inflammation of the hamstring tendons, often caused by repetitive strain or overuse. It presents with gradual onset of pain and stiffness in the posterior thigh.
- Hamstring contusion: A direct blow to the posterior thigh can cause a hamstring contusion, leading to pain, swelling, and bruising.
- Proximal hamstring avulsion: This injury occurs when the hamstring tendons are pulled off the bone, often resulting in severe pain and limited mobility.
- Do Not Miss diagnoses
- Compartment syndrome: Although rare, compartment syndrome is a potentially life-threatening condition that can occur after a hamstring injury. It is characterized by severe pain, swelling, and numbness in the affected limb.
- Vascular injury: A hamstring injury can occasionally be associated with damage to the nearby blood vessels, which can lead to serious complications if left untreated.
- Rare diagnoses
- Hamstring rupture: A complete tear of the hamstring muscles or tendons is a rare but serious injury that requires prompt medical attention.
- Popliteal artery entrapment syndrome: This rare condition involves compression of the popliteal artery, which can cause pain, numbness, and weakness in the affected limb.
- Peripheral nerve injury: Direct trauma or compression of the nearby nerves can cause numbness, tingling, or weakness in the affected limb.
