A foot run over by a car can result in severe injuries due to the complex structure of the foot and the immense force involved. The extent of damage can range significantly based on factors like the vehicle’s weight, speed, and the precise point of impact. Such an event requires prompt attention to mitigate potential long-term complications.
Immediate Reactions and First Steps
Immediately following a foot being run over by a car, emergency services should be contacted without delay to ensure professional medical assistance arrives quickly. While waiting for help, it is important to assess the injured person’s condition. The foot should be elevated, ideally above heart level, to help reduce swelling. If there is bleeding, direct pressure should be applied with a clean cloth. Movement of the injured foot should be avoided to prevent further damage.
Common Injuries to the Foot
A foot run over by a car typically involves crush injuries, characterized by significant damage to multiple tissues due to compression. This type of trauma can lead to a combination of issues, including lacerations, bruising, swelling, and fractures.
Soft tissue damage is almost always present, encompassing bruising, abrasions, and deep lacerations. Muscles and tendons can experience tears or strains, while ligaments, which connect bones, may sprain or rupture. These injuries can cause significant pain and difficulty with movement.
Bone fractures are a common outcome, given the foot’s 26 bones. Fractures can occur in the metatarsals (midfoot), phalanges (toes), or tarsal bones like the calcaneus (heel bone) and talus. Crush injuries often lead to complex fractures, including comminuted fractures where the bone shatters, or Lisfranc fractures affecting the midfoot. Heel bone fractures, which can be debilitating, often require surgery.
Nerve damage can manifest as tingling, numbness, or a complete loss of sensation in the affected area. This can result from compression or tearing of the nerves, leading to sharp, burning, or shooting pain. If nerve damage is severe, it can cause muscle weakness or even paralysis.
Vascular damage, affecting blood vessels, is a serious concern. It can lead to significant swelling and compromise circulation, potentially resulting in compartment syndrome. Compartment syndrome occurs when pressure builds within the muscle compartments, restricting blood flow and potentially leading to permanent muscle and nerve damage if not treated promptly. Symptoms include severe pain, tightness, numbness, and a feeling of pins and needles. In some cases, damage to blood vessels may require surgical repair to restore blood flow and prevent tissue death.
Medical Assessment and Treatment
Upon arrival at a medical facility, a comprehensive evaluation begins with a detailed physical examination to assess for deformity, circulation issues, and neurological signs. Diagnostic imaging is crucial for understanding the extent of internal damage. X-rays are typically the first step to identify fractures. For more complex injuries, particularly those involving multiple bones or significant soft tissue damage, CT scans provide detailed cross-sectional images. An MRI may be used if soft tissue injuries, tendon ruptures, or compartment syndrome are suspected.
Non-surgical options are considered for less severe cases. These often involve RICE therapy—Rest, Ice, Compression, and Elevation—to manage pain and swelling. Immobilization using casts, splints, or walking boots helps stabilize fractured bones and allow for proper healing. Pain management typically includes prescribed medications.
Surgical intervention becomes necessary for complex fractures, significant nerve or vascular damage, or severe soft tissue injuries. Procedures may involve realigning and stabilizing bone fragments with pins or screws, repairing torn tendons or ligaments, or addressing damaged blood vessels to restore circulation. In cases of acute compartment syndrome, a fasciotomy, which involves cutting open the fascia to relieve pressure, is an urgent surgical procedure.
Recovery and Rehabilitation
Recovery from a foot run over by a car can be a prolonged process, often requiring several weeks to months for significant healing. The initial healing time for fractures, such as metatarsal bones, can range from 6 to 8 weeks, but full recovery may take longer. Long-term swelling and stiffness are common challenges.
Physical therapy plays a central role in restoring function and mobility. Rehabilitation programs include range of motion exercises to gently reintroduce movement, stretching to improve flexibility, and strengthening exercises to rebuild muscle strength. Gradually, weight-bearing exercises are introduced to encourage bone and tissue repair and prepare the foot for daily activities.
Occupational therapy might be recommended to help individuals adapt to any temporary or permanent limitations and regain independence in daily tasks. Depending on the severity of the initial trauma, potential long-term implications can include chronic pain, arthritis, or persistent functional limitations.
