Being run over by a car, even partially, is a serious incident that can lead to a wide range of injuries, from minor abrasions to severe internal damage. The force exerted by a vehicle’s tire on the delicate structures of the foot can result in significant trauma. Knowing how to respond promptly can help mitigate the severity of the outcome.
Immediate Actions and First Aid
After a car runs over a foot, first move the injured person to a safe location, away from traffic or any ongoing danger. Assess for visible injuries, such as cuts, bruising, or deformities. If the shoe is causing pain or constricting the foot, carefully remove it, possibly by cutting if necessary to avoid further injury.
Elevating the injured foot on a pillow can help reduce swelling. Applying a cold pack gently to the affected area, with a cloth barrier, can also help. If there is bleeding, apply gentle, direct pressure. Stabilize the foot or ankle with a splint, then check for toe sensation and circulation. Regardless of how minor the injuries may seem, immediate professional medical evaluation is necessary.
Understanding Potential Injuries
The human foot is a complex structure containing 26 bones, 33 joints, over 100 soft tissues including muscles, tendons, and ligaments, and three major nerve branches. When a car runs over a foot, the immense pressure and force can cause a variety of injuries to these intricate components.
Bone fractures are common, with the metatarsals (long bones leading to the toes), phalanges (toe bones), calcaneus (heel bone), and other tarsal bones being particularly vulnerable. Fractures can be simple breaks or more severe, such as shattered bones. Crush injuries, where the foot is compressed under the vehicle’s full force, often involve multiple types of damage, including lacerations, bruising, swelling, and fractures. These severe traumas can also impair blood flow and nerve function.
Soft tissue damage frequently occurs, affecting muscles, tendons, and ligaments. Sprains involve the stretching or tearing of ligaments, which connect bones to other bones, while strains refer to damage to muscles or tendons, which connect muscle to bone. Bruising is also common from the impact. Deep lacerations can damage underlying tendons, muscles, and bones.
Nerve damage can result from the forceful impact. Symptoms may include tingling, numbness, sharp pain, or a complete loss of feeling in the foot. In some cases, a person may experience “foot drop,” where the foot drags while walking, indicating nerve impairment.
Vascular injuries can also occur, involving a tear or puncture causing blood loss, or damage from crushing or twisting. Impaired circulation due to vascular trauma or severe swelling, such as in compartment syndrome, can lead to muscle and nerve damage, and even limb loss if not addressed promptly.
Medical Assessment and Treatment
Upon arrival at a medical facility, healthcare professionals will conduct a thorough initial examination of the injured foot. This assessment helps determine the extent of the trauma and identifies any immediate concerns, such as active bleeding or severe deformity. Various imaging techniques are then employed.
X-rays are typically the first line of imaging to detect bone fractures and dislocations. For more complex injuries, such as severe crush injuries or midfoot injuries, a Computerized Tomography (CT) scan may be indicated. In cases where soft tissue damage, nerve injury, or vascular compromise is suspected, Magnetic Resonance Imaging (MRI) can provide detailed views of muscles, tendons, ligaments, and blood vessels.
Pain management is an immediate priority, often involving medication to alleviate discomfort. Wound care is also provided to prevent infection, particularly with lacerations or puncture wounds. Fractures may require immobilization with casts or boots, and in many instances, surgical intervention with plates and screws is necessary to realign and stabilize bones. Severe soft tissue damage or vascular injuries may also necessitate surgery to repair torn tissues, restore blood flow, or address compartment syndrome, a condition where swelling restricts circulation.
The Healing and Recovery Process
The healing and recovery from a foot run-over incident can be a lengthy process. Initial recovery often involves a period of immobilization, using casts, splints, or walking boots to protect the injured structures and promote healing. This phase typically lasts several weeks.
Once the initial immobilization period concludes, physical therapy and rehabilitation exercises become a central part of the recovery. These programs are designed to gradually regain strength, improve range of motion, and restore flexibility in the foot and ankle. Exercises might include gentle stretches, weight-bearing activities, and balance training. Swelling and pain management continue throughout recovery, often with elevation, ice, and pain relievers.
Long-term considerations can include persistent stiffness, chronic pain, or an altered gait. Some individuals may experience limited mobility or difficulty returning to previous activity levels. The overall goal of rehabilitation is to maximize functional recovery and minimize lasting impairments, but complete return to pre-injury function is not always possible in severe cases.
