Can a pelvic crush fracture cause numbness in the legs?
Hello doctor, I suffered a crush fracture of the right pelvis due to a car accident.
After treatment, I underwent surgery where a plate was placed on the right side of the pelvis and screws were inserted on the posterior side.
After the surgery, I noticed that my foot had no sensation (but I could move it).
A month and a half later, I began experiencing frequent pain and a sensation of electric shocks.
When my foot is placed on the ground, it becomes completely red and swollen, but when I lie down with it elevated above my heart, it returns to normal.
What could be the issue?

When a fracture occurs, it is possible that nearby nerves may be compressed.
You can follow up with your attending physician to determine whether the issue is related to the fracture or if there is another problem with the nerves.
The redness and swelling in the foot are likely due to poor circulation in the lower extremities, and it will take time to gradually recover.

After experiencing a traumatic event such as a pelvic fracture, especially one that requires surgical intervention, it is not uncommon to encounter a range of symptoms, including numbness, pain, and swelling in the affected areas. Your situation, involving a crush injury to the pelvis and subsequent surgical fixation with plates and screws, can lead to several complications that may explain the symptoms you are experiencing.
Firstly, the numbness and tingling sensations you describe in your foot could be attributed to nerve compression or damage that may have occurred during the injury or as a result of the surgical procedure. The pelvic region is densely populated with nerves, and any trauma or surgical manipulation can potentially lead to neuropathic pain, which is often described as a "pins and needles" sensation or feeling like an electric shock. This type of pain can be quite distressing and may require specific management strategies.
The swelling in your foot, particularly when you place it on the ground, suggests that there may be issues with venous return or lymphatic drainage in the affected limb. After surgery, it is common for patients to experience edema (swelling) due to inflammation, immobilization, or changes in circulation. Elevating the leg, as you have noted, helps reduce this swelling by promoting venous return and reducing the hydrostatic pressure in the veins of the leg.
In terms of management, it is crucial to follow a comprehensive rehabilitation program that includes physical therapy. A physical therapist can guide you through exercises that promote mobility, strength, and flexibility while also addressing any issues related to nerve function and circulation. They may also employ modalities such as electrical stimulation to help alleviate pain and improve nerve function.
Pain management is another critical aspect of your recovery. Nonsteroidal anti-inflammatory drugs (NSAIDs) can be effective in reducing inflammation and pain. However, if you find that over-the-counter medications are insufficient, it may be worth discussing with your healthcare provider the possibility of prescription medications or alternative therapies, such as nerve blocks or physical modalities.
It is also essential to monitor your symptoms closely. If the numbness worsens, or if you experience significant changes in your ability to move your foot or leg, it is crucial to seek medical attention promptly. These could be signs of complications such as compartment syndrome, which is a medical emergency.
In summary, the numbness, pain, and swelling you are experiencing after your pelvic fracture surgery are likely related to nerve involvement and post-surgical edema. Engaging in a structured rehabilitation program, managing pain effectively, and monitoring your symptoms will be key to your recovery. If you have any concerns or if your symptoms persist or worsen, please do not hesitate to reach out to your healthcare provider for further evaluation and management.
