How to assess the severity of a fracture and the healing time for fractures?


Hello Dr.
Chen: I was involved in a car accident on January 17, 2019, resulting in a comminuted fracture of my thigh, a comminuted and open fracture of my lower leg, and a torn posterior cruciate ligament in my knee.
I underwent surgery on January 18, 2019, where they realigned the bones and inserted steel plates and screws.
It has now been two months and three days since the surgery.
The doctor mentioned that because I am still young, I will recover quickly, but I am worried about the possibility of my bones not healing or healing slowly.

1.
How long will it take for me to be able to use crutches to walk given my condition?
2.
How can I assess the severity of my fractures?
3.
Is there a critical period for rehabilitation?
4.
I had my leg straightened and immobilized for a month, and now I can slowly start bending my knee.
Does this mean my ligaments have healed?
Thank you, doctor.

Hello, it seems that you have sustained a severe injury with a comminuted fracture of the femur and an open fracture of the tibia, along with a torn posterior cruciate ligament.
Comminuted fractures are generally worse than simple linear fractures, and open fractures are more serious than closed fractures, as open fractures have a higher risk of infection, which can lead to osteomyelitis.
The joint surface is worse than mid-shaft fractures.
The torn posterior cruciate ligament should be reconstructed; otherwise, it may lead to instability in the future, making it difficult to engage in sports.
It is best to consult your attending physician for the actual situation.
Thank you.

Understanding the severity of fractures and the healing time after an injury is crucial for recovery, especially after significant trauma such as a car accident. In your case, you have experienced multiple severe injuries, including comminuted fractures of the femur and tibia, as well as an open fracture and a torn anterior cruciate ligament (ACL). Here’s a detailed response to your questions based on medical knowledge and practices.

1. Timeframe for Using Crutches: The time it takes for you to be able to walk with crutches after such severe fractures can vary significantly based on several factors, including the type of fractures, the surgical intervention, and your overall health. Generally, after surgery, patients may begin partial weight-bearing as soon as the surgeon deems it safe, which could be anywhere from a few days to a few weeks post-surgery. Full weight-bearing might take longer, typically around 6 to 12 weeks, depending on the healing process and the stability of the fractures. Your orthopedic surgeon will monitor your progress through follow-up appointments and imaging studies to determine when you can safely transition from crutches to walking unaided.

2. Assessing Fracture Severity: The severity of a fracture can be assessed through various means. Clinically, the type of fracture (e.g., comminuted, open, closed) provides an initial indication of severity. Imaging studies, such as X-rays or CT scans, are essential for visualizing the fracture and assessing its complexity. Additionally, factors such as the presence of associated injuries (e.g., ligament tears, vascular or nerve injuries) and the patient’s overall health (age, bone density, etc.) also play a significant role in determining the severity. Your healthcare provider will use these assessments to guide treatment and rehabilitation plans.

3. Golden Period for Rehabilitation: Rehabilitation indeed has a "golden period," which refers to the optimal time frame for initiating physical therapy and rehabilitation exercises to promote healing and regain function. This period typically begins shortly after surgery and can last for several weeks. Early mobilization and physical therapy can help prevent stiffness, improve circulation, and enhance overall recovery. However, the specific timing can vary based on the type of fracture and the surgical approach. It’s essential to follow your surgeon’s recommendations regarding when to start rehabilitation exercises.

4. Indications of Ligament Healing: The ability to bend your knee after a month of immobilization is a positive sign, but it does not necessarily confirm that your ACL has fully healed. Ligament healing is a complex process that can take several months. While some range of motion is a good indicator of progress, it’s crucial to have follow-up evaluations with your orthopedic surgeon or physical therapist to assess the integrity of the ligament and the overall stability of your knee joint. They may perform specific tests to evaluate the ACL and determine if additional interventions, such as further rehabilitation or surgical reconstruction, are necessary.

In conclusion, your recovery journey will involve close monitoring by your healthcare team, adherence to rehabilitation protocols, and patience as your body heals. It’s essential to maintain open communication with your medical providers, ask questions, and express any concerns you may have about your recovery process. Each patient’s healing timeline is unique, and your healthcare team will tailor your treatment plan to your specific needs and progress.
