After the car accident, the fingers cannot be straightened?

Hello Doctor, about 20 days ago I was involved in a car accident, which resulted in fractures of the bones in my left forearm, the outer side of the elbow, and the inner side of the upper arm.
I underwent surgery 10 days ago, and I have just started to move my left fingers postoperatively.
Currently, except for my middle finger, I am unable to fully extend my left fingers; they can only form an L shape.
I can only position my hand palm down without any strength, and aside from my middle and little fingers, I cannot lift the others.
Since about 10 days post-surgery, I have been doing self-rehabilitation, and I have noticed gradual improvement in the angle and strength of my finger extension.
I have an electromyography (EMG) scheduled in about a week, and I am quite anxious.
Doctor, could this be due to injury or rupture of the ulnar nerve, radial nerve, or other hand nerves from the impact? I am very concerned about serious issues that might require another surgery, so I came here to seek your advice.
Thank you for your response.

Hello: I'm not sure about the function of your sensory nerves.
If there is damage to the ulnar nerve, radial nerve, or median nerve, you may experience related sensory abnormalities.
If there are limitations in motor function, it may be necessary to consider issues with the skeletal muscles and ligaments.
Regarding the repair of nerves and body tissues, it is recommended to supplement with B vitamins and protein, ensure adequate sleep, and control risk factors such as smoking, etc.
It is advisable to undergo electromyography (EMG) testing and then discuss with a rehabilitation physician about physical therapy and occupational therapy.
Wishing you good health and peace.

More Info

After a car accident, it's not uncommon to experience various complications, especially when it involves the upper extremities. In your case, the inability to straighten your fingers following surgery for a fracture in the hand is concerning and warrants careful evaluation.

From your description, it seems you have undergone surgery for a fracture in the bones of your hand, and now you are experiencing limited mobility in your fingers, particularly the inability to extend them fully. The fact that your fingers can form an "L" shape but cannot be straightened suggests there may be an issue with the tendons, nerves, or both.
The nerves that are primarily responsible for finger movement include the ulnar nerve and the radial nerve. The ulnar nerve controls the movement of the little finger and part of the ring finger, while the radial nerve is responsible for extending the wrist and fingers. If either of these nerves was injured during the accident or during the surgical procedure, it could lead to the symptoms you are experiencing.
Additionally, the tendons that control finger movement could also be affected. Tendon injuries can occur due to direct trauma or as a result of swelling and inflammation following surgery. If the tendons are not functioning properly, it can lead to a loss of strength and range of motion in the fingers.

Given that you are scheduled for an electromyography (EMG) test, this is a crucial step in determining the integrity of the nerves in your arm and hand. The EMG will help assess the electrical activity of the muscles and can indicate whether there is nerve damage. If nerve damage is confirmed, further intervention may be necessary, which could include surgical repair, especially if the nerve is severed or significantly compressed.

In the meantime, it is essential to continue with your rehabilitation exercises as advised by your healthcare provider. Gentle stretching and strengthening exercises can help improve mobility and function in your fingers. However, it is crucial to avoid any activities that cause pain or discomfort, as this could exacerbate the problem.

If you notice any worsening of symptoms, such as increased pain, swelling, or changes in sensation (like numbness or tingling), you should contact your healthcare provider immediately. These could be signs of complications that require prompt attention.

In summary, the inability to straighten your fingers after surgery could be due to nerve or tendon issues resulting from the accident or the surgical procedure. The upcoming EMG will provide valuable information to guide your treatment. It is understandable to feel anxious about the possibility of needing further surgery, but addressing these concerns with your healthcare provider can help clarify your situation and outline the best course of action for recovery. Remember, recovery can take time, and patience is key as you work towards regaining full function of your hand.
