Cracking Elbow and Weakness After Motorcycle Accident: When to Seek Help?

There is a popping sound on the outer side of the left elbow after the car accident?

On November 15, I was involved in a motorcycle accident where my motorcycle was rear-ended at a red light by another motorcycle traveling at high speed.
When I was thrown forward, I braced myself with my hands, and at that moment, both my wrist and elbow were very painful.
Additionally, there is a large bruise on the outer side of my left upper arm near the elbow (the bruise has faded but is not completely gone).
For several days after the accident, my hands were extremely weak, but they have mostly recovered now.
However, some movements still feel a bit weak, such as the action of wiping myself from behind, where I lift my hand from below to above; the muscles on the inner side of my forearm feel somewhat painful and weak.
When I extend or bend my left elbow, there is often a cracking sound (I feel the sound comes from the outer side of the elbow), but it is not painful and I don't have much sensation.
After the accident, both of my elbows were X-rayed at an orthopedic clinic, but the doctor did not mention any issues with my left arm (it should not be fractured).
At that time, I felt that my left arm was not severely injured (as my focus was on the fracture issue with my right arm, which has since had the cast removed and is undergoing rehabilitation).
Recently, I have noticed that there is still a cracking sound from the outer side of my left elbow.
I would like to know if the weakness in some movements of my left arm and the frequent cracking sound in my elbow will heal on their own? If it does not improve after a certain period, when should I see a doctor?

Hello, if an X-ray is taken and the angle does not capture the fracture or if there was no displacement at the time, it is possible that the fracture may go unnoticed, which can result in ongoing pain.
In such cases, it may be necessary to repeat the X-ray or arrange for other examinations.
If you are experiencing clicking sounds or weakness in your left hand that is causing you concern, you may want to consult your physician for further advice.
Wishing you good health.
Sincerely, Shen Bo-Chuan.

More Info

After a motorcycle accident, experiencing cracking sounds in the elbow and weakness in the arm can be concerning, especially when there was significant trauma involved. Based on your description, it seems that you have sustained some injuries that may not have been fully addressed during your initial medical evaluation.
Firstly, the cracking sound you hear in your elbow, known as crepitus, can occur for several reasons. It may be due to the movement of tendons or ligaments over the bony structures of the elbow, or it could indicate some underlying issues such as cartilage damage or joint instability. The fact that you are experiencing weakness and pain in specific movements, particularly when lifting your arm, suggests that there may be some soft tissue injury, such as a strain or sprain, affecting the muscles or tendons around the elbow.

Given that you have already had X-rays taken, which did not show any fractures, it is a positive sign that there are no broken bones. However, X-rays do not always reveal soft tissue injuries, which are common in cases of trauma. Conditions such as tendonitis, ligament sprains, or even minor tears in the muscles can lead to the symptoms you are experiencing.
In terms of recovery, many soft tissue injuries can heal on their own with time and appropriate care. However, if you continue to experience weakness and the cracking sound persists, it is advisable to seek further medical evaluation. A follow-up with an orthopedic specialist or a physical therapist could provide you with a more comprehensive assessment. They may recommend imaging studies such as an MRI, which can give a clearer picture of the soft tissues and help identify any potential injuries that were not visible on X-rays.

In the meantime, there are several steps you can take to aid your recovery:
1. Rest and Ice: Allow your elbow to rest and apply ice to reduce any swelling or inflammation. Avoid activities that exacerbate the pain or weakness.

2. Gentle Range of Motion Exercises: Once the acute pain subsides, gentle stretching and range of motion exercises can help maintain flexibility and prevent stiffness. However, avoid any movements that cause pain.

3. Strengthening Exercises: As you regain strength, gradually incorporate strengthening exercises for the forearm and elbow. This can help improve stability and function.

4. Physical Therapy: A physical therapist can provide tailored exercises and treatments to help restore strength and function to your elbow. They can also teach you proper techniques to avoid further injury.

5. Monitor Symptoms: Keep track of your symptoms. If you notice worsening weakness, increased pain, or if the cracking sound becomes associated with pain, it is crucial to seek medical attention promptly.

In summary, while some symptoms may resolve with time, persistent weakness and unusual sounds in the elbow warrant further investigation. If you do not see improvement in the next few weeks or if your symptoms worsen, it is essential to consult a healthcare professional for a thorough evaluation and appropriate management. Early intervention can significantly impact your recovery and help you return to your normal activities, especially if you are an athlete or engage in physical activities regularly.
