Tear of the ligament in the right thumb?


Hello! Doctor, in late March, I sustained an injury to my right thumb due to external force, resulting in swelling.
At that time, I underwent X-rays and an MRI, which diagnosed no bone damage but indicated a partial ligament tear, classified as a grade I to II sprain.
I have been wearing a splint and actively participating in rehabilitation, but since mid-May, my recovery progress has stagnated.
The first joint of my right thumb is still protruding, enlarged, and widened, and sometimes it makes a cracking sound when I move it.
Now, after more than three months, my finger's range of motion has not improved; I still cannot bend it, and sometimes I cannot even force it down with my hand.
The rehabilitation team suggested shockwave therapy, but after three sessions, the results have not been satisfactory.
After prolonged activity, my finger joint swells, turns red, and hurts; sometimes I feel pain even while wearing the splint.
During my last follow-up visit, another X-ray was taken, which again showed no issues with the bones, and there was no joint laxity or dislocation.
However, my attending physician recommended surgery, suggesting that there may be soft tissue trapped in the first joint that X-rays and MRIs might not reveal, and that surgery would be necessary to determine the issue.

Q1.
Generally, how long does it take for a ligament tear in the thumb to heal?
Q2.
Is the joint protrusion indicative of bone growth? Could it be a bone tumor?
Q3.
Is surgery truly necessary for my condition? Will there be any sequelae after the surgery?
Q4.
Should I continue with shockwave therapy?
Thank you for your answers, as I am beginning to worry that there might be an underlying bone issue that is preventing my recovery.

Hello, thank you for your inquiry.
Here are the responses:
Q1: How long does it take for a general thumb ligament tear to heal? 2-3 months.

Q2: The joint protrusion is due to periosteal or soft tissue proliferation.
MRI indicates that there is no damage to the bone, so it is unlikely to be a bone tumor.

Q3: If the pain and discomfort persist, surgery may be necessary.
The main postoperative complications are infection and joint stiffness, which can lead to limited mobility.

Q4: Should I continue with shockwave therapy? It is recommended to pause the treatment.
Based on your description of the condition, a partial ligament tear cannot be ruled out, so it is advisable to visit a hand surgery clinic for further evaluation.

Hello! Thank you for reaching out with your concerns regarding your thumb ligament injury. I understand that dealing with a ligament tear can be frustrating, especially when recovery seems to stall. Let’s address your questions one by one.


Q1: How long does it typically take for a thumb ligament tear to heal?
The recovery time for a thumb ligament tear can vary significantly depending on the severity of the injury. Generally, a Grade I sprain (mild) may take a few weeks to heal, while a Grade II sprain (moderate) can take anywhere from 4 to 8 weeks. However, since you mentioned that your injury has been classified as a Grade I to II sprain and you have been experiencing a plateau in your recovery for over three months, it may indicate that the healing process is not progressing as expected. Factors such as age, overall health, and adherence to rehabilitation protocols can also influence recovery time.


Q2: Is the swelling and enlargement of the joint due to bone growth or a possible bone tumor?
The swelling and enlargement of the joint could be due to several factors, including inflammation from the injury, joint effusion (fluid accumulation), or even a condition known as synovitis (inflammation of the joint lining). While bone spurs (osteophytes) can develop in response to chronic irritation, the likelihood of a bone tumor is relatively low, especially if imaging studies have not indicated any abnormalities. However, persistent swelling and changes in the joint should be monitored closely, and if there are any concerns, further imaging or evaluation may be warranted.


Q3: Do I really need surgery? What are the potential after-effects?
Your doctor’s recommendation for surgery likely stems from the suspicion that there may be soft tissue entrapment or other issues that are not visible on standard imaging. Surgery can provide a definitive diagnosis and treatment, especially if conservative measures have failed. The potential risks of surgery include infection, stiffness, and the possibility of incomplete recovery. However, many patients experience significant improvement after surgical intervention, especially if conservative treatments have not yielded results. It’s crucial to weigh the potential benefits against the risks and discuss your concerns with your surgeon.


Q4: Should I continue with shockwave therapy?
Shockwave therapy can be beneficial for certain musculoskeletal conditions, particularly for chronic pain and inflammation. However, if you have undergone multiple sessions without noticeable improvement, it may be worth discussing alternative treatment options with your rehabilitation team. They may suggest other modalities, such as physical therapy, ultrasound therapy, or even corticosteroid injections, depending on your specific situation.


Additional Considerations
Given that you have been experiencing persistent symptoms for over three months, it may be prudent to seek a second opinion from another orthopedic specialist, particularly one who specializes in hand and wrist injuries. They can provide further insights into your condition and help determine the best course of action.

In the meantime, continue to follow your rehabilitation program, and ensure you are not overexerting your thumb. Ice, rest, and elevation can help manage swelling, and maintaining a dialogue with your healthcare providers is essential for navigating your recovery journey.

Remember, recovery from ligament injuries can be a slow process, and it’s important to be patient and proactive in your treatment. I wish you the best in your recovery and hope you find relief soon!
