Difficulty in Straightening or Bending the Ring Finger: Causes and Solutions

The ring finger cannot be straightened or bent?

Dr.
Chu, I personally completed the repainting of my house.
However, the next day after sleeping, I found that I could not control the movement of my ring finger; I need to use my left hand to assist it.
If I try to force it to straighten or bend, it requires a lot of effort and is painful.
What should I do, or should I schedule an outpatient rehabilitation appointment? Thank you.

Mr.
Mocca, based on your description of the symptoms "inability to control the extension or flexion of the ring finger, requiring assistance from the left hand," it seems you may have developed "trigger finger." The treatment for trigger finger involves three steps: initially, mild cases can be managed with medication; next, corticosteroid injections may be considered; if symptoms persist and recur, surgical intervention may be necessary.
Sincerely, Dr.
Chu Bo-jun, Orthopedic Specialist.

More Info

Difficulty in straightening or bending the ring finger can be attributed to several potential causes, including tendon injuries, joint issues, or conditions like trigger finger. Given your description of the symptoms following a physically demanding task such as painting, it is possible that you may have developed a condition related to overuse or strain.

One common cause of difficulty in finger movement is trigger finger, also known as stenosing tenosynovitis. This condition occurs when the tendons that control finger movement become inflamed, leading to a catching or locking sensation when trying to bend or straighten the finger. It can be exacerbated by repetitive gripping or forceful activities, which may explain your symptoms after completing a physically demanding task.

Another possibility is a tendon injury. If you experienced any trauma or overexertion while painting, it could have led to a strain or partial tear of the tendons that control the movement of your ring finger. This could result in pain and difficulty in moving the finger, as you described.

In terms of treatment, the first step is to rest the affected finger and avoid activities that exacerbate the pain. Applying ice to the area can help reduce inflammation and alleviate discomfort. Over-the-counter anti-inflammatory medications, such as ibuprofen or naproxen, may also be beneficial in managing pain and swelling.

If symptoms persist, it is advisable to seek medical attention. A healthcare professional can perform a physical examination and may recommend imaging studies, such as an X-ray or ultrasound, to assess for any underlying injuries or conditions. Depending on the diagnosis, treatment options may include:
1. Physical Therapy: A physical therapist can provide exercises to improve flexibility and strength in the finger, which may help restore normal function.

2. Splinting: A splint may be recommended to immobilize the finger and allow the tendons to heal properly. This is particularly important in cases of trigger finger.

3. Corticosteroid Injections: If conservative measures do not provide relief, corticosteroid injections into the tendon sheath may help reduce inflammation and improve mobility.

4. Surgery: In severe cases, particularly with trigger finger that does not respond to other treatments, surgical intervention may be necessary to release the constricted tendon.

Regarding your concern about whether you should seek rehabilitation, it is indeed a good idea to consult with a healthcare provider, especially if you are experiencing significant pain or functional limitations. Early intervention can often lead to better outcomes and prevent further complications.

In summary, the difficulty in straightening or bending your ring finger could be due to several factors, including tendon inflammation or injury. Rest, ice, and anti-inflammatory medications are initial steps you can take. However, if symptoms persist, a visit to a healthcare professional is recommended for a thorough evaluation and appropriate treatment plan.
