Hallux Valgus also known as thumb outward deviation or twisting, is a common hand condition that can restrict hand function and even affect daily life. There are many different causes and symptoms of thumb deviation, and this article will introduce the causes, symptoms, diagnosis, and treatment methods of thumb deviation.
Causes
Hallux Valgus is usually caused by the following reasons:
Heredity: Some people are born with hand deformities, and thumb deviation may be one of them.
Arthritis: Hand arthritis can lead to joint inflammation and thumb deviation.
Repetitive stress: Repeated use of the fingers and wrists can damage the fingers and cause thumb deviation.
Hand fractures: Hand fractures can cause thumb deviation.
Other diseases: Diseases such as diabetes, thyroid problems, and Raynaud’s syndrome may also cause thumb deviation.
Symptoms
The symptoms of thumb deviation may vary depending on individual differences, but typically include:
Finger pain: When the thumb deviates, the finger may be painful and uncomfortable.
Finger stiffness: The flexibility of the finger is limited and cannot bend or straighten freely as before.
Finger weakness: Due to muscle or nerve damage, the finger may feel weak.
Finger swelling: Thumb deviation may cause swelling of the finger.
Abnormal finger appearance: The thumb may deviate or twist outward, causing an abnormal appearance of the finger.
Diagnosis
If thumb deviation is suspected, contact a doctor for diagnosis as soon as possible. The doctor will usually conduct a physical examination and ask about symptoms and medical history. If necessary, the doctor may also request X-rays or other imaging tests to understand the condition of the finger.
Treatment
The treatment of thumb deviation may vary depending on the patient’s condition. Here are several possible treatment options:
Physical therapy: Physical therapy can help improve the flexibility and strength of the fingers.
Medications: Over-the-counter and prescription medications may be used to relieve pain and reduce inflammation, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or locally applied heat or cold therapy.
Surgical treatment: In some cases, surgery may be the best option for treating thumb deviation. The type and method of surgery will vary depending on the patient’s condition. Surgery may include joint shaping, ligament reconstruction, joint replacement, and others. Rehabilitation therapy is required after surgery to restore finger function.
Braces: For some mild cases of thumb deviation, wearing braces may help alleviate symptoms and prevent the disease from further developing.
Lifestyle changes: Lifestyle changes may also help treat thumb deviation. Reduce repetitive hand stress activities such as typing, using a phone, and changing hand posture and finger usage can help alleviate symptoms.
Overall, treating thumb deviation requires individualized treatment through a variety of methods. Early detection and treatment can prevent the disease from progressing and improve treatment effectiveness. If you suspect you have thumb deviation, consult a doctor promptly for diagnosis and treatment.
