The child's thumb cannot be straightened

Parents should pay special attention to observing their children during their growth and development so as to detect problems and treat them in a timely manner. When a child's thumb cannot be straightened, attention should be paid to the joint deformity, also known as trigger thumb disease. The main feature is that the joint has no elasticity and cannot be straightened, and there will be a popping sound when passively straightened. The treatment of this disease should be carried out after the child is three years old, and it is usually corrected by surgery, which has a good effect.

What are the reasons why children's left thumb cannot be straightened?

1. Trigger thumb. Trigger thumb deformity is divided into 4 stages: Stage I (tumor type) manifests as local Notta's nodules, but there is no snapping during flexion and extension of the phalangeal joints; Stage II (active snapping type) manifests as snapping during active dorsiflexion of the interphalangeal joints;

2. Stage III (passive snapping type) is characterized by the inability of the interphalangeal joints to be actively extended, and snapping occurs during passive extension; Stage IV (rigid type) is characterized by the inability of the interphalangeal joints to be passively extended (i.e., there is a fixed flexion deformity). Patients with trigger thumb have fixed flexion deformity of the interphalangeal joints.

3. Treatment: Delaying surgery until the age of 3 years will not have a negative impact on joint contracture or mobility function. Therefore, an appropriate period of observation is reasonable, especially for children younger than 1 year old. Children older than 1 year who present with painful snapping and fixed flexion deformity (stage IV) require surgery.

4. Thumb clasping deformity. Type I thumb clasping deformity is milder and is characterized by the absence or poor development of the thumb extensor mechanism. Type II hallux claustrophobia is more complex, with symptoms such as joint contracture, lateral ligament abnormalities, thumb and mouth contracture, and thenar muscle abnormalities. Type III buckle deformity with joint

Contractures or other related syndromes.

5. Treatment: Type 1 can be treated conservatively, while types 2/3 must be treated surgically, and surgical treatment can be started at around 1 year old.

How to treat thumb deformity

1. Finger deformity can be treated and requires choosing a professional hand and foot surgery hospital for treatment. For those with severe finger deformities, a surgical plan needs to be developed based on the patient's film examination results, and multiple operations should be performed depending on the child's condition. Don't worry too much. It is recommended to wait until the child is about 6 months old and go to a specialist hospital for diagnosis and treatment. Choose the treatment time according to the specific situation.

2. The treatment for congenital hand deformities is mainly surgical, and patients must be cautious when choosing. The best time to treat congenital hand deformities is not the older the age. On the contrary, the earlier the treatment, the better the effect. Generally, surgical treatment can be performed 6 months after the child is born.

During the child's development, special attention must be paid, especially to issues such as fetal malformations. Prenatal examinations can check whether the child is deformed. If the child is unhealthy, timely measures can be taken. Therefore, pregnant women must undergo prenatal examinations in a timely manner to reduce the impact on the pregnant woman and the fetus. For developmental problems after birth, in addition to supplementing adequate nutrition, it is important to pay attention to correcting the problem in a timely manner.
