As the saying goes, 'At 3 years old, one looks older; at 7 years old, one looks older.' This means that 3 years old determines a baby's life. You may think this is just an old saying, but in fact, growth and development before the age of 3 can affect their entire life. So parents should always care about and pay attention to their baby's physical condition. So what if they find that their 3-year-old baby's thumb is difficult to straighten?
1、 What's wrong with a 3-year-old baby's thumb not reaching straight
Considering whether the child is iron or zinc deficient, it is recommended to test for trace elements. If it is actively supplemented, then consider whether the child has neurological problems or tendinitis. It is necessary to actively regulate and massage appropriately, and be careful not to exert excessive force. I suggest that you go to the health department of a children's hospital to have a health check-up for your baby, including blood routine, bone alkaline phosphatase, and trace elements to help diagnose and treat. You should also let your baby eat more milk, eggs, and lean meat to strengthen nutrition and supplement calcium and iron elements.
2、 Childhood tenosynovitis
Pediatric tenosynovitis, also known as stenosing tenosynovitis or trigger finger, is a common congenital deformity in children. Due to the fact that the flexor tendon is located at the distal end of the metacarpophalangeal joint and is narrowed by fibrocartilaginous lesions of the tendon sheath, the proximal tendon thickens or becomes nodular, causing the interphalangeal joint to be in a flexed position and unable to extend actively. Passive extension can cause pain or clicking.
Children with snapping fingers generally do not experience symptoms at birth, and it is common to present with finger flexion and inability to straighten at around 6 months to 2 years old. The most common location is at the metacarpophalangeal joint of the second and third fingers of the thumb, where a circular protrusion and hard lump can be felt, with mild tenderness and a bouncing sensation during extension and flexion. The interphalangeal joint is in a fixed flexed state, and there is a bouncing sensation when moving and extending.
When a 3-year-old child is sensitive, if their fingers need some time for treatment or adjustment, the child will inevitably have a sense of inferiority about the condition of their fingers. Therefore, if the situation is severe and surgery is needed, parents' encouragement and care are also needed during this period. It should be noted that mental health is more important than physical health. Children should not be left with shadows because of this.
