According to the information you provided, the initial diagnosis is congenital finger flexion deformity. The English term is “camptodactyly”, which means finger flexion deformity. A child with this deformity typically has flexed fingers that are not fully extended. This deformity often includes a number of deformities, such as skin tension, tendon and ligament abnormalities, and even bone abnormalities. The exact incidence is unknown, with varying degrees of deformity reported in approximately 1% of the population. The deformity can occur in infancy or even in adulthood, most often in the little finger, and is more common in girls than in boys. Most are solitary, and a few have a family history and can occur in multiple individuals from the same family. Sometimes it is accompanied by abnormalities in other areas. Diagnosis relies on a thorough physical examination by a specialist and sometimes an X-ray examination is required. For treatment, mild deformities often do not produce any discomfort or functional impairment and therefore do not require surgery. This deformity is often less than 30 degrees of finger flexion. It can be treated with functional training or rehabilitation, or with a brace or splint. For more severe deformities, especially in infants or minors, surgical treatment is often required. Since the appearance of the deformity is different for each patient, the surgical plan should be treated differently depending on the specific deformity. Surgical results are still good, but sometimes mild flexion deformities remain, and for severe ones, it is difficult to return to normal.
