Bone growth in thalassaemic children
Insights
Children with thalassemia showed normal bone length growth until age 11, after which it decreased. Bone width growth was initially faster in these children, and bone age retardation was more common after age 7.
Area of Science:
- Pediatric Endocrinology
- Orthopedics
- Hematology
Background:
- Thalassemia is a genetic blood disorder affecting hemoglobin production.
- Bone abnormalities are a known complication in children with thalassemia.
- Understanding skeletal growth patterns is crucial for managing thalassemia complications.
Purpose of the Study:
- To investigate the impact of thalassemia on metacarpal bone growth in children.
- To compare bone length and width dimensions between thalassemic and control groups.
- To assess the correlation between thalassemia and bone age retardation.
Main Methods:
- X-ray measurements of the 3 middle metacarpal bones (length and width) were performed.
- A cohort of 61 children with thalassemia and 35 healthy controls (aged 5-13 years) was studied.
- Bone age was assessed in both groups.
Main Results:
- Thalassemic children exhibited normal bone length growth until age 11, followed by reduced growth.
- Bone width growth in thalassemic children exceeded controls until age 11, then became comparable.
- A higher proportion of thalassemic children showed bone age retardation after 7 years of age.
Conclusions:
- Thalassemia significantly affects metacarpal bone growth, particularly after age 11.
- Altered bone width and length patterns are observed in children with thalassemia.
- Bone age retardation is a more frequent finding in thalassemic children over 7 years old.
Abstract:
X-ray measurements were made of the length and width of the 3 middle metacarpal bones of both hands, in 61 thalassaemic and 35 control children of both sexes aged 5--13 years. Growth in length of the bone was normal until age 11 years but after this it was smaller in thalassaemic children. The growth of total width in thalassaemic children was greater than that of the controls until age 11 years and then became equal. The proportion of children with bone age retardation was greater after 7 years.

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
