Insights
Very low birth weight infants can develop rickets and fractures. Risk factors include medical therapies and specific physical therapies, necessitating early recognition and appropriate treatment.
Area of Science:
- Neonatalogy
- Pediatric Orthopedics
- Nutritional Science
Background:
- Very low birth weight (VLBW) infants (<1500 g) are susceptible to nutritional deficiencies and complications.
- Developmental rickets and fractures can significantly impact VLBW infants' long-term health and development.
Purpose of the Study:
- To identify the incidence and characteristics of rickets and fractures in VLBW infants.
- To determine risk factors associated with these conditions in VLBW infants.
- To outline appropriate management strategies for VLBW infants diagnosed with rickets and fractures.
Main Methods:
- A retrospective review of 247 VLBW infant cases over 42 months.
- Diagnosis of rickets and fractures based on clinical and radiological findings.
- Analysis of risk factors including medical history, therapies, and physical interventions.
Main Results:
- Rickets diagnosed in 39% (96/247) of infants at a mean age of 50 days.
- Fractures diagnosed in 10.5% (26/247) of infants at a mean age of 75 days.
- A total of 98 fractures were observed in 26 infants, with ribs being the most common site.
Conclusions:
- VLBW infants face a significant risk of developing rickets and fractures.
- Hepatobiliary disease, total parenteral nutrition, diuretic therapy, and specific physical therapies are identified risk factors.
- Early diagnosis and management with metabolic therapy and splinting are crucial for optimal outcomes.
Abstract:
A syndrome in very low birth weight premature infants weighing less than 1500 g is evidenced by developmental nutritional rickets and fractures at 75 days of age. In a review conducted over 42 months, 247 very low birth weight cases were identified. Rickets was diagnosed in 96 (39%) infants whose mean age was 50 days and fractures were diagnosed in 26 (10.5%) infants whose mean age was 75 days. These 26 infants experienced 98 fractures: 10 humerus, 13 radius, 8 ulna, 4 metacarpal, 3 clavicle, 54 ribs, 5 femur, and 1 fibula. Risk factors included hepatobiliary disease, total parenteral nutrition, diuretic therapy, physical therapy with passive motion, and chest percussion therapy. With early recognition, metabolic therapy and splinting, not casting, are appropriate treatments.

The Functions of the Skeletal System
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Bone 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...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
