Neonatal skeletal fractures. Birth trauma or child abuse?
Insights
Fracture age in newborns can be estimated by observing calcification, appearing as early as seven days post-birth. Absence of calcification after 11 days may indicate infant abuse.
Area of Science:
- Pediatric Radiology
- Skeletal Development
- Forensic Radiology
Background:
- Distinguishing birth-related fractures from non-accidental trauma in neonates is crucial.
- Radiographic assessment of fracture age is vital for clinical and legal purposes.
- Calcification patterns offer insights into fracture healing timelines.
Purpose of the Study:
- To evaluate the utility of calcification in estimating the age of neonatal fractures.
- To identify typical fracture sites and associated conditions in newborns.
- To establish radiographic indicators for potential infant abuse.
Main Methods:
- Retrospective review of radiographic films from 23 neonates with delivery-related fractures.
- Analysis of fracture locations (clavicle, humerus, femur) and presence/absence of calcification.
- Correlation of calcification timing with infant age and clinical findings.
Main Results:
- Calcification was observed as early as 7 days post-birth and absent up to 11 days.
- Femoral fractures were frequently associated with neuromuscular conditions (6 of 7 cases).
- Fractures at unusual sites or lacking calcification by 11 days warrant further investigation.
Conclusions:
- Radiographic calcification is a valuable tool for dating neonatal fractures.
- Unusual fracture locations or delayed calcification may suggest non-accidental trauma.
- Radiologists should consider abuse in cases with atypical fracture presentation or delayed healing signs.
Abstract:
When a fracture is discovered in a newborn infant, it is important to decide whether it occurred at birth or after birth. Calcification around the fracture site gives a useful estimate of the age of the fracture. We reviewed films of 23 patients with fractures resulting from delivery. The fractures occurred at three different sites: the clavicle, the humerus, and the femur. Calcification could be seen as early as seven days after birth and was absent for as long as 11 days after birth. Six of seven femoral fractures occurred in infants with neuromuscular problems. Fracture at an unusual site or absence of calcification after 11 days should alert the radiologist to the possibility of abuse.

01:27Fractures: 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...
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...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
