Incomplete Fractures of Distal Long Bones Among Children in Early Stages of Mobility: Few Concerns for Physical Child

Objectives:
This study aimed to describe the characteristics, reported mechanism of injury, fracture morphology, and level of physical abuse concern among children in the early stages of mobility diagnosed with an incomplete distal extremity long bone fracture.
Methods:
A retrospective chart review was performed for all children aged 10 to 12 months with an incomplete fracture of a distal forearm or distal lower limb who were reportedly pulling up, cruising, or ambulating, and who were evaluated by the child abuse pediatrics team at a single pediatric level I trauma center.
Results:
Of the 29 patients who met inclusion criteria, the child abuse pediatrics team had concerns about physical child abuse for 3 children. Not every case with an unknown or discrepant history of injury was deemed concerning for abuse, but all 3 for whom the team determined that concern was warranted had an unknown or discrepant history. All 3 of these children had distal forearm fractures; 1 child had multiple concomitant fractures (including a scapular fracture), and 2 had evidence of bone healing at initial presentation. Each of these observations raises concern for abusive injury based on current evidence. Both-bone buckle fractures of the radius/ulna and tibia/fibula were the most common type of incomplete distal fracture.
Conclusions:
This age group presents a unique challenge when designing evidence-based algorithms for the detection of occult injuries in emergency departments. Incomplete fractures of a distal limb are commonly related to a fall and may be considered "low specificity" for physical abuse. However, some publications conclude they should prompt universal physical abuse screening. Our small study indicated that the presence or absence of certain risk factors may provide additional information which could help guide the need for a more thorough evaluation for occult injury in early-mobile children with incomplete distal extremity long bone fractures. Ongoing research is warranted.

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...
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...

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...
