Electrical injury involving the immature skeleton

Area of Science:

• Orthopedics
• Skeletal Biology
• Pediatric Bone Health

Background:

• Electrical impulse propagation through immature skeletons can lead to significant skeletal development and functional problems.
• Assessing histologic and morphologic changes in immature bone following electrical injury is crucial for understanding its impact.

Observation:

• Electrical damage destroyed trabecular bone in metaphyses and epiphyseal ossification centers.
• Morphologic irregularities and growth cessation were observed in the physis (growth plate).
• Severe fibrous ankylosis of the knee joint and localized arrest of the proximal tibial physis were noted.

Findings:

• Complete cessation of growth occurred in the proximal tibia due to presumed electrical ablation of the physis.
• No significant callus formation, inflammatory response, or new bone formation was observed over a year post-injury.
• Valgus/recurvatum deformation resulted from localized physeal arrest, with differential growth effects on the tibia and fibula.

Implications:

• Electrical injuries pose a significant risk to pediatric skeletal development, potentially causing permanent deformities.
• Understanding these electrical injury mechanisms is vital for developing targeted interventions and improving patient outcomes.
• This study highlights the vulnerability of the immature skeleton to electrical damage, necessitating careful management and follow-up.
