Electrical injuries resulting in physeal injury in children are an uncommon but well-recognized clinical entity. Almost all these injuries are sustained from man-made electrical sources. ⋯ The authors report the case of a 12-year-old girl who survived a lightning strike 2 years ago and who presented with asymmetric growth arrest in both legs. The authors discuss the pathophysiology of lightning strike and consider the evidence for direct electrical injury versus ischemic insult to the physis as explanations for the cause of the growth arrest observed in this patient.

Compartment syndrome can be difficult to diagnose in a child, with delays in diagnosis leading to disastrous outcomes. Thirty-six cases of compartment syndrome in 33 pediatric patients were treated at the authors' institution from January 1, 1992, to December 31, 1997. There were 27 boys and 6 girls, with nearly equal upper and lower extremity involvement. ⋯ Pain, pallor, paresthesia, paralysis, and pulselessness were relatively unreliable signs and symptoms of compartment syndrome in these children. An increasing analgesia requirement in combination with other clinical signs, however, was a more sensitive indicator of compartment syndrome: all 10 patients with access to patient-controlled or nurse-administered analgesia during their initial evaluation demonstrated an increasing requirement for pain medication. With early diagnosis and expeditious treatment, >90% of the patients studied achieved full restoration of function.

Radial neck nonunion in children is a rare complication of a displaced radial neck fracture. The authors conducted a retrospective review of nine cases of radial neck nonunion in an effort to identify risk factors for nonunion and to evaluate treatment options. Nine patients, average age 8.2 years, sustained displaced Salter-Harris type II fractures of the radial neck, with average angulation of 83 degrees and average displacement of 83%, and elbow dislocation or additional fracture in eight of nine patients. ⋯ Healing of the nonunion did not necessarily lead to improvement of clinical symptoms. Severity of initial fracture displacement and inadequate fixation technique contributed to radial neck nonunion. Treatment of the nonunion should depend on the patient's pain, deformity, and functional restriction.
