Eighty-one pediatric patients with a variety of spinal disorders, including suspected dysrhaphism, scoliosis, neoplasia, and neurofibromatosis, underwent magnetic resonance (MR) imaging. The results were retrospectively compared with those of myelography followed by computed tomography (CT) and surgery. In patients with dysrhaphism, most abnormalities,(More)
Congenital clubfoot is a common problem of uncertain etiology with a broad spectrum of clinical severity. Much remains controversial and unsolved about this disorder. It is agreed, however, that early management should be conservative and that operative management should comprehensively address the deformities, to avoid if possible, subsequent operations.(More)
A retrospective analysis of 96 patients who underwent an epiphysiodesis procedure for leg length discrepancy was performed. Forty patients were identified who had an open Phemister-type epiphysiodesis. Fifty-six patients underwent a percutaneous epiphysiodesis procedure. All patients' medical records and radiographs were reviewed for complications. No(More)
The purpose of this study was to determine the method of treatment for open fractures in pediatric patients that is used and taught at academic orthopedic residency programs. A web-based survey was constructed and emailed to program directors of orthopedic residencies. Seventy programs out of a total of 140 surveyed programs responded. Data were tabulated(More)
Seventy-eight diaphyseal femur fractures in 77 children were stabilized with flexible intramedullary nails. The patients ranged in age from 2 + 9 to 18 years. All patients had open femoral growth plates at the time of fixation. Eleven percent of the fractures had an average varus or valgus malalignment of 6 degrees. Eight percent of the fractures had an(More)
A method of recording a residual limb indentation stiffness map was developed for possible use as an aid in calculating prosthetic socket rectifications. The method was tested to determine the level of repeatability attainable. A hand-held, pencil-like device was used, with an air-driven piston that indented the tissue 10 times per second. The indentor tip(More)
One hundred patients with a diagnosis of congenital scoliosis were reviewed with regard to their urologic history, chemistries, and excretory urography. A 40% incidence of urologic abnormality was found in these asymptomatic patients. Twenty-five additional patients were evaluated by excretory urography and ultrasonography. Of six patients identified by(More)
The use of prostaglandin-E1 (PGE1) to maintain patency of the ductus arteriosus in infants with ductal-dependent congenital heart disease is now well established. A 2.5-month-old child with cyanotic heart disease who required long-term PGE1 infusions; developed widespread periosteal reactions during the course of therapy. Prostaglandin-induced subperiosteal(More)
