BACKGROUND Allograft biopsies are the gold standard for evaluating renal graft dysfunction. Adult-sized kidney (ASK) allografts are placed extraperitoneally in older children and adults and transperitoneally in infant recipients. Transperitoneal graft biopsies may be accompanied by a greater risk of bleeding and bowel injury, although no standardized(More)
RATIONALE AND OBJECTIVES The frequency and morphology of central acetabular osteophyte formation were evaluated in patients with osteoarthritis. METHODS One hundred preserved acetabular specimens were evaluated for the occurrence of central osteophytes (excrescences present in the articulation of the hip joint), their relationship to marginal and femoral(More)
OBJECTIVE The purpose of this study was to describe the clinical, imaging, and surgical findings in the cases of four neonates with radiographic findings suggesting duodenal atresia (double-bubble sign) who were subsequently found to have malrotation with midgut volvulus. CONCLUSION When the surgical treatment of a patient with the double-bubble sign is(More)
PURPOSE To determine how signal intensity in the cartilaginous distal part of the femoral epiphysis varies with (a) age, (b) sex, and (c) distribution to the medial or lateral condyle on magnetic resonance (MR) images. MATERIALS AND METHODS Sixty-six sagittal T2-weighted or inversion-recovery MR images of the distal femoral epiphysis in children aged 2(More)
This is a retrospective review of pedicle screw placement in adolescent idiopathic scoliosis (AIS) patients under 18 years of age who underwent robot-assisted corrective surgery. Our primary objective was to characterize the accuracy of pedicle screw placement with evaluation by computed tomography (CT) after robot-assisted surgery in AIS patients. Screw(More)
RATIONALE AND OBJECTIVES Neonates are at increased risk for cold stress and hypothermia in cool environments. An infant transport mattress (ITM) is commonly used to increase neonate temperature during transport and has been used during CT scanning. This study determined the impact of an ITM on radiation dose and image artifacts during CT scanning. (More)
Osteochondral lesions of the elbow are injuries that disrupt the cartilage and subjacent bone, and they most commonly involve the capitellum. The staging, prognosis, and treatment of osteochondral lesions in the elbow are based on a combination of radiographic, magnetic resonance imaging, and arthroscopic findings. Radiographic staging includes the(More)
With increasing participation and intensity of training in youth sports in the United States, the incidence of sports-related injuries is increasing, and the types of injuries are shifting. In this article, the authors review sports injuries of the lower extremity, including both acute and overuse injuries, that are common in or specific to the pediatric(More)
Two-dimensional image guidance and navigation can help to reduce the number of misplaced pedicle screws, but do not completely prevent misplacement. This experimental, retrospective, non-inferiority study was designed to evaluate and compare the efficacy of a novel 3D imaging technique versus conventional postoperative CT-scan, for intra-operative(More)
