OBJECT After primary repair of a myelomeningocele or a lipomyelomeningocele, patients can present with symptoms of secondary tethered cord syndrome (TCS). After surgical untethering, a small percentage of these patients can present with multiple repeat TCS. In patients presenting with secondary or multiple repeat TCS, the role as well the expected outcomes(More)
An approach to the problem of comparative analysis of objects and their surfaces that arises in medical imaging is presented and illustrated with an application to postsurgical bone-graft separation. A common requirement in medical imaging applications is the registration of multiple representations of the object prior to mensuration. The modeling of the(More)
OBJECT This prospective, randomized, placebo-controlled, double-blind trial was undertaken to assess the efficacy of aprotinin in reducing the need for blood transfusions in 39 children undergoing reconstructive craniofacial surgery. METHODS Two demographically similar groups--a total of 39 patients with a mean age of 1.2 +/- 1.2 years--were studied. The(More)
The hypothesis that the exons of eukaryotic structural genes code for functional domains and that the partitioned arrangement of coding information may thus serve to mediate the rapid evolution of new and unique proteins from pre-existing exons is also supported by our recent studies which demonstrate that the product of the central exon of the human(More)
OBJECT Chiari malformation (CM) Type I is frequently associated with craniosynostosis. Optimal management of CM in patients with craniosynostosis is not well-established. The goal of this study was to report on a series of pediatric patients with both craniosynostosis and CM and discuss their management. METHODS The authors searched the medical records of(More)
OBJECT Successful surgical repair of unicoronal plagiocephaly remains a challenge for craniofacial surgeons. Many of the surgical techniques directed at correcting the stigmata associated with this craniofacial deformity (for example, ipsilateral supraorbital rim elevation [vertical dystopia], ipsilateral temporal constriction, C-shaped deformity of the(More)
OBJECTIVE We report our experience with a previously undescribed method of myelomeningocele closure, which is the use of bilateral lumbar periosteal flaps as an additional tissue layer in complex cases. These flaps reinforce the dural repair, act to protect the spinal cord, and may help to contain any potential cerebrospinal fluid leak from the primary(More)
PURPOSE A trend in large myelomeningocele defect repair involves soft tissue closure with muscle and fascial flap techniques to provide a durable, protective, and tension-free soft tissue covering. We propose that composite tissue closure yields superior outcomes regardless of defect size. METHODS We present a retrospective review of our 15-year,(More)
PURPOSE: Previous studies have demonstrated the efficacy of 3D-printed bioactive ceramic (3DBC) scaffolds in the restoration of long bone defects. The objective of this study is to test the efficacy of the osteogenic agent dipyri-damole on 3DBC scaffold-mediated healing of calvarial defects using a sheep model. METHODS: Custom 3DBC scaffolds were either(More)
