Diffusion-weighted MRI Reveals Epiphyseal and Metaphyseal Abnormalities in Legg-Calvé-Perthes Disease: A Pilot Study

Won Joon Yoo MD, Young-Jo Kim MD, PhD, Nina M. Menezes PhD, Jung-Eun Cheon MD, Diego Jaramillo MD, MPH

Legg-Calvé-Perthes disease (LCP) is thought to be associated with ischemic events in the femoral head. However, the types and patterns of reperfusion after these ischemic events are unclear.

Better Walking Performance in Older Children With Cerebral Palsy

Elisabet Rodby-Bousquet RPT, Gunnar Hägglund MD, PhD

Children with cerebral palsy (CP) often walk with a slower speed and a higher energy cost. Their walking performance and choice of mobility method may vary in different environments. Independent mobility is important for activity and participation.

Two Novel COL2A1 Mutations Associated with a Legg-Calvé-Perthes Disease-like Presentation

Peter Kannu MB, ChB, DCH, FRACP, Melita Irving MBBS, FRCP, Salim Aftimos MD, Ravi Savarirayan MBBS, FRACP

Abnormal development and growth of the capital femoral epiphysis and acetabulum are associated with a wide variety of underlying etiologies, one of which is Legg-Calvé-Perthes disease.

The Presence of an Ossific Nucleus Does Not Protect Against Osteonecrosis After Treatment of Developmental Dysplasia of the Hip

Andreas Roposch MD, MSc, FRCS, Odeh Odeh MB, BCh, Andrea S. Doria MD, MSc, PhD, John H. Wedge OC, MD, FRCSC

Osteonecrosis (ON) is a major complication after treatment of developmental dysplasia of the hip (DDH). Several studies have explored the absence of the femoral head ossific nucleus at the time of hip reduction as a risk factor for the development of ON, but findings have been inconsistent.

Pelvic Rotation and Tilt Can Cause Misinterpretation of the Acetabular Index Measured on Radiographs

M. J. Bom PhD, M. E. Groote MD, K. L. Vincken PhD, F. J. Beek PhD, L. W. Bartels PhD

Radiographic diagnosis and followup studies of developmental dysplasia of the hip are commonly performed by measuring the acetabular index on radiographs using Hilgenreiner’s method. The outcome of the measurement, however, depends on the orientation of the subject’s pelvis relative to the xray source. The influence of pelvic rotation and tilt on the measurement error has been evaluated separately but not in combination.

VEPTR™ Growing Rods for Early-onset Neuromuscular Scoliosis: Feasible and Effective

Klane K. White MD, MSc, Kit M. Song MD, MHA, Nathan Frost MD, Brian K. Daines MD

The Vertical Expandable Prosthetic Titanium Rib (VEPTR™; Synthes North America, West Chester, PA) reportedly controls spinal deformity associated with constrictive chest wall conditions.

Radical Posterior Capsulectomy Improves Sagittal Knee Motion in Crouch Gait

Todd C. Moen MD, Luciano Dias MD, Vineeta T. Swaroop MD, Nicholas Gryfakis MS, Claudia Kelp-Lenane PT

Knee flexion contracture leading to crouch gait is commonly seen in children with myelomeningocele. Progressive increase in knee flexion contracture increases energy cost, which interferes with efficient, functional ambulation. To prevent this, surgical release has been recommended when a knee flexion contracture exceeds 15° to 20°.

How Does Participation of Youth With Spina Bifida Vary by Age?

Erin H. Kelly PhD, Haluk Altiok MD, Julie A. Gorzkowski MSW, LSW, Jennifer R. Abrams MSW, LSW, Lawrence C. Vogel MD

Youth with disabilities are at risk for decreased participation in community activities. However, little is known about participation at different developmental periods of childhood and adolescence among youth with spina bifida (SB) or whether child, family, and SB-associated factors influence participation.
