Prevalence of Femoroacetabular Impingement Morphology in Asymptomatic Adolescents.

Background: Femoroacetabular impingement (FAI) can lead to acetabular chondrolabral damage and has been theorized as a causative factor in the development of osteoarthritis. The pathogenesis of FAI is unknown. The purpose of this study was to determine the prevalence of FAI morphology in asymptomatic adolescents.

Comparison of Effective Dose of Radiation During Pedicle Screw Placement Using Intraoperative Computed Tomography Navigation Versus Fluoroscopy in Children With Spinal Deformities.

Background: We compared the effective dose of radiation associated with pedicle screw placement in posterior spinal fusion in children using intraoperative computed tomography (CT) navigation versus intraoperative fluoroscopy (C-arm).

Methods: In this review of posterior spinal fusion patients, height, weight, local density function, dose area product, body region, number of views, and part of the body were used to calculate the effective dose to the patient in millisieverts (mSv) in 37 children in whom pedicle screw placement was aided by intraoperative CT versus 44 children in whom pedicle screw placement was aided by C-arm. Both groups had posterior spinal fusions during the same time period by 3 surgeons between November 2012 and August 2013.

Vitamin D Deficiency in Children Undergoing Vertical Expandable Prosthetic Titanium Rib Treatment.

Background: Vitamin D deficiency is prevalent in the pediatric population and multiple risk factors have been identified. Low vitamin D levels can result in poor bone mineralization and have been associated with a significantly higher risk of forearm fracture in children. Vitamin D deficiency has also been associated with pediatric critical illness.

Congenital scoliosis SRS-22 outcomes in children treated with observation, surgery, and VEPTR.

Study Design: Prospective, nonrandomized study of children with congenital scoliosis.

Objective: To determine the outcomes of children with congenital scoliosis using SRS-22.

Summary Of Background Data: Outcome measures in children with congenital scoliosis are unreported.

Osteochondromas after radiation for pediatric malignancies: a role for expanded counseling for skeletal side effects.

Background: A relationship has been reported between total body irradiation (TBI) and later development of osteochondromas in children who receive radiation therapy as conditioning before hematopoietic stem cell transplantation (HSCT). The goal of this study was to better characterize osteochondromas occurring in these children.

Methods: We identified all children (0 to 18 y) who received an allogeneic HSCT and TBI from 2000 to 2012 from a blood and marrow transplant (BMT) database.
