Hanle-effect observations of forbidden coronal line transitions and recently also longitudinal Zeeman-effect measurements of coronal lines show quantitative signatures of the weak coronal magnetic field. The interpretation of these observations is, however, complicated by the fact that they are the result of line-of-sight integrations through the optically thin corona. We study by means of simu...

Consecutive coronal CT scans of the paranasal sinus and radiologic medical records of patients examined at Wilford Hall USAF Medical Center from July 1987 through December 1988 were reviewed for the presence of pneumatization of the uncinate process. Patients with previous alteration of the anatomy of the paranasal sinus due to facial trauma, carcinoma of the paranasal sinus , inverted papillom...

A person with amputation's subjective perception is the only tool available to describe fit and comfort to a prosthetist. However, few studies have investigated the effect of alignment on this perception. The aim of this article is to determine whether people with amputation could perceive the alignment perturbations of their prostheses and effectively communicate them. A randomized controlled ...

Advancements in total ankle arthroplasty (TAA) over the past several decades have led to improved patient outcomes and implant survivorship. Despite these innovations, many implant manufacturers still consider a preoperative coronal plane deformity greater than 10° a relative contraindication to TAA. Without proper intraoperative alignment, these implants may experience abnormal wear and hardwa...

The goal of this study was to identify supracondylar fracture patterns that were predictive of adverse events and poor outcomes. The study consisted of a retrospective review of patients admitted for surgical treatment of a supracondylar humerus fracture between June 2008 and August 2010. Preoperative radiographs were assessed based on appearance (simple vs oblique vs comminuted), coronal plane...

STUDY DESIGN Retrospective, case-control, matched cohort. OBJECTIVE Compare the radiographic and clinical outcomes of adult spinal deformity patients treated with thoracic pedicle screw (TPS) or thoracic hook constructs. SUMMARY OF BACKGROUND DATA The efficacy of TPS instrumentation for pediatric spinal deformity correction has been established. Little is known about TPS use in adult spinal...

MR images of the fetus allow non-invasive analysis of the fetal brain. Quantitative analysis of fetal brain development requires automatic brain tissue segmentation that is typically preceded by segmentation of the intracranial volume (ICV). This is challenging because fetal MR images visualize the whole moving fetus and in addition partially visualize the maternal body. This paper presents an ...

BACKGROUND Many patients with X-linked hypophosphataemic rickets (X-LHPR) demonstrate significant lower limb deformity despite optimal medical management. This study evaluates the use of guided growth by means of hemi-epiphysiodesis to address coronal plane deformity in the skeletally immature child. METHODS Since 2005, 24 patients with X-LHPR have been referred to our orthopaedic unit for ev...

Dear Editor,We have greatly enjoyed reading the case report entitled “‘Femoral Condyle Fracture during Revision of Anterior Cruciate Ligament Reconstruction: Case Report and a Review of Literature in the issue of Arch Bone Jt Surg. 2015;3(2) with great interest. We would like to commend the authors for their detailed and valuable work. Although various case reports have described postoperative ...

BACKGROUND High tension in an anterior cruciate ligament graft adversely affects both the graft and the knee; however, it is unknown why high graft tension in flexion occurs in association with a posterior femoral tunnel. The purpose of the present study was to determine the effect of the angle of the femoral and tibial tunnels in the coronal plane and incremental excision of the posterior cruc...
