Three-Dimensional Spinal Evaluation Using Rasterstereography in Patients with Adolescent Idiopathic Scoliosis: Is It Closer to Three-Dimensional or Two-Dimensional Radiography?

(1) Background: Adolescent Idiopathic Scoliosis (AIS) is a three-dimensional (3D) spine deformity. The Cobb angle, evaluated with 2D radiography, is the gold standard to determine curve severity. The primary aim of this study was to evaluate the 3D spinal evaluation with rasterstereography in patients with AIS.

Differential perivascular microglial activation in the deep white matter in vascular dementia developed post-stroke.

With the hypothesis that perivascular microglia are involved as neuroinflammatory components of the gliovascular unit contributing to white matter hyperintensities on MRI and pathophysiology, we assessed their status in stroke survivors who develop dementia. Immunohistochemical and immunofluorescent methods were used to assess the distribution and quantification of total and perivascular microglial cell densities in 68 brains focusing on the frontal lobe WM and overlying neocortex in post-stroke dementia (PSD), post-stroke non-dementia (PSND) and similar age control subjects. We primarily used CD68 as a marker of phagocytic microglia, as well as other markers of microglia including Iba-1 and TMEM119, and the myeloid cell marker TREM2 to assess dementia-specific changes.

Minimally Invasive Versus Standard Surgery in Idiopathic Scoliosis Patients: A Comparative Study.

Study Design: Retrospective review of prospective case-control study.

Objective: To compare minimally invasive scoliosis surgery (MIS) and posterior spinal fusion (PSF) in a large group of patients.

Summary Of Background Data: MIS, has been shown to have benefits over standard PSF in adolescent idiopathic scoliosis (AIS).

Clinical and radiological outcomes of minimally-invasive surgery for adolescent idiopathic scoliosis at a minimum two years' follow-up.

Aims: The direct posterior approach with subperiosteal dissection of the paraspinal muscles from the vertebrae is considered to be the standard approach for the surgical treatment of adolescent idiopathic scoliosis (AIS). We investigated whether or not a minimally-invasive surgery (MIS) technique could offer improved results.

Methods: Consecutive AIS patients treated with an MIS technique at two tertiary centres from June 2013 to March 2016 were retrospectively included.

Minimally invasive surgery for adolescent idiopathic scoliosis: correction of deformity and peri-operative morbidity in 70 consecutive patients.

Aims: The aim of this study was to report a retrospective, consecutive series of patients with adolescent idiopathic scoliosis (AIS) who were treated with posterior minimally invasive surgery (MIS) with a mean follow-up of two years (sd 1.4; 0.9 to 0 3.

[Adolescent idiopathic scoliosis : diagnostic criteria and management].

The rapid growth of the spine during the pubertal spurt requires greater vigilance for the pediatrician at the annual check during this period to detect the occurrence of scoliosis. Before confirming the diagnosis of idiopathic scoliosis, it is imperative to exclude a secondary cause with appropriate history and clinical examination, and in selective cases with additional testing. Any scoliosis detected during growth should be considered potentially progressive and sent to a specialist if it is equal to or exceeds 20° on the X-rays.

Obturator externus abscess in a 9-year-old child: A case report and literature review.

Rationale: Obturator pyomyositis is a rare condition in children. Diagnosis is often delayed because of its rarity, and the vagaries of its presentation cause it to be easily be missed. Physicians should therefore familiarize themselves with this condition and consider it as a possible differential diagnosis in patients presenting with an acutely painful hip.

Arthroscopic treatment of septic arthritis of the knee in children.

Introduction: Childhood septic arthritis of the knee is a serious disease that can impair growth and cause serious functional sequelae. There are few data on arthroscopic treatment in children, and series were always less than 20 cases.

Hypothesis: The objective of this study was to assess clinical and radiographic results of arthroscopic drainage combined with antibiotic therapy for the treatment of childhood septic arthritis of the knee.

Aluminum and iron can be deposited in the calcified matrix of bone exostoses.

Exostosis (or osteochondroma) is the most common benign bone tumor encountered in children and adults. Exostoses may occur as solitary or multiple tumors (in the autosomal syndromes of hereditary multiple exostoses). Exostoses are composed of cortical and medullary bone covered by an overlying hyaline cartilage cap.

The progression of lumbar curves in adolescent Lenke 1 scoliosis and the distal adding-on phenomenon.

Introduction: The postoperative deterioration of the curve below spinal fusion instrumentation resulting in a distal adding-on (AO) phenomenon in idiopathic adolescent scoliosis (IAS) frequently requires surgical revision with disappointing secondary clinical results.

Hypothesis: Analysis of AP (coronal) range of motion (cROM) and lateral (sagittal) range of motion (sROM) on dynamic (side-bending, flexion, extension) X-rays to determine the choice of the lowest instrumented vertebra (LIV) can help reduce distal adding-on. The goal of this study was to study the postoperative progression of the lumbar curve in Lenke 1 scoliosis operated on with a LIV based on dynamic X-ray results.

Lumbo-sacral motion conserved after isthmic reconstruction: long-term results.

Purpose: The purpose of this study was to analyze the clinical and radiological results of repair of the interarticularis pars defect by a modified Buck's repair technique in patients with symptomatic spondylolysis with grade 1 spondylolisthesis. These patients with painful spondylolisthesis are the most eligible for direct repair of the defect rather than lumbo-sacral fusion in an attempt to save motion segments.

Methods: Forty-six patients with symptomatic spondylolysis with grade 1 spondylolisthesis and normal L4-L5 and L5-S1 disks, following the failure of conservative treatment, underwent surgery between 1988 and 2010.

Lumbosacral arthrodesis for neuromuscular scoliosis using a simplified Jackson technique.

Unlabelled: Treating patients with severe neuromuscular scoliosis by long spinal fusion improves their quality of life and provides significant comfort for the patient and caregivers. But lumbosacral (L5-S1) fusion is challenging in these patients because of the significant deformities that result in poor bone anchoring quality and a risk of impingement between the skin and implants. In 1993, Jackson described a L5-S1 fusion technique using S1 pedicle screws and intrasacral rods (implanted under X-ray guidance) that are linked to the construct above with connectors.

The arthritic wrist. II--the degenerative wrist: indications for different surgical treatments.

For the patient (and the surgeon) the ideal wrist is one that has good mobility, however very often the optimal surgical treatment is one that provides effective pain relief. The patient must be informed of the potential complications and limitations of each procedure. The patient's psychological profile and functional requirements will determine how well he/she adapts to the changes.

The arthritic wrist. I--the degenerative wrist: surgical treatment approaches.

Unlabelled: The primary goal in treating a degenerative wrist is to provide pain relief, while maintaining strength and mobility if possible. After failure of the recommended conservative treatment, the choice of approaches can be made from a large collection of techniques, some which are well validated. Partial wrist fusion, particularly the Watson procedure, results in a pain-free wrist in 80% of cases, with 50% of the mobility preserved, good grasping strength and stable results for at least 10 years.

[Priapism: a severe paediatric complication of Fabry disease].

Fabry disease is an X-linked recessive lysosomal storage disorder caused by α-galactosidase A deficiency. Although the disease presents in childhood, diagnosis is often delayed to adulthood or missed, presumably due to the lack of specificity of the symptoms and to the absence of major complication during the paediatric years. We report a 9-year-old boy known to have a Fabry disease who presented an episode of priapism.
