Non-operative treatment of adolescent idiopathic scoliosis.

Adolescent idiopathic scoliosis worsens mainly during growth at puberty. This is when non-operative treatment, by brace and physiotherapy, comes into its own. Only the brace has proven efficacy in stabilizing Cobb's angle.

Early Intensive Bimanual Stimulation Program (BB-Bim) for Infants at Risk of Unilateral Cerebral Palsy: A Randomized, Multiple-Baseline, Single-Case Study.

Importance: Clinical practice guidelines for infants at high risk of cerebral palsy (CP) emphasize the importance of very early and intensive intervention.

Objective: To determine the feasibility of a new, home-based, early intensive bimanual stimulation program (BB-Bim) and its impact on hand function in infants at risk of unilateral CP.

Design: Single case experimental design, multiple baseline across subjects, lasting from 12 to 15 wk, including a 4- to 7-wk randomized baseline, followed by 8 wk of BB-Bim.

Retrospective study of functional benefits and satisfaction in multisite upper-limb surgery in children with unilateral cerebral palsy.

Objectives: To evaluate the functional impact of individualised multisite neuro-orthopedic upper-limb surgery in children with unilateral cerebral palsy, and to assess patient satisfaction.

Patients And Methods: This retrospective study evaluated the impact of surgery on unilateral functional capacity on the Melbourne Assessment (MA2) and Box and Blocks test, on bimanual performance on the Assisting Hand Assessment, and on achievement of individualised goals. Satisfaction was assessed on a Likert scale between 6 and 14 months after surgery.

Does accelerometry reflect hand function in infants at risk of unilateral cerebral palsy? A secondary analysis of BB-Bim results.

Background: Infants at high-risk of unilateral Cerebral Palsy (UCP) may have asymmetry in upper extremity movement and function, which should be identified as soon as possible for management.

Aims: To explore the feasibility of using two AX3 Axivity monitors in wrist-worn bracelets to quantify movements, and to identify whether accelerometry parameters are consistent with hand function.

Methods And Procedures: 6 infants at high risk of UCP (aged 3 to -12 months) were included in a Single-Case Experimental Design to explore the impact of an 8-week bimanual stimulation home program.

Influence of the thoracolumbar junction flexibility on the risk of adding-on after posterior vertebral arthrodesis for thoracic idiopathic adolescent scoliosis.

Purpose: The objective was to analyze the role of the thoracolumbar sagittal flexibility on the outcome after posterior spinal fusion of Lenke 1 and 2 adolescent idiopathic scoliosis with last touched vertebra as the lowest instrumented vertebra.

Methods: We included 105 thoracic AIS patients who had a posterior spinal fusion with a 2 years minimum follow-up. Thoracolumbar junction flexibility was assessed on dynamic sagittal X-rays and compared to the standing position.

It is time to define an organizational model for the prevention and management of infections along the surgical pathway: a worldwide cross-sectional survey.

Background: The objectives of the study were to investigate the organizational characteristics of acute care facilities worldwide in preventing and managing infections in surgery; assess participants' perception regarding infection prevention and control (IPC) measures, antibiotic prescribing practices, and source control; describe awareness about the global burden of antimicrobial resistance (AMR) and IPC measures; and determine the role of the Coronavirus Disease 2019 pandemic on said awareness.

Methods: A cross-sectional web-based survey was conducted contacting 1432 health care workers (HCWs) belonging to a mailing list provided by the Global Alliance for Infections in Surgery. The self-administered questionnaire was developed by a multidisciplinary team.

[COVID-19: On the verge of madness].

Disorganizations due to the current coronavirus SARS-CoV-2 pandemic that have required a national quarantine from the 17th of march to the 11 of May 2020, mangle and question. In view of the situation's extreme traumatic character and of the pathological consequences observed, we are going to try to give meaning to an almost chaotic situation. Our shared production, coming out of two psychologists - one being in quarantine and the other one not - crossed diary trying to put the theory in favor of the clinic, has for aim to build a support structuring thought.

Survival and complications in hinged knee reconstruction prostheses after distal femoral or proximal tibial tumor resection: A retrospective study of 161 cases.

Introduction: Hinged knee megaprostheses are mainly used for reconstruction after tumor resection. They may incur complications, but this has not been assessed in the French literature, except in small series at short follow-up. We therefore conducted a large-scale nationwide multicenter retrospective study with a minimum 5 years' follow-up.

Revision after spinal stenosis surgery.

Purpose: To make a literature review on spinal stenosis recurrence after a first surgery and edit rules to avoid this complication.

Methods: We conducted two separate PUBMED searches to evaluate the revision post-stenosis and degenerative scoliosis surgery using the terms: lumbar vertebrae/surgery, spinal stenosis, spine, scoliosis and reoperation. The resulting papers were categorized into three groups: (1) those that evaluated reoperation post-simple decompression; (2) those that evaluated spinal decompression and fusion for short (3 levels or less) or long (more than 3 levels) segment spinal fusion; and (3) those diagnosing the stenosis during the surgery.

The use of a photogrammetric method for the three-dimensional evaluation of spinal correction in scoliosis.

Purpose: Clinical parameters, characterizing the spinal deformations due to scoliosis, are still directly measured on the spinal curve plane projections.

Methods: A 3D spinal curve has been reconstructed from its two projections, using photogrammetric techniques. Each spinal curve is a compound of several plane regions, where it is purely flexed, and short zones of connection, where abduction and axial rotation components are concentrated.

Sagittal balance analysis after pedicle subtraction osteotomy in ankylosing spondylitis.

Introduction: This is a radiographic study of ankylosing spondylitis patients with severe fixed kyphotic deformity who underwent pedicle subtraction osteotomy. Our goal was to measure and validate new angle to assess global kyphosis and to evaluate the sagittal balance after surgery. This is the first report which describes new angle to assess global kyphosis (T1-S1).

Radiological analysis of ankylosing spondylitis patients with severe kyphosis before and after pedicle subtraction osteotomy.

This is a radiographic study of ankylosing spondylitis patients with severe fixed kyphotic deformity who underwent pedicle subtraction osteotomy. Our goal was to measure and validate new angle to assess global kyphosis and to evaluate the radiological outcomes after surgery. This is the first report which describes new angle to assess global kyphosis (T1-S1).

Analysis of structural features of deformed spines in frontal and sagittal projections.

In the study of spine, two approaches exist. Clinicians still measure directly, either on X-ray films or on digitized images, a small number of angular values characterizing the profile of deformed spines. 3D software programs exist, but they describe the spinal features calculated from a large set number of inputs.

Sagittal alignment of the spine and pelvis in the presence of L5-s1 isthmic lysis and low-grade spondylolisthesis.
