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.

Radiological and clinical femoroacetabular impingement after slipped capital femoral epiphysis treated by in situ fixation.

Background: The treatment of slipped capital femoral epiphysis (SCFE) is always surgical. In situ fixation (ISF) is widely accepted to stop the epiphysis slipping. Femoroacetabular impingement (FAI) is recognized as a complication after ISF and is one of the major causes of early hip osteoarthritis.

Material And Methods: Over a period of 20 months patients with a knee MRI and the diagnosis of trochlear dysplasia were retrospectively included. Exclusion criteria were incomplete examination, qualitatively non-diagnostic examination, post trochlear surgery, missing informed consent for research purposes.

Validation of the French version of the Caregivers' Priorities and Child Health Index of Life with Disabilities questionnaire.

Introduction: The Caregivers' Priorities and Child Health Index of Life with Disabilities (CPCHILD) is a questionnaire that measures the health-related quality of life (HRQL) of children with cerebral palsy (CP). Though measuring HRQL is challenging in these children, it is a valuable help for medical decision-making. There is no questionnaire to assess HRQL in French-speaking children with severe CP.

Risk of repeated drainage in pediatric septic arthritis: patient or method?

How drainage of septic arthritis should be performed remains controversial. The aim of the present study was to compare arthrocentesis (Ac) using double intra-articular needle lavage to arthrotomy (At) as first-line drainage treatment for pediatric hip and knee septic arthritis. The secondary objective was to identify risk factors of second articular drainage.

Translation and validation of the French version of the adolescent idiopathic scoliosis Truncal Anterior Asymmetry Scoliosis Questionnaire (TAASQ).

A Randomized Trial of Intra-articular Injection Therapy for Knee Osteoarthritis.

Background: Intra-articular injections are widely used for conservative treatment of knee osteoarthritis (OA). However, rigorous data are lacking regarding the comparative therapeutic effectiveness of these injections.

Purpose: The aim of this study was to compare clinical outcomes after intra-articular injections of glucocorticoid, hyaluronic acid, platelet-rich plasma (PRP), or placebo in patients with mild or moderate OA of the knee.

Can pre-operative intraarticular injection predict pain relief after total hip arthroplasty?

Background: To study if pain relief after injection and arthroplasty correlate.

Methods: A retrospective cohort study included consecutive patients (n = 88; median age 64 (interquartile range (IQR) 22) years, 49 (56%) females) that received fluoroscopic-guided intra-articular hip injection with contrast agent, anaesthetic (diagnostic), and corticosteroid (therapeutic) before implantation of primary total hip arthroplasty. Pain scores were assessed pre-injection, post-injection after 15 min (diagnostic phase) at first clinical follow up (therapeutic phase; median 2 (IQR 2) months), and postoperatively (last follow up (median 15 (IQR 5) months)).

Elbow dislocation with and without an associated fracture in children: A prospective study of functional outcomes following 3 weeks of immobilization.

Introduction: The initial management of elbow dislocations in children, emergency reduction and brachial-antebrachial-palmar (BABP) immobilization, remains the most widely used method. Osteosynthesis could be associated in case of fractures. On the other hand, there is no consensus on the duration of immobilization in the recent literature.

Bone marrow edema of the medioplantar talar head is associated with severe ligamentous injury in ankle sprain.

Purpose: To investigate the predictive value of talar head edema (THE) in acute ankle sprain for the presence of concomitant ligament injuries.

Three-dimensional analysis for quantification of knee joint space width with weight-bearing CT: comparison with non-weight-bearing CT and weight-bearing radiography.

Objective: To compare computer-based 3D-analysis for quantification of the femorotibial joint space width (JSW) using weight-bearing cone beam CT (WB-CT), non-weight-bearing multi-detector CT (NWB-CT), and weight-bearing conventional radiographs (WB-XR).

Design: Twenty-six participants prospectively underwent NWB-CT, WB-CT, and WB-XR of the knee. For WB-CT and NWB-CT, the average and minimal JSW was quantified by 3D-analysis of the minimal distance of any point of the subchondral tibial bone surface and the femur.
