Foot growth disorder after surgery of lower limb malignant bone tumor in a pediatric series.

Bakground: Child malignant bone tumors often develop near growth cartilage. The gold standard surgery consists in large segmental resection. This resection often requires the sacrifice of growth cartilage, leading to inequality of limb length.

Pregnancy and childbirth after adolescent idiopathic scoliosis surgery: A study of 80 pregnancies.

Background: Adolescent idiopathic scoliosis (AIS) is a common spinal disease affecting 2% of adolescents, and women in 90% of the cases. When a surgical treatment is opted for, many questions are frequently asked by families and patients about the course of pregnancy and childbirth after the spinal fusion. This subject remains little studied in the literature, especially with modern instrumentation techniques.

Surgical Treatment of Juvenile Idiopathic Arthritis in the Era of Novel Drug Therapies.

Juvenile idiopathic arthritis is the most common chronic rheumatic disease encountered in children under the age of sixteen and causes significant impairments in daily life. Over the last two decades, the introduction of new drug treatments (including disease-modifying antirheumatic drugs and biologics) has changed the course of this disease, thus reducing the indication for surgery. However, some patients fail to respond to drug therapy and thus require personalized surgical management, e.

Surgical outcomes of spinal osteochondroma in children: A multicentre observational study.

Background: Spinal osteochondroma (or exostosis) is a rare benign tumour whose clinical manifestations are delayed due to their slow growth and location. Few studies have addressed the characteristics and the diagnostic and therapeutic peculiarities of spinal osteochondroma in children. The objective of this multicentre observational study was to assess the outcomes of a cohort of children after surgery for spinal osteochondroma.

Summary Of Background Data: Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine that may require surgical correction.

High-grade L5-S1 spondylolisthesis with lumbosacral kyphosis: Long-term results of non-instrumented circumferential arthrodesis in children, adolescents.

Introduction: The choice of surgical technique for high-grade spondylolisthesis (HGS) associated with lumbosacral kyphosis remains controversial. Are non-instrumented techniques still relevant, what with the multiplicity and modernity of patient-specific instrumentation?

Hypothesis: Our hypothesis was that a non-instrumented circumferential arthrodesis performed after a period of gradual reduction of HGS, associated with lumbosacral kyphosis, provided satisfactory long-term functional and radiographic results in children and adolescents while minimizing the risk of complications.

Materials And Methods: Thirty-one L5-S1 HGS associated with a lumbosacral kyphosis operated by non-instrumented circumferential arthrodesis after a period of traction and suspension were included in our study.

Optimal ilio-sacral screw trajectory in paediatric patients : a computed tomography study.

Pelvic fixation during procedures performed to treat spinal deformities in paediatric patients remains challenging. No computed tomography studies in paediatric have assessed the optimal trajectory of ilio- sacral screws to prevent screw malposition. We used pelvic computed tomography from 80 children divided into four groups : females <10 and ≥10 years and males <10 and ≥10 years.

Minimally Invasive Fusionless Surgery for Scoliosis in Spinal Muscular Atrophy: Long-term Follow-up Results in a Series of 59 Patients.

Background: Treatment of spinal muscular atrophy (SMA) scoliosis has evolved in the last decade, with the emergence of fusionless surgical techniques that allow correction of the deformity before the end of growth spurt. These techniques are expected to delay definitive spine fusion and preserve trunk growth.

Purpose: The aim was to evaluate long-term clinical, radiologic, and respiratory outcomes of a minimally invasive fusionless surgery (MIFLS) in SMA scoliosis.

Minimally Invasive Surgery for Neuromuscular Scoliosis: Results and Complications at a Minimal Follow-up of 5 Years.

Study Design: A prospective study.

Objective: The aim of this study was to report the results of an alternative technique to growing rods (GR) for neuromuscular scoliosis using a minimally invasive fusionless surgery with a minimum of 5 years' follow-up.

Summary Of Background Data: Conservative treatment is not effective in progressive neuromuscular scoliosis.

Well though-out introduction of percutaneous Achilles tenotomy during functional treatment of congenital talipes equinovarus: Which indications produce the best results?

Introduction: Percutaneous Achilles tenotomy (PAT) was recently added to functional treatment of congenital talipes equinovarus (aka clubfoot). The aim of this study was to determine the relevance of a carefully chosen radiological criterion for the PAT indication and to evaluate its results.

Hypothesis: When the tibiocalcaneal angle (aTiCa) is larger than 75° at 4 months, doing PAT will improve the results of the functional method in the medium term and will reduce the surgery rate.

'In-Out-In' K-wires sliding in severe tibial deformities of osteogenesis imperfecta: a technical note.

Severe infant osteogenesis imperfecta requires osteosynthesis. Intramedullary tibia's osteosynthesis is a technical challenge given the deformity and the medullar canal's narrowness. We describe an extramedullary technique: 'In-Out-In' K-wires sliding.

Long-term outcomes of non-invasive expandable endoprostheses for primary malignant tumors around the knee in skeletally-immature patients.

Introduction: Expandable endoprostheses are used to restore limb function and compensate for the sacrifice physis involved in carcinologic resection. Long-term outcomes of the last generation of knee "non-invasive" expandable endoprostheses are required. Objectives were to report on oncologic results of bone sarcoma resection around the knee with expandable endoprosthesis reconstruction and to compare the surgical outcomes of the "non-invasive" expandable endoprostheses used in our department.

Can Chiari Osteotomy Favorably Influence Long-term Hip Degradation in Multiple Epiphyseal Dysplasia and Pseudoachondroplasia?

Background: Multiple epiphyseal dysplasia (MED) and pseudoachondroplasia (PSACH) are congenital skeletal disorders characterized by irregular epiphyses, mild or severe short stature and early-onset osteoarthritis which frequently affect the hips. The current study evaluates the long-term results of the Chiari osteotomy in MED and PSACH patients.

Methods: Twenty patients (14 MED and 6 PSACH) were retrospectively included.

Epidemiology of spinal fractures in children: Cross-sectional study.

Introduction: Epidemiological studies of fractures of the spine in children are all old, mostly single-centre, with series spanning periods of 5 to 20 years.

Hypothesis: As lifestyle is constantly changing, notably with an increase in sports activities and improvements in the prevention of road and household accidents, epidemiology has likely changed.

Outcomes of growing rods in a series of early-onset scoliosis patients with neurofibromatosis type 1.

Objective: Early-onset scoliosis (EOS) is not uncommon in patients with neurofibromatosis type 1 (NF1). Despite conservative treatment, spinal deformities progress and require early surgical intervention. To avoid potential interference with chest and trunk growth, growing rods (GRs) have been used effectively in EOS of various etiologies.

Multidisciplinary surgical strategy for dumbbell neuroblastoma: A single-center experience of 32 cases.

Introduction: Prognosis of dumbbell neuroblastoma (NBL) is mainly determined by the sequelae induced by the tumor itself and the neurosurgical approach. However, after primary chemotherapy, surgical management of the residual tumor, especially the spinal canal component, remains controversial.

Methods: We conducted a single-center retrospective cohort study over the last 15 years (2002-2017) including patients treated for NBL with spinal canal extension focusing on timing and type of surgery, complications, and functional and oncological follow-up.
