Methods for three-dimensional characterization of the acetabulum prior to pelvic reorientation osteotomy: a scoping review.

Periacetabular osteotomy is the gold standard treatment for acetabular dysplasia. The great variability of acetabular dysplasia requires a personalized preoperative planning improved by 3D reconstruction and computer-assisted surgery. To plan the displacement of the acetabular fragment by a pelvic osteotomy, it is necessary to define a reference plane and a method to characterize 3D acetabular orientation.

Frequency and management of rod fractures following minimally invasive bipolar fusionless surgery in neuromuscular scoliosis patients.

Introduction: Neuromuscular scoliosis (NMS) is associated with an abnormal muscle tone. Traditional conservative treatments, with the historical practice of early posterior fusion, have proven ineffective. Recently, growth-sparing techniques have gained traction owing to their ability to maximize trunk height.

3D pre-operative planning and patient-specific guides for re-directional peri-acetabular osteotomy in children and adolescents.

Surgical procedures to correct hip dysplasia associated with subluxation or dislocation of the femoral head are complex. The 3D geometric abnormalities of the acetabulum and proximal femur vary across patients. We, therefore, suggest a patient-specific surgical treatment involving computer-assisted 3D planning of the peri-acetabular osteotomies, taking into account the femoral head position; 3D printing of patient-specific guides for the cuts, repositioning, and fixation; and intra-operative application of the simulated displacements with their fixation.

Effect of an augmented reality active video game for gait training in children with cerebral palsy following single-event multilevel surgery: protocol for a randomised controlled trial.

Introduction: In paediatric rehabilitation, fun and motivation are also critical keys to successful therapy. A variety of interventions have shown positive effects, high level of interest, compliance and engagement with active video game (AVG).This seems to be an interesting approach for the postoperative gait rehabilitation of children with cerebral palsy (CP).

Long-term outcomes of hip reconstruction surgery in children with GMFCS III diplegic cerebral palsy.

Introduction: The results of hip reconstruction surgery are known for non-walking (GMFCS IV and V) and walking (GMFCS I and II) patients. Few studies deal with GMFCS III patients in isolation. Their intermediate functional status can be deteriorated by asymmetrical contractures, hip dislocation, multi-level deformities of the lower limbs, leading to motor function degradation, and possibly losing their ability to walk.

Long-term outcomes of ilio-sacral screws in minimally invasive bipolar fusionless technique for neuromuscular scoliosis: a retrospective study in 167 patients.

Introduction: Pelvic fixation in patients with neuromuscular scoliosis is difficult, due to their fragile general condition and poor bone quality. Many techniques have been described, associated with high rates of mechanical complications. The objective of this work was to evaluate the mechanical complications and long-term radiological results of ilio-sacral screw pelvic fixation.

Rehabilitation After Single-Event Multilevel Surgery for Children and Young Adults With Cerebral Palsy: A Systematic Review.

This review sought to describe and analyze published protocols for rehabilitation after single-event multilevel surgery for people with cerebral palsy, to identify their differences and limits, and to introduce a common step-by-step framework for future descriptions and assessments of postoperative rehabilitation protocols.The MEDLINE, Embase, CINAHL, and the Cochrane Library databases were searched. Inclusion criteria were as follows: (1) single-event multilevel surgery, (2) full-text reports published after 1985, and (3) articles with a method section describing the rehabilitation protocol.

Clinical gait analysis and physical examination don't correlate with physical activity of children with cerebral palsy. Cross-sectional study.

Gait analysis and physical clinical measures are usually performed in children with cerebral palsy to help the surgeons make therapeutic decision. However, the level of physical activity in daily life is not systematically assessed. The aim of this cross sectional study was to examine the correlations between: three-dimensional gait analysis kinematic and spatiotemporal parameters, clinical measures and physical activity.

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.

One-way self-expanding rod for early-onset scoliosis: early results of a clinical trial of 20 patients.

Purpose: Progressive early-onset scoliosis raises major challenges for surgeons, as growth must be preserved. With traditional growing rods, the need for repeated surgery is associated with numerous complications, high costs, and heavy psychosocial burden on the patient and family. We assessed the safety and efficacy of a new one-way self-expanding rod (OWSER).

Medium-term results of calcaneus lengthening in idiopathic symptomatic flat foot in children and adolescents.

Purpose: Calcaneus lengthening can be used in symptomatic flat foot in children, but few details on its medium-term results and complementary procedures are available.

Methods: A total of 20 flexible, symptomatic, idiopathic valgus flat feet (in 15 children; mean age 13.9 years (10 to 17)) were operated on.

Kinematics after unilateral femoral derotation osteotomy in children with diplegic cerebral palsy.

Introduction: Femoral derotation osteotomy (FDO) is a treatment option in children and adolescents with cerebral palsy who have transverse plane deviations in their lower limbs. When the transverse kinematic deviations are asymmetric, the osteotomy indication can be unilateral.

Hypothesis: Unilateral FDO has a kinematic effect on ipsilateral transverse plane deviations along with those of the pelvis and contralateral side.

Long term results of the revisited Meary closing wedge tarsectomy for the treatment of the fixed cavo-varus foot in adolescent with Charcot-Marie-Tooth disease.

Background: Various techniques have been proposed for the treatment of cavovarus feet (CVF). The aim of this study was to report outcomes of the revisited Meary's dorsal closing wedge tarsectomy for fixed CVF secondary to Charcot-Marie-Tooth (CMT) disease.

Methods: All CVF operated on between 1977 and 2011 were included.

Surgical treatment of idiopathic pes planovalgus in paediatric patients.

Idiopathic pes planus is common and usually physiologic. Decompensation, when it occurs, may be obvious or on the contrary difficult to identify, raising challenges in patient selection for surgical treatment. The physical examination of a child with pes planus must include an evaluation in the supine position, which helps to adjust the amount of correction during surgery.

Minimally Invasive Surgery for Neuromuscular Scoliosis: Results and Complications in a Series of One Hundred Patients.

Study Design: A retrospective review.

Objective: To report the results of an alternative technique using a minimally invasive fusionless surgery. The originality is based on the progressive correction of the deformities with proximal and distal fixation and on the reliability of the pelvic fixation using iliosacral screws on osteoporotic bones.

Predicting postoperative gait in cerebral palsy.

In this work, postoperative lower limb kinematics are predicted with respect to preoperative kinematics, physical examination and surgery data. Data of 115 children with cerebral palsy that have undergone single-event multilevel surgery were considered. Preoperative data dimension was reduced utilizing principal component analysis.

Rectus femoris transfer and musculo-skeletal modeling: effect of surgical treatment on gait and on rectus femoris kinematics.

Spasticity of the rectus femoris (RF) is one of the possible causes of stiff knee gait (SKG) in cerebral palsy. Musculoskeletal studies have shown that in SKG, length and speed of the RF are affected. No evaluation had been made to quantify the modifications of those parameters after surgery.

Proximal femoral osteotomy in neurologic pediatric hips using the locking compression plate.

Background: Proximal femoral osteotomy (PFO) is a widely performed reconstructive surgery in pediatric patients with diagnosis of neurologic abnormalities. Many implants have been used for the fixation of these osteotomies. These devices have been evolved to provide stable fixation.

The convex wrapping algorithm: a method for identifying muscle paths using the underlying bone mesh.

Associating musculoskeletal models to motion analysis data enables the determination of the muscular lengths, lengthening rates and moment arms of the muscles during the studied movement. Therefore, those models must be anatomically personalized and able to identify realistic muscular paths. Different kinds of algorithms exist to achieve this last issue, such as the wired models and the finite elements ones.

Purpose: The results of a prospective series of 62 patients treated for neuromuscular spinal deformities with spinopelvic fixation using iliosacral screws are presented and discussed.

Methods: Sixty-two consecutive patients diagnosed with neuromuscular disorders were prospectively included. Pelvic obliquity and other angular parameters were measured.

Sacral and lumbar-pelvic morphology in high-grade spondylolisthesis.

Numerous authors have stressed the importance of posterior arch, vertebral bodies, and intervertebral disk dysplastic changes in lumbosacral spondylolisthesis. An extensive morphologic analysis was conducted of the lumbosacral junction in a series of 100 consecutive patients presenting with severe lumbosacral spondylolisthesis. Statistical correlations were found between the pelvic incidence, sacral slope, and pelvic tilt, as found in healthy volunteers.

Lumbar hyperlordosis of neuromuscular origin: pathophysiology and surgical strategy for correction.

Lumbar hyperlordosis of neuromuscular origin is rare and requires surgical treatment in order to preserve a good sitting posture. We report twenty-seven cases of a preponderantly sagittal hyperlordosis deformity of the lumbar spine in patients with neuromuscular disorders and identify the indications and results of treatment. Seventeen males and ten females, aged 13 to 27 years, underwent operations for a lumbar hyperlordosis of neuromuscular origin responsible for major difficulties in sitting.
