“…This is especially true for the overall trunk balance parameters. We also found asymmetry in the transverse plane, with the trunk generally turned to the left, as previously reported in the literature [1,14,15]. This asymmetry in the transverse plane is more pronounced in patients with idiopathic scoliosis and is likely one of the specific features of patients with the disorder.…”

“…One of the advantages of motion analysis is that it can capture dynamic information (during walking) while also being able to capture static information, comparable to radiographic analysis [13]. With motion analysis, several authors have reported abnormal gait patterns in patients with idiopathic scoliosis; in particular, the trunk is turned to the left during the entire gait cycle [14][15][16]. This casts doubt on the analysis of overall trunk alignment performed on radiographs.…”

Adolescent idiopathic scoliosis is common condition in pediatric orthopedics that is generally analyzed with standard radiographs. However, the conditions under which the radiographs are made are completely different than the position that patients use during day-to-day activities. We hypothesized that the trunk's static position differs from its dynamic one. The aim of this study was to determine differences between the trunk's static and dynamic positions using motion analysis in adolescents with idiopathic scoliosis. Patients and methods: This prospective, single-center study enrolled adolescents with idiopathic scoliosis who were scheduled to undergo surgical correction. The day before the surgery, radiographs were made and motion analysis was performed (static and dynamic acquisitions). Various parameters were measured on the radiographs and motion analysis, including the coronal vertical axis (CVA), sagittal vertical axis (SVA) and coronal shoulder tilt. Results: The study enrolled 62 patients with a mean age of 15.5 years. There was a significant correlation between the radiographic measurements and the static motion analysis results for most parameters. Conversely, dynamic measurements of CVA, SVA and coronal shoulder tilt were not correlated to their static measurements (R = 0.229; 0.198 and −0.109 respectively, all p > 0.05). The static coronal shoulder tilt was opposite to the one found during walking (−0.9 • vs. 0.5 • , p = 0.031). Discussion: Our study is the first to compare the trunk's static position with its dynamic position during walking in a cohort of adolescents with idiopathic scoliosis. Motion analysis provides new information about the trunk's dynamic positions. Based on our findings, radiographic analysis only partially captures the spinal alignment and cannot be used to draw reliable conclusions about the trunk's dynamic balance.

“…In the last decades, gait patterns of patients with adolescent idiopathic scoliosis (AIS) have been extensively studied, resulting in various conclusions [17]. Most authors agreed that AIS altered postural body parameters, such as ground reaction forces, temporal-distance parameters, kinetics and kinematics of the lower extremities [18][19][20][21][22][23]. Recently, trunk motion in relation to pelvic positioning has been analyzed in AIS, showing adjustments and changes of the trunk, pelvis and lower extremities in severe thoracic AIS [17,[23][24][25].…”

“…Whereas changes in both nonoperated and surgically-treated AIS patients have been extensively studied [17][18][19][20][21][22][23][24][25], to our knowledge, no data are available studying gait patterns in young children with bilateral growthfriendly implants fixated between cranial ribs and the iliac rim. As expected in this patients' group, limited trunk movement could be found most likely due to additional stiffness both from bilateral implants and rigid scoliotic curves.…”

In young children, growth-friendly spinal implants with bilateral rib to pelvis fixation are used to control progressive spinal deformity. Whereas curve progression, complications and side-effects have been extensively studied in this patient population, no data are available on gait pattern changes and postural body adjustments. Our study evaluates whether gait pattern changed for ambulatory children treated with bilateral rib to pelvis implants compared to age-matched healthy children. In this small cohort study, gait analysis was performed using spatiotemporal and kinematic parameters of four ambulatory children with severe scoliosis and growthfriendly spinal implants using the bilateral rib to pelvis fixation. Data were statistically analyzed and compared to seven healthy age-matched children. Between both groups, no differences were seen in walking speed, cadence and stride length. The treated patients showed a lower range of motion of the pelvic obliquity and of the trunk obliquity and rotation, but a higher knee flexion. Growth-friendly spinal implants with bilateral rib to pelvis fixation are commonly used in wheelchair children and rarely indicated in ambulatory patients. The presented data show reduced trunk and pelvis motion using this implant construct. These findings help to understand body postural adjustments and add valuable information for families and care providers when considering this surgery. Level of evidence: Therapeutic level IV.

“…Our laboratory is equipped with six high-resolution infrared cameras sampled at the frequency of 100 Hz. Following the plug-in-gait protocol modified by Blondel et al [17][18][19][20], patients were equipped with a set of 36 reflective markers. Six markers were used for the description of the spine (C7, T6, T9, T12, L3, S1).…”
