This article aims to provide an overview of how spinal deformities can alter normal spine and thoracic cage growth. ⋯ Growth is a succession of acceleration and deceleration phases and a perfect knowledge of normal growth parameters is mandatory to understand the pathologic modifications induced on a growing spine by an early onset spinal deformity. The challenges associated with the growing spine for the surgeon include preservation of the thoracic spine, thoracic cage, and lung growth without reducing spinal motion.

Randomized Controlled Trial
An anatomic study of the interspinous space of the lumbosacral spine.
The purpose of this study is to quantify the interspinous anatomy at the L4/5 and L5/S1 levels. ⋯ The interspinous space available, as defined by computer tomography, at the L5/S1 level, is less able to accommodate current interspinous devices compared to the adjacent L4/5 level. The limiting factor is the length of the sacral part of the L5-S1 interspinous space.

Randomized Controlled Trial
Use of computed tomographic reconstruction to establish the ideal entry point for pedicle screws in idiopathic scoliosis.
To determine the ideal entry point for individual pedicle screw in the surgical treatment of idiopathic scoliosis using computed tomographic (CT) three-dimensional (3D) reconstruction. ⋯ We conclude that in the surgical treatment of severe scoliosis, individual screw placement guided by entry points determined by CT reconstruction can result in improved accuracy and ease of the procedure.

Comparative Study Clinical Trial
Responsiveness of the Oswestry Disability Index and the Roland Morris Disability Questionnaire in Italian subjects with sub-acute and chronic low back pain.
An ability to assess longitudinal changes in health status is crucial for the outcome measures used in treatment efficacy trials. The aim of this study was to verify the responsiveness of the Italian versions of the Oswestry Disability Index (ODI) and the Roland Morris Disability Questionnaire (RMDQ) in subjects with subacute or chronic low back pain (LBP). ⋯ The Italian ODI and RMDQ proved to be sensitive in detecting clinical changes after conservative treatment for subacute and chronic LBP. Our findings are consistent with those published in the literature, thus allowing cross-cultural comparisons and stimulating cross-national studies.

Comparative Study
Predicting the peak growth velocity in the individual child: validation of a new growth model.
Predicting the peak growth velocity in an individual patient with adolescent idiopathic scoliosis is essential or determining the prognosis of the disorder and timing of the (surgical) treatment. Until the present time, no accurate method has been found to predict the timing and magnitude of the pubertal growth spurt in the individual child. A mathematical model was developed in which the partial individual growth velocity curve was linked to the generic growth velocity curve. ⋯ Using only 0.5 years of data as input, the predictions with a starting age from 13 to 15.5 years in boys and from 9.5 to 14.5 years in girls were significantly better. Similar results were found for the predictions of the magnitude of the PGV. This model showed highly accurate results in predicting the individual age and magnitude of the PGV, which can be used in the treatment of patients with adolescent idiopathic scoliosis.
