Although distraction-based growing rods (GR) are the gold standard for the treatment of early onset scoliosis, they suffer from high failure rates. We have (1) performed a literature search to understand the deficiencies of the current protocols, (2) in vitro evaluation of GRs using our proposed protocol and performed a finite element (FE) model validation, and (3) identified key features which should be considered in mechanical testing setups. ⋯ The two-way approach presented in this study can lead to a robust prediction of the contributing factors to the in vivo failure.

The importance of sagittal alignment restoration in early onset scoliosis (EOS) management has rarely been investigated to date. The aim was to report the influence of magnetically controlled growing rods (MCGR) insertion on the sagittal alignment of EOS patients. ⋯ IV.

Periprosthetic bone loss is a common observation following arthroplasty. Recognizing and understanding the nature of bone loss is vital as it determines the subsequent performance of the device and the overall outcome. Despite its significance, the term "bone loss" is often misused to describe inflammatory osteolysis, a complication with vastly different clinical outcomes and treatment plans. Therefore, the goal of this review was to report major findings related to vertebral radiographic bone changes around cervical disc replacements, mitigate discrepancies in clinical reports by introducing uniform terminology to the field, and establish a precedence that can be used to identify the important nuances between these distinct complications. ⋯ Diagnostic: individual cross-sectional studies with consistently applied reference standard and blinding.

A pain intensity of 3 can reliably distinguish idiopathic scoliosis (IS) patients with acceptable pain or not. This research aims to analyze psychosocial, family and quality of life differences in patients according to their pain status. ⋯ Patients with IS and unacceptable pain constitute a group with a different incidence of psychological, social, family and comorbidities factors than those with acceptable pain. In contrast, the severity of IS was not substantially different between the groups. This profile is similar to that observed in patients with nonspecific spinal pain.
