To provide definitions and a conceptual framework for single position surgery (SPS) applied to circumferential fusion of the lumbar spine. ⋯ Single position surgery in circumferential fusion of the lumbar spine includes posterior fixation in association with any of the following: lateral position LLIF, prone position LLIF, lateral position ALIF, and their combination (lateral position LLIF+ALIF). Preliminary studies have validated these methods.

Many countries ended their professional scoliosis screening due to ongoing controversies. Discontinuation resulted in a shift of screening responsibility from trained healthcare professionals to untrained parents. ⋯ The sensitivity of screening for scoliosis was significantly lower when it was performed by parents, while the false-positive rate was similar to healthcare professionals. The window of opportunity for conservative treatment may be missed when parents rather than professionals are responsible for screening.

The Osteoporotic Fracture Working Group (Spine Division of the German Orthopaedic and Trauma Society) has developed a classification system for osteoporotic thoracolumbar fractures, namely the osteoporotic fracture (OF) classification system. The purpose of this study was to determine the inter- and intraobserver reliabilities of the OF classification system for osteoporotic vertebral body fractures (VFs) at a level-one trauma centre. ⋯ The OF classification system is easy to use. It shows good interobserver reliability and substantial intraobserver reliability if diagnostic prerequisites (conventional radiography, MRI, and CT scans) are met.

Prone transpsoas fusion (PTP) is a minimally invasive technique that maximizes the benefit of lateral access interbody surgery and the prone positioning for surgically significant adjacent segment disease. The authors describe the feasibility, reproducibility and radiographic efficacy of PTP when performed for cases of lumbar ASD. ⋯ Single-position prone transpsoas lumbar interbody fusion is a clinically reproducible minimally invasive technique that can effectively treat lumbar adjacent segment disease.

Tether breakage is a frequent mechanical complications after vertebral body tethering (VBT), but not all patients with a breakage show loss of correction. The reason of this clinical finding has not yet been clarified. We hypothesized that the integrity of the tether is relevant only in the early stages after VBT, when it drives growth modulation and tissue remodelling. After these mechanisms have taken place, the tether loses its function and a breakage will not alter the new shape of the spine. Thus, tether breakage would have a greater clinical relevance when occurring shortly after surgery. ⋯ Tether breakage leads to a consistent loss of correction when occurring within the first 12 months, while it has limited clinical relevance when occurring later on.
