“…One advantage of VBT is the ability to modify growth by using the Hüter-Volkman principle. Another advantage is the chance to preserve spinal flexibility [6,7], which may additionally decrease the incidence for adjacent segment degeneration. However, to be truly motion preserving and to have a clinical relevant effect on adjacent segment degeneration, VBT of the flexible lumbar spine would be of much higher interest than thoracic VBT.…”

Introduction Aim of this study was to analyze the rate of tether breakages after lumbar vertebral body tethering (VBT) and to study the effects and possible benefits of the use of a 2-tether construct. Tether breakage is a known mechanical complication after VBT. However, the literature only refers to thoracic VBT, and no data on the breakage rate or 2-tether construct after lumbar VBT are available. Materials and methods Patients who underwent lumbar VBT with lowest instrumented vertebra at L3 or L4 and had a 1-year follow-up were included. Radiologic data were obtained preoperatively, at the 1st standing X-ray and at the 1-year follow-up to study breakage rate, loss of correction and lumbar lordosis in 1-and 2-tether constructs. Results Data from 30 patients (mean age 14.7 ± 1.8) were available, 12 with double tether. Double tether did not decrease lumbar lordosis. The breakage rate was 24% in segments instrumented with a single tether and 16% in segments instrumented with a double tether (OR 1.6, p = 0.4). Lumbar loss of correction was 10° ± 6.8° in the entire cohort and 12.1° ± 5.4° in patients with a breakage (p = 0.2). Revision rate was 10%, due to tether breakage and loss of correction. Conclusion Breakage rate after lumbar VBT is high, but was improved with the use of a 2-tether construct. Despite tether breakage, loss of correction was limited and the revision rate low. The use of a double tether does not have a kyphotic effect on the lumbar spine.

“…Ein retrospektiver Vergleich thorakolumbaler Skoliosen mit einem mindestens 3-Jahres Follow-up findet sich in einer Studie von Pehlivanoglu et al [32], in der eine Gruppe von AVBT Patienten (n = 21) mit übereinstimmenden Patienten aus einem Kollektiv nach dorsaler Korrekturspondylodese (n = 22) gematcht worden ist. Hier zeigen die Patienten aus der AVBT Gruppe bessere Ergebnisse hinsichtlich der Beweglichkeit sagittal und coronar und bez.…”

ZusammenfassungMit dem Anterior Vertebral Body Tethering (AVBT) steht eine Technik zur Verfügung, welche für die idiopathische Adoleszentenskoliose unter definierten Voraussetzungen eine Wachstumslenkung und damit Korrektur bei weitestgehend Funktionserhalt verspricht. Evidenz liegt im Moment nur für das thorakale AVBT entsprechend den Evidenzgraden III und IV vor. Für lumbale und thorakolumbale Kurven ist auf der Grundlage der zur Verfügung stehenden Literatur in Bezug auf eine mögliche Evidenz keine Aussage möglich. Für einen Einsatz nach Wachstumsabschluss findet sich in der Literatur keine Unterstützung. In Diskussion verbleibt der optimale Operationszeitpunkt in Bezug auf die Skelettreife. Die hohe in der Literatur dokumentierte Zahl an Komplikationen und Nachoperationen erfordert eine weitere Evaluation und Optimierung des Verfahrens.

“…Recently, Pehlivanoglu et al [ 21 ] conducted the first study comparing the functional outcomes of anterior vertebral body tethering (VBT) and posterior spinal fusion (PSF). The VBT group was age-gender-instrumented level and minimum follow-up duration matched with the PSF group, with 21 and 22 patients, respectively.…”

Given the importance of the spine in carrying out daily movements, adolescent idiopathic scoliosis (AIS) can significantly limit the range of motion (ROM). Severe forms of AIS are treated surgically, most commonly with posterior spinal fusion and instrumentation, which may also reduce spine ROM. This review is the first to describe the literature on total spine ROM in patients with AIS before and after corrective surgery. A systematic literature search was performed using PubMed and Google Scholar to identify articles reporting global spine ROM in AIS patients. Following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), 486 articles were initially identified. Two independent reviewers (YM and JH) assessed eligibility for inclusion. A total of 11 articles fit the inclusion criteria. AIS in untreated patients seems to limit axial and coronal plane ROM based on the degree of curve severity, with more severe curves having less ROM. More research comparing total spine ROM in untreated AIS patients to that of healthy controls is needed. In those undergoing spinal fusions, the lowest instrumented vertebra and surgical approach appear to minimize further reductions in ROM; however, the findings are mixed. Vertebral body tethering (VBT) shows promising preliminary results in treating AIS while preserving motion; however, long-term outcomes have yet to be assessed for this novel procedure. The results of this systematic review suggest that further research is required before treatment strategies can be modified for surgically treating patients with AIS to take into account the effects of treatment on changes in spine mobility.
