Rate of Scoliosis Correction After Anterior Spinal Growth Tethering for Idiopathic Scoliosis

Abstract

Background:The purpose of the present study was to evaluate associations between changes in segmental vertebral coronal angulation (screw angulation) and overall height after anterior spinal growth tethering for the treatment of idiopathic scoliosis and to compare the rates of coronal angulation change using the preoperative Sanders stage.Methods: Patients with idiopathic scoliosis who underwent anterior spinal growth tethering between 2012 and 2016 and had ‡2 years of follow-up were retrospectively studied. We calculated each segment's screw angulation rate of change (degrees/month) and each patient's height velocity (cm/month) between each of the visits (3 to 12 visits/patient) and divided the visits into 4 groups by postoperative duration (<1 year, 1 to 2 years, >2 to 3 years, >3 years). Patients were divided into 2 groups according to the preoperative Sanders stage. Generalized estimating equations and repeatedmeasures correlation were utilized for analyses with non-independent samples.

“…The pooled overall unplanned reoperation rate was calculated to investigate further surgical treatment due to UPROR after VBT treatment. Twenty-three included studies involved 948 patients 13,14,22,[25][26][27][28][29][30][31][32][34][35][36][37][38][39][40][41][42][43][44][45] and 93 patients underwent unplanned reoperation after VBT surgery (I 2 = 43%, p < .1). There was some heterogeneity among the studies.…”

“…The pooled overall incidence rate of complications was analyzed to investigate the safety and complications of VBT for treating scoliosis. A total of 24 studies reported complications 13,14,22,[24][25][26][27][28][29][30][31][32][34][35][36][37][38][39][40][41][42][43][44][45] and involved 1004 patients. Two hundred and eight-six patients had adverse reactions after VBT.…”

Bewegungserhaltende operative Korrektur der idiopathischen Adoleszentenskoliose – Evidenz

“…Die meisten präsentierten Verläufe haben ein Follow-up von 2 bis 4 Jahren mit endgültigen Korrekturen zwischen ca. 45°bis 65°bezogen auf die Ausgangskrümmung [15,[21][22][23][24][25]. Daten mit einem Follow-up größer 4 Jahre unterstützen die Aussagen bezüglich der so zu erzielenden Korrekturen [16,26].…”
