The aim of this study was to evaluate whether, after correction of an adolescent idiopathic scoliosis (AIS), leaving out the subfascial drain gives results that are no worse than using a drain in terms of total blood loss, drop in haemoglobin level, and opioid consumption. Adolescents (aged between 10 and 21 years) with an idiopathic scoliosis (major curve ≥ 45°) were eligible for inclusion in this randomized controlled noninferiority trial (n = 125). A total of 90 adolescents who had undergone segmental pedicle screw instrumentation were randomized into no-drain or drain groups at the time of wound closure using the sealed envelope technique (1:1). The primary outcome was a drop in the haemoglobin level during first three postoperative days. Secondary outcomes were 48-hour postoperative oxycodone consumption and surgical complications.Aims
Methods
There is little information about the optimum number of implants
to be used in the surgical treatment of idiopathic scoliosis. Retrospective
analysis of prospectively collected data from the Swedish spine
register was undertaken to discover whether more implants per operated
vertebra (implant density) leads to a better outcome in the treatment of
idiopathic scoliosis. The hypothesis was that implant density is
not associated with patient-reported outcomes, the correction of
the curve or the rate of reoperation. A total of 328 patients with idiopathic scoliosis, aged between
ten and 20 years at the time of surgery, were identified in the
Swedish spine register (Swespine) and had patient reported outcomes
including the Scoliosis Research Society 22r instrument (SRS-22r)
score, EuroQol 5 dimensions quality of life, 3 level (EQ-5D-3L)
score and a Viual Analogue Score (VAS) for back pain, at a mean
follow-up of 3.1 years and reoperation data at a mean follow-up
of 5.5 years. Implant data and the correction of the curve were
assessed from radiographs, preoperatively and a mean of 1.9 years
postoperatively. The patients were divided into tertiles based on
implant density. Data were analyzed with analysis of variance, logistic
regression or log-rank test. Some analyses were adjusted for gender,
age at the time of surgery, the flexibility of the major curve and
follow-up.Aims
