The aim of this study was to compare outcomes after growth-friendly treatment for early-onset scoliosis (EOS) between patients with skeletal dysplasias versus those with other syndromes. We retrospectively identified 20 patients with skeletal dysplasias and 292 with other syndromes (control group) who had completed surgical growth-friendly EOS treatment between 1 January 2000 and 31 December 2018. We compared radiological parameters, complications, and health-related quality of life (HRQoL) at mean follow-up of 8.6 years (SD 3.3) in the dysplasia group and 6.6 years (SD 2.6) in the control group.Aims
Methods
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
The aim of this study was to compare the treatment ouctomes of severe idiopathic scoliosis (IS) (>90 degrees) using the staged surgery with initial limited internal distraction and typical IS treated using segmental pedicle screw instrumentation. We hypothesized that staged surgical treatment of severe scoliosis would improve more HRQoL and pulmonary function (PF) as compared with posterior spinal fusion (PSF) for typical IS curves. It was a retrospective review of a consecutive series of 60 IS, severe group (SG) vs. moderate group (MG) with min. 2 years of follow up (FU). The mean preoperative major curve (MC) was 120° and thoracic kyphosis (TK) was 80° for the SG and 54° and 17° for the MG, respectively (p<0.001). The MC was corrected to 58° and TK to 32° for the SG; the MC to 26° and TK to 14°, for the MG, respectively (p<0.001). The mean preoperative AVT was 8.9 cm and improved to 2.8 cm at the final FU for the SG and from 6.5 cm to 2.2 cm at the final FU for the MG (p<0.001). At baseline, the FVC% & FEV1% values were significant different between the two groups (41.5% vs. 83%, p <0.001) & (41.6% vs. 77%, p <0.001). Compared the baseline for SG vs. the values at 2-year FU the FVC % values were (41.5% vs. 66.5%, p <0.001), and the baseline for MG vs. the values at 2-year FU, the FEV1 values were (77% vs. 81%, NS). At last FU, no complications were reported. Gradual traction with complicity of multilevel Ponte's osteotomies and neuromonitoring followed by staged pedicle screws instrumentation in severe IS proved to be a safe and effective method improving spinal deformity (52% correction), PF (improved percentage of predicted forced vital capacity by 49%), and health-related quality and allows to achieve progressive curve correction with no neurologic complications associated to more aggressive one-stage surgeries.
It is uncertain whether instrumented spinal fixation in nonambulatory children with neuromuscular scoliosis should finish at L5 or be extended to the pelvis. Pelvic fixation has been shown to be associated with up to 30% complication rates, but is regarded by some as the standard for correction of deformity in these conditions. The incidence of failure when comparing the most caudal level of instrumentation, either L5 or the pelvis, using all-pedicle screw instrumentation has not previously been reported. In this retrospective study, we compared nonambulatory patients undergoing surgery at two centres: one that routinely instrumented to L5 and the other to the pelvis. In all, 91 nonambulatory patients with neuromuscular scoliosis were included. All underwent surgery using bilateral, segmental, pedicle screw instrumentation. A total of 40 patients underwent fusion to L5 and 51 had their fixation extended to the pelvis. The two groups were assessed for differences in terms of clinical and radiological findings, as well as complications.Aims
Methods
In a multicentre, randomised study of adolescents undergoing
posterior spinal fusion for idiopathic scoliosis, we investigated
the effect of adding gelatine matrix with human thrombin to the
standard surgical methods of controlling blood loss. Patients in the intervention group (n = 30) were randomised to
receive a minimum of two and a maximum of four units of gelatine
matrix with thrombin in addition to conventional surgical methods
of achieving haemostasis. Only conventional surgical methods were
used in the control group (n = 30). We measured the intra-operative
and total blood loss (intra-operative blood loss plus post-operative
drain output).Aims
Patients and Methods
We report the results of vertebral column resection
(VCR) for paediatric patients with spinal deformity. A total of
49 VCRs in paediatric patients from four university hospitals between
2005 and 2009 with a minimum two-year follow-up were retrospectively
identified. After excluding single hemivertebral resections (n =
25) and VCRs performed for patients with myelomeningocele (n = 6),
as well as spondylectomies performed for tumour (n = 4), there were
14 patients who had undergone full VCR at a mean age of 12.3 years
(6.5 to 17.9). The aetiology was congenital scoliosis in five, neuromuscular
scoliosis in three, congenital kyphosis in two, global kyphosis
in two, adolescent idiopathic scoliosis in one and secondary scoliosis
in one. A total of seven anteroposterior and seven posterolateral approaches
were used. The mean major curve deformity was 86° (67° to 120°) pre-operatively
and 37° (17° to 80°) at the two-year follow-up; correction was a
mean of 54% (18% to 86%) in the anteroposterior and 60% (41% to
70%) in the posterolateral group at the two-year follow-up (p =
0.53). The mean Scoliosis Research Society-24 total scores were
100 (92 to 108) for the anteroposterior and 102 (95 to 105) for
the posterolateral group. There was one paraparesis in the anteroposterior
group necessitating urgent re-decompression, with a full recovery. Patients undergoing VCR are highly satisfied after a successful
procedure.
To report the results of full vertebral column resection (VCR) for paediatric spinal deformity. All VCR (n=47) for paediatric spinal deformity were retrospectively evaluated from four university hospitals performing these procedures in Finland between 2005 and 2010. After excluding single hemivertebra (n=25) and resections performed for patients with MMC (n=6), 16 patients with full VCR (mean age at surgery 12.9 yrs [6.5-17.9] AIS 1; NMS 3; Congenital scoliosis 3 primary, revision 4; Kyphosis congenital 2, global 2; NF1 scoliosis 1) were identified. Seven procedures were performed anteroposteriorly and nine posterior-only. Mean follow-up time 1.9 (0.6–5.5) years. Major Curve (MC) averaged preoperatively 85 (58–120) degrees, 31 (14-53) degrees at 6 months, and 37 (17-80) degrees at 2-year follow-up. MC correction averaged 61 (46-86)% in the AP and 64 (57-83)% in the PL group at 6 months and 54 (18-86)% and 60 (41-70)% at 2-yr FU, respectively (NS). Blood loss averaged 3400 (500-8200) mL (NS between groups). The mean SRS-24 total scores were 100 (92-108) for AP and 102 (95-105) for PL group. There was one paraparesis in the AP group necessitating urgent re-decompression with full recovery. One peripheral L5 motor deficit resolved fully within few days (PL). Two junctional kyphosis were observed (one in both group). One one-sided partial lower instrumentation pull-out was observed without need for revision. One pseudoarthrosis occurred in AP group needing revision.Purpose
