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 compared the clinical, radiological and quality-of-life
outcomes between hybrid and total pedicle screw instrumentation
in patients undergoing surgery for neuromuscular scoliosis. Total pedicle screw instrumentation provided shorter operating
times, less blood loss and better correction of the major curve
compared with hybrid constructs in patients undergoing surgery for
neuromuscular scoliosis.
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
