The outcome following the development of neurological complications after corrective surgery for scoliosis varies from full recovery to a permanent deficit. This study aimed to assess the prognosis and recovery of major neurological deficits in these patients, and to determine the risk factors for non-recovery, at a minimum follow-up of two years. A major neurological deficit was identified in 65 of 8,870 patients who underwent corrective surgery for scoliosis, including eight with complete paraplegia and 57 with incomplete paraplegia. There were 23 male and 42 female patients. Their mean age was 25.0 years (SD 16.3). The aetiology of the scoliosis was idiopathic (n = 6), congenital (n = 23), neuromuscular (n = 11), neurofibromatosis type 1 (n = 6), and others (n = 19). Neurological function was determined by the American Spinal Injury Association (ASIA) impairment scale at a mean follow-up of 45.4 months (SD 17.2). the patients were divided into those with recovery and those with no recovery according to the ASIA scale during follow-up.Aims
Methods
The aim of this study was to investigate the impact of maturity status at the time of surgery on final spinal height in patients with an adolescent idiopathic scoliosis (AIS) using the spine-pelvic index (SPI). The SPI is a self-control ratio that is independent of age and maturity status. The study recruited 152 female patients with a Lenke 1 AIS. The additional inclusion criteria were a thoracic Cobb angle between 45° and 70°, Risser 0 to 1 or 3 to 4 at the time of surgery, and follow-up until 18 years of age or Risser stage 5. The patients were stratified into four groups: Risser 0 to 1 and selective fusion surgery (Group 1), Risser 0 to 1 and non-selective fusion (Group 2), Risser 3 to 4 and selective fusion surgery (Group 3), and Risser 3 to 4 and non-selective fusion (Group 4). The height of spine at follow-up (HOSf) and height of pelvis at follow-up (HOPf) were measured and the predicted HOS (pHOS) was calculated as 2.22 (SPI) × HOPf. One-way analysis of variance (ANOVA) was performed for statistical analysis.Aims
Patients and Methods
There is a paucity of information on the pre-operative coronal
imbalance in patients with degenerative lumbar scoliosis (DLS) and
its influence on surgical outcomes. A total of 284 DLS patients were recruited into this study, among
whom 69 patients were treated surgically and the remaining 215 patients
conservatively Patients were classified based on the coronal balance
distance (CBD): Type A, CBD <
3 cm; Type B, CBD >
3 cm and C7
Plumb Line (C7PL) shifted to the concave side of the curve; Type
C, CBD >
3 cm and C7PL shifted to the convex side.Aims
Patients and Methods
A self-control ratio, the spine-pelvis index
(SPI), was proposed for the assessment of patients with adolescent idiopathic
scoliosis (AIS) in this study. The aim was to evaluate the disproportionate
growth between the spine and pelvis in these patients using SPI.
A total of 64 female patients with thoracic AIS were randomly enrolled
between December 2010 and October 2012 (mean age 13 years, standard
deviation ( No significant difference in SPI was found in different age groups
in the control group, making the SPI an age-independent parameter
with a mean value of 2.219 (2.164 to 2.239). We also found that
the SPI was not related to maturity in the control group. This study, for the first time, used a self-control ratio to
confirm the disproportionate patterns of growth of the spine and
pelvis in patients with thoracic AIS, highlighting that the SPI
is not affected by age or maturity. Cite this article:
