Late presentation of superior mesenteric artery syndrome following scoliosis surgery: a case report
<p>Abstract</p> <p>Introduction</p> <p>Obstruction of the third part of the duodenum by the superior mesenteric artery (SMA) can occur following surgical correction of scoliosis. The condition most commonly occurs in significantly underweight patients with severe deformities during the first few days to a week following spinal surgery.</p> <p>Case presentation</p> <p>We present the atypical case of a patient with normal body habitus and a 50° adolescent idiopathic thoracolumbar scoliosis who underwent anterior spinal arthrodesis with instrumentation and developed SMA syndrome due to progressive weight loss several weeks postoperatively. The condition manifested with recurrent vomiting, abdominal distension, marked dehydration, and severe electrolyte disorder. Prolonged nasogastric decompression and nasojejunal feeding resulted in resolution of the symptoms with no recurrence at follow-up. The spinal instrumentation was retained and a solid spinal fusion was achieved with good spinal balance in both the coronal and sagittal planes.</p> <p>Conclusion</p> <p>SMA syndrome can occur much later than previously reported and with potentially life-threatening symptoms following scoliosis correction. Early recognition of the condition and institution of appropriate conservative measures is critical to prevent the development of severe complications including the risk of death.</p
Staged surgical treatment for severe and rigid scoliosis
<p>Abstract</p> <p>Background</p> <p>A retrospective study of staged surgery for severe rigid scoliosis. The purpose of this study was to evaluate the result of staged surgery in treatment of severe rigid scoliosis and to discuss the indications.</p> <p>Methods</p> <p>From 1998 to 2006, 21 cases of severe rigid scoliosis with coronal Cobb angle more than 80° were treated by staged surgeries including anterior release and halo-pelvic traction as first stage surgery and posterior instrumentation and spinal fusion as second stage. Pedicle subtraction osteotomy(PSO) was added in second stage according to spine rigidity. Among the 21 patients, 8 were male and 13 female with an average age of 15.3 years (rang from 4 to 23 years). The mean pre-operative Cobb angle was 110.5° (80°-145°) with a mean spine flexibility of 13%. Radiological parameters at different operative time points were analyzed (mean time of follow-up: 51 months).</p> <p>Results</p> <p>External appearance of all patients improved significantly. The average correction rate was 65.2% (ranging from 39.8% to 79.5%) with mean correction loss of 2.23° at the end of follow-up. No decompensation of trunk has been found. Mean distance between the midline of C7 and midsacral line was 1.19 cm ± 0.51. Two patients had neurological complications: one patient had motor deficit and recovered incompletely.</p> <p>Conclusion</p> <p>Staged operation and halo-pelvic traction offer a safe and effective way in treatment of severe rigid scoliosis. Patients whose Cobb angle was more than 80° and the flexibility of the spine was less than 20% should be treated in this way, and those whose flexibility of the spine was less than 10% and the Cobb angle remained more than 70° after 1st stage anterior release and halo-pelvic traction should undergo pedicle subtraction osteotomy (PSO) in the second surgery.</p
The use of dynamic elastomeric fabric orthosis suits as an orthotic intervention in the management of children with neuropathic onset scoliosis: A retrospective audit of routine clinical case notes
BACKGROUND: To date the main treatment approach for neuropathic onset scoliosis has utilised thoracic lumbar sacral orthoses (TLSO) to stabilize the spine and enable stable sitting. Dynamic elastomeric fabric orthoses (DEFOs) may achieve both of these aims if used as an early intervention. Due to a lack of evidence in this area, a retrospective audit of case notes was undertaken to understand current orthotic practice investigating the usage, outcomes and clinical characteristics of treated children with neuropathic onset scoliosis. Clinical notes of 180 children at risk for, or identified with, scoliosis were audited using a search matrix to identify diagnostic group, spinal muscle tone, Gross Motor Functional Classification Scale (GMFCS) level, orthotic treatment modalities, scoliosis specific data, surgical interventions, adaptive technologies used, and outcome measurements reported. RESULTS: Of the 180 notes examined, 85 were male; mean age nine years one month [SD four years seven months]. Spinal muscle tone was reported in 137 cases: 122/137 presented as low tone, 4/137 high tone, 6/137 fluctuating tone and 5/137 typical tone. Scoliosis was confirmed in (77/180) of whom (39/77) used a DEFO. Another (43/180) had a spinal curve developing, of whom (22/43) used a DEFO. The remaining (60/180) had no report of spinal curvature, but used a DEFO as a preventative measure. GMFCS scores were reported for 49 children of whom 14/49 were graded as level 4 and 17/49 level 5. Of the children with scoliosis who had spinal curve shapes reported, 48/60 had a C-shape presentation and 12/60 had an S-shape. CONCLUSIONS: The findings confirm previously reported papers in children with neuropathic onset scoliosis in relation to curve shape and GMFCS levels. It provides some evidence of the role DEFOs may have in the management of these children, and highlights the need for further research in this area due to the lack of peer-reviewed publications
Comparison of parents' and caregivers' satisfaction after spinal fusion in children with cerebral palsy
The purpose of this study was to delineate parents’ and professional
caretakers’ satisfaction after spinal fusion in children with spasticity
and to determine differences in their perceptions. A questionnaire
assessing patients’ functional improvement after spinal arthrodesis for
correcting scoliosis was addressed to 190 parents. An expanded
questionnaire was also addressed to 122 educators and therapists working
in the care of children with cerebral palsy. Caretakers did not
recognize effects of the scoliotic deformity on patients’ head control,
hand use, and feeding ability. Most of parents and caregivers reported a
very positive impact of the surgery on patients’ overall function,
quality of life, and ease of care. Parents had more appreciation of the
benefits in the children’s appearance, whereas educators and therapists
acknowledged more improvement in gross and oral motor function.
Considering that the benefits from scoliosis correction clearly outweigh
the increased risk of surgical complications, most parents (95.8%) and
caretakers (84.3%) would recommend spine surgery
Impact of changing foot progression angle on foot pressure measurement in children with neuromuscular diseases
To analyze the effect of lower-limb rotation on foot pressure
distribution, 16 patients (23 feet) with neuromuscular diseases who
received derotation osteotomy of lower limbs without concomitant
foot-ankle procedures were included in this retrospective study. The
cross-correlation analysis showed that the interval change of the foot
progression angle was correlated with the interval change of the
medial-lateral foot pressure impulse distribution. The externally
rotated foot progression angle tends to introduce higher loading on the
medial foot, and the internally rotated foot progression angle shifts
the loading to lateral side of the foot. This study provides evidence
that the rotational profile of the lower limb has a substantial impact
on foot pressure distribution. (C) 2003 Elsevier B.V. All rights

Distal hamstring lengthening in ambulatory children with cerebral palsy: primary versus revision procedures
To document the benefits and limitations of distal hamstring lengthening
(HL), 61 children (105 limbs) with cerebral palsy treated by distal HL
with complete preoperative and postoperative evaluations were reviewed.
There was significant improvement in popliteal angle, fixed knee flexion
contracture, knee angle at foot contact (FC), and mid-stance knee
extension after HL. On the other hand, the hip power generation peak
decreased, and the anterior pelvic tilt increased. For the repeated HL
(22 limbs), the fixed knee flexion contracture and knee flexion at FC
improved. In a group of ten patients (17 limbs) with further
postoperative follow up evaluations, the only significant clinical
finding related to hamstring function between the first postoperative
and the follow up evaluations with no intervening surgery was an
increase in the popliteal angle of 20degrees. Because the popliteal
angle may increase over time after HL with no other directly related
gait changes, the indications for repeated HL should include fixed knee
flexion contracture and increased knee flexion at FC. The increase in
the popliteal angle alone should not be considered an indication for
repeated HL. (C) 2003 Elsevier B.V. All rights reserved
