Surgical treatment of spinal deformity is high risk in patients suffering from Parkinson’s disease (PD). Several series have already reported a high rate of complications. However, none of these studies included more than 40 patients and none of the risk factors of complications were described. The aim of this study was to describe the rate and risk factors of revision surgery as well as the clinical outcome at the last visit in a large multicenter study of PD patients operated for spinal deformities.


A multicenter retrospective study included arthrodesis for spinal deformity in patients with PD. Clinical and surgical data including revision surgeries were collected. Assessment of functional outcomes at last follow-up was classified in 3 grades and spinal balance was assessed on anteroposterior and lateral plain X-rays of the entire spine.


Forty-eight patients were included. Median age was 67 years old (range 41-80). Median follow-up was 27 months. The rate of surgical revision was 42%. Eighty per cent of revisions were performed for chronic mechanical complication. Global results were considered to be good in 17 patients (35%), doubtful in 17 patients (35%) and a failure in 14 patients (30%), for the whole series.


The results of surgery for spinal deformities in patients with Parkinson disease vary with a high rate of complications and revisions. Nevertheless, these results should be seen in relation to the natural progression of these spinal deformities once spinal imbalance has developed. The association between preoperative clinical balance and final outcome suggests that early surgery can probably play a role in treatment.

Postural deformities in the coronal plane were frequent and disabling complications of PD, which reduces the quality of life of patients. This study aimed to garner greater attention to the Parkinson disease (PD)-related postural trunk deviations in the coronal plane by exploring a method for diagnosis because of the lack of any uniform diagnostic criteria and epidemiological studies. It also aimed to provide correlation data in the Chinese PD patients.


In this cross-sectional study, 503 consecutive outpatients with PD were enrolled who underwent standardized clinical evaluation. The study recruited 83 PD patients diagnosed with Pisa syndrome (PS). Scoliosis and coronal imbalance were diagnosed accurately by radiographic data. The PD patients were compared based on the Cobb angle and coronal balance for several demographic and clinical variables.


PD patients with PS had a prevalence of 16.5%. The prevalence of coronal imbalance and scoliosis was 10.34 and 7.75%, respectively. PD patients with PS were older and had a more severe disease, significantly longer disease duration and treatment duration, and reduced quality of life. The most important finding was that the different morphology of the spinal level had an effect on the severity of coronal balance or Cobb angle.


The present study indicated that the postural deformities in the coronal plane were related to the morphology of the spinal level, especially the position of the Cobb angle. To benefit the PD patients with PS, the full-length standing spine radiographs should be performed as early as possible.

Randomized controlled trial.


This study investigated on the effectiveness of chewing gum on promoting faster bowel function and its ability to hasten recovery for adolescent idiopathic scoliosis (AIS) patients following posterior spinal fusion (PSF) surgery.


Sham feeding with chewing gum had been reported to reducethe incidence of post-operative ileus by accelerating recovery of bowel function.


We prospectively recruited and randomized 60 AIS patients scheduled for PSF surgery into treatment (chewing gum) and control group.The patient controlled anesthesia usage, wound pain score, abdominal pain score, nausea score and abdominal girth were assessed and recorded at 12, 24, 36, 48 and 60 hours post-operatively. The timing for the first fluid intake, first oral intake, sitting up, walking, first flatus after surgery, first bowel opening after surgery and duration of hospital stay were also assessed and recorded.


We found that there were no significant differences (p > 0.05) patient controlled anesthesia usage, wound pain score, abdominal pain score, nausea score and abdominal girth between treatment (chewing gum) and control groups. We also found that therewere no significant difference (p > 0.05) in post-operative recovery parameters which were the first fluid intake, first oral intake, sitting up after surgery, walking after surgery, first flatus after surgery, first bowel opening after surgery and duration of hospital stay between both groups. The wound pain was the worst at 12 hours post-operatively which progressively improved in both groups. The abdominal pain progressively worsened to the highest score at 48 hours in the treatment group and 36 hours in the control group before improving after that. The pattern of severity and recovery of wound pain and abdominal pain were different.


We found that chewing gum did not significantly reduce the abdominal pain, promote faster bowel function or hasten patient recovery.

Prospective cross-sectional study OBJECTIVE.: To evaluate patients’ and parents’ concerns so they can be addressed with appropriate preoperative counseling.


Despite much research on outcomes for posterior spinal fusion (PSF) in adolescent idiopathic scoliosis (AIS), little is available about preoperative fears or concerns.


AIS patients undergoing PSF, their parents, and surgeons, were prospectively enrolled and asked to complete a survey on their fears and concerns about surgery at their preoperative appointment.


Forty-eight patients and parents completed surveys. Four attending pediatric spine surgeons participated and submitted 48 responses. Mean age of patients was 14.2 years. On a scale of 0-10, mean level of concern reported by parents (6.9) was higher than that reported by patients (4.6). Surgeons rated the procedure’s complexity on a scale of 0-10 and reported a mean of 5.2. Neither patients’ nor parents’ level of concern correlated with the surgeons’ assessment of the procedure’s complexity level (R = 0.19 and 0.12, p = 0.20 and p = 0.42 respectively). Top 3 concerns for patients were pain (25%), ability to return to activities (21%), and neurologic injury (17%). Top 3 concerns for parents were pain (35%), neurologic injury (21%), and amount of correction (17%). Top 3 concerns for surgeons were postoperative shoulder balance (44%), neurologic injury (27%), and LIV selection (27%). Patients reported the same concerns 23% of the time as parents, and 17% of the time as surgeons. Parents and surgeons reported the same concerns 21% of the time.


Pain was the greatest concern for both patients and parents but was rarely listed as a concern by surgeons. Parent and patient level of concern did not correlate to the surgeon’s assessment of the procedure’s complexity. Neurologic injury was a top concern for all groups, but otherwise there was little overlap between physician, patient and parent concerns.

CHICAGO — A speaker here at the American Academy of Orthotists and Prosthetists Annual Meeting and Scientific Symposium developed a survey to poll spinal orthotists and to identify areas of agreement or disagreement regarding orthotic biomechanical correction theory of adolescent idiopathic scoliosis.

Sun Hae Jang, MSc, CO, FAAOP, a PhD candidate at Eastern Michigan University, and colleagues polled 46 certified orthotists and certified prosthetist-orthotists with at least 2 years of experience in scoliosis-orthotic treatment. Overall, 21 multiple-choice questions were developed that focused on general concepts and case examples in the orthotic-biomechanical field. Researchers calculated the number of participants who picked each multiple-choice option and identified the ratio of agreement vs. disagreement.

Researchers found agreement on 11 biomechanical-orthotic correction topics. There were seven topics on which participants did not find clear agreement, and the most disagreement occurred on questions regarding the sagittal plane.

Using the collected data, researchers conducted a review of literature on each area of disagreement. Jang said most studies supported that the superior edge of a thoracic pad should be placed on the rib attached at the apex of the thoracic curve or on the levels caudal to the apex.

“We found that abdominal compression has the function of superimposing a longitudinal stretch on the lumbar and thoracic spines by increasing intra-abdominal pressure,” Jang said. “Abdominal pressure is also related to reducing lumbar lordosis. However, most articles proposed that if someone has a thoracic scoliosis curve, unnecessary reduction of lumbar lordosis, including abdominal compression, could be contraindicated.”

Jang said evidence shows that cervical-thoracic-lumbar-sacral orthoses are the best option for T2-T6 curvatures. “However, patient compliance issues have been noted,” she said. “A shoulder ring is recommended to control cervico-thoracic scoliotic curves, and a trapezius pad is recommended to control high thoracic curves.”

According to Jang, more quantitative research is needed to understand biomechanical correction concepts and orthotists should treat patients based on generally defined concepts – by Shawn M. Carter
