Summary of Background
Data. Children born with myelomeningocele have often complex spino-pelvic deformities leading to skin ulcerations. Methods. A cohort of 19 consecutive wheelchair dependent patients with myelodisplastic spinal deformities, who underwent spinal surgery, was prospectively followed with regular pressure mappings for a minimum of 2 years. Standard spino-pelvic radiologic measurements were obtained. Sitting pressure mappings were obtained over the study period using the Force Sensitive Applications from Vista Medical (Winnipeg, Manitoba, Canada). Statistical analysis was done using SAS (SAS Institute Inc, Cary, NC). Paired t-test and Wilcox on Signed Rank test selleck products was used where applicable. Significance was taken to be BGJ398 mw P < 0.05.
Results. Surgery significantly corrected radiographic parameters, specifically, Cobb angle (52%), pelvic obliquity (89%), and to a lesser degree
pelvic tilt. Stratifying the data based on fixation type showed that the M-W construct was able to significantly correct pelvic obliquity. While significant changes in radiographic variables were observed after surgery, this was not the case with the various pressure mapping variables. Only minor changes after surgery were observed in the average pressure, maximum pressure, and variable coefficient of pressure. What was observed was an improvement in the overall distribution from anterior/posterior and right/left. While the values only approached statistical significance (P = 0.053) for right/left, however, this did not appear to be clinically significant regarding skin ulceration.
Conclusion. Despite significant surgical corrections in radiographic parameters, these resulted in small changes in pressure distributions and do AS1842856 cost not appear to influence skin ulceration in the myelomeningocele patient. Pressure mapping may not be a useful tool in predicting outcome of spinal
surgery. Factors which were proven to influence pressure distribution are the sagittal pelvic orientation and also achieving coronal spine balance.”
“Study Design. Systematic review.
Objective. To investigate the prognostic value of clinically induced changes in spinal symptoms (i.e., symptom response) in the conservative management of spinal pain.
Summary of Background Data. Symptom response is used by clinicians to inform management decisions. Understanding the prognostic value of symptom response can aid in this decision-making process. Methods. A search of Ovid-Medline, Ovid-Embase, Ovid-Cinahl, Ovid-Amed, reference lists and citation tracking was performed. Methodologic quality was assessed independently by 2 raters.
Results. We included 22 articles reporting 18 different cohorts. The evidence was limited and mainly involved low back pain. We found no association between most symptom responses and clinical outcomes.
