The fusion in situ group seems to perform better in almost all clinical parameters measured. These findings suggest that fusion in situ should be considered as a method of choice in severe L5 isthmic spondylolisthesis.
In patients with adolescent idiopathic scoliosis who undergo surgery with Harrington instrumentation, the overall long-term clinical outcome does not correlate with the radiologic outcome. However, a significant inverse correlation was found between the magnitude of the primary thoracic curve at follow-up assessment and the scores for questions on cosmetic matters in the Scoliosis Research Society questionnaire. Spine mobility is diminished as a result of spondylodesis, but the patients perform, on the average, as well as the normal population in nondynamometric trunk strength measurements.
The aim of the study was to assess the results of treatment of adolescent idiopathic scoliosis (AIS) with the Providence nighttime brace at 1.8 years after discontinuation of bracing. A total of 36 consecutive female patients with an average Cobb angle of 28.4 degrees and an apex below T 10 were studied prospectively. For comparisons, 36 matched patients treated with the Boston full-time brace were studied retrospectively. With the Providence night brace an average of 92% for brace correction of the primary curve was achieved and during follow-up progression of the curve >5 degrees occurred in 27% of the patients. In the control group of the Boston full-time brace patients, brace correction was 50% and the progression of the major curve occurred in 22% of the patients. We conclude that the Providence night brace may be recommended for the treatment of AIS with curves less than 35 degrees in lumbar and thoracolumbar cases.
The aim of the study was to compare the results of brace treatment of adolescent idiopathic scoliosis (AIS) in male patients with matched female patients and to assess the effectiveness of bracing of boys in AIS and to discuss the results with published data. Between 1987 and 1995, 51 consecutive male patients with AIS were treated with the Boston brace. The patients were advised to wear the brace 23 h/day. The medical records of all patients were reviewed. Cobb angles and Risser signs were measured before bracing, in brace, at brace discontinuation and at final follow-up. Everyone of 51 male patients was compared with a female patient who was treated by the same method and matched by Risser sign, curve pattern, curve magnitude and duration of treatment and follow-up time. Compliance with brace was noted at every visit. Fourteen boys had worn the brace only during nighttime or occasionally and were considered non-compliant. Only compliant patients with treatment period > 1 year and follow-up > 1 year after treatment were accepted for the analyses of effectiveness of brace treatment and its prognostic factors. Thirty-three boys met these inclusion criteria. Bracing was considered to have a failure if > 5 degrees progression occurred or if surgery was performed. At the final follow-up study progression > 5 degrees was found in 16/51 (31.4%) of male patients. Corresponding figures of female patients were 11/51 (21.6%), respectively. In compliant boys progression > 5 degrees occurred in 6/33 boys compared with 9/33 girls. The association between risk of progression and correction% in brace was statistically significant. The overall results of brace treatment of idiopathic scoliosis in male patients were inferior compared with matched females. One reason for inferior overall results in boys was poor compliance with brace wear. However, brace treatment in AIS may be recommended with the same principles in both genders.
The midterm radiologic and functional outcomes were quite similar in both groups as were the SRS scores. The patients performed, on average, as well as did the reference population in nondynamometric trunk strength measurements. Intraoperative and late complications were similar in both groups.
The clinical outcome was best in the CF group as measured by ODI. Degenerative changes were most commonly found at the level of the slip and above the fusion level. The prevalence of disc prolapses was low. Spinal fusion for isthmic spondylolysis is not associated with central canal stenosis above the fusion. Radiologic nerve root stenosis was common but asymptomatic. Mild muscle atrophy was common.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
