Sagittal spino-pelvic parameters of adult isthmic spondylolisthesis

چکیده
Methods 60 patients with L5-S1 isthmic spondylolisthesis (mean age, 47years, range, 28 to 69 years) and age-matched control group of 77 normal adults (mean age, 43.5 years, range, 25 to 63 years) were recruted in this retrospective study. Parameters including slip distance (SD), slipping percentage (SP), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), L5 incidence (L5I), lumbar-sacral angle (LSA), lumbar lordosis (LL), sagittal vertical axis (SVA) were measured on the long-cassette standing upright lateral radiographs of the spine and pelvis. Patients with spondylolisthesis were divided into two groups based on slipping percentage : Low grade : group A with SP<30percent (30 cases of 60) and high grade: group B with SP >30percent (30 cases of 60). Differences in sagittal parameters among groups were analyzed using independent samples t-test, and Pearsons correlation coefficients were used to investigate the relationship between spino-pelvic parameters and SP.

Current concepts on the sagittal balance and classification of spondylolysis and spondylolisthesis☆☆☆
Treatment of spondylolysis and spondylolisthesis remains a challenge for orthopaedic surgeons, neurosurgeons and paediatrics. In spondylolisthesis, it has been clearly demonstrated over the past decade that spino-pelvic morphology is abnormal and that it can be associated to an abnormal sacro-pelvic orientation as well as to a disturbed global sagittal balance of spine. This article presents th...

OBJECTIVE The purpose of this study was to analyze the differences of spinopelvic parameters between degenerative spondylolisthesis (DSPL) and isthmic spondylolisthesis (ISPL) patients. METHODS Thirty-four patients with DSPL and 19 patients with ISPL were included in this study. Spinopelvic parameters were evaluated on whole spine X-rays in a standing position. The following spinopelvic param...

BACKGROUND Pelvic incidence, sacral slope and slip percentage have been shown to be important predicting factors for assessing the risk of progression of low- and high-grade spondylolisthesis. Biomechanical factors, which affect the stress distribution and the mechanisms involved in the vertebral slippage, may also influence the risk of progression, but they are still not well known. The object...
