Introduction:Sagittal imbalance leads to muscular distress and results in low back pain.Objectives: This study scrutinize the segmental impact of short spinal fusion on spinopelvic parameters and the global patient’s clinical outcome. Materials and Methods: A retrospective analysis evaluated 56-patients who underwent lumbar fusion surgery at Klinikum Dortmund, from July 2013 to February 2014. The population was allocated into two groups: (1-level group), (2-levels group). EOS imaging applied for radiological evaluation and measurements of the following spinopelvic parameters: pelvic incidence (PI), sacral slope (SS), pelvic tilt (SS), lumbar lordosis (LL), and sagittal vertical axis (SVA). The radiological measurements were implemented during the preoperative, postoperative, 3 months and 1 year follow-up visits. All patients completed clinical questionnaires.Results: Statistically, the Pearson correlation coefficient revealed in the 1-level group that the clinical parameters correlated with the PT (R=0.40), SSA (R=-0.38) and SVA (R=-0.41) (p<0.05). While clinically, the mean preoperative VAS and mean ODI improved significantly in both groups.There was also a high correspondence between LL and SS (R=0.90); this relationship persisted at the same level even after a year. For the 2-level group, the only parameter that was interrelated with clinical parameters was the SVA (R=0.49) (p<0.05). There was also a high correlation between LL and SS (R=0.88).Conclusion: Scrutiny conducted showed: Patient with one level would improve clinically in terms of pain and radiculopathy, with only small alterations in spino-pelvic parameters. Meanwhile, two-level fusions have a statistically substantial clinical improvement interrelated to re-establishment of lumbar lordosis and sagittal vertical axis.

Introduction: Hydrocephalus (HCP) remains one of the commonest pathologies treated in developing countries. Endoscopic third ventriculostomy (ETV) has become the alternative to shunt-divergen procedures in the treatment of many pathologies of the cerebral fluid in the brain. Age has been considered a limitation to perform the procedure, we started to perform ETV In younger patients earlier than many other units. Objectives: In this study, we demonstrate the overall efficacy of ETV in infants younger than 1-year of age and to subsequently report the outcome of this procedure. Methods: From 2000 till 2016 we have performed a total of 386 cases of ETV of all ages. 71-cases were infants (below 1-year of age). Our study was undertaken to evaluate these cases. Patients were divided into two subgroups according to the cause of hydrocephalus; obstructive HCP, communicating HCP. Results: Mean time for follow up was 52 months. Mean age at surgery was 137days (7- 351days). The population included 31-females and 40-males, while10 infants were premature. Success rates were; 91.6%, 63.6% correspond to each sub-group with an overall success rate of 73.24%. Conclusion: ETV in infants is feasible, technically more demanding. Success rate justifies the procedure to be performed in such age group of patients. ETV can be used, attentively, in cases of hydrocephalus associated with MMC, morbidity and mortality does not differ from the general population.
