Background & Aim: The purpose of this study was to evaluate and compare the pain of patients with spondylolisthesis who had undergone either of the surgery techniques: posterolateral fusion (PLF) or posterior lumbar interbody fusion (PLIF).Methods & Materials\Patients: In a prospective observational study, 102 surgical candidates with low grade degenerative and isthmic spondylolisthesis were enrolled from 2012 to 2014. The observed patients were into two groups: PLF and PLIF. Assessing of pain has been done by a questionnaire using Visual Analogue Scale (VAS) scores. The questionnaire was completed by all patients before surgery, the day after surgery, after six months and after one year.Results: There were no statistically significant differences in terms of age and sex distribution, type of spondylolisthesis and pre–operation pain between groups (p>0.05). Comparison of the mean VAS scores of two groups over the whole study period showed a significant statistical difference (p–value0.05), although comparison of VAS at three points in time showed a mixed result. VAS scores showed no significant differences between two groups before surgery, the day after surgery and one year after surgery (p>0.05), but the difference of mean VAS scores between groups 6 months after surgery was statistically significant (p0.05). Analyzing the course of VAS scores over the study period showed a descending pattern for either of the groups (p0.0001).Conclusion: Both surgical fusion techniques (PLF & PLIF) showed to be effective in treating low grade degenerative and isthmic spondylolisthesis, but PLIF was related to better outcome with respect to pain control.

Background & Aim: Spondylolisthesis is a visible deformity in lumbosacral region with vertebral slip and fracture or other deformities of pars interarticularis. This study aims at investigating the characteristics of spondylolisthesis surgery in operated patients.Methods & Materials\Patients: This is a retrospective study which included all the patients who had undergone spondylolisthesis surgery by one same surgeon from 2006 to 2011. Demographic characteristics such as age, gender, and surgery information including type of spondylolisthesis, incision site, laminectomy site, foraminotomy site, fixation site of vertebra and site of vertebral disc evacuation were collected. The data were analyzed using SPSS (Version16).Results: 52 of 63 enrolled patients were women (82.5%) and 11 men (17.5%) with mean age of 49.6 years. Based on frequency, spondylolisthesis types were 60 degenerative (95.2%), 2 post–surgical (3.2%) and 1 post–traumatic (1.6%), respectively. 58 patients had spondylolisthesis only in one vertebra and 5 patients in two vertebrae. The total number of slipped vertebrae was 68, in which slip was seen in L3, L4 or L5 vertebrae. In 42 patients, laminectomy was performed only in one vertebra, in 19 patients in two vertebrae, in 1 patient in three vertebrae and in 1 patient in five vertebrae. The total number of vertebrae with foraminotomy was 106. The highest frequency of foraminotomy was seen in L5, L4, and S1 vertebrae, respectively. Except in one case, the rest 62 patients underwent fixation surgery in two or three vertebrae.Conclusion: Based on the results, the frequency of spondylolisthesis was approximately five times in women compared to men. The most common type was degenerative spondylolisthesis. Type of surgery was fixation with pedicle screw and fusion.

Background and Aim: Traumatic subdural hygroma is the accumulation of CSF (cerebrospinal fluid) in subdural space following head trauma. The mass effect of hygroma on brain can impinge on consciousness. There are still many ambiguities on indications of hygroma surgery. This is an 11–year follow–up study which involves the patients suffering traumatic subdural hygroma who underwent surgery.Methods & Materials\Patients: In this retrospective study, clinical records of 16 patients who were operated due to traumatic subdural hygroma were studied. The data from existing records in the hospital were collected and analyzed. They were then analyzed by Repeated Measures ANOVA using SPSS (Version 18). The differences were considered statistically significant at P≤0.05.Results: In this study, there were 13 men (81.3%) and 3 women (18.7%) (Mean age=62 years old). In 87.75% of patients, hygroma was diagnosed 6 days after head injury. It wasunilateral in majority of patients (56.3%) and located in fronto–parietal area (81.3%). The most frequent concomitant injuries were contusions (25%) and subarachnoid hemorrhage (18.8%), respectively. GCS trend on admission and at discharge was significantly different fromthat of hygroma formation (P0.05). One–fourth of patients had recurrence of hygroma after surgery. All patients (except one) had good outcome.Conclusion: Subdural hygroma is a delayed lesion and surgical treatment improves the level of consciousness (LOC) in afflicted patients.
