RESUMO
BACKGROUND: Subacromial impingement syndrome is one of the most common causes of painful shoulder in the middle-aged and elderly population. Coracoacromial ligament (CAL) degeneration is a well-known indicator for subacromial impingement. PURPOSE: To examine the relationship between CAL thickness on preoperative magnetic resonance imaging (MRI), arthroscopic CAL degeneration and types of rotator cuff tears. MATERIAL AND METHODS: Video records of patients who underwent arthroscopic shoulder surgery between 2015 and 2021 were retrospectively scanned through the hospital information record system. In total, 560 patients were included in this study. Video records of the surgery were used to evaluate the grade of coracoacromial ligament degeneration and the type of cuff tear. Preoperative MRI was used to measure CAL thickness, acromiohumeral distance, critical shoulder angle, acromial index, and acromion angulation. RESULTS: Significant differences were observed between grades of CAL degeneration in terms of CAL thickness (P < 0.001). As CAL degeneration increases, the mean of CAL thickness decreases. According to the results of post-hoc analysis, the mean CAL thickness of normal patients was significantly higher than those of patients with full-thickness tears (P = 0.024) and massive tears (P <0.001). Patients with articular-side, bursal-side, and full-thickness tears had significantly higher CAL thickness averages than patients with massive tears. CONCLUSION: This study showed that the CAL thickness decreases on MRI as arthroscopic CAL degeneration increases. High-grade CAL degeneration and therefore subacromial impingement syndrome can be predicted by looking at the CAL thickness in MRI, which is a non-invasive method.

Objective: To study red cell distribution width (RDW), RDW to platelet ratio (RPR) and mean platelet volume to platelet ratio (MPR), novel inflammatory markers of routine hemogram, of patients with or without dementia, according to the grade of the disease established by Fazekas's score in magnetic resonance imaging (MRI). Methods: A total of 1342 cases that undergone cranial MRI study were retrospectively analyzed. Patients without a previous stroke and over 45 years were enrolled in the study. Demographic and laboratory characteristics of the participants were obtained from institutional computerized database. Subcortical and periventricular white matter were evaluated in axial FLAIR images according to Fazekas's grading scale. Univariate and multivariate analysis were performed for assessing the predictors of Fazekas's grading scale. Results: MPR of Fazekas 0, Fazekas 1, Fazekas 2 and Fazekas 3 groups were 3, 3, 4 and 3%, respectively. MPR difference between study groups was not significant (p = .32). RPR of Fazekas 0, Fazekas 1, Fazekas 2 and Fazekas 3 groups were 6, 7, 7 and 7%, respectively. RPR difference between study groups was significant (p < .001). Conclusion: We suggest that increased RDW and RPR values may indicate higher Fazekas's score and dementia in cranial imaging studies. The radiologist should pay particular attention in interpretation of cranial MRI of these patients.

OBJECTIVES: The aim of this study is to evaluate the effects of performing computed tomography (CT) urogram in the prone position in terms of diagnosis. METHODS: CT urograms of 208 patients imaged randomly in the prone and supine positions were included in this study. A total of 199 patients and 370 collecting systems were examined in total. Axial raw data and reconstructed coronal thin and thick MIP images with a slice thickness of 5 mm were evaluated by 2 independent radiologists blinded to the initial diagnosis. Renal collecting system, ureters, and bladder were included in radiological evaluation. Anatomically, the renal collecting system was separated into 7 regions. Filling and dilatation of collecting systems were evaluated via images at urogram phase by scoring. RESULTS: Filling in lower pole infundibulum (p = 0.006), distal ureter (p = 0.006); and highly dilated lower pole calyx (p = 0.020), pelvis (p = 0.006), and bladder (p < 0.001) were determined to be better in images in the prone position compared to the supine position. There were no statistical differences in other regions. CONCLUSION: Better contrast material filling is achieved in dilated or non-dilated lower pole collecting system, dilated renal pelvis, non-dilated distal ureter of kidney, and in the bladder only by imaging the urogram phase in the prone position compared to the supine position. Additionally, presence of dilatation is a factor that could adversely affect filling. Studies in the future may investigate the contribution of prone positioning to CT urogram with larger series comparing it with other methods and modalities.

AIMS: Hemogram parameters in routine blood panels have been proposed as inflammation markers. These parameters, especially the red cell distribution width (RDW) and mean platelet volume (MPV), were evaluated as surrogate inflammatory markers in brain tumor patients. We aimed to observe RDW and MPV values of tumor patients and compare to those in healthy population. METHODS: We recorded white blood cell count, neutrophil count, lymphocyte count, hemoglobin, hematocrit, RDW, platelet count, and MPV of the study group at the time of diagnosis and compared to those of the control subjects. RESULTS: The RDW was significantly elevated in study group compared to that of the control subjects (p=0.001). The MPV was significantly lower in study group than that of the control group (p=0.01). CONCLUSION: Decreased MPV and increased RDW were both associated with brain tumor. However, prospective studies with larger sample sizes are needed to support the results and expose MPV and RDW variations between metastatic and primary brain tumors.

AIMS: We aimed to evaluate six months of results following repeated GON blocks. METHODS: We evaluated the results from GON block performed on 60 patients. Briefly, we applied a standard 2 mL of 0.5% Bupivacaine GON blockage once a week for 4 weeks. We recorded the Visual Analog Scale (VAS) scores, the number of migraine attacks and the Migraine Disability Assessment Questionnaire (MIDAS) scores. The study subjects were not allowed to use medication for prophylaxis, and Ibuprofen (400 mg, 1200 mg at maximum) was prescribed for any migraine attacks. RESULTS: The initial mean number of attacks per month before starting treatment was 8.33+2.31. After treatment, the initial MIDAS mean was found to be 2.82 per month; this declined to 1.47 in 3rd, and was 1.50 in the 6th month. The individual month values were found to be significant, and were listed respectively as, 1st month: 3.95+2.52, 2nd month: 3.23+1.82, 3rd month: 2.60+1.90, 4th month: 2.68+2.10, 5th month: 2.58+1.90 and 6th month: 2.58+1.90. The mean VAS scores were recorded as follows for each month: 6.28±1.24, 3.13±0.97, 2.55±1.19, 2.35±1.26, 2.38±1.20 and 2.48±1.30, respectively. This difference was noted to be statistically significant. No difference regarding the efficacy of the treatment was determined when the results were compared across age groups. CONCLUSION: We assume that GON blockage with 2 mL of 0.5% Bupivacaine can be a supportive treatment in migraine treatment, with no serious adverse effects reported.

BACKGROUND AND PURPOSE: Lumbar disc herniation (LDH) causes major disabilities worldwide. Several studies in the literature had reported the correlation between radiculopathy and inflammatory markers. Mean platelet volume (MPV), red cell distribution width (RDW) and neutrophil to lymphocyte (N/L) ratio are parameters of hemogram which have been found to be associated with inflammatory conditions. Purpose - Since inflammation has an important role in lumbar disc hernias, and RDW, MPV and N/L ratio are also known to be in correlation with inflammation, we have investigated these parameters of the patients with lumbar disc hernias and compared them with the results of the healthy subjects. METHODS: Our study group was composed of patients with lumbar disc hernia, whereas the control group was consisted of healthy volunteers whom visited our outpatient clinics for a routine check-up. Patient characteristics and hemogram parameters of the study cohort were obtained from computerized database system of our institution. SPSS software (SPSS 15.0 for Windows, Chicago, IL, USA) was used for the analysis. RESULTS: There was no significant difference between study and control groups in terms of WBC, neutrophil count, lymphocyte count, neu\lym ratio, Hb, Htc, MCV, and PLT levels (all p>0.05). RDW was significantly increased in study group [15.6 (12.3-22.5)] when compared to control group [14.5(11.9-16.3)] (p=0.004). And MPV in the study group [9.25 (6.38-14.5)] was also significantly increased in comparison to the control subjects [8.8 (6-10.1)] (p=0.013). CONCLUSION: In this retrospective study, we found that, RDW and MPV values in hemograms were increased in patients with lumbar disc herniation when compared to the control group. Conclusions - We suggest that, elevated RDW and MPV may help physicians in decision taking to order radiological imagings in patients with symptoms which can be associated with possible LDH diagnosis. However, for the sake of precision, prospective studies with larger populations are needed.

UNLABELLED: Hepcidin is a regulator of iron balance that is increased in obesity. It reduces the absorption of iron, reduces the transfer of iron from macrophages to the plasma and/or prevents mobilisation of stored iron. Obese patients with non-alcoholic fatty liver disease (NAFLD) demonstrate adipokine and cytokine release promoting inflammatory response. We aimed to analyse the hepcidin levels and iron metabolism in obese children with and without NAFLD and non-obese healthy controls. The study population consisted of 110 children aged 7-18 years in three groups: 50 obese patients without NAFLD, 30 obese patients with NAFLD, and 30 non-obese healthy controls. Serum hepcidin, ferritin, and iron levels, iron-binding capacity, lipid profile, and liver function tests were measured, and hepatic ultrasonography was performed in all participants. Obese patients' white blood cell counts, total cholesterol, triglyceride levels, and homeostatic model assessment of insulin resistance (HOMA-IR) were significantly higher than those of the control group. Iron-binding capacity was significantly higher in obese patients without NAFLD compared with obese patients with NAFLD (p = 0.002). Hepcidin levels were not significantly different between obese patients and the control group. However, hepcidin levels in obese patients with NAFLD were significantly higher than those in obese patients without NAFLD (p < 0.001). CONCLUSIONS: Hepcidin levels were significantly higher in obese children with NAFLD than those without NAFLD. Obese children with NAFLD should receive attention regarding iron metabolism disorders. Serum hepcidin could be a marker of iron metabolism status and NAFLD in these groups of patients.

PURPOSE: In this case-control study, we aimed to evaluate how muscle volume affects pelvic floor function by analyzing the levator ani muscle (LAM) using volumetric segmentation in addition to standard magnetic resonance (MR) defecography assessments. METHODS: We enrolled 85 patients with varying degrees of pelvic floor dysfunction (PFD) and 85 age- and gender-matched controls in this retrospective study. All patients had MR defecography images, while all controls had pelvic MR images obtained for other reasons. Group comparisons were performed using independent samples t-tests and Mann-Whitney U tests. The receiver operating curve (ROC) was constructed to establish a cut-off value for a normal LAM volume. Interrater reliability was assessed by calculating the intraclass correlation coefficient. A P value of less than 0.05 was considered statistically significant. RESULTS: Volumetric measurements revealed that the control group had higher LAM volumes, and the ROC curve analysis indicated a cut-off value of 38934.3 mm3 with a sensitivity of 0.812 and specificity of 0.8 for PFD assessment using LAM volumetric measurement. Gender did not significantly affect LAM volume in the control group. CONCLUSION: Alongside the useful structural and functional information acquired from MR defecography images, volumetric analysis, and three-dimensional reconstructions of LAM may help to improve the accuracy of the diagnosis.

There are many studies on the effects of temporal bone anatomical variations on a mastoid pneumatization. Considering the effects of the anatomic variations on mastoid pneumatization, it is considered that many anatomic variations may affect graft success rates and postoperative hearing threshold gains. We aimed to evaluate the effects of various anatomic variations on postoperative hearing gains among patients undergoing tympanoplasty. This retrospective cohort study conducted in a tertiary-care university hospital. This study enrolled 57 patients who underwent primary type 1 tympanoplasty operation using the temporal muscle fascia. The patients were divided into two groups as those with an anteriorly located sigmoid sinus (group 1), and no anatomic variation (group 2). Airway gain values at the frequency range of 250 Hz-8000 Hz and pure tone average (PTA) value were calculated preoperatively and at postoperative sixth month. The gains attained by the patient groups with anatomic variations were compared with group 2. There were significant differences between Group 1 and Group 2 in terms of the airway frequencies of 250, 500, 2000, 4000 Hz, and PTA value. We detected a lesser postoperative hearing gain in patients with an anteriorly located SS. We believe that anatomic variations that may affect middle ear and mastoid cavity may also affect postoperative hearing gain.
RESUMO
BACKGROUND: After a case of stroke, intracranial pressure (ICP) must be measured and monitored, and the gold standard method for that is through an invasive technique using an intraventricular or intraparenchymal device. However, The ICP can also be assessed through a non-invasive method, comprised of the measurement of the optic nerve sheath diameter (ONSD) through ultrasound (US). OBJECTIVE: To evaluate the ICP of patients who underwent wide decompressive craniectomy after middle cerebral artery (MCA) infarction via preoperative and postoperative ONSD measurements. METHODS: A total of 17 patients, aged between 34 and 70 years, diagnosed with malignant MCA infarction with radiological edema and mid-line shift, who underwent decompressive surgery, were eligible. From the records, we collected data on age, sex, preoperative and postoperative Glasgow Coma Scale (GCS) scores, National Institutes of Health Stroke Scale (NIHSS) score, the degree of disability in the preoperative period and three months postoperatively through the scores on the Modified Rankin Scale (MRS), and the preoperative and postoperative midline shift measured by computed tomography (CT) scans of the brain. RESULTS: Preoperatively, the mean GCS score was of 8 (range: 7.7-9.2), whereas it was found to be of 12 (range 10-14) on the first postoperative day (p = 0.001). The mean preoperative NIHSS score was of 21.36 ± 2.70 and, on the first postoperative day, it was of 5.30 ± 0.75 (p < 0.001). As for the midline shift, the mean preoperative value was of 1.33 ± 0.75 cm, and, on the first postoperative day, 0.36 ± 0.40 cm (p < 0.001). And, regarding the ONSD, the mean preoperative measurement was of 5.5 ± 0.1 mm, and, on the first postoperative day, it was of 5 ± 0.9 mm (p < 0.001). CONCLUSION: The ocular US measurement of the ONSD for the preoperative and postoperative monitoring of the ICP seems to be a practical and useful method.
ANTECEDENTES: Após um acidente vascular cerebral (AVC), a pressão intracraniana (PIC) deve ser medida e monitorada, e o método padrão-ouro para isso é um procedimento invasivo por meio de um dispositivo intraventricular ou intraparenquimal. No entanto, a PIC também pode ser avaliada por um método não invasivo, composto da medida do diâmetro da bainha do nervo óptico (DBNO) por ultrassom (US). OBJETIVO: Avaliar a PIC de pacientes submetidos a craniectomia descompressiva ampla após infarto da artéria cerebral média (ACM) por meio das medidas do DBNO nos períodos pré e pós-operatório. MéTODOS: Um total de 17 pacientes, com idades entre 34 e 70 anos, diagnosticados com infarto maligno da ACM com edema radiológico e deslocamento da linha média, e que foram submetidos a cirurgia descompressiva, eram elegíveis. A partir dos prontuários, coletamos informações relativas à idade, gênero, pontuações pré e pós-operatória na Escala de Coma de Glasgow (ECG), pontuação na escala de AVC dos National Institutes of Health (NIH), o grau de incapacidade no pré-operatório e após três meses da operação pelas pontuações na Escala de Rankin Modificada (ERM), e o desvio da linha média no pré e pós-operatório medido por tomografia computadorizada (TC) cerebral. RESULTADOS: No pré-operatório, a pontuação média na ECG foi de 8 (variação: 7,79,2), e, no primeiro dia do pós-operatório, 12 variação 1014) (p = 0,001). A pontuação média na escala dos NIH foi de 21,36 ± 2,70 no pré-operatório, e de 5,30 ± 0,75 no primeiro dia de pós-operatório (p < 0,00 1). Quanto ao desvio da linha média, no pré-operatório ele teve uma média de 1,33 ± 0,75 cm, e de 0,36 ± 0,40 cm no primeiro dia de pós-operatório (p < 0,001). E o DBNO apresentou uma média pré-operatória de 5,5 ± 0,1 mm, e de 5 ± 0,9 mm no primeiro dia de pós-operatório (p < 0,001). CONCLUSãO: A mensuração ocular do DBNO por US para o monitoramento da PIC no pré e no pós-operatório parece ser um método prático e útil.

OBJECTIVES: This study aimed to compare the lumbar lordosis (LL) and spinopelvic parameters of patients with stage 1-2 spondylolisthesis to those of the normal population and demonstrate the importance of these parameters in sagittal balance. METHODS: The lumbosacral parameters on the lateral radiographs of a total of 125 patients were retrospectively compared. Lumbosacral parameters including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis angle (LLA), L5 incidence (L5I), L5 slope (L5S), and sacral table angle (STA) were compared between groups. RESULTS: Comparison of the parameters between groups revealed no sex-based differences (p > 0.05). CONCLUSIONS: Abnormal sagittal spinopelvic parameters are commonly examined for their effects on the development of spondylolisthesis and should be used in routine practice. We found that the low SS values in our study, unlike those of other similar studies, may be a compensatory mechanism developed to reduce pain and maintain sagittal balance. Level of Evidence II; retrospective study.
OBJETIVO: Nosso objetivo é comparar os valores dos parâmetros de LL e espinopélvicos de pacientes com espondilolistese estágios 1 e 2 com a população normal e mostrar a importância desses parâmetros com relação ao balanço sagital. MÉTODOS: As radiografias laterais de um total de 125 pacientes foram avaliadas comparativa e retrospectivamente quanto aos parâmetros lombossacrais. Os parâmetros usados para a avaliação foram IP, InP, IS, ângulo de lordose lombar (ALL), incidência de L5 (In-L5), inclinação L5 (I-L5) e ângulo do platô sacral (APS). RESULTADOS: Os parâmetros lombossacrais IP, InP, IS, ALL, incidência de L5, I-L5 e APS foram comparados entre os grupos controle e espondilolistese. Quando cada parâmetro foi comparado entre homens e mulheres para avaliar o efeito do sexo nos grupos espondilolistese e controle, não houve diferença significativa entre as medidas de ambos os sexos (p > 0,05). CONCLUSÕES: Os parâmetros sagitais espinopélvicos anormais são usados comumente no presente por seus efeitos sobre o desenvolvimento da espondilolistese e devem fazer parte da prática de rotina. Segundo as avaliações, os baixos valores de IS em nosso estudo, que diferiram de estudos similares, podem ser um mecanismo de compensação desenvolvido pelos pacientes para reduzir a dor e manter o equilíbrio sagital. Nível de Evidência II; Estudo retrospectivo.
RESUMO
Tailgut cyst (cystic hamartoma) is a rare congenital pathology that arises -from post-natal primitive gut remnants in the retrorectal-presacral space. Because of the rarity of the lesion and the variability of the anatomical position, its diagnosis and surgical treatment are often difficult. Complete surgical excision of the multilocular and multicystic process prevents recurrent draining sinuses and eliminates the possibility of malignant change. We describe a case in which a tailgut cyst localized in the retrorectal and presacral space was characterized by abscess, repeated urinary tract infection, and rectal pain.

OBJECTIVE: To assess role of some inflammatory mediators in patients with primary and recurrent lumbar disc herniation. Expression of IL-6, transforming growth factor (TGF)-1, insulin-like growth factor (IGF)-1, and Bcl-2-associated X protein (BAX) have been shown to be more intense in the primary group than the recurrent goup, but this mediators may be important aspects prognostic. METHODS: 19 patients underwent primary and revision operations between June 1, 2009 and June 1, 2014, and they were included in this study. The 19 patients' intervertebral disc specimens obtained from the primary procedures and reoperations were evaluated. Expression of IL-6, TGF-1, IGF-1, and BAX were examined immunohistochemically in the 38 biopsy tissues obtained from the primary and recurrent herniated intervertebral discs during the operation. RESULTS: For IL-6 expression in the intervertebral disc specimens, there was no difference between the groups. The immunohistochemical study showed that the intervertebral disc specimens in the primary group were stained intensely by TGF-1 compared with the recurrent group. Expression of IGF-1 in the primary group was found moderate. In contrast, in the recurrent group of patients was mild expression of IGF-1. The primary group intervertebral disc specimens were stained moderately by BAX compared with the recurrent group. CONCLUSION: The results of our prognostic evaluation of patients in the recurrent group who were operated due to disc herniation suggest that mediators may be important parameters.
RESUMO
High social awareness of breast diseases and the rise in breast imaging facilities have led to an increase in the detection of even rare benign and malignant breast lesions. Breast lesions are associated with a broad spectrum of imaging characteristics, and each radiologic imaging technique reflects different characteristics of them. We aimed to increase familiarity of the radiologist with these uncommon lesions as well as correlate histopathologic findings with the radiologic imaging features of the tumors. Histopathologic examination is necessary in the evaluation of such breast lesions, particularly when radiologic images are not definitive for a specific diagnosis.

RESUMO
OBJECTIVES: Chronic inflammation and endothelial dysfunction are the characteristic features of Behçet's disease (BD). We researched carotid extra-medial thickness (cEMT), a novel ultrasound parameter for atherosclerotic vessel wall changes, and carotid intima media thickness (cIMT), a widely accepted marker of subclinical atherosclerosis, in patients with BD, and we evaluated the relationship between these two parameters. MATERIALS AND METHODS: In total, 31 patients with BD were matched to 26 control subjects based on age, gender, and major cardiovascular risk factors. Laboratory parameters, including lipid profile, were measured for both patients and controls. B-mode ultrasonography was used to assess the cEMT and cIMT. RESULTS: There was no significant difference in the cEMT values between the patients with BD and the control group (P = 0.90). cIMT in the BD group was significantly higher compared with the control group (P = 0.021). There was a significant positive correlation between cIMT and cEMT (r = 0.585, P = 0.001). Both cEMT and cIMT were positively correlated with age and the presence of arthritis. There was linear correlation with sedimentation, C-reactive protein, and cEMT. CONCLUSIONS: To the best of our knowledge, this is the first study to evaluate both cEMT and cIMT in BD. This study presents morphological evidence of subclinical atherosclerosis in terms of cIMT. Although there was no significant increment in cEMT, it has the potential to assess endothelial dysfunction in BD. Further studies are required to confirm this finding.

PURPOSE: The aim of this study was to evaluate prognostic importance of interleukin-6 (IL-6), matrix metalloproteinase (MMP)-1, insulin-like growth factor (IGF)-1, and Bcl-2-associated X protein (BAX) levels in biopsy specimens taken from the intervertebral disk specimens and the posterior longitudinal ligaments of patients with sciatic pain. METHODS: The specimens of the intervertebral disk and the posterior longitudinal ligament were obtained from 52 patients undergoing herniectomy and diskectomy at the Neurosurgery Department of the Abant Izzet Baysal University Izzet Baysal Training and Research Hospital between April 2012 and February 2014. The immunohistochemical expressions of IL-6, MMP-1, IGF-1, and BAX were evaluated in three categories: mild, moderate, and intense. RESULTS: The IL-6 expression in the intervertebral disk specimens was intense in the sequestration group when compared with that of the "protrusion" and "extrusion" groups. The intervertebral disk specimens in "extrusion" and "sequestration" groups were stained intensely for MMP-1. The IGF-1 expression was stained intensely in the intervertebral disk tissue of the extrude group patients. For the "extrusion" and "sequestration" groups, the intervertebral disk specimens were stained intensely for BAX compared with the protrude group. The IL-6 expression in the posterior longitudinal ligament specimens was more intense in the "sequestration" and "extrusion" groups when compared with that of the protrude group. The MMP-1 expressions were milder in the sequestration group when compared with that of the "extrusion" and "protrusion" groups. CONCLUSIONS: Our findings suggest that the cytokines, enzymes, growth factors, and proapoptotic proteins, such as IL-6, MMP-1, IGF-1, and BAX, may be critical factors in the pathophysiology of the degeneration of the intervertebral disks in patients with symptomatic degenerative disk disease.

AIM: To compare the safety and efficacy of spinal anesthesia (SA) in patients undergoing lumbar microdiscectomy (LM). MATERIAL AND METHODS: We evaluated 180 patients who underwent LM between 1 January 2012 and 5 July 2013. Demographic, clinical, laboratory, and pre-, intra-, and postoperative information was determined from the patients' medical records. RESULTS: Total anesthetic times were longer in the general anesthesia (GA) group. There was less bleeding at the surgical site in the SA group. Intraoperative blood pressure was significantly also lower in the SA group. Meanwhile, tachycardia was significantly higher in the GA group. The analgesic requirement in post-anesthesia care unit (PACU) was higher in the general anesthesia group. At PACU admission, analgesic requirement, heart rate, and the mean arterial pressure were higher in the GA group. Postoperative nausea and vomiting was more frequent among patients recovering in general anesthesia group. SA patients had an increased incidence of urinary retention compared with GA patients. Pulmonary complications requiring specific treatment were insignificantly higher among GA patients. CONCLUSION: In patients who undergo lumbar disc surgery, SA is a good alternative for experienced surgeons because of a more comfortable healing process.

OBJECTIVES: Lumbar spinal stenosis (LSS) in the elderly may result in a progressive narrowing of the spinal canal leading to compression of nerve roots in some individuals. The aim of this study was to evaluate the quality of life changes after minimally invasive decompression surgery without instrumentation in geriatric patients with lumbar spinal stenosis. PATIENTS AND METHODS: This prospective clinical study included 37 patients with American Society of Anesthesiologists (ASA) II-III scores between the ages of 65 and 86 years, who were planned to undergo surgical intervention due to LSS. All patients had neurogenic claudication and pain in the hips, thighs, and legs. Measurements of the osseous spinal canal were evaluated by magnetic resonance imaging. Before the surgical intervention, patient demographics and clinical characteristics were recorded. The Short-Form-36 test, the Oswestry Disability Index, and the Visual Analog Scale were applied to all patients preoperatively and two years postoperatively. RESULTS: In the study population, 11 patients had single level of spinal stenosis, 20 patients had two levels of spinal stenosis, and six patients had three levels of spinal stenosis. There were significant differences between the preoperative and postoperative ODI and VAS scores. There was a statistically significant difference in all subscales of the SF-36 test with the exception of general health scores. Three patients who had dural damage during the operation were treated with bio glue. Also, no patients were recorded to have any neurological deficits and root injuries postoperatively. CONCLUSION: Minimally invasive decompression surgery, without instrumentation, for lumbar spinal stenosis in geriatric patients significantly improves the patients' quality of life.
