Öğe Arthroscopic-assisted surgical treatment for developmental dislocation of the hip before the age of 18 months(SPRINGER, 2013) Ozturk, Hayati; Oztemur, Zekeriya; Bulut, Okay; Tezeren, Gunduz; Bulut, SemaThe purpose of this study is to evaluate the results of arthroscopy assisted surgical treatment of developmental dislocation of the hip (DDH). Arthroscopic assisted surgical treatment was performed on nine hips of nine female children with DDH using our method, published previously, between January 2001 and December 2005. Their ages ranged from 9 to 16 months. Percutaneous adductor tenotomies were performed in seven cases. A spica cast and abduction splint were used for 11-17 weeks postoperatively. Acetabular index and Shenton line were used for preoperative and postoperative radiologic evaluation. Also, the cases were evaluated postoperatively with respect to range of motion restriction, and the leg length discrepancy. The average follow-up was 47.7 months (range 22-79 months). Acetabular index measurements of cases in the preoperative/postoperative periods were as follows: preoperative mean angle 39.9A degrees (range 34A degrees-52A degrees)/postoperative mean angle 26A degrees (range 22A degrees-34A degrees). Hip joint restriction and leg length discrepancy were not observed postoperatively. However, two patients had acetabular dysplasia. Acetabular dysplasia was completely resolved in one patient in the third year of follow-up, whereas Salter innominate osteotomy, required in another patient, was in the second year of follow-up. The latter patient was the oldest case (16-month-old) in our series. Based on the results of this study, treatment of developmental hip dysplasia with arthroscopic-assisted surgical treatment technique may be safe and effective method. Further clinical studies will be required to confirm this study.Öğe Contribution of Lumbar Vertebral Magnetic Resonance Imaging to Diagnosis in Women with Osteoporosis(Galenos Publ House, 2022) Atik, Irfan; Atik, Seda; Gul, Enes; Bulut, SemaObjective: The aims of this study are to compare bone mineral densitometry and magnetic resonance imaging (MRI) findings in postmenopausal women diagnosed with osteoporosis and the investigation of the effectiveness of MRI in the diagnosis of osteoporosis. Materials and Methods: Forty female patients, 50 years of age or older who underwent lumbar MRI examination and were diagnosed with dual-energy X-ray absorptiometry (DEXA) osteoporosis were included in our study. Forty healthy women aged 20-29 years with lumbar MRI examinations were included in the control group. On sagittal T1-weighted (T1W) images of individuals in the patient and control groups signalto-noise ratio (SNR) was measured from L1-L4 vertebrae. To facilitate the diagnosis of osteoporosis, a quantitative score called the M-score was obtained using SNR values. The relationship between DEXA and the obtained SNR and M-score values were investigated. Results: In the patient group, median SNR values of L1, L2, L3, L4 vertebrae obtained from T1-weighted sequence was 57.49 (25.18-182.48), and they were 24.90 (7.40-41.70) in the control group. Receiver operating characteristics analysis was performed for L1, L2, L3, L4 vertebrae. The area under the curve for the mean value of L1-L4 vertebra was found to be 0.966 (p < 0.001), and the 95% confidence interval was found 0.933-1.000. The mean SNR predictive value of L1-L4 was calculated as 33.45, and sensitivity for this value was found to be 90%, and specificity was found to be 90%. There was a negative correlation between lumbar MRI SNR-DEXA (p > 0.05) and M score-DEXA (p > 0.05). Conclusion: It has been concluded that L1-L4 vertebral SNR measurement in T1-weighted sequence in lumbar MRI can be used to distinguish osteoporosis patients from normal individuals. Thus, osteoporosis can be diagnosed without X-ray exposure.Öğe CT Assessment of Bone Remodeling in the Otic Capsule in Chronic Renal Failure: Association With Hearing Loss(AMER ROENTGEN RAY SOC, 2013) Erkoc, Mustafa Fatih; Bulut, Sema; Imamoglu, Hakan; Gumus, Cesur; Kayatas, MansurOBJECTIVE. Hearing loss (HL) is common in patients with chronic renal failure (CRF), but its cause is controversial. The aim of this study was to determine the effect of CRF on the bone density of the otic capsule using densitometric measurements with MDCT and to evaluate the relationship between changes in the otic capsule density and HL in patients with CRF. MATERIALS AND METHODS. The study included 34 patients with nonsyndromic CRF undergoing hemodialysis and 35 healthy control subjects. A CT was obtained, for a variety of reasons, in control subjects who did not have CRF or HL, but patients with trauma and infection were excluded. Control subjects were chosen on the basis of a normal CT and pure tone audiometry findings. Densitometric measurements were made using CT in the region anterior to the oval window and anterior to the internal auditory canal. These measurements were compared between patients and control subjects. Pure tone audiometry was performed to detect HL. The average levels of parathyroid hormone in the previous 6 months and the duration of hemodialysis in patients were documented. The association between the levels of parathyroid hormone, the duration of hemodialysis, and the region-of-interest density values in the patient groups were evaluated using the Pearson correlation coefficient. RESULTS. HL was found in 40 of 68 ears (58.8%) in the patient group. A significant difference in the otic capsule density was found between the ears with and without HL. There was a strong negative correlation between the parathyroid hormone level and the densitometric measurement of the otic capsule. CONCLUSION. There is osseous remodeling of the otic capsule in CRF with loss of bone density, and this is associated with HL in CRF.Öğe Evaluation of the prevertebral soft tissue thickness by magnetic resonance imaging in patients with mild neck problem(Turkish Neurosurgical Society, 2013) OztUrk, Ibrahim; Bulut, Sema; Atalar, Mehmet H.; Salk, Ismail; Ozum, UnalAim: We encountered no study conducted on the evaluation of prevertebral soft tissue (PVST) thickness by magnetic resonance imaging (MRI) during our literature search. Measuring PVST thickness by MRI in the cervical region of adult cases was aimed in the present retrospective study. MaterIal and Methods: For the intended purpose, a total of 136 patients, composed of both males and females, with ages ranging from 20 to 69 years, in whom no pathology in the cervical prevertebral region was revealed by MRI modality implemented for various reasons, were included in the study. Results: The upper limit of normal for PVST thickness was measured in our study to be 10 mm, 7 mm and 20 mm at C1, C2-C3 and C6-C7 vertebral levels, respectively. The least variation in the measurements and standard deviations were obtained at C3-C4 vertebral levels. Upon making a comparison between the measured PVST thicknesses on the basis of gender, the measurements at C2,C4 and C7 were found to display significant difference, whereas that was not the case for the measurements obtained at the other levels. ConclusIon: Progressively widespread use of MRI for the traumas inflicting the cervical region makes it obligatory to specify normal values for the thickness of PVST measured by MRI.Öğe Fetal distal femur epifiz ossifikasyon çekirdeğinin gebelik yaş tayinindeki yeri(Cumhuriyet Üniversitesi, 1991) Bulut, Sema; ,ÖZET Cumhuriyet Üniversitesi Sağlık Hizmetleri Uygulama ve Araştırma Hastanesi Radyodiagnostik Anabilim Dalına Ocak 1991 ile Eylül 1991 tarihleri arasında obstetrik US için başvuran 128 gebe, gebelik yaş tayini için incelendi.
