Öğe Is success objective or subjective in knee prosthesis?(Yerkure Tanitim & Yayincilik Hizmetleri A S, 2009) Copuroglu, Cem; Ozcan, Mert; Aykac, Bilal; Yilmaz, Baris; Yalniz, ErolObjective: To analyze the relation between the radiological and functional results and satisfaction of the knee prosthesis. Material and Methods: In this study, knee prosthesis applied to 43 patients' 76 knees were retrospectively evaluated. As a radiologic parameter; anatomical alignment, and as a functional measurement; range of motion was evaluated. Visual analogue scale (VAS) was measured as a pain score. The relation of functional and radiological measurements with VAS scores was analyzed. All the patients were re-evaluated with Oxford knee score. Results: Study group included 37 women and 6 men with a mean age of 63 (26-76). A total number of 76 knees (33 bilateral, 10 unilateral) were evaluated. Mean follow up time was 16.25 months (2-29 months). In the last evaluation; according to the preoperative evaluation, varus deformity improved, functional improvement could not be gained and VAS decreased, in 23 knees. In 21 knees, no radiological and functional improvement could be gained, VAS decreased. In 13 knees, no radiological difference was obtained, functions got worse, VAS decreased. In 3 knees, no radiological difference was obtained, functions were better, VAS decreased. Three knees were radiologically worse, without any change in functions, VAS decreased. In 2 knees, radiological and functional results improved, VAS decreased. In 2 knees, although there was postoperative infection, VAS decreased. In only 3 knees, radiological and functional results were worse and VAS score did not change. Mean Oxford knee score was 9.7. Conclusions: Although radiological and functional results are not so good, application of the knee prosthesis decreases the patients' pain and increases the patients' satisfaction.Öğe Magnetic resonance imaging predictors of surgical outcome in degenerative lumbar spinal stenosis(Springer, 2012) Alicioglu, Banu; Yilmaz, Baris; Bulakbasi, Nail; Copuroglu, Cem; Yalniz, Erol; Aykac, Bilal; Urut, Devrim UlasTo identify any MRI predictors for surgical outcomes of patients with degenerative lumbar spinal stenosis (DLSS) having instrumented posterior decompression (IPD) surgery. Seventy patients with DLSS who underwent IPD were reviewed retrospectively. The clinical score of each patient was assessed using the JOAS (Japanese Orthopedics Association Scoring) system, which is mainly based on the subjective symptoms and physical signs of the patients before (JOAS-I) and after (JOAS-II) surgery. Healing rate (HR) was calculated as: [(JOAS-II) - (JOAS-I)] x 100/[15 - (JOAS-I)]. HR > 50 % was considered clinical improvement. Radiological stenosis was assessed on MRI and was graded from 0 to 3 at the laminectomy level in terms of thecal sac-nerve root compression, foraminal stenosis, and facet degeneration. Mean HR of the improved patients (n = 39) was 81.94; HR of the unimproved patients (n = 31) was 34.75 (p < 0.05). There was no statistical difference in radiological stenosis parameters between the two groups (p > 0.05). HR was worse in patients with severe facet degeneration. Surgical outcomes of DLSS depend on multiple variables. It is not possible to predict the outcomes by assessing only one parameter. The possible outcomes should be analyzed by considering all the factors individually.Öğe Postoperative evaluation of quality of life in lumbar spinal stenosis patients following instrumented posterior decompression(Turkish Assoc Orthopaedics Traumatology, 2011) Aykac, Bilal; Copuroglu, Cem; Ozcan, Mert; Ciftdemir, Mert; Yalniz, ErolObjectives: Spinal stenosis is a clinical condition in which bone and soft tissues compress the spinal canal, neuronal foramina and nerve roots. In this study, we aimed to evaluate the effectiveness of surgical treatment on patient satisfaction. Our sample included 64 patients with degenerative lumbar spinal stenosis on whom posterior decompression and instrumentation was applied. Methods: In this retrospective study, files of 64 patients who underwent posterior decompression surgery with instrumentation for degenerative lumbar spinal stenosis between March 2004 and April 2008 were examined. Patients were evaluated with Japanese Orthopaedic Association (JOA) form, form of degenerative lumbar spinal stenosis and the most recent postoperative orthopedic inspection findings for a minimum of one year after surgery. Results: Mean age of patients was 59.9 years and mean follow-up was 27.9 months. When evaluated using the Japanese Orthopaedic Association form, postoperative scores in 63.5% of the patients improved. Based on this postoperative improvement; Japanese Orthopaedic Association scores were found statistically significant (p<0.001). Gender (p=0.651), age (p=0.192), with the length of complaint (p=0.095), time passed after surgery (p=0.933), number of laminectomy level (p=0.997), deformity before operation (p=0.773) and systemic disease were not statistically correlated with improvement based upon Japanese Orthopaedic Association scores (p=0.052). But Japanese Orthopaedic Association scores were found to have improved (83%) in cases with no systemic diseases. Conclusion: Our findings show that posterior decompression surgery with instrumentation is a useful treatment modality for patients with severe degenerative lumbar spinal stenosis. There is no secondary factor affecting improvement and instability after surgery is not observed in patient groups.Öğe Reliability of ultrasonographic measurements in suspected patients of developmental dysplasia of the hip and correlation with the acetabular index(Medknow Publications, 2011) Copuroglu, Cem; Ozcan, Mert; Aykac, Bilal; Tuncer, Beyti; Saridogan, KenanBackground: Ultrasonography is accepted as a useful imaging modality in the early detection of developmental dysplasia of the hip (DDH). Early detection and early treatment of DDH prevents hip dislocation and related physical, social, economic, and psychological problems. The purpose of this study was to evaluate the reliability of ultrasonographic and roentgenographic measurements measured by seven different observers. Materials and Methods: The alpha angles of 66 hips in 33 patients were measured using the Graf method by seven different observers. Acetabular index degrees on plane roentgenograms were measured in order to assess the correlation between the ultrasonographic alpha angle and the radiographic acetabular index, which both show the bony acetabular depth, retrospectively. Results: The interclass correlation coefficient, measuring the interobserver reliability, was high and statistically significant for the ultrasonographic measurements. There was a negative correlation between the alpha angle and the acetabular index. Conclusions: Ultrasonography, when applied properly, is a reliable technique between different observers, in the diagnosis and follow up of DDH. When assessed concomitantly with the roentgenographic measurements, the results are reliable and statistically meaningful.Öğe Simultaneous occurrence of acute posterior shoulder dislocation and posterior shoulder-fracture dislocation after epileptic seizure(Medknow Publications & Media Pvt Ltd, 2009) Copuroglu, Cem; Aykac, Bilal; Tuncer, Beyti; Ozcan, Mert; Yalniz, Erol[Abstract Not Available]
