Öğe Cervical and thoracic/lumbar motion and muscle strength in surgically treated adolescent idiopathic scoliosis patients(IOS Press, 2022) Turan, Kayhan; Kara, Gökhan Kürşat; Çamurcu, Yalkın; Kızılay, Yusuf Onur; Uysal, Yunus; Şahin, Ecem; Aydınlı, UfukAbstract: BACKGROUND: To date, only one study assessed the spinal mobility and muscle strength of patients who were treated either with fusion or brace treatment. OBJECTIVE: The aim of this retrospective study was to evaluate the range of motion (ROM) and strength of the cervical and thoracic/lumbar spine in patients who underwent spinal fusion for the treatment of adolescent idiopathic scoliosis (AIS) in comparison to healthy individuals. METHODS: Patients (n= 28) who were treated surgically for AIS were included in the study. An age and gender matched control group (n= 22) was included that consisted of healthy individuals. DAVID® Lumbar/Thoracic Extension, Lumbar/Thoracic Rotation, and Cervical Extension/Lateral Flexion devices were used to measure cervical and lumbar/thoracic ROM as well as muscle strength. RESULTS: Significant differences were observed between groups in all ROM measurements except thoracic/lumbar sagittal flexion ROM measurement (p= 0.198). There were significant differences between groups in terms of muscle strength, except thoracic lumbar left rotation strength (p= 0.081). CONCLUSIONS: The findings of the current study demonstrated that cervical and thoracic/lumbar range of motion, as well as muscle strength, were significantly decreased in surgically treated adolescent idiopathic scoliosis patients compared to healthy counterparts. However, trunk (thoracic/lumbar) flexion range of motion and trunk left rotation muscle strength were not significantly different.Öğe Evaluation of the preferences of Turkish spine society members towards adolescent idiopathic scoliosis treatment(Galenos, 2020) Turan, Kayhan; Kara, Gökhan Kürşat; Çamurcu, İsmet Yalkın; Kızılay, Yusuf Onur; Uysal, Yunus; Aydınlı, UfukObjective: Controversies exist in the follow-up and treatment of adolescent idiopathic scoliosis (AIS). Thus, it is important to identify the attitudes of physicians from a national perspective to determine the status and problems associated with AIS treatment. This study aimed to evaluate the preferences of the Turkish Spine Society (TSS) physicians towards AIS treatment by investigating differences in AIS monitoring and treatment through a web questionnaire survey. Materials and Methods: This cross-sectional observational study employed a simple questionnaire focusing on AIS, which was created using Survey Monkey. Twenty questions, which were deemed as the most controversial topics of AIS, were constructed by the authors. A consensus was considered when 70% of the respondents provided the same answer. Results: A consensus was obtained among TSS physicians for using brace as conservative treatment and the brace was used 22 hours daily. Most TSS physicians agreed about the surgical indication of AIS; however, there was a disagreement about the indication of brace treatment. Conclusion: TSS physicians had a consensus on using brace in AIS treatment. However, there was a disagreement towards the indication of the brace treatment. The results demonstrated a consensus about surgical management and surgical experiences. However, a disparity existed about the time by which activities and contact sports are allowed.Öğe Is the Acetabular Cup Orientation Different in Robot-Assisted and Conventional Total Hip Arthroplasty With Right-Handed Surgeons Using an Anterolateral Approach?(Springernature, 2023) Kara, Gokhan Kursat; Turan, Kayhan; Eroglu, Osman Nuri; Ozturk, Cagatay; Ertuerer, ErdenIntroduction Total hip arthroplasty (THA) is one of the most successful orthopaedic procedures. Survival rates from 90% at 10 years to 93% at 20 years have been reported in different studies. Differences in implant and patient characteristics can undoubtedly explain some of this variability observed in prosthesis durability, but the effect of surgical technique and implant orientation cannot be ignored. Therefore, many intraoperative methods (anatomic landmarks, intraoperative x-ray, fluoroscopy, navigation, and robotic surgery) have been attempted to avoid acetabular component malpositioning. Although postoperative computed tomography (CT) is accepted as the gold standard for the measurement of acetabular anteversion, it remains controversial in respect of costs and radiation exposure. The aim of this study was to examine how acetabular component orientation was affected in robotic and conventional THA operations performed by two surgeons with right-hand dominance.Material and methods The study included 113 primary THA operations performed on 113 patients between 2017 and 2022 in two groups: (i) robotic THA (Mako, Stryker Corporation, Kalamazoo, Michigan, United States) (55 patients) and (ii) conventional THA (58 patients). The patients comprised 51 males and 62 females. THA was performed on 54 right-side hips and 59 left-side hips. The operations were performed by two orthopaedic surgeons, each with 20 years of arthroplasty experience, on all the patients in the lateral decubitus position with an anterolateral approach. In all the cases, the orientation of the acetabular component was 40 & DEG; inclination and 20 & DEG; anteversion. Difficult THA procedures (patients with developmental dysplasia of the hip (DDH), a history of hip surgery, revision THA, defect or deformity of the acetabulum, a history of scoliosis or lumbar posterior surgery, or those requiring proximal femoral osteotomy) were excluded from the study. Using the Liaw and Lewinnek methods, the acetabular component anteversion was measured on the radiographs taken in the optimal position postoperatively and the acetabular cup inclination angles were measured on the pelvis radiographs. The groups were compared using the Kolmogorov-Smirnov, Pearson Chi-square and Mann-Whitney U statistical tests. The limits were accepted as 40 & PLUSMN;5 & DEG; for inclination and 20 & PLUSMN;5 & DEG; for anteversion. Results No statistically significant difference was determined between the groups in respect of age, gender, or operated side. No statistically significant difference was determined between the optimal acetabular cup inclination angles of the robotic and conventional THA groups (p = 0.79). No statistically significant difference was determined between the optimal acetabular cup anteversion angles of the left and right conventional THA groups. Statistically significantly better results were determined in the robotic group in respect of acetabular cup anteversion (p<0,001). Conclusion The optimal orientation of the acetabular component is a key factor for successful THA. Otherwise, revision surgery is inevitable for reasons such as instability, impingement, or increased wear. The results of this study demonstrated that robotic surgery was superior to the conventional method in the placement of the acetabular component in the desired orientation.Öğe Monoaxial pedicle screws with sublaminar fixations in the correction of adolescent idiopathic scoliosis(Galenos Yayınevi, 2021) Turan, Kayhan; Kara, Gökhan Kürşat; Çamurcu, Yalkın; Kızılay, Yusuf Onur; Uysal, Yunus; Aydınlı, UfukObjective: To evaluate the radiological outcomes of posterior spinal instrumentation by using monoaxial pedicle screws with sublaminar fixations for the treatment adolescent idiopathic scoliosis (AIS). Materials and Methods: The data of 14 patients who underwent posterior instrumentation by using monoaxial pedicle screws with sublaminar fixations for the treatment of AIS between 2010 and 2019 were retrospectively analyzed. Patients’ age, gender, preoperative Risser classification, preoperative Lenke classification, and operative data were recorded through our medical records. Proximal thoracic (PT), main thoracic (MT), thoracolumbar/lumbar (TL/L) curve Cobb angles as well as thoracic kyphosis (TK) and lumbar lordosis (LL) Cobb angles were measured through preoperative and postoperative standing full spine X-rays. Results: The mean preoperative PT curve Cobb angle was 33.7 degrees, and it was 4 degrees postoperatively (p=0.068). The mean preoperative MT curve Cobb angle was 53.3 degrees and it was 8.7 degrees postoperatively (p=0.008). The mean preoperative TL/L curve Cobb angle was 43 degrees and it was 9.2 degrees postoperatively (p=0.005). The overall mean coronal plane correction ratio was 84%. The mean preoperative TK Cobb angle was 25.2±17.8 degrees and it was 32.9±8.9 postoperatively (p=0.101). Conclusion: According to the results acquired from this study, monoaxial pedicle screws with sublaminar fixations demonstrated an efficient correction in both PT, MT, and TL/L curves and restoration of TK in AIS surgery
