Complications of 2-level dynamic stabilization: A correlative clinical and radiological analysis at two-year follow-up on 103 patients
Çıplak, Necati Mert; Süzer, Tuncer; Şentürk, Salim; Yaman, Onur; Sasani, Mehdi; Öktenoğlu, Tunç; Yılmaz, Atilla; Erbulut, Deniz Ufuk; Özer, Ali Fahir (Turkish Neurosurgical Society, 2018)AIM: To investigate the postoperative complications, such as screw loosening, screw breakage and adjacent segment disease (ASD), in patients who underwent surgery with 2-level dynamic stabilization systems. MATERIAL and ... -
Effect of U-shaped implant on the biomechanics of the cervical spine
Mümtaz, Muzammil; Zaferparandeh, İman; Taherzadeh, Paniz; Akıncı, Saliha Zeyneb; Erbulut, Deniz Ufuk (Institute of Electrical and Electronics Engineers Inc., 2016)Fusion has been a standard method of treatment for decades as it tends to reduce or eliminate the pain at the operated segment. However, this method has a drawback that it results in the increase of stress and range of ... -
Finite element analysis of cervical spine & finite element modeling of knee joint
Mumtaz, Muzammil (İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2017)Finite Element (FE) analysis allows predicting the behavior of real life systems in controlled environment. In the recent decades, FE modeling has gained significant attention of the medical industry as well. There is no ... -
Influence of three-dimensional reconstruction method for building a model of the cervical spine on its biomechanical responses: A finite element analysis study
Zafarparandeh, İman; Erbulut, Deniz Ufuk; Özer, Ali Fahir (Hindawi Publishing Corporation, 2016)In some finite element analysis studies of models of sections of the spine, the three-dimensional solid model is built by assuming symmetry about the mid-sagittal plane of the section, whereas in other studies, the model ... -
Investigation into cervical spine biomechanics following single, multilevel and hybrid disc replacement surgery with dynamic cervical implant and fusion: A finite element study
Mumtaz, Muzammil; Zafarparandeh, Iman; Erbulut, Deniz Ufuk (Multidisciplinary Digital Publishing Institute (MDPI), 2022)Cervical fusion has been a standard procedure for treating abnormalities associated with the cervical spine. However, the reliability of anterior cervical discectomy and fusion (ACDF) has become arguable due to its adverse ... -
Lumbar single-level dynamic stabilization with semi-rigid and full dynamic systems: A retrospective clinical and radiological analysis of 71 patients

Methods: A total of 71 patients underwent single-level ... -
Motion analysis study on sensitivity of finite element model of the cervical spine to geometry
Zafarparandeh, Iman; Erbulut, Deniz Ufuk; Özer, Ali Fahir (SAGE Publishing Ltd, 2016)Numerous finite element models of the cervical spine have been proposed, with exact geometry or with symmetric approximation in the geometry. However, few researches have investigated the sensitivity of predicted motion ... -
