    A new transodontoid fixation technique for delayed type II odontoid fracture: technical note
    (Elsevier Science Inc, 2009) Ozer, A. Fahir; Cosar, Murat; Oktenoglu, Tunc B.; Sasani, Mehdi; Iplikcioglu, A. Celal; Bozkus, Hakan; Bavbek, Cengiz
    Background: A different transodontoid screw fixation technique Was studied in delayed type II odontoid fractures. This study presents observations oil a different transodontoid fixation technique to remove and decrease the amount of sclerotic layers to accelerate the Fusion process after the operation. Methods: Ten cases of chromic type II odontoid fractures, were operated oil via transodontoid screw fixation between 2000 and 2007 which were admitted 6 weeks or later after the trauma. Four of these 10 delayed patients were operated oil using a new anterior transodontoid screw fixation technique, whereas the other 6 delayed patients were operated On using, classical anterior transodontoid screw fixation. Results: Four delayed cases with type It odontoid fracture operated oil via this new technique had good results throughout the minimum 38 months' follow-up period. We did not observe nonunion, infection, and/or other complications such as vascular or brain-stern injury. Conclusion: Transodontoid screw fixation should be considered as a preferable treatment modality. This surgical intervention may be all alternative to conservative treatment even for cases with delayed type II odontoid fractures. (C) 2009 Elsevier Inc. All rights reserved.

    Management of Type II Odontoid Fractures for Osteoporotic Bone Structure: Preliminary Report
    (Turkish Neurosurgical Soc, 2015) Cosar, Murat; Ozer, A. Fahir; Alkan, Bahadir; Guven, Mustafa; Akman, Tarik; Aras, Adem Bozkurt; Ceylan, Davut
    AIM: Anterior transodontoid screw fixation technique is generally chosen for the management of type II odontoid fractures. The nonunion of type II odontoid fractures is still a major problem especially in elderly and osteoporotic patients. Eleven osteoporotic type II odontoid fracured patients were presented in this article. MATERIAL and METHODS: We have divided 11 patients in two groups as classical and Ozer's technique.We have also compared (radiologically and clinically) the classical anterior transodontoid screw fixation (group II: 6 cases) and Ozer's transodontoid screw fixation technique (group I: 5 cases) retrospectively. RESULTS: There was no difference regaring the clinical features of the groups. However, the radiological results showed 100% fusion for Ozer's screw fixation technique and 83% fusion for the classical screw fixation technique. CONCLUSION; In conclusion, we suggest that Ozer's technique may help to increase the fusion capacity for osteoporotic type II odontoid fractures.

    The major complications of transpedicular vertebroplasty
    (Amer Assoc Neurological Surgeons, 2009) Cosar, Murat; Sasani, Mehdi; Oktenoglu, Tunc; Kaner, Tuncay; Ercelen, Omur; Kose, K. Cagri; Ozer, A. Fahir
    Object. Vertebroplasty is a well-known technique used to treat pain associated with vertebral compression fractures. Despite a success rate of up to 90% in different series, the procedure is often associated with major complications such as cord and root compression, epidural and subdural hematomas (SDHs), and pulmonary emboli, as well as other minor complications. In this study, the authors discuss the major complications of transpedicular vertebroplasty and their clinical implications during the postoperative course. Methods. Vertebroplasty was performed in 12 vertebrae of 7 patients. Five patients had osteoporotic compression fractures, I had tumoral compression fractures, and I had a traumatic fracture. Two patients had foraminal leakage, I had epidural leakage, I had subdural cement leakage, 2 had a spinal SDH, and the last had a split fracture after the procedure. Results. Three patients had paraparesis (2 had SDHs and I had epidural cement leakage), 3 had root symptoms. and I had lower back pain. Two of the 3 patients with paraparesis recovered after evacuation of the SDH and subdural cements however, I patient with paraparesis did not recover after epidural cement leakage, despite cement evacuation. Two patients with foraminal leakage and I with subdural cement leakage had root symptoms and recovered after evacuation and conservative treatment. The patient with the split fracture had no neurological symptoms and recovered with conservative treatment. Conclusions. Transpedicular vertebroplasty may have major complications, Such as a spinal SDH and/or cement leakage into the epidural and subdural spaces, even when performed by experienced spinal surgeons. Early diagnosis with CT and intervention may prevent worsening of these complications. (DOI: 10.3171/2009.4.SPINE08466)
