Different techniques were designed for atlantoaxial fixation as sublaminar wiring, transarticular screw fixation, and, recently, C1 lateral mass and C2 pedicle polyaxial screws and rod system. Purpose: To investigate the safety, advantages, and complications of posterior atlantoaxial fixation with polyaxial C1 lateral mass and C2 pedicle screws in C1-C2 instability. Study Design: A retrospective clinical case series. Patients and Methods: Fourteen consecutive patients, ten males and four females, with a mean age of 40.8±9.6 years were reported. All had traumatic C1-2 instability due to type II odontoid fractures and underwent posterior fixation with polyaxial C1 lateral mass and C2 pedicle screws. Nine patients suffered from motor vehicle accident (MVA) and 5 suffered from falls. All patients were neurologically intact except four patients who had neurological deficits. We used Japanese Orthopedic Association Score (JOA) for their functional evaluation. The average follow-up was 17±1.96 (range, 12–20 months). Operative time, operative blood loss, screw trajectory, screw length, and injury of neurovascular structures were reported. Fusion and construct stability were evaluated by plain radiography and/or CT. Visual Analogue Scale (VAS) of neck pain and JOA were used to evaluate the functional outcome. Results: The mean duration of surgery was 175.3±12.3 min. The mean blood loss was 553.6±106.5 ml and two patients required transfusion of one unit of blood. The mean length of C1 lateral mass and C2 pedicle screws were 30±1.6 mm and 16.4±1.8 mm, respectively. Correct screw placement and good stability were reported in all patients (100%) at the last follow-up. Mean neck pain on VAS was 2.8±0.8 and 2.3±0.5 at 6 and 12 months, respectively. The complications included moderate pain at iliac graft site for 3 months in 2 patients, pain and dysesthesia in C2 dermatome for 4 months in 3 patients, and superficial wound infection in 2 patients. Conclusion: Posterior atlantoaxial fixation with polyaxial C1 lateral mass and C2 pedicle screws is a safe and effective method in the treatment of traumatic atlantoaxial subluxation due to type II odontoid fractures.

Controversy about the number of levels involved in the fixation remains as the stability of the short-segment fixation remains questionable. Recently, it has been shown that application of intermediate screw in the fractured vertebra improves the biomechanical stability of the short-segment construct. \u0000Purpose: To compare the outcome of long-segment fixation (LSF) versus short-segment fixation with intermediate screws (SSFIS) in the management of the thoracolumbar burst fractures. \u0000Study Design: A prospective, nonrandomized clinical controlled trial. \u0000Patients and Methods: Fifty patients with thoracolumbar burst fracture (T11-L2) types A3 and A4 AOSpine classification with a Thoracolumbar Injury Classification and Severity (TLICS) scale of more than 4 were treated between 2009 and 2014 with posterior pedicle screw fixation. Patients were divided into two groups according to the number of instrumented levels. Group 1 included 25 patients treated with LSF (two levels above and two levels below the fractured level) while Group 2 included 25 patients treated by SSFIS (one level above and one level below with 2 intermediate screws in the fractured level). The patients were evaluated for local kyphotic angle (LKA) correction and maintenance, anterior vertebral body height (AVH) compression, and Visual Analogue Scale (VAS) for back pain and treatment related complications. Construct failure was defined as screw pullout or instrument breakage. \u0000Results: The two groups were similar with regard to age, sex, fractured levels, fracture type, TLICS score, preoperative local kyphotic angle, and anterior vertebral body height compression. Postoperative correction of the local vertebral compression assessed with LKA and AVH significantly improved in both groups compared to the preoperative degree. There was no significant difference in the two groups in early postoperative or follow-up regarding the degree of correction and its maintenance. No construct failure or major treatment related complication was encountered in both groups with significant reduction of VAS and ODI in both groups between early postoperative and late follow-up (13.5±2 months). \u0000Conclusion: Intermediate screw applied in the fractured level in management of thoracolumbar burst fracture improves the correction and maintenance of local kyphosis in short-segment fixation like long-segment construct with saving vertebral motion levels from being fixed. More randomized controlled and multicenter studies are needed to support these findings.

To a certain extent the surgeon can make use of 3D-fluoroscopy for intraoperative control of the implants. To ease this process, the surgeon can make use of the so-called cranial frame which is attached to the Mayfield clamp, in combination with navigated 3D-fluoroscopy. The use of the cranial frame for navigated anterior craniocervical approaches as in the case of transnasal procedures at the clivus and foramen magnum is quite widespread. In the literature, the use of this technique for spine approaches is limited to a few case reports. Purpose: To present the feasibility of 3D-fluoroscopy navigation in anterior cervical spine procedures with the use of cranial frame. Study Design: Retrospective clinical case cohort. Patients and Methods: We present our experience in the technique of navigation in 5 patients of anterior cervical spine procedures. Anterior instrumented fusion in the cervicothoracic spine was performed in 4 patients and in the last patient anterior C1/2 fixation was performed. We used a system composed of Arcadis Orbic 3D C-arm by Siemens Medical Solutions, Erlangen, Germany, for acquisition of 3D images and the Stealth Station system by Medtronic Inc., Louisville, USA, for navigation. We used a socalled cranial frame for navigation that is fixed to the Mayfield head holder; a preoperative 3D scan was performed in some patients. The intraoperative 3D scan was performed after removal of the retractors, and additional 3D scan was beneficial in some patients during the surgical procedure. Results: Navigation was helpful in identification of the entry points and trajectories of the screws especially in the cervicothoracic region with no need for fluoroscopy. Additional advantage of the use of this system is the possibility of performing intraoperative 3D scan after instrumentation to verify hardware placement. Conclusion: The illustrated cases demonstrate the advantages of 3D-fluoroscopy navigation with use of the cranial frame in the upper transitional zones. Disadvantages of this method are the complex intraoperative draping and logistics and the possible inaccuracy because of long distances and spinal mobility. Carbon Mayfield may facilitate positioning but is not mandatory.

Patients were treated with METRx system (Medtronic Sofamor Danek, Inc., Memphis, TN, USA), at Orthopedic Department, Zagazig University, between May 2012 and June 2015. Primary outcomes parameters included Numerical Rating Scale (NRS) for back and leg symptoms and Oswestry Disability Index (ODI) to quantify pain and disability, respectively. Secondary outcomes parameters included operative time, blood loss, preoperative and 3-month postoperative lumbar dynamic radiographs, and modified McNab criteria. Only patients who completed 36 months of follow-up were included in the final analysis of this study. Follow-up data were obtained from outpatient clinic follow-up visits by two independent physicians.Results: At the final follow-up, the improvement in claudicant leg pain and disability was statistically significant, and the endoscopic fenestration procedure did not affect the stability of the motion segment. The total success rate according to McNab criteria was 85.7% (30/35), fair 5.7% (2/35), and poor 8.6% (3/35). The mean NRS leg score significantly decreased from 7.3±1.5 preoperatively to 0.8±0.67 (P=0.001) postoperatively.

Fusion in Scheuermann kyphosis is a long fusion surgery that usually extends into the lumber spine leaving less mobile segments. Debate has focused on the selection of the LIV. Some recommend fusing into the SSV to decrease the incidence of DJK while others use the FLV which is just caudal to the first lordotic disc as the LIV to save more motion segments. Few studies recommend fusion into the vertebra just cephalic to the first lordotic disc (FLV-1).Study Design: A prospective clinical case study.Purpose: To evaluate the outcomes of fusing into the FLV-1 in surgical treatment of SK and whether it is associated with increased incidence of distal junctional failure and DJK or not.Patients and Methods: The study included 25 patients with SK treated by posterior-only surgery using all pedicular screw instrumentation with or without posterior release/Ponte osteotomies using the FLV-1 as the LIV.
