Purpose: Defective posterior spinal arch and paraspinal musculature lead to progressive kyphosis in patients with myelomeningocele. Kyphosis decreases the patients' functional status and quality of life. To correct or prevent further deterioration, different surgical techniques have been introduced. Our aim is to present our clinical experience in kyphectomy and pedicle screw fixation with a posterior-only approach in pediatric patients with myelomeningocele and to discuss the technique with a review of the literature. Materials and Methods: Four patients with lumbar and 2 patients with thoracolumbar kyphosis (female:male ratio = 1:5) secondary to myelomeningocele were operated between January 2009 and October 2012. The median age was 5.5 years (range = 3-10 years). The criteria of the patient selection for the procedure were progression of kyphosis angle, impaired truncal balance and cosmetic deformity. In this retrospective study, we performed chart reviews for demographic and clinical data. We measured the pre- and postoperative kyphosis angles by using the Cobb method on lateral x-rays. Results: The mean preoperative kyphosis angle was 114.3° (range = 91-136°). The mean operative time was 171.7 min (range = 110-220 min). The mean intraoperative blood loss was 450 cc (range = 300-700 cc). The postoperative mean kyphosis angle was 28.2° (range = 13-33°). Five patients had skin breakdown. After osteofusion was established, those 5 patients' instrumentations were explanted. No acute or immediate postoperative complications occurred. Other complications were pneumonia and urinary tract infection. In the long term, 2 patients died due to pneumonia and slit-ventricle syndrome, respectively. Conclusions: Kyphectomy and pedicle screw instrumentation with the posterior-only approach dramatically reduces the kyphosis angle that develops in patients with myelomeningocele. The method itself is less time-consuming and leads to less intraoperative blood loss compared to other methods used for this patient population. Skin breakdown is the most common short-term complication.

ABSTRACThave been held yearly for the past 28 years and are becoming more international every year.In this study, our purpose was to evaluate publication rates of the presentations in the last four years' annual scientific meetings of TNS. █ mATERIAl and mEThODSAbstracts of both podium and poster presentations were retrieved from the congress booklets of TNS.

zamanlama ilk 72 saat içinde primer defektin kapatılmasıdır. Defektin kapatılmasından sonra hastada hidrosefali gelişme olasılığı yüksek olduğu için bu açıdan takipleri yapılarak uygun cerrahi prosedür uygulanır. Bundan sonra hastanın yaşam boyu takibi gerekmektedir [2].

ObjectiveCervical spine encompasses a bridge role between the head and the lower parts of the spine and therefore has unique properties. Our aim in this study was to evaluate the cervical sagittal alignment parameters in pediatric and adult non-surgical patients and to find any differences in respect of age, sex and admission type.MethodsAll patients who were admitted to emergency and neurosurgery clinics of Diyarbakir Bismil State Hospital due to cervical spine problems (trauma, radiculopathy, paraspinal pain) in 2014 were enrolled retrospectively into the study. Cervical anterior-posterior and lateral X-rays were obtained. Our exclusion criteria were cervical coronal deformity, multitrauma, Glasgow Coma Scale <15, traumatic disruption of the cervical spine, history of malignancy, spinal infection, metabolic or rheumatologic diseases.ResultsThere were 44 female and 55 male patients (n=99) in the study. Thirty-five (35.35%) of the patients were younger than 18 years of age. Mean cervical spinal alignment parameters were as follows: -42.81±11.23° (OC2), -17.15±11.48° (C2-C7), -29.82±7.60° (T1 slope), -3.62±3.05° (C3), -3.14±3.05 (C4), -3.80±2.74° (C5), -3.12±2.36° (C6), -3.43±2.53° (C7). Positive correlations were observed between age-C2C7 angle, C2C7 angle-T1 slope, C3 angle-C4 angle, C4 angle-OC2 angle, C4 angle-T1 slope, C4 angle-C5 angle. The one only negative correlation was between OC2 angle-C2C7 angle.ConclusionIn this regional study, it has been observed that global cervical lordosis increases as age increases. C4 vertebra is in the middle of this evaluation as it has many correlations with other cervical segments, which should be kept in mind when making surgical plans for this delicate spine region.
