    (KOREAN SOC SPINE SURGERY, 2018-01-01) Akgul, Turgut; Sariyilmaz, Kerim; Korkmaz, Murat; Ozkunt, Okan; Kaya, Ozcan; Dikici, Fatih
    Study Design: trospective analysis of adolescent idiopathic scoliosis. Purposep: s study aimed to investigate the influence of distinct distal fusion levels on spinopelvic parameters in patients with adolescent idiopathic scoliosis (AIS) who underwent posterior instrumentation and fusion surgery. Overview of Literature: e distal fusion level selection in treatment of AIS is the one of milestone to effect on surgical outcome. Most of the paper focused on the coronal deformity correction and balance. The literature have lack of knowledge about spinopelvic changing after surgical treatment and the relation with distal fusion level. We evaluate the spinopelvic and pelvic parameter alteration after fusion surgery in treatment of AIS. Methods: total of 100 patients with AIS (88 females and 12 males) were retrospectively reviewed. Patients were assigned into the following three groups according to the distal fusion level: lumbar 2 (L2), lumbar 3 (L3), and lumbar 4 (L4). Using a lateral plane radiograph of the whole spine, spinopelvic angular parameters such as thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT) were radiologically assessed. Results: e mean age was 15+/-2.4 years, and the mean follow-up period was 24.27+/-11.69 months. Regarding the lowest instrumented vertebra, patients were categorized as follows: 30 patients in L2 (group 1), 40 patients in L3 (group 2), and 30 patients in L4 (group 3). TK decreased from 36.60+/-13.30 degrees preoperatively to 26.00+/-7.3 degrees postoperatively in each group (p=0.001). LL decreased from 52.8+/-9.4 degrees preoperatively to 44.30+/-7.50 degrees postoperatively (p=0.001). Although PI showed no difference preoperatively among the groups, it was statistically higher postoperatively in group 3 than in the other groups (p<0.05). In addition, in group 2, PI decreased from 50.60+/-8.74 degrees preoperatively to 48.00+/-6.84 degrees postoperatively (p=0.027). SS decreased from 35.20+/-6.40 degrees preoperatively to 33.40+/-5.80 degrees postoperatively (p=0.08, p>0.05). However, mean SS was significantly higher in group 3 (p=0.042, p<0.05). PT decreased from 15.50+/-7.90 degrees preoperatively to 15.2+/-7.10 degrees postoperatively. The positive relationship (28.5\%) between LL and PI measurements was statistically significant (r=0.285

    Selection of distal fusion level in terms of distal junctional kyphosis in Scheuermann kyphosis. A comparison of 3 methods
    (TURKISH ASSOC ORTHOPAEDICS TRAUMATOLOGY, 2018-01-01) Dikici, Fatih; Akgul, Turgut; Sariyilmaz, Kerim; Korkmaz, Murat; Ozkunt, Okan; Sar, Cuneyt; Domanic, Unsal
    Objective: The aim of this study was to investigate the effect of distal fusion level selection on the distal junctional kyphosis (DJK) in Scheuermann kyphosis (SK) patients who underwent posterior fusion. Methods: Thirty-nine SK patients who underwent posterior fusion with a minimum follow-up of 3 years were retrospectively evaluated. According to the distal fusion level, patients were divided into 3 groups. Group S

    Autologous segmental tibia bone transfer in the treatment of distal tibia Gustilo-Anderson type-III open fracture: A case report
    (ELSEVIER SCI LTD, 2016-01-01) Demirel, Mehmet; Akgul, Turgut; Polat, Gokhan; Cakmak, Mehmet Fevzi; Dikici, Fatih
    INTRODUCTION: We present the results of a two-stage reconstruction performed with autologous segmental tibia bone transfer on a distal tibia Gustilo-Anderson type-IIIC open fracture in this paper. Our aim is to discuss the results of this surgery, potential failures and complications in our procedures, and ways to protect against osteolysis. PRESENTATION OF CASE: A 20-year-old male who has undergone surgery in our clinic for a Gustilo-Anderson type-III open fracture of the left tibia using autologous tibia segmental bone transfer. The first operation consisted of removing the exposed bony fragment and placing it in the abdominal wall. Fifty days after the first operation, an intramedullary nailing operation was performed using the autologous bone fragment kept in the abdominal wall. Before the final procedure, we assessed the viability of the bone fragment using scintigraphy as well as the paprika sign was observed on the fragment during operation. Patient was seen in follow-up every three weeks to evaluate for successful osteosynthesis

    Surgical Approach Algorithm in the Treatment of Lumbar and Thoracolumbar Pyogenic Spondylodiscitis
    (TURKISH NEUROSURGICAL SOC, 2022-01-01) Akgul, Turgut; Bayram, Serkan; Korkmaz, Murat; Karalar, Sahin; Dikici, Fatih; Sar, Cuneyt
    AIM: To reveal the efficiency of our surgical approach algorithm in patients with thoracolumbar pyogenic spondylodiscitis based on the involvement of anatomical structure. MATERIAL and METHODS: Data of patients who underwent debridement or stabilization surgery for thoracolumbar pyogenic spondylodiscitis from January 2012 to December 2018 were reviewed. Lumbar and thoracolumbar spondylodiscitis was classified into four stages based on anatomical involvement. Infection was limited in the disc space, which had not spread to the endplate in stage 1 and progressed as two-level corpus involvement of >1/2 of vertebral corpus bony destruction or as failed treatment in stage 4. Neurological function was evaluated using Frankel's grading postoperatively. Functional outcomes were categorized according to the Kirkaldy-Willis criteria. RESULTS: The study included 39 patients, with a mean age of 58.2 years. Of these patients, 10, 12, 13, and 4 had stages 1, 2, 3, and 4 spondylodiscitis, respectively. The mean follow-up period was 60.2 (12-184) months. All patients with stages 1 and 2 spondylodiscitis had grade E injury

    Posterior Approach Alone Versus Combined Anterior and Posterior Approach in the Management of Vertebral Tuberculosis
    (TURKISH NEUROSURGICAL SOC, 2019-01-01) Demirel, Mehmet; Akgul, Turgut; Pehlivanoglu, Tuna; Karademir, Gokhan; Bayram, Serkan; Dikici, Fatih; Sar, Cuneyt
    AIM: To compare posterior surgery alone versus combined anterior and posterior surgery for the management of spinal tuberculosis. MATERIAL and METHODS: Data from 31 consecutive patients who underwent surgery for spinal tuberculosis were analyzed retrospectively. Patients were divided into two groups as group A (posterior surgery alone) or group B (combined anterior and posterior surgery), and groups were compared in terms of invasiveness of the procedure, spinal deformity, fusion, neurological status, and postoperative complications. RESULTS: Group A included 16 patients (mean age: 56 years, range: 29-75) with a mean follow-up period of 29 months (range 12-60) while group B included 15 patients (mean age: 60 years, range: 35-73) with a mean follow-up period of 28 months (range 12-60). Procedurally, average operation time and mean length of hospitalization were shorter, and mean blood loss was lower in group A (p<0.05) compared to group B. Postoperative bone fusion took significantly (p<0.05) longer time in group A (10.5 +/- 2.1 months)than in group B (9.3 +/- 3.1 months), and all patients with a neurological deficit recovered completely during the postoperative period. No significant differences were observed between two groups with respect to postoperative complications (p>0.05). CONCLUSION: Combined anterior-posterior surgery may not be required for treating vertebral tuberculosis as posterior surgery alone appears to be sufficient.
