    (Türk Ortopedi ve Travmatoloji Derneği, 2010) Vural, Recep; Akesen, Burak; Karakayalı, Mehmet; Yalçınkaya, Ülviye; Aydınlı, Ufuk; Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi ve Travmatoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Patoloji Anabilim Dalı.; AAH-9833-2021; AAH-8924-2021; 16318100900; 23102160500; 8630188700; 6508300295; 6602800134
    Objectives: The aim of this study was to compare the effects of autoclaving and pasteurization on bone healing. Methods: Twenty-five full-grown male rabbits were included in the study; all 25 had bone blocks resected and reimplanted. In group 1, bone blocks were autoclaved; in group 2, bone blocks were pasteurized; and in group 3 (controls), resected bone blocks were reimplanted without sterilization. Results: Heiple scores of the proximal parts of the fusion surfaces in group 1, group 2, and group 3 were 12.8 +/- 0.4, 6.8 +/- 1.2, and 10.2 +/- 1.9, respectively. Heiple scores of the distal parts of the fusion surfaces in group I, group 2, and group 3 were 10.8 +/- 0.8, 6.0 +/- 1.1, and 9.8 +/- 1.5, respectively. Differences in radiologic scores were not statistically significant between the groups for proximal or distal fusion surfaces at 3 and 6 weeks. Conclusion: In conclusion, pasteurization has a less negative effect on bone healing than autoclaving, and can be considered for bone sterilization in certain circumstances.

    Iliosacral fixation after type-1 hemipelvectomy: A novel technique
    (Acta Medica Belgica, 2012-06) Şerifoğlu, Rasim; Aydınlı, Ufuk; Akesen, Burak; Yalçınkaya, Ulviye; Hakyemez, Bahattin; Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi ve Travmatoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Patoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; 0000-0001-8729-4715; 0000-0002-8679-6008; 0000-0002-2097-7842; 0000-0002-3425-0740; CEM-8094-2022; AAI-2318-2021; AAH-8924-2021; AAH-9833-2021; 6602800134; 23102160500; 55257709100; 6602527239
    Involvement of the iliac bone and a sacroiliac joint with malignant tumours is not uncommon, treatment is difficult due to the anatomy of the pelvis. Resection of the tumour mass must be extensive in order to achieve safe margins, but this may lead to instability and poor results. We present a new technique for reconstruction after resection of the iliac bone and sacroiliac joint including a sacral ala, and we present two illustrative cases, with 2 years follow-up. Following en bloc resection of a chondrosarcoma in the iliac bone, two or three polyaxial pedicle screws were placed transversly into the sacrum. Two polyaxial pedicle screws were also inserted into the remaining pubic and ischial bone respectively. After completion of the construct with rods, a cortical strut graft from the ipsilateral fibula was placed between the rods. Next a split mesh was placed around the implants and was filled with 60 cc bone chips allografts. Both patients were mobilized with crutches and partial weight bearing for 4 weeks and then fullweight bearing. After two years follow-up, they were ambulatory without external support and their radiological results remained satisfactory. This technique for reconstruction after type I pelvic resection is advantageous in that it saves mobile lumbar segments.

    Long-term outcome after surgical treatment of thoracolumbar fractures versus a control group of healthy volunteers
    (Acta Medica Belgica, 2011-02) Yaray, Osman; Akesen, Burak; Aydınlı, Ufuk; Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi ve Travmatoloji Anabilim Dalı.; AAH-9833-2021; 36538242000; 23102160500; 6602800134
    The authors conducted a retrospective study on the long term outcome (+/-9 years) after instrumentation for thoracolumbar fractures. This study is probably unique in that it compares the surgical group with a control group of healthy volunteers, rather than with a group of conservatively treated Patients. All classical outcome measures were used : ODI, RMDQ, VASSS, VAS, Denis Pain scale, SF-36 Bodily Pain, SF-12 Bodily Pain, the remaining SF-36 and SF-12 scores, and the Denis Work Scale. As expected, the large majority of the scores was better in the healthy group. The difference was significant, except as far as the SF-tests were concerned.
