Item The Retrospective Analysis of the Effect of Balloon Kyphoplasty to the Adjacent-segment Fracture in 171 Patients(2014) Civelek, Erdinc; Cansever, Tufan; Yilmaz, Cem; Kabatas, Serdar; Gulsen, Salih; Aydemir, Fatih; Altnors, Nur; Caner, Hakan; https://orcid.org/0000-0002-3988-4064; https://orcid.org/0000-0002-2353-8044; https://orcid.org/0000-0003-2691-6861; https://orcid.org/0000-0002-7535-1804; https://orcid.org/0000-0002-3400-9025; 24795949; ABI-6105-2020; AAK-2948-2021; AAA-3069-2020; AAJ-5746-2021Study Design: Analysis of the adjacent-segment fractures in 171 balloon kyphoplasty (BK)-performed patients. Objective: The purpose of this study was to investigate the risk factors for new symptomatic vertebral compression fractures (VCF) after BK. Summary of Background Data: Although there are many studies about the incidence and possible risk factors for occurrence of adjacent-level fractures, there is no consensus on the increased risk of adjacent-level fractures after BK. Methods: We performed a retrospective analysis of 171 patients treated with percutaneous kyphoplasty. The follow-up period was 41.04 +/- 21.78 months. The occurrence of new symptomatic VCF was recorded after the procedure. We evaluated the variables of patient age and sex, the amount of injected cement, the initial kyphotic angle (KA) of VCF, the change of the KA after BK, the severity of osteoporosis, and the percentage of height restoration of the vertebral body. Furthermore, possible risk factors were reported for new symptomatic VCFs. Results: The only 2 factors identified as being significantly associated with adjacent-level fractures were the sex (P=0.001) of the patient and the preoperative KA (P=0.013). The patients with new symptomatic compression fracture had higher initial KA than those without fractures. The female group had higher risk than the male group in occurrence of the new vertebra fractures. The severity of the osteoporosis (low bone mineral density) was not a determinant in occurrence of the new VCF after BK. Conclusions: If the patients experience severe or mild back pain with higher preoperative KA, especially in the first 2 months, then they deserve detailed radiologic examination. To avoid subsequent fracture in the same or adjacent level, vertebral body should be filled adequately and sagittal balance should be obtained with KA correction. BK alone did not influence the incidence of subsequent VCF.Item Tibia Stress Fracture Secondary to Obsessive Compulsive Disorder(2016) Guler, Gulen; Kutuk, Meryem; Yildirim, Veli; Celik, Gonca Gul; Toros, Fevziye; Milcan, Abtullah; https://orcid.org/0000-0002-2918-7871; 27284118; AAI-9626-2021Obsessive compulsive disorder (OCD) is a chronic psychiatric disorder characterized by obsessions and compulsions. Early-onset OCD is one of the most common mental illnesses of children and adolescents, with a prevalence of 1% to 3%. It is related to worse lifespan symptoms and prognosis. Therefore, the treatment of OCD in children and adolescent has gained importance. If it is not treated successfully, the compulsive behaviors may cause extreme stress for children and their parents. Although minor complications of OCD are commonly observed, major complications are considerably rare due to the nature of compulsive behaviors. Apparently, loss of vision, autocastration, rectal prolapse are examples of major complications secondary to OCD. As far as we know, it is the first case of tibia stress fracture secondary to OCD. In the present case report, we will discuss tibia stress fracture developing secondary to compulsive behavior due to OCD.Item Does an infra pectineal plate alone provide adequate fixation in anterior column posterior hemitransverse acetabular fractures? A comparative biomechanical study(2022) Simsek, Ekin Kaya; Haberal, Bahtiyar; Mahmuti, Ates; Balcik, Bedi Cenk; Demirors, Huseyin; 0000-0002-1668-6997; 35920432; W-9080-2019BACKGROUND: The purpose of this study is to compare biomechanical properties of suprapectineal (SP) plate fixation, infrapectineal (IP) plate fixation, and both SP and IP plate fixation in anterior column posterior hemitransverse (ACPHT) fractures of the acetabulum using posterior and anterior column screws. METHODS: In 21 hard plastic left hemipelvis models, ACPHT fractures of the acetabulum were created, and in three different fixation groups, the methods were compared: Group 1: SP plating using a 3.5 mm reconstruction plate and cortical screw fixation, Group 2: Infrapectineal plating using 3.5 mm reconstruction plate and cortical screws combined with posterior and anterior column screws, and Group 3: Combined fixation with SP and IP plating using 3.5 mm reconstruction plates and cortical screws. Maximum load to failure (strength) of these three groups was compared between groups. RESULTS: The mean maximum load of failure for three groups was 2921 N, 2018 N, and 3658 N, respectively. When strength was compared considering the force that causing implant failure, it was determined that the strongest fixation was achieved when SP and IP fixation method were applied together, followed by SP only fixation and IP fixation supported by anterior and posterior column screws, respectively. CONCLUSIONS: The combined application of SP and IP fixation provides the most stable fixation of the ACPHT acetabular fractures, and IP fixation does not provide comparable biomechanical stability despite reinforcement with three-column screws placed away from the plate. Although IP fixation supported by anterior and posterior column screws with the limited combined approach is less invasive approach for patients, SP fixation should be included in the surgical treatment method to ensure adequate stability.
