Article Citation - WoS: 5Depression, Anxiety, and Post-Traumatic Stress Disorder Following Orthopedic War Injuries(Cureus Inc, 2021) Biçen, Ahmet Çağdaş; Akdemir, Mehmet; Gulveren, Dilek; Dirin, Deniz; Ekin, AhmetIntroduction There are ongoing wars worldwide, during which significant numbers of people are injured. Several studies have indicated that high rates of depression and anxiety are seen in war-injured patients. Methods Eighty-one male patients treated between November 2019 and January 2021 far from home in a Turkish hospital due to war injuries that happened in the Libyan Civil War were investigated. Demographic characteristics and injury data of the patients were evaluated regarding age, Injury Severity Score (ISS), location of injuries, type and mechanism of injuries, operations, and accompanying traumas. The psychological statuses of the patients were evaluated with the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and post-traumatic stress disorder (PTSD) records filled out at the first admission to the hospital. Results The mean age of the patients was 29.8 +/- 7.7 (19-56) years. While 59 patients had fractures, 22 patients had only soft tissue injuries. Eighteen patients suffered from other accompanying injuries. While 85.2% of the patients showed symptoms of depression, 82.7% of the patients suffered from anxiety and PTSD symptoms were seen in 86.4% of the patients. Statistical analysis was performed to investigate the effects of injury severity, duration of hospitalization, number of operations, and age on depression, anxiety, and PTSD among these patients with war injuries. The results did not indicate any significant effect of injury severity, hospitalization duration, or operations. Conclusion Depression, anxiety, and PTSD are common in patients injured in wars. Injury severity does not seem to affect depression, anxiety, or PTSD in these patients.Conference Object Citation - WoS: 1Citation - Scopus: 15Blockchain Applications in Healthcare(Institute of Electrical and Electronics Engineers Inc., 2018) Ekin A.; Unay D.In this paper, we present the applications of blockchain technology in healthcare.

This study hypothesizes that arthroplasty is not superior to conservative treatment in the management of multi-part proximal humerus fractures in elderly patients. Material and Method: Patients aged 65 and above with 3–4-part proximal humerus fractures, treated either conservatively or with arthroplasty, were included in the study. The minimum follow-up period was set at 12 months. Functional evaluations of the patients were performed using the Quick Disabilities of Arm, Shoulder and Hand (Q-DASH) scoring system. Statistical analysis comparing the two groups was conducted using the SPSS software. The mean values of numerical data were analyzed using the Mann-Whitney U test, while categorical data were compared using the Chi-square test. A significant level of 0.05 was considered. Results: A total of 67 patients who received adequate clinical follow-up were included in the study (50 conservative 17 arthroplasty). The average age of the patients was 76.12 years, with 9 male and 58 female patients. The average follow-up period was 22.61 months (range: 12-82). There were no statistically significant differences in age, gender, side, follow-up period, and fracture type distribution between the two groups. However, a significant difference in Q-DASH scores was observed (p<0.05). Conclusion: In the treatment of proximal humerus fractures, even when they are multi-part fractures, conservative treatment should may be the first choice. We think that the early results of conservative treatment are better than arthroplasty.Article Citation - WoS: 2Comparison of Expandable and Locked Intramedullary Nailing for Humeral Shaft Fractures(Cureus Inc, 2021) Akdemir, Mehmet; Biçen, Ahmet Çağdaş; Ozkan, Mustafa; Ekin, AhmetIntroduction In this study, we clinically and radiologically investigated whether the application of expandable nails for surgical treatment of humeral shaft fractures has an advantage over locked intramedullary nails. Methods Patients treated with intramedullary fixation due to humeral shaft fractures in our clinic were investigated retrospectively. Patients with fractures of type 12A and 12B according to the AO classification in the middle 1/3 shaft region of the humerus were divided into two groups as those receiving fixation with expandable nails and with locked intramedullary nails. The union rate, union time, Q-DASH scores, duration of surgery, and complication rates were statistically compared between the two groups. Results The study included 38 patients with clinical follow-up from among 47 patients; 20 patients received fixation with locked intramedullary nails and 18 with expandable nails. The mean age of the patients was 56.92 (1991) years and 53% (n=20) were men while 47% (n=18) were women. During statistical evaluation, a statistically significant difference was found between the groups for union (100% and 72.2%) and complication rates (6% and 13%). More union and lower complication rates were found in patients treated with locked intramedullary nails. In comparing the mean of surgical times (71.1 and 30.2 min), expandable nails had a shorter surgical time. However, there was no statistically significant difference between the union time and Q-DASH scores between the two groups. Conclusion Locked intramedullary nails are a better fixation method than expandable nails due to the low complication rate and high rate of union. However, due to shorter surgery time, expandable nailing is an alternative method in limited cases.Article Citation - WoS: 14Citation - Scopus: 12Analysis of Risk Factors Affecting Mortality in Elderly Patients Operated on for Hip Fractures: a Retrospective Comparative Study(Turkish Assoc Orthopaedics Traumatology, 2021) Biçen, Ahmet Çağdaş; Akdemir, Mehmet; Turken, Mehmet Aykut; Cekok, Kubra; Ekin, Ahmet; Turan, Ahmet CemilObjective: The aims of this study were (1) to investigate the effects of different demographic and perioperative modalities on mortality rates and (2) to compare mortality rates between different implants in elderly patients operated on for hip fractures. Methods: In this retrospective study, a total of 314 patients who were operated on for hip fractures were included study. Patients were then divided into four groups based in their implant types: long-stem cementless bipolar hemiarthroplasty (n = 124; 102 female, 22 male; mean age = 84.2 +/- 6.4 years), standard-stem cementless bipolar hemiarthroplasty (n = 74; 48 female, 26 male; mean age = 83.5 +/- 6.9 years), antegrade intertrochanteric nail (n = 61; 35 female, 26 male; mean age = 78.5 +/- 6.8 years), and total hip arthroplasty (n = 55; 34 female, 21 male; mean age = 72.5 +/- 4.3 years). Data including gender, age, duration from injury to surgery, American Society of Anesthesiologists (ASA) score, comorbidities, use of antiplatelet agents, Barthel Index of Activities of Daily Living, type of anesthesia, operation time, preoperative hemoglobin values, blood transfusions given, duration of hospital stay, complications, and type of fracture were recorded. Results: Overall, the mean follow-up was 36.5 (range = 0 - 107) months. The overall mortality rate was 53.2%. The median survival duration was 44.2 +/- 5 months (range = 34.3 - 54). Survival rates were found significantly different among the groups (P = 0.001). In the first three years postoperatively, the mortality rate was higher in the standard-stem bipolar hemiarthroplasty group, but in the long-term follow-up, the long-stem bipolar hemiarthroplasty group exhibited the higher mortality rates. It was observed that some parameters had statistically significant effects on the mortality rates. Male gender, higher age, lower hemoglobin values, increased number of blood transfusions, ASA scores >= 3, the existence of >= 3 comorbidities were found as main predictors of increased mortality rates. Conclusion: The results of this study have shown that age, gender, preoperative hemoglobin levels, ASA scores, and comorbidities are significant factors affecting mortality in elderly patients operated on for hip fractures. Long-stem cementless bipolar hemiarthroplasty appears to show similar rates of mortality with standard-stem cementless bipolar hemiarthroplasty.Article Efficacy of Preoperative Mri in Detecting Biceps Tendon Pathologies in Rotator Cuff Tears: Correlation of Mri and Intraoperative Findings(2022) Biçen, Ahmet Çağdaş; Ünal, Abdullah Meriç; Ekin, Ahmet; Özkan, MustafaObjective The aim of this study is to evaluate the accuracy of magnetic resonance imaging (MRI) in detecting biceps lesions in patients with rotator cuff tears. Material and Methods A total of 168 patients operated on between January 2012 and February 2020 were included in the study. All the patients underwent arthroscopic surgery with the diagnosis of rotator cuff tears. All patients were operated on under general anesthesia and in the beach chair position. Demographic data and preoperative MRI findings were recorded. Arthroscopic findings were accepted as the standard reference and correlated with preoperative MRI records. Results In preoperative images, full-thickness rotator cuff tears were identified in 118 (70.2%) cases and partialthickness tears in 50 (29.8%) cases. Labrum/SLAP lesions were detected in 18 (10.7%) cases. Biceps disorders were reported in 51 (30.4%) cases. During the surgeries, we observed additional pathologies in 41 (24.4%) cases besides the preoperatively detected lesions. Rotator cuff and labrum/SLAP repairs were performed in the same surgical sessions. The majority of newly detected lesions were biceps lesions, being identified in 26 (15.5%) cases. In 41 (24.2%) cases tenodesis, tenolysis, or tenotomy were performed for biceps lesions. LHBT surgery was performed in 26 cases with negative MRI. Biceps lesions were confirmed in 77 (45.8%) cases intraoperatively; therefore, the accuracy of MRI in detecting these lesions was 66.2%. Conclusion Biceps lesions are among the common pathologies of the shoulder. Preoperative MRI is important in evaluation of the shoulder, but the efficacy of MRI may be limited in detecting biceps disorders. Arthroscopic surgery is crucial in diagnosis and treatment of LHBT lesions.
