Efficacy of Single Titanium Elastic Nail in the Treatment of Child Femur Fractures
Background: Femoral shaft fractures in childhood constitute an important part of emergency visits to orthopedic clinics. The aim of this study was to investigate the efficacy and reliability of a method in the treatment of simple fractures in the middle of the femoral diaphysis in patients with multiple injuries or in the treatment of cases with a medullary canal that is too narrow for two nails, with a single stretch nail thicker than half the diameter of the canal. Methods: Between July 2002 and November 2006, examinations were made of 11 femoral fractures in 11 patients who were admitted to the pediatric emergency department of Tepecik Training and Research Hospital with a diagnosis of femoral fracture and who were hospitalized and treated with a single flexible intramedullary titanium nail. Results: In the follow-up, no problem was found in terms of union and length difference in any of the cases, except for a 10º varus deformity present after surgery in one case. Conclusions: Elastic intramedullary nailing is an effective method in the treatment of simple femoral fractures in children. A single elastic nail provides adequate stability following open reduction with minimal incision in patients whose short operating time must be kept short such as those with head trauma, thoracic trauma, or intra-abdominal pathology, or patients with a narrow medullary canal where two flexible nails cannot pass. We think that it is a feasible method because it causes minimal soft tissue damage.

Comparison of below‐knee and above‐knee amputations with demographic, comorbidity, and haematological parameters in patients who died
Background: This study aimed to establish mortality predictive parameters with a higher contribution to mortality by comparing the demographic data, comorbid factors, and haematological values of patients who underwent below‐knee and above‐knee amputation and had died during the follow‐up period.Materials and methods: Between March 2014 and January 2022, 122 patients in a single centre who developed foot gangrene due to chronic diabetes and underwent below‐knee or above‐knee amputation were evaluated retrospectively. Patients who died of natural causes during the post‐operative period were included in the study. Those who were amputated below the knee were assigned to Group 1, and those who were amputated above the knee were assigned to Group 2. The patients' age, gender, side of amputation, comorbid diseases, American Society of Anaesthesiologists (ASA) score, Charlson comorbidity index (CCI), death time, and haematological values at the time of first admission were compared between the two groups and statistical analyses were performed.Results: Group 1 (n = 50) and Group 2 (n = 37) had similar distributions in terms of age, gender, side of operation, number of comorbidities, and CCI (p > 0.05). Group 2's mean ASA score and c‐reactive protein (CRP) levels were statistically higher than those of Group 1 (p < 0.05). Death time, albumin value, and HbA1c levels were statistically lower in Group 2 than in Group 1 (p < 0.05). There were no significant differences between the groups in haemogram, white blood cells (WBC), lymphocytes, neutrophils, creatinine, and Na values at the time of first admission (p > 0.05).Conclusion: A high ASA score, low albumin value, and high CRP value were significant predictors of high mortality. Creatinine levels and HbA1c values were quite ineffective in predicting mortality.Level of evidence: Level 3, retrospective comparative study.

Analysis of Factors Affecting the Third- and Twelfth-Month Mortality in Patients with Hip Fractures Aged 80 Years and Older
Background The purpose of this study was to evaluate the possible risk factors that are related with mortality at third and twelfth months after hip fractures in a large population of patients aged 80 years and older. Methods 605 patients were evaluated in terms of the localization of the fracture, gender, age, side of the fracture, the type of applied procedure, anesthesia type, hospitalization time, time to operation, comorbidities, ASA score, the values of preoperative hemoglobin, lymphocyte and neutrophil percentage, white blood cell, albumin, sodium levels. The state mortality system was used to investigate whether patients are alive or died. Statistical analysis was performed to evaluate the important factors on third- and twelfth-month mortality. Results Male gender, neurologic–cardiac–chronic obstructive pulmonary (COP) diseases, preoperative hemoglobin level < 10 g/dL, arthroplasty and external fixator groups, ASA grade ≥ 3, delaying the surgery more than 4 days, longer hospitalization time, lower albumin levels and advanced age were found to be statistically significant factors for 3-month mortality (p values were; 0.01, 0.02, 0.01, 0.01, 0.047, 0.01, 0.02, 0.002, < 0.001, 0.002 and 0.01, respectively). Male gender, hypertension–neurologic–cardiac diseases, preoperative hemoglobin level < 10 g/dL, delaying the surgery more than 4 days, longer hospitalization time, lower lymphocyte percentage, lower albumin levels and advanced age were found to be statistically significant factors for 12-month mortality (p values were; < 0.001, 0.01, 0.01, 0.01, 0.03, 0.01, < 0.001, 0.01, 0.004 and < 0.001, respectively). Conclusion COP, advanced age, and heart disease were the most important factors in 3-month mortality. Long hospitalization time, male gender and advanced age were the most important factors affecting the 12-month mortality. Level of Evidence Prognostic level IV.

Acute kidney injury after hip fracture surgery in patients over 80 years of age
Background The aim of the study is to determine the rate of acute kidney injury (AKI) after hip fracture surgery over the age of 80 and to investigate the factors associated with AKI. Methods From January 2015 to January 2020, 589 patients who underwent surgery of hip fractures at our institution were retrospectively reviewed. Serum creatinine (sCr) was analysed daily pre- and postoperatively during the hospital stay. Patients were divided into groups; AKI and non-AKI based on KDIGO (Kidney Disease Global Outcomes) criteria. The incidence, risk factors, and mortality of postoperative AKI were investigated. Results Out of 589 patients, 58 developed an AKI (9.8%). Smoking (p: 0.004), pre and postoperative low albumin level (p < 0.05), pre- and postoperative high potassium level (p < 0.05), pre- and postoperative high urea levels (p < 0.05), high amount of intra-operative bleeding (p: 0.003) and prolonged surgery time (p: 0.003) were found to be risk factors associated with AKI. Although the mortality rate was higher in the AKI group, it was not statistically significant (p > 0.05). Conclusion AKI is a temporary but common complication following hip fracture surgery, which can also be predicted if risk factors are adequately observed. It typically increases the length of hospital stays, mortality and morbidity. Level of evidence Level III evidence, Retrospective comparative study

Epidemiologic Study of Syrian Refugees Underwent Surgery Due to Fracture in a Tertiary Reference Hospital in Turkey
This study aims to analyze the spectrum, management, and outcome of Syrian refugees’ fracture over four-year period, highlighting challenges in management and follow-up. This was a retrospective review of Syrian refugee patients operated for fractures at our centre from January 2015 to January 2019. The patients were evaluated for age, gender, mechanism of injury, location and type of fracture, presence of accompanying injuries, surgical technique, complications, mortality and morbidity. The comparison of complications and postop outpatient clinic controls between Turkish citizens and Syrian refugees were also evaluated. The study included a total of 455 patients comprising 281 adults (202 males, 79 females) with a mean (SD) age of 41.1 (19.3) years and 174 children with a mean age of 8.8 (4.9) years. The trauma mechanism was most commonly fall in both adult and pediatric patients (86.6% / 73.5%). Whilst lower limb fractures were more common in adults (73.7%), upper limb fractures were more common in children (63.4%). The presence of accompanying trauma was determined in 21 (7.5%) adults and 10 (5.7%) children. Multiple fractures were determined in 12 (4.3%) adults and eight (4.6%) children. Plate fixation (PF) was most used in 137 (48.8%) adult patients and K-wire augmentation was used in 75 (43.1%) pediatric patients. Out of the 455 patients, 41 (14.6%) adults and 13 (7.3%) children developed complications. Whilst three adult patients were died during follow-up, no deaths were recorded in the pediatric patients. Complication rate was 54/455 in Syrian refugees and 32/455 in citizens. It was observed that the complication was significantly higher in immigrants (p: 0.017). Sixty-five (14.2%) Syrian immigrants did not come to the outpatient clinic control at all or once, while this rate was 29/455 (6.3%) for Turkish citizens (p = 0.012). Inadequate living conditions and lack of communication faced by refugees reduce the rate of patient follow-up and negatively affect the results of orthopedic trauma.
