Öğe Comparable outcomes of arthroscopic and mini-open tightrope fixation for acute acromioclavicular joint dislocations(Bmc, 2025) Ulusoy, Ibrahim; Guzel, IsmailBackground Acute high-grade acromioclavicular (AC) joint dislocations are commonly treated surgically, with multiple fixation options available. Arthroscopic TightRope (AT) and mini-open TightRope (MOT) techniques are widely used, but comparative evidence remains limited. Methods In this retrospective comparative study, 96 patients with Rockwood type III-V AC joint dislocations were treated between 2018 and 2023 using either AT (n = 52) or MOT (n = 44). Two patients lost to follow-up were excluded. Primary outcomes included Constant-Murley and UCLA scores, while secondary outcomes were visual analog scale (VAS) pain scores, coracoclavicular (CC) distance on radiographs, operative time, and complications. The sample size/power calculation was corrected (two-group comparison, alpha = 0.05, achieved power similar to 90% with d approximate to 0.67). A sensitivity analysis restricted to Rockwood IV-V was additionally performed to test robustness. Results At one year, both groups showed significant improvements in Constant-Murley and UCLA scores (p < 0.001 within groups) with no between-group differences (p > 0.05). The mean difference in operative time between the groups was 14.3 min (95% CI 11.5-17.1, p < 0.001). CC distance difference between groups was 0.2 mm (95% CI - 0.3 to 0.7, p = 0.41), indicating similar radiological stability. Complication rates were low and comparable. The IV-V-only sensitivity analysis yielded results consistent with the overall cohort. Conclusion AT and MOT provide comparable one-year functional outcomes, pain relief, and radiological stability in acute AC dislocations. Differences were limited to perioperative parameters (longer operative time with arthroscopy). Choice of technique should be individualized based on patient factors and surgeon expertise.Öğe Comparison of antirotation proximal femoral nail and talon locking nail systems in the treatment of intertrochanteric fractures: functional and cost-effectiveness outcomes(Springer, 2025) Guzel, Ismail; Ulusoy, Ibrahim; Tantekin, Mehmet Firat; Yilmaz, Mehmet; Kivrak, AybarsPurpose This study aimed to compare the clinical outcomes and cost-effectiveness of two widely used intramedullary fixation systems-the Proximal Femoral Nail Antirotation (PFNA) and the Proximal Femoral Nail with Talon Locking System (PFN-TLS)-in the treatment of intertrochanteric femur fractures (ITFF). MethodsA retrospective cohort study was conducted on 118 patients aged 65-90 years who underwent surgical treatment for ITFF using either PFNA (n = 53) or PFN-TLS (n = 65). All patients were followed for a minimum of 24 months. Preoperative functional evaluation was unavailable; outcomes were assessed at 24 months postoperatively. Surgical parameters, complication and revision rates, functional outcomes (Harris Hip Score [HHS], Visual Analog Scale [VAS], and SF-36), and health-economic indicators (Quality-Adjusted Life Years [QALY], Incremental Cost-Effectiveness Ratio [ICER]) were evaluated. Binary logistic regression analysis was performed to determine independent predictors of favorable functional outcomes. Results The PFN-TLS group demonstrated significantly shorter surgical duration, reduced incision length, and lower fluoroscopy exposure (p < 0.05). At the 24-month follow-up, HHS was significantly higher in the PFN-TLS group (82.7 +/- 7.4) compared to the PFNA group (76.4 +/- 8.1; p = 0.001). VAS and SF-36 scores were also higher, although not statistically significant. Revision rates showed a non-significant trend favoring PFN-TLS. QALY gains were slightly higher in the PFN-TLS group (0.530 vs. 0.449), with a lower cost per QALY ($1,637.93 vs. $1,863.22). PFN-TLS use was independently associated with favorable functional outcomes (OR: 2.62; 95% CI 1.23-5.58; p = 0.013). Conclusion Both PFNA and PFN-TLS are effective options for the management of ITFF. However, PFN-TLS may offer additional clinical and economic benefits, including improved functional outcomes and greater cost-efficiency. Findings should be interpreted with caution due to the retrospective design. Prospective, randomized studies are needed to validate these results and guide implant selection in clinical practice.Öğe Comparison of Intravenous, Topical, and Control Groups in Blood Management During Total Hip Arthroplasty: A Retrospective Analysis(Wiley, 2026) Guzel, Ismail; Ulusoy, Ibrahim; Yilmaz, Mehmet; Tantekin, Mehmet Firat; Kivrak, AybarsObjective Total hip arthroplasty (THA) is a widely performed surgical intervention for managing severe hip pathologies. However, this procedure is often associated with substantial blood loss and an increased need for blood transfusion. Tranexamic acid (TXA), a synthetic antifibrinolytic agent, is frequently administered to mitigate perioperative bleeding. Despite its widespread use, the comparative efficacy and safety of intravenous (IV) and topical TXA administration remain subjects of ongoing debate in the literature. Materials and Methods This retrospective, single-center study evaluated 45 patients who underwent primary THA between 2020 and 2024. The patients were divided into three groups based on TXA administration: IV TXA (n = 15), topical TXA (n = 15), and a control group without TXA (n = 15). Outcomes assessed included perioperative blood loss, transfusion requirements, postoperative hemoglobin decrease, and thromboembolic complications. Group comparisons were further adjusted for baseline confounders using analysis of covariance and multivariable logistic regression. Statistical significance was set at p < 0.05. Results Both IV and topical TXA administration significantly reduced perioperative blood loss compared with the control group. Transfusion rates were numerically lower in the TXA groups, although these differences did not reach statistical significance after adjustment. Mean blood loss was recorded as 820 mL in the IV TXA group, 840 mL in the topical TXA group, and 1100 mL in the control group. No significant difference was found between the IV and topical TXA groups, while both were superior to the control group in terms of hemoglobin decline. Thromboembolic complications and surgical site infection rates were comparable across all groups. Discussion The findings of this study demonstrate that both IV and topical TXA administration provide effective and safe control of perioperative bleeding in THA. The low incidence of thromboembolic events supports the safe use of TXA in clinical practice. Selection of the TXA administration route can be tailored based on patient-specific clinical conditions and the surgeon's preference. Conclusion In conclusion, the appropriate use of TXA during THA effectively reduces the need for blood transfusion and contributes to improved surgical outcomes. These results highlight the value of TXA as a reliable hemostatic agent in modern orthopedic surgery.Öğe Early Versus Delayed Plate Fixation in Pilon Fractures-Which Is More Advantageous?(Mdpi, 2026) Guzel, Ismail; Ulusoy, Ibrahim; Yilmaz, Mehmet; Tantekin, Mehmet Firat; Kivrak, AybarsBackground: Pilon fractures refer to distal tibial fractures that may involve extra-articular, partial articular, or complete intra-articular components, most commonly caused by high-energy trauma. The choice between early (<72 h) and delayed (>7 days) surgical fixation significantly impacts clinical outcomes. This study aimed to compare the effects of early vs. delayed plate fixation on fracture healing time, functional outcomes, and complication rates. Materials and Methods: This retrospective study analyzed 80 patients who underwent surgical treatment for pilon fractures between 2018 and 2023. Patients were divided into two groups: early surgery (<72 h, n = 40) and delayed surgery (>7 days, n = 40). Additionally, patients were categorized based on the fixation method: single-plate fixation (n = 40) and double-plate fixation (n = 40). Outcome measures included fracture healing time (weeks), defined as cortical continuity on radiographs; functional outcomes (AOFAS score); and complication rates (infection, malunion, and implant failure). Results: Shorter healing time was observed in the early surgery group (14.2 vs. 16.8 weeks, p < 0.05). Better functional outcomes were recorded in the early surgery group (AOFAS score: 82.3 +/- 6.5 vs. 78.1 +/- 7.2, p < 0.05). Lower infection rates were noted in the delayed surgery group (7.5% vs. 12.5%, p < 0.05). Double-plate fixation provided better mechanical stability but resulted in higher soft tissue complication rates. Single-plate fixation preserved soft tissue integrity but had higher malunion and implant failure rates. Conclusions: Early surgery is associated with shorter healing time and better functional outcomes, but increased soft tissue complications require careful management. Delayed surgery offers a safer approach for soft tissue healing but may prolong functional recovery. While double-plate fixation ensures greater stability, it may increase soft tissue morbidity, whereas single-plate fixation reduces soft tissue complications but may compromise stability. A personalized surgical approach is recommended for optimal outcomes in pilon fracture management.Öğe Open fractures associated with earthquakes and highenergy trauma: Clinical outcomes and management strategies(Turkish Assoc Trauma Emergency Surgery, 2025) Guzel, Ismail; Ari, Bunyamin; Altunkilic, Tarik; Ulusoy, Ibrahim; Boz, MehmetBACKGROUND: This study aimed to evaluate the epidemiological characteristics, infection rates, complication risks, and clinical management strategies of open fractures resulting from high-energy traumas. Special attention was given to the effects of the 2023 major earthquake on the incidence of open fractures and patient management, comparing different trauma mechanisms retrospectively. METHODS: This retrospective study included 512 patients admitted to a tertiary trauma center between 2019 and 2024. Patients were classified according to five different trauma mechanisms: traffic accidents, falls from height, occupational injuries, gunshot wounds, and earthquake-related traumas. Open fractures were assessed and classified using the Gustilo-Anderson classification to determine the severity of the injuries. Treatment protocols included early antibiotic administration, surgical debridement, wound management protocols, and surgical fixation methods. Statistical analyses were performed to compare differences between early surgical intervention (within 24 hours) and delayed surgical intervention (after 24 hours). Statistical tests used included T-test, Mann-Whitney U test, Chi-square test, and logistic regression analysis. A p-value of <0.05 was considered statistically significant. RESULTS: The mean age of the 512 patients was 37.4 +/- 12.6 years, with 68% males and 32% females. The most common trauma mechanism was traffic accidents (54.2%), followed by falls from height (27.8%), occupational injuries (12.5%), gunshot wounds (5.5%), and earthquake-related traumas (11.3%). A significant proportion of earthquake-related injuries were classified as Gustilo-Anderson Type III fractures (42.8%), which was notably higher than that of other trauma mechanisms (p<0.001). In earthquake-related cases, multiple fractures were present in 63.2% of patients, and bilateral extremity fractures were observed in 21.4% of cases. The infection rate was 11.4% in patients who received early antibiotic administration, compared to 27.8% in those with delayed administration (p<0.005). Early surgical intervention resulted in an infection rate of 15.2%, whereas delayed intervention showed an infection rate of 31.4% (p=0.002). Amputation rates were found to be 6.4% for the entire patient group, but 41.2% in the Gustilo-Anderson Type IIIC fracture group. Osteomyelitis rate was 18.6% in patients who underwent delayed wound closure, and 35% of these patients required prolonged intravenous antibiotic therapy. CONCLUSION: This study demonstrates that early antibiotic administration, early surgical intervention, and appropriate wound management strategies significantly reduce infection rates in open fractures resulting from high-energy traumas. Particularly, the high complication rates observed in earthquake-related cases highlight the need for systematic and carefully planned approaches in disaster-related patient management. The findings emphasize the importance of optimal surgical timing and proper antibiotic protocols in reducing infection risks and improving clinical outcomes. Further prospective studies are needed to validate these findings.Öğe Pediatric Voluntary Habitual Hip Dislocation: Clinical Characteristics, Family Dynamics, and Long-Term Outcomes-A Retrospective Study(Mdpi, 2025) Yilmaz, Mehmet; Ulusoy, Ibrahim; Tantekin, Mehmet Firat; Guzel, Ismail; Kivrak, AybarsBackground/Objectives: Recurrent hip dislocations are a rare occurrence in pediatric patients. As there are few cases of voluntary habitual dislocation documented in the literature, there is a paucity of information available regarding its pathogenesis, risk factors, and classification. The prognosis for these patients is generally good. A long-term follow-up duration of two years was conducted to evaluate outcomes. Statistical analysis was performed to assess the impact of family structure and treatment approaches on outcomes. Methods: From January 2010 to December 2022, patients with voluntary habitual hip dislocation were retrospectively identified through the hospital information system. Data regarding demographic characteristics, clinical findings, and treatment outcomes were analyzed. A total of 13 patients (14 hips) met the inclusion criteria. Conservative treatment methods, including orthosis and family therapy, were applied. Statistical analysis was performed to assess the impact of family structure and treatment approaches on outcomes. Results: The mean age at diagnosis was 48.7 months, with 77% of cases being female. Posterior dislocation was observed in all cases, and no underlying bone pathology was detected on imaging. The prognosis for these patients is generally good. At the one-year follow-up, 85% of patients achieved a complete resolution of dislocations, increasing to 100% by the two-year follow-up. Patients from larger families demonstrated significantly slower recovery rates at the first- and sixth-month evaluations (p = 0.033 and p = 0.048, respectively), but outcomes were comparable by one year. A unique aspect of this study is the emphasis on family dynamics, which significantly influenced treatment adherence and recovery. Statistical analysis was performed to assess the impact of family structure and treatment approaches on outcomes. Conclusions: Voluntary habitual hip dislocation is a rare condition with good long-term outcomes under conservative management. This study highlights the importance of addressing family dynamics in the treatment plan, especially in larger families, where attention and psychological factors may play a significant role in delayed recovery.Öğe Ultrasound-Guided Percutaneous Release and Mini-Open Surgery in Carpal Tunnel Syndrome: A Comparison of Short- and Long-Term Outcomes(Mdpi, 2025) Ulusoy, Ibrahim; Yilmaz, Mehmet; Tantekin, Mehmet Firat; Guezel, Ismail; Kivrak, AybarsBackground and Objectives: The aim of this study was to compare the short- and long-term effectiveness of ultrasound-guided percutaneous release (CTR-US) and mini-open surgery in the treatment of carpal tunnel syndrome (CTS). Materials and Methods: A retrospective analysis was conducted on 172 patients who underwent surgical treatment for CTS between 2015 and 2020. The patients were divided into two groups: those who underwent CTR-US (Group A, n = 66) and those treated with mini-open surgery (Group B, n = 106). All patients were evaluated using the Boston Carpal Tunnel Questionnaire (BCTQ) and the Quick Disabilities of the Arm, Shoulder, and Hand (QDASH) scores before surgery and at 3 months, 6 months, 1 year, 2 years, and 5 years postoperatively. Electrophysiological and ultrasound findings were also compared. Statistical analyses were performed using t-tests, Mann-Whitney U tests, and Chi-square tests, with significance set at p < 0.05. Results: A total of 172 patients who met the study criteria were included. Among the participants, 112 were women and 60 were men. The mean age was calculated as 61 years for female patients and 54 years for male patients. No significant differences were found between the groups in terms of age, gender, laterality, and disease duration. Both groups demonstrated significant improvements in BCTQ and QDASH scores at all postoperative time points compared to preoperative scores (p < 0.001). The CTR-US group showed advantages in shorter treatment duration (p < 0.001), lower cost (p < 0.05), and faster recovery time. Electrophysiological evaluations revealed faster improvements in distal motor latency (DML) and sensory conduction velocity (SCV) in the CTR-US group (p < 0.05). Ultrasound assessments indicated that both methods achieved effective release of the transverse carpal ligament. No significant differences were observed between the groups in long-term questionnaire scores. Conclusion: CTR-US offers advantages such as shorter treatment duration, lower cost, and faster recovery due to its minimally invasive nature. Consistent with the literature, CTR-US provided faster recovery and improved patient comfort. However, mini-open surgery remains a reliable alternative with long-term symptom control and low complication rates. Our study found that both methods are effective, but CTR-US stands out for its esthetic and functional advantages.
