Yayın Comparison of the Results of Hook Plate and Endo-Button Used in the Surgical Treatment of Acromioclavicular Joint Separation(Springernature, 2020) Unal, Omer Kays; Dağtaş, Mirza ZaferPurpose: Our study aimed to compare the clinical outcomes between endo-button and hook plate fixations for the treatment of acute unstable acromioclavicular (AC) joint dislocation. Materials: A retrospective evaluation of patients with acute AC joint dislocation who were treated between February 2009 and December 2019 was performed. The study was conducted with 39 patients who met the inclusion criteria. Patients were divided into group I, operated with a hook plate, and group 2, operated with an endo-button. The demographic features and postoperative complications were analyzed. The disability of arm, shoulder, and hand (DASH) scoring system, modified University of California at Los Angeles shoulder score (UCLA) scale, and the visual analog scale (VAS) scores were used to evaluate shoulder functions in these patients. Shoulder functions were evaluated one, three, six, and twelve months after surgery. Results: There were 21 patients in group 1 and 18 patients in group 2. Gender distribution was 28 male and 11 female, and the average age was 30.9 years (18-50). There were no significant differences in age, sex, side of injury, or follow-up time from injury to surgery between the two groups. The UCLA scores of group 1 and group 2 one month after surgery were 17.2 and 27.2, respectively. DASH scores of group 1 and group 2 one month after surgery were 82 and 52, respectively. The VAS scores of group 1 and group 2 one month after surgery were 70 and 14, respectively. For all scores at first month post-surgery, there were statistically significant differences between groups, but scores became similar 12 months after surgery. Conclusion: Postoperative shoulder scores of patients with endo-button showed superiority in the early stages. However, after a year of follow-up, the results of the surgery performed with an endo-button or a hook plate were similar.Yayın The external fixation can be a good alternative to plate-screw treatment in the surgical treatment of bilateral distal radius fractures: A retrospective cohort study(Turkish Joint Diseases Foundation, 2021) Dağtaş, Mirza Zafer; Unal, Omer KaysObjectives: We aimed to compare the outcomes of two surgical treatment options, external fixator (EF) or open reduction and internal fixation (ORIF), in patients with bilateral distal radius fractures (DRFs). Patients and methods: Twenty-one patients (11 males 10 females; mean age: 40.0 +/- 16.0 years; range, 20 to 67 years) who underwent ORIF (n=10) or EF (n=11) due to bilateral DRF at between January 2011 and December 2019 were retrospectively analyzed. The Quick Disability of the Arm, Shoulder and Hand (Q-DASH) was used to calculate functional and symptomatic evaluation. The MAYO wrist scores were used to evaluate pain, functional status, ROM, and grip strength and the Michigan Hand Outcomes Questionnaire (MHOQ) was used to measure hand performance in daily life. Results: The operation time was statistically significantly longer in the ORIF group, compared to the EF group (p<0.001). Radial shortening was statistically significantly greater in the EF group, compared to the ORIF group (p<0.001). While the Q-DASH score was lower in the EF group on Day 15 and at one and two months (p<0.001, for each), it was similar between the groups at one year (p=0.507). The MAYO wrist score was higher in the EF group on Day 15 and at one and two months and one year (p<0.05, for each). While the MHOQ score was higher in the EF group on Day 15 and at one and two months (p<0.001, for each), it was similar between the groups at one year (p=0.557). Conclusion: In bilateral DRF cases, hand functions in the first two months after treatment were better in the EF group, compared to the ORIF group. This functional difference between the two groups gradually decreased in the first year and reached similar levels. Our results demonstrate that EF can be a good alternative in the surgical treatment of bilateral DRFs owing to its acceptable results, particularly in the short-term.Yayın Long-Term Outcome of Electrodiagnostic Values and Symptom Improvement After Carpal Tunnel Release: A Retrospective Cohort Study(W B Saunders Co-Elsevier Inc, 2022) Dağtas, Mirza Zafer; Unal, Omer Kays[Abstract Not Available]Yayın A NEW FLUOROSCOPY TECHNIQUE FOR SUPRACONDYLAR HUMERUS FRACTURES(Atha Comunicacao & Editora, 2022) Dağtaş, Mirza Zafer; Unal, Omer KaysIntroduction: To compare two different intraoperative fluoroscopy techniques used for closed reduction and percutaneous pinning (CRPP) in pediatric patients with supracondylar humerus fractures (SHF). Materials and Methods: Thirty-six patients who underwent SHF surgery from May 2011 to June 2019 were included in the study. During surgery, the classical fluoroscopy method (CFM) was used in 21 patients and the new fluoroscopy method (NFM) was used in the remaining 15 patients. Results: The mean age was 5.14 +/- 1.13 years in the NFM group and 5.38 +/- 1.36 years in the CFM group. Mean operative time was 38.14 +/- 5.92 minutes in the CFM group and 21.54 +/- 3.48 minutes in the NFM group (p=0.001), while mean fluoroscopy times were 25.65 +/- 3.91 seconds and 39.84 +/- 7.50 seconds in the NFM and CFM groups, respectively (p=0.001). The NFM and CFM groups demonstrated similar functional capacity as measured by the Mayo Elbow Score (p=0.168). Direct radiographs obtained to measure Baumann's angle also showed that the two groups had similar results (p=0.848). Conclusions: The NFM is a reliable and successful technique as it leads to shorter operative and fluoroscopy times, as well as providing improvement in functional scores and radiological outcomes in short-term follow-up.Yayın A novel modification to ultrasound guided lumbar erector spinae plane block: Tulgar approach(ELSEVIER SCIENCE INC, 2019) Tulgar, Serkan; Unal, Omer Kays; Thomas, David Terence; Ozer, Zeliha…Yayın Using autograft in the surgical treatment of isolated distal ulna fractures with open reduction internal fixation improves short-term clinical outcomes: 11 years of experience(Elsevier Masson, Corp Off, 2021) Dağtaş, Mirza Zafer; Unal, Omer KaysBackground: Most of the studies on ulna fractures assess the treatment of fractures accompanied by other tissue injuries; thus, the number of studies focused directly on isolated distal ulna fractures are very few. In this study, it was aimed to evaluate the short-term results of open reduction internal fixation (ORIF) and autograft + ORIF approaches in the treatment of isolated distal ulna fractures. Hypothesis: Using autograft in the surgical treatment of isolated distal ulna fractures with open reduction internal fixation improves short-term clinical outcomes. Patients and methods: The records of isolated distal ulna fractures (distal one-third) operated at the Mal-tepe University Hospital Orthopedics and Traumatology Clinic between January 2009 and December 2019 were retrospectively reviewed. The cases were divided into two groups according to surgical approach, ORIF (n = 40) or autograft + ORIF (n = 34). Results: The mean age was 41.55 +/- 12.42 years. 52.7% of the cases were female, 67.6% of the fractures were right-sided, and 37.8% of the traumas causing the fracture were high-energy trauma. There was no significant difference between the ORIF and autograft + ORIF groups in terms of age, gender, side and severity of trauma (p > 0.05). It was found that pseudoarthrosis development was significantly more prevalent in the ORIF group (25%) compared to the autograft + ORIF group (5.9%) (p = 0.026). The median (1st quartile-3rd quartile) time to union was 16 (14-17) weeks in the ORIF group, and 9.5 (8.5-12) weeks in the autograft + ORIF group. Compared to ORIF, the time to union was significantly shorter with the autograft + ORIF procedure (p < 0.001). At both the 3rd and 12th month follow-up examinations, the autograft + ORIF group was found to have significantly higher MAYO score and grip strength, and lower DASH score, compared to the ORIF group. Discussion: When an autograft is used in addition to ORIF in the surgical treatment of isolated distal ulna fractures, the bone heals faster, pseudoarthrosis develops less frequently, and short-term (3rd and 12th months) functional results are better.
